  • Another aspect of the present invention is directed to the use of a peptide for prophylaxis and/or treatment of prion diseases.
  • Prions are infectious agents which do not have a nucleic acid genome. It seems that a protein alone is the infectious agent. A prion has been defined as "small proteinaceous infectious particle which resists inactivation by procedures that modify nucleic acids". The discovery that proteins alone can transmit an infectious disease came as a considerable surprise to the scientific community. Prion diseases are often called “transmissible spongiform encephalopathies", because of the post mortem appearance of the brain with large vacuoles in the cortex and cerebellum. Probably most mammalian species develop these diseases. Prion diseases are a group of neurodegenerative disorders of humans and animals and the prion diseases can manifest as sporadic, genetic or infectious disorders.
  • prion diseases acquired by exogenous infection are bovine spongiform encephalitis (BSE) of cattle and the new variant of Creutzfeld-Jakob disease (vCJD) caused by BSE as well as scrapie of animals.

  • human prion diseases include kuru, sporadic Creutzfeldt-Jakob disease (sCJD), familial CJD (fCJD), iatrogenic CJD (iCJD), Gerstmann-Straussler-Scheinker (GSS) disease, fatal familial insomnia (FFI), and especially the new variant CJD (nvCJD or vCJD).
  • prion is used to describe the causative agents which underlie the transmissible spongiform encephalopathies.
  • a prion is proposed to be a novel infectious particle that differs from viruses and viroids. It is composed solely of one unique protein that resists most inactivation procedures such as heat, radiation, and proteases. The latter characteristic has led to the term protease-resistant isoform of the prion protein. The protease-resistant isoform has been proposed to slowly catalyze the conversion of the normal prion protein into the abnormal form.
  • isoform in the context of prions means two proteins with exactly the same amino acid sequence that can fold into molecules with dramatically different tertiary structures.
  • the normal cellular isoform of the prion protein (PrP c ) has a high ⁇ -helix content, a low ⁇ -sheet content, and is sensitive to protease digestion.
  • the abnormal, disease-causing isoform (PrP Sc ) has a lower ⁇ -helix content, a much higher ⁇ -sheet content, and is much more resistant to protease digestion.

  • Autoimmune disease refers to any of a group of diseases or disorders in which tissue injury is associated with a humoral and/or cell-mediated immune response to body constituents or, in a broader sense, an immune response to self.

  • inflammation caused by immune complexes in the joints arthritis
  • the kidneys glomerulonephritis
  • blood vessels vaculitis
  • Increased immune complex formation correlates with the presence of antibodies directed to self or so-called autoantibodies, and the presence of the latter can also contribute to tissue inflammation either as part of an immune complex or unbound to antigen (free antibody).
  • autoimmune diseases the presence of free autoantibody contributes significantly to disease pathology. This has been clearly demonstrated for example in SLE (anti-DNA antibodies), immune thrombocytopenia (antibody response directed to platelets), and to a lesser extent rheumatoid arthritis (IgG reactive rheumatoid factor).
  • SLE anti-DNA antibodies
  • immune thrombocytopenia immune response directed to platelets
  • IgG reactive rheumatoid factor IgG reactive rheumatoid factor
  • the important role of immune complexes and free autoantibodies is further demonstrated by the fact that successful treatment of certain autoimmune diseases has been achieved by the removal of immune complexes and free antibody by means of specific immunoadsorption procedures. For example, the use of an apheresis procedure in which immune complexes and antibodies are removed by passage of a patient's blood through an immunoaffinity column was approved by the U.S.
  • proinflammatory cytokines such as tumor necrosis factor ⁇ (TNF ⁇ ) and interleukin-1 (IL-1 ) play a protective role in the response to infection and cellular stress.
  • TNF ⁇ tumor necrosis factor ⁇
  • IL-1 interleukin-1
  • the pathological consequences which result from chronic and/or excessive production of TNF ⁇ and IL-1 are believed to underlie the progression of many autoimmune diseases such as rheumatoid arthritis, Crohn's disease, inflammatory bowel disease, and psoriasis.
  • Other proinflammatory cytokines include interleukin-6, interleukin-8, interleukin-17, and granulocyte-macrophage colony stimulating factor.
  • CD4+CD25+ regulatory T cells play a critical role in the control of periphery tolerance to self-antigens. Interestingly, they also control immune responses to allergens and transplant antigens. Recent studies in animal models have shown that adoptive transfer of CD4+CD25+ Tregs can prevent or even cure allergic and autoimmune diseases, and appear to induce transplantation tolerance. Thus, adoptive cell therapy using patient-specific CD4+CD25+ Tregs has emerged as an individualized medicine for the treatment of inflammatory disease including allergy, autoimmune disease and transplant rejection. Furthermore, strategies to activate and expand antigen-specific CD4+CD25+ Tregs in vivo using pharmacological agents may represent a novel avenue for drug development.
  • leukocytes The interaction of leukocytes with the vessel endothelium to facilitate the extravasation into the tissue represents a key process of the body's defense mechanisms. Excessive recruitment of leukocytes into the inflamed tissue in chronic diseases like autoimmune disorders could be prevented by interfering with the mechanisms of leukocyte extravasation. Significant progress in elucidating the molecular basis of the trafficking of leukocytes from the blood stream to the extravascular tissue has been achieved that enables new strategies for therapeutic approaches. The multistep process of leukocyte rolling, firm adhesion and transmigration through the endothelial wall is facilitated by a dynamic interplay of adhesion receptors on both leukocytes and on endothelial cells as well as chemokines.

This is consistent with the critical importance of this cytokine in diverse models of fibrosis in various tissues. In view of these properties, the persistence or prolonged survival of the myofibroblast may be the key to understanding why certain forms of lung injury may result in progressive disease, terminating in end stage disease.

  • Inflammation is the final common pathway of various insults, such as infection, trauma, and allergies to the human body. It is characterized by the activation of the immune system with recruitment of inflammatory cells, production of pro- inflammatory cells and production of pro-inflammatory cytokines. Most inflammatory diseases and disorders are characterized by abnormal accumulation of inflammatory cells including monocytes/macrophages, granulocytes, plasma cells, lymphocytes and platelets. Along with tissue endothelial cells and fibroblasts, these inflammatory cells release a complex array of lipids, growth factors, cytokines and destructive enzymes that cause local tissue damage.

  • T lymphocytes are a major source of cytokines. These cells bear antigen specific receptors on their cell surface to allow recognition of foreign pathogens. They can also recognize normal tissue during episodes of autoimmune diseases. There are two main subsets of T lymphocytes, distinguished by the presence of cell surface molecules known as CD4 and CD8. T lymphocytes expressing CD4 are also known as helper T cells, and these are regarded as being the most prolific cytokine producers. This subset can be further subdivided into Th1 and Th2, and the cytokines they produce are known as Th1-type cytokines and Th2-type cytokines.
  • Th 1 -type cytokines tend to produce the pro-inflammatory responses responsible for killing intracellular parasites and for perpetuating autoimmune responses. Interferon gamma is the main Th1 cytokine. Excessive pro-inflammatory responses can lead to uncontrolled tissue damage, so there needs to be a mechanism to counteract this.
  • the Th2-type cytokines include lnterleukin 4, lnterleukin 5, and lnterleukin 13, which are associated with the promotion of IgE and eosinophilic responses in atopy, and also lnterleukin-10, which has more of an anti-inflammatory response. In excess, Th2 responses will counteract the Th1 mediated microbicidal action. The optimal scenario would therefore seem to be that humans should produce a well balanced Th1 and Th2 response, suited to the immune challenge.
  • Th2 weighted imbalance Allergy is regarded as a Th2 weighted imbalance. Pregnancy and early postnatal life are also viewed as Th2 phenomena (to reduce the risk of miscarriage, a strong Th2 response is necessary to modify the Th1 cellular response in utero).
  • Th2 phenomena to reduce the risk of miscarriage, a strong Th2 response is necessary to modify the Th1 cellular response in utero.
  • the fetus can switch on an immune response early in pregnancy, and because pregnancy is chiefly a Th2 situation, babies tend to be born with Th2 biased immune responses. These can be switched off rapidly postnatally under the influence of microbiological exposure or can be enhanced by early exposure to allergens.
  • Th1 cells produce interferon-gamma, lnterleukin 2, and tumor necrosis factor-beta, which activate macrophages and are responsible for cell-mediated immunity and phagocyte-dependent protective responses.
  • Th2 cells produce cytokines which are responsible for strong antibody production, eosinophil activation, and inhibition of several macrophage functions, thus providing phagocyte-independent protective responses.
  • Th1 cells mainly develop following infections by intracellular bacteria and some viruses, whereas Th2 cells predominate in response to infestations by gastrointestinal nematodes.
  • Polarized Th1 and Th2 cells not only exhibit different functional properties, but also show the preferential expression of some activation markers and distinct transcription factors.
  • Th cell differentiation Several mechanisms may influence the Th cell differentiation, which include the cytokine profile of "natural immunity” evoked by different offending agents, the nature of the peptide ligand, as well as the activity of some costimulatory molecules and microenvironmentally secreted hormones, in the context of the individual genetic background.

Although the concentration of glutamate can reach the millimolar range in nerve terminals its extracellular concentration is maintained at a low level to prevent neurotoxicity.

  • Angiogenesis is a physiological process involving the growth of new blood vessels from pre-existing vessels.
  • Angiogenesis is a normal process in growth and development, as well as in wound healing. However, this is also a fundamental step in the transition of tumors from a dormant state to a malignant state.
  • Angiogenesis occurs in several well-characterized stages.
  • biological signals known as angiogenic growth factors activate receptors present on endothelial cells present in pre-existing blood vessels.
  • the activated endothelial cells begin to release enzymes called proteases that degrade the basement membrane in order to allow endothelial cells to escape from the original (parent) vessel walls.
  • proteases enzymes that degrade the basement membrane in order to allow endothelial cells to escape from the original (parent) vessel walls.
  • the endothelial cells then proliferate into the surrounding matrix and form solid sprouts connecting neighboring vessels.
  • sprouts extend toward the source of the angiogenic stimulus, endothelial cells migrate, using adhesion molecules, called integrins. These sprouts then form loops to become a full-fledged vessel lumen as cells migrate to the site of angiogenesis.
  • Sprouting occurs at a rate of several millimeters per day, and enables new vessels to grow across gaps in the vasculature.
  • Therapeutic angiogenesis is the application of specific compounds which may inhibit or induce the creation of new blood vessels in the body in order to combat disease.
  • the presence of blood vessels where there should be none may affect the mechanical properties of a tissue, increasing the likelihood of failure.
  • the absence of blood vessels in a repairing or otherwise metabolically active tissue may retard repair or some other function.
  • Several diseases are the result of failure or insufficient blood vessel formation and may be treated by a local expansion of blood vessels, thus bringing new nutrients to the site, facilitating repair.
  • Other diseases may be created by a local expansion of blood vessels, interfering with normal physiological processes.
  • Angiogenesis represents an excellent therapeutic target for the treatment of, for example, cardiovascular diseases. It is a potent, physiological process that underlies the natural manner in which the human body responds to a diminution of blood supply to vital organs, namely the production of new collateral vessels to overcome the ischemic insult.
  • angiogenesis The modern clinical application of the principle "angiogenesis" can be divided into two main areas:
  • Vasculitis and excessive angiogenesis in autoimmune disorders such as systemic sclerosis (Scleroderma), multiple sclerosis, Sjogren's disease,
  • Vascular malformations in blood and lymph vessels like DiGeorge syndrome, hereditary haemorrhagic telangiectasia, cavernous hemangioma, cutaneous hemangioma, lymphatic malformations, transplant arteriopathy, atherosclerosis, vascular anastomoses, • Adipose tissue in obesity,
  • Lung diseases like any type of pulmonary hypertension, asthma, nasal polyps, rhinitis, chronic airway inflammation and obstruction (COPD), cystic fibrosis, acute lung injury, bronchiolitis obliterans organizing pneumonia,
  • COPD chronic airway inflammation and obstruction
  • Gastrointestinal tract diseases like inflammatory bowel disease, periodontal disease, ascites, peritoneal adhesions, liver cirrhoses,
  • Reproductive system diseases like endometriosis, uterine bleeding, ovarian cysts, ovarian hyperstimulation, • Bone and joint diseases like arthritis and synovitis, osteomyelitis, osteophyte formation, HIV-induced bone marrow angiogenesis,
  • Nervous system diseases like Alzheimer's disease, amyotrophic lateral sclerosis, diabetic neuropathy, stroke,
  • Kidney diseases like nephropathy, glomerulosclerosis, tubulointerstitial fibrosis,
  • Angiogenesis research is also a cutting edge field in cancer research, and traditional therapies, such as radiation therapy, may work in part by targeting the genomically stable endothelial cell compartment, rather than the genomically unstable tumor cell compartment.
  • New blood vessel formation is a relatively fragile process, subject to disruptive interference at several levels.
  • the therapy is the selection agent which is being used to kill a cell compartment.
  • Tumor cells evolve resistance rapidly due to rapid generation time (days) and genomic instability (variation), whereas endothelial cells are a good target because of a long generation time (months) and genomic stability (low variation).
  • Angiogenesis-based tumour therapy relies on natural and synthetic angiogenesis inhibitors like angiostatin, endostatin and tumstatin. These are proteins that mainly originate as specific fragments pre-existing structural proteins like collagen or plasminogen.
  • vascular grafts In addition, in terms of tissue engineering, medicaments that influence angiogenesis in vascular grafts are needed. More than 450,000 vascular grafts were used in coronary bypass surgeries annually. Other uses for vascular grafts include treatments for blood vessel aneurysms and fistulas, as well as replacements for diseased arteries in other locations in the body. When possible, the best choice for a replacement vessel is an autograft, where sections of the patient's healthy blood vessels (usually veins) are harvested and implanted in the required location. Many patients, however, especially those with pre-existing vascular disease or patients that have already had autograft procedures, do not have blood vessels that are healthy enough to adequately serve as replacements.
  • the most common form of treatment has been the use of synthetic polymeric materials, like ePTFE (extended polytetrafluoroethylene) and Dacron (poly[ethylene terephthalate]), to form either permanent or resorbable replacements for the damaged vessels.
  • synthetic polymeric materials like ePTFE (extended polytetrafluoroethylene) and Dacron (poly[ethylene terephthalate]
  • the synthetic material has been effective.
  • the synthetic materials cannot be used due to high rates of stenosis and thrombus formation.
  • One possible solution is to use natural materials like collagen, either modified or combined with a synthetic material, to form a graft that more closely mimics the body's natural function and has low thrombogenicity and low incidence of stenosis.
  • the host response can be modulated to help insure that the graft will not fail.
  • collagen as a material for a synthetic vascular graft is quite promising because it is biodegradable and has good mechanical properties. Since collagen is biodegradable, as the device degrades tissue can grow into the device. This is advantageous because ideally as the collagen implant degrades the newly formed tissue will replace it, which results in a gradual transfer of stress from the implanted device to the newly formed tissue.
  • endothelial cells have been cultured onto the collagen small diameter vascular grafts. Therefore by incorporating biodegradable peptides into the collagen vascular implant material, endothelial cells can be seeded onto the top of the material to create a lumenal surface that is comprised of endothelial cells to more closely mimic the natural biological environment. Migration of endothelial cells on biomaterials is very important for the development of implantable devices. These cell property controls the rates of reendothelization and angiogenesis that are important for the success of the implant.
  • Angiogenesis is a complex, multi-stage process by which new blood vessels are formed from pre-existing vasculature. Two critical steps in this process are endothelial cell migration and assembly into new tubules. Over the last decade, diverse arrays of molecular regulators that participate in the process of angiogenesis have been identified.
  • the receptor tyrosine kinases for example, are one such family of angiogenesis regulators that play a prominent role in endothelial cell assembly and migration.

Description

Use of a peptide as a therapeutic agent
Specification
The present invention is directed to the use of the peptide compounds Ac-Ala-Asp- Lys-Pro-Asp-Met-Gly-Glu-lle-Ala-Ser-Phe-Asp-Lys-Ala-Lys-Leu-Lys-Lys-Thr-Glu-Thr- Gln-Glu-Lys-Asn-Thr-Leu-Pro-Thr-Lys-Glu-Thr-lle-Glu-Gln-Glu-Lys-Arg-Ser-Glu-lle- Ser-OH (Thymosin beta 10) and Ac-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-lle-Thr- Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-OH (Thymosin alpha"! ) as a therapeutic combination for the prophylaxis and/or treatment of cancer, an autoimmune disease, an infectious disease, a fibrotic disease, an inflammatory disease, a neurodegenerative disease, or a heart and vascular disease.
Background of the invention
The identification of a therapeutic compound effective for the prophylaxis and/or treatment of a disease can be based on the activity of the compound in a biological assay. A biological assay that mimics a disease causative mechanism can be used to test the therapeutic activity of a candidate peptide.
The causative mechanism of many diseases is the over activity of a biological pathway. A peptide that can reduce the activity of the biological pathway can be effective in the prophylaxis and/or treatment of the disease caused by the over activity of the biological pathway. Similarly the causative mechanism of many diseases is the over production of a biological molecule. A peptide that can reduce the production of the biological molecule or block the activity of the over produced biological molecule can be effective in the prophylaxis and/or treatment of the disease caused by the over production of the biological molecule.
Conversely, the causative mechanism of many diseases is the under activity of a biological pathway. A peptide that can increase the activity of the biological pathway can be effective in the prophylaxis and/or treatment of the disease caused by the under activity of the biological pathway. Also similarly the causative mechanism of many diseases is the under production of a biological molecule. A peptide that can increase the production of the biological molecule or mimic the biological activity of the under produced biological molecule can be effective in the prophylaxis and/or treatment of the disease caused by the under production of the biological molecule.
It is the object of the present invention to provide a compound for the prophylaxis and/or treatment of cancer, autoimmune diseases, fibrotic diseases, inflammatory diseases, neurodegenerative diseases, infectious diseases, lung diseases, heart and vascular diseases and metabolic diseases.
The object of the present invention is solved by the teaching of the independent claims. Further advantageous features, aspects and details of the invention are evident from the dependent claims, the description, and the examples of the present application.

Infectious disease
The immune system in higher vertebrates represents the first line of defense against various antigens that can enter the vertebrate body, including microorganisms such as bacteria, fungi and viruses that are the causative agents of a variety of diseases.
Despite large immunization programs, viral infections, such as influenza virus, human immunodeficiency virus ("HIV"), herpes simplex virus ("HSV", type 1 or 2), human papilloma virus ("HPV", type 16 or 18), human cytomegalovirus ("HCMV") or human hepatitis B or C virus ("HBV", Type B; "HCV", type C) infections, remain a serious source of morbidity and mortality throughout the world and a significant cause of illness and death among people with immune-deficiency associated with aging or different clinical conditions. Although antiviral chemotherapy with compounds such as amantadine and rimantadine have been shown to reduce the duration of symptoms of clinical infections (i.e., influenza infection), major side effects and the emergence of drug-resistant variants have been described. New classes of antiviral agents designed to target particular viral proteins such as influenza neuraminidase are being developed. However, the ability of viruses to mutate the target proteins represents an obstacle for effective treatment with molecules which selectively inhibit the function of specific viral polypeptides. Thus, there is need for new therapeutic strategies to prevent and treat viral infections.
Additionally, there is a need for new therapies for the prevention and treatment of bacterial infections, especially bacterial infections caused by multiple drug resistant bacteria. Currently, bacterial infections are treated with various antibiotics. Although antibiotics have and can be effective in the treatment of various bacterial infections, there are a number of limitations to the effectiveness and safety of antibiotics. For example, some individuals have an allergic reaction to certain antibiotics and other individuals suffer from serious side effects. Moreover, continued use of antibiotics for the treatment of bacterial infections contributes to formation of antibiotic-resistant strains of bacteria.
Another aspect of the present invention is directed to the use of a peptide for prophylaxis and/or treatment of infectious diseases including opportunistic infections.
Examples of infectious diseases are AIDS, alveolar hydatid disease (AHD, echinococcosis), amebiasis (Entamoeba histolytica infection), Angiostrongylus infection, anisakiasis, anthrax, babesiosis (Babesia infection), Balantidium infection (balantidiasis), Baylisascaris infection (raccoon roundworm), bilharzia (schistosomiasis), Blastocystis hominis infection (blastomycosis), boreliosis, botulism, Brainerd diarrhea, brucellosis, bovine spongiform encephalopathy (BSE), candidiasis, capillariasis (Capillaria infection), chronic fatigue syndrome (CFS), Chagas disease (American trypanosomiasis), chickenpox (Varicella-Zoster virus), Chlamydia pneumoniae infection, cholera, Creutzfeldt-Jakob disease (CJD), clonorchiasis (Clonorchis infection), cutaneous larva migrans (CLM) (hookworm infection), coccidioidomycosis, conjunctivitis, Coxsackievirus A16 (hand, foot and mouth disease), cryptococcosis, Cryptosporidium infection (cryptosporidiosis), Culex mosquito (West Nile virus vector), cyclosporiasis (Cyclospora infection), cysticercosis (neurocysticercosis), Cytomegalovirus infection, Dengue / Dengue fever, Dipylidium infection (dog and cat flea tapeworm), Ebola virus hemorrhagic fever, encephalitis, Entamoeba coli infection, Entamoeba dispar infection, Entamoeba hartmanni infection, Entamoeba histolytica infection (amebiasis), Entamoeba polecki infection, enterobiasis (pinworm infection), enterovirus infection (non-polio), Epstein-Barr virus infection, Escherichia coli infection, foodborne infection, foot and mouth disease, fungal dermatitis, gastroenteritis, group A streptococcal disease, group B streptococcal disease, Hansen's disease (leprosy), Hantavirus pulmonary syndrome, head lice infestation (pediculosis), Helicobacter pylori infection, hematologic disease, Hendra virus infection, hepatitis (HCV, HBV), herpes zoster (shingles), HIV Infection, human ehrlichiosis, human parainfluenza virus infection, influenza, isosporiasis (Isospora infection), Lassa fever, leishmaniasis, Kala-azar (Kala-azar, Leishmania Infection), lice (body lice, head lice, pubic lice), Lyme disease, malaria, Marburg hemorrhagic fever, measles, meningitis, mosquito-borne diseases, Mycobacterium avium complex (MAC) infection, Naegleria infection, nosocomial infections, nonpathogenic intestinal ameobae infection, onchocerciasis (river blindness), opisthorciasis (Opisthorcis infection), parvovirus infection, plague, Pneumocystis carinii pneumonia (PCP), polio, Q fever, rabies, respiratory syncytial virus (RSV) Infection, rheumatic fever, Rift Valley fever, river blindness (onchocerciasis), rotavirus infection, roundworm infection, salmonellosis, salmonella enteritidis, scabies, shigellosis, shingles, sleeping sickness, smallpox, streptococcal Infection, tapeworm infection (Taenia infection), tetanus, toxic shock syndrome, tuberculosis, ulcers (peptic ulcer disease), valley fever, Vibrio parahaemolyticus infection, Vibrio vulnificus infection, viral hemorrhagic fever, warts, waterborne infectious diseases, West Nile virus infection (West Nile encephalitis), whooping cough, yellow fever.
Another aspect of the present invention is directed to the use of a peptide for prophylaxis and/or treatment of prion diseases.
Prions are infectious agents which do not have a nucleic acid genome. It seems that a protein alone is the infectious agent. A prion has been defined as "small proteinaceous infectious particle which resists inactivation by procedures that modify nucleic acids". The discovery that proteins alone can transmit an infectious disease came as a considerable surprise to the scientific community. Prion diseases are often called "transmissible spongiform encephalopathies", because of the post mortem appearance of the brain with large vacuoles in the cortex and cerebellum. Probably most mammalian species develop these diseases. Prion diseases are a group of neurodegenerative disorders of humans and animals and the prion diseases can manifest as sporadic, genetic or infectious disorders. Examples of prion diseases acquired by exogenous infection are bovine spongiform encephalitis (BSE) of cattle and the new variant of Creutzfeld-Jakob disease (vCJD) caused by BSE as well as scrapie of animals. Examples of human prion diseases include kuru, sporadic Creutzfeldt-Jakob disease (sCJD), familial CJD (fCJD), iatrogenic CJD (iCJD), Gerstmann-Straussler-Scheinker (GSS) disease, fatal familial insomnia (FFI), and especially the new variant CJD (nvCJD or vCJD). The name "prion" is used to describe the causative agents which underlie the transmissible spongiform encephalopathies. A prion is proposed to be a novel infectious particle that differs from viruses and viroids. It is composed solely of one unique protein that resists most inactivation procedures such as heat, radiation, and proteases. The latter characteristic has led to the term protease-resistant isoform of the prion protein. The protease-resistant isoform has been proposed to slowly catalyze the conversion of the normal prion protein into the abnormal form.
The term "isoform" in the context of prions means two proteins with exactly the same amino acid sequence that can fold into molecules with dramatically different tertiary structures. The normal cellular isoform of the prion protein (PrPc) has a high α-helix content, a low β-sheet content, and is sensitive to protease digestion. The abnormal, disease-causing isoform (PrPSc) has a lower α-helix content, a much higher β-sheet content, and is much more resistant to protease digestion.
As used herein the term "prion diseases" refers to transmissible spongiform encephalopathies. Examples for prion diseases comprise scrapie (sheep, goat), transmissible mink encephalopathy (TME; mink), chronic wasting disease (CWD; muledeer, deer, elk), bovine spongiform encephalopathy (BSE; cows, catties), Creutzfeld-Jacob Disease (CJD), variant CJD (vCJD), sporadic Creutzfeldt-Jakob disease (sCJD), familial CJD (fCJD), iatrogenic CJD (iCJD, Gerstmann-Straussler- Scheinker syndrome (GSS), fatal familial insomnia (FFI), and kuru. Preferred are BSE, vCJD, and CJD.
The peptides and peptide combination of the present invention were tested using the assays described in Examples 1-7 for their effect as active therapeutic agents in the prophylaxis and/or treatment of infectious diseases and disorders.
Autoimmune disease Autoimmune disease refers to any of a group of diseases or disorders in which tissue injury is associated with a humoral and/or cell-mediated immune response to body constituents or, in a broader sense, an immune response to self. The pathological immune response may be systemic or organ specific. That is, for example, the immune response directed to self may affect joints, skin, myelin sheath that protects neurons, kidney, liver, pancreas, thyroid, adrenals, and ovaries.
In fact, the list of autoimmune diseases is composed of more than eighty disorders. A few autoimmune diseases such as vitiligo, in which patches of skin lose pigmentation, are merely annoying. Most others are debilitating, often progressive with time and eventually fatal. Systemic lupus erythematosus (SLE), for example, is a chronic disease in which 10-15% of patients die within a decade of diagnosis, in all but a few autoimmune diseases, the sex ratio skews towards women. For example, in SLE the ratio of female to male patients is nine to one. In one particular case, Hashimoto's disease in which the immune system attacks the thyroid gland, the ratio is fifty to one.
It has long been known that immune complex formation plays a role in the etiology and progression of autoimmune disease. For example, inflammation in patients with arthritis has long been considered to involve phagocytosis by leukocytes of complexes of antigen, antibody and complement-immune complexes. However, only now it is being recognized that inflammation caused by immune complexes in the joints (arthritis), the kidneys (glomerulonephritis), and blood vessels (vasculitis) is a major cause of morbidity in autoimmune diseases. Increased immune complex formation correlates with the presence of antibodies directed to self or so-called autoantibodies, and the presence of the latter can also contribute to tissue inflammation either as part of an immune complex or unbound to antigen (free antibody). In some autoimmune diseases, the presence of free autoantibody contributes significantly to disease pathology. This has been clearly demonstrated for example in SLE (anti-DNA antibodies), immune thrombocytopenia (antibody response directed to platelets), and to a lesser extent rheumatoid arthritis (IgG reactive rheumatoid factor). The important role of immune complexes and free autoantibodies is further demonstrated by the fact that successful treatment of certain autoimmune diseases has been achieved by the removal of immune complexes and free antibody by means of specific immunoadsorption procedures. For example, the use of an apheresis procedure in which immune complexes and antibodies are removed by passage of a patient's blood through an immunoaffinity column was approved by the U.S. FDA in 1987 for immune thrombocytopenia (ITP) and in 1999 for rheumatoid arthritis. However, currently there is no approved method for the treatment of autoimmune diseases which facilitates the elimination of immune complexes and autoantibodies by administration of a drug.
Another aspect of the etiology and progression of autoimmune disease is the role of proinflammatory cytokines. Under normal circumstances, proinflammatory cytokines such as tumor necrosis factor α (TNFα) and interleukin-1 (IL-1 ) play a protective role in the response to infection and cellular stress. However, the pathological consequences which result from chronic and/or excessive production of TNFα and IL-1 are believed to underlie the progression of many autoimmune diseases such as rheumatoid arthritis, Crohn's disease, inflammatory bowel disease, and psoriasis. Other proinflammatory cytokines include interleukin-6, interleukin-8, interleukin-17, and granulocyte-macrophage colony stimulating factor.
Naturally occurring CD4+CD25+ regulatory T cells (Tregs) play a critical role in the control of periphery tolerance to self-antigens. Interestingly, they also control immune responses to allergens and transplant antigens. Recent studies in animal models have shown that adoptive transfer of CD4+CD25+ Tregs can prevent or even cure allergic and autoimmune diseases, and appear to induce transplantation tolerance. Thus, adoptive cell therapy using patient-specific CD4+CD25+ Tregs has emerged as an individualized medicine for the treatment of inflammatory disease including allergy, autoimmune disease and transplant rejection. Furthermore, strategies to activate and expand antigen-specific CD4+CD25+ Tregs in vivo using pharmacological agents may represent a novel avenue for drug development.
The interaction of leukocytes with the vessel endothelium to facilitate the extravasation into the tissue represents a key process of the body's defense mechanisms. Excessive recruitment of leukocytes into the inflamed tissue in chronic diseases like autoimmune disorders could be prevented by interfering with the mechanisms of leukocyte extravasation. Significant progress in elucidating the molecular basis of the trafficking of leukocytes from the blood stream to the extravascular tissue has been achieved that enables new strategies for therapeutic approaches. The multistep process of leukocyte rolling, firm adhesion and transmigration through the endothelial wall is facilitated by a dynamic interplay of adhesion receptors on both leukocytes and on endothelial cells as well as chemokines. In preclinical studies using various animal models, promising results have been obtained demonstrating that blocking of adhesion receptors of the selectin and integrin families improved the inflammation process in models of ulcerative colitis, autoimmune encephalomyelitis or contact hypersensitivity. In addition to the targeting of adhesion receptors by antibodies, small molecules that mimic epitopes of adhesion receptor ligands have been developed and successfully applied in animal models. Clinical studies revealed a limited response using antibodies to selectins or leukocyte function-associated antigen 1 (LFA-1 ) integrins compared with animal models. However, using humanized antibodies to the alpha 4-integrin subunit significant efficacy has been demonstrated in autoimmune diseases like psoriasis, multiple sclerosis and inflammatory bowel disease.
Examples of autoimmune diseases of the eyes are idiopathic opticus-neuritis, ophthalmia sympathica, anterior uveitis and other uveitis forms, retina degeneration, and Mooren's ulcer. Examples of autoimmune diseases of the skin are bullous pemphigoides, chronic urticaria (autoimmune subtype), dermatitis herpetiformis (morbus Duhring), epidermolysis bullosa aquisita (EBA), acquired angioedema, herpes gestationes, hypocomplementemic urticarial vasculitis syndrome (HUVS), linear IgA-dermatosis, and pemphigus.

During the last decade, new biotherapies have been developed for the treatment of systemic autoimmune diseases. The targets of these new treatments are all the steps of the immune response. These new therapies are: B lymphocyte (BL) inhibitors such as anti-CD20 monoclonal antibody, B lymphocyte stimulator (BLyS) antagonists and tolerogens of pathogenic-antibody secreting LB; inhibitors of the costimulation between antigen-presenting cells and T lymphocyte (TL) like monoclonal anti-CD40 ligand antibody or CTLA4-lg (abatecept); TL antagonists which can inhibit the proliferation of autoreactive T cells; cytokine antagonists; chemokine and adhesin antagonists which inhibit trafficking of immunocompetent cells to target organs. These new approaches are based on a better understanding of the autoimmune response.
The peptides of the present invention were tested using the assays described in Examples 14 - 15 for their effect as active therapeutic agents in the prophylaxis and/or treatment of autoimmune diseases and disorders.

Fibrotic diseases and disorders include, but are not limited to, collagen disease, interstitial lung disease, human fibrotic lung disease (e.g., obliterative bronchiolitis, idiopathic pulmonary fibrosis, pulmonary fibrosis from a known etiology, tumor stroma in lung disease, systemic sclerosis affecting the lungs, Hermansky-Pudlak syndrome, coal worker's pneumoconiosis, asbestosis, silicosis, chronic pulmonary hypertension, AIDS associated pulmonary hypertension, sarcoidosis, and the like), fibrotic vascular disease, tubulointerstitial and glomerular fibrosis, myocardial fibrosis, arterial sclerosis, atherosclerosis, varicose veins, coronary infarcts, cerebral infarcts, myocardial fibrosis, musculoskeletal fibrosis, postsurgical adhesions, human kidney disease (e.g., nephritic syndrome, Alport's syndrome, HIV associated nephropathy, polycystic kidney disease, Fabry's disease, diabetic nephropathy, chronic glomerulonephritis, nephritis associated with systemic lupus, and the like), cutis keloid formation, progressive systemic sclerosis (PSS), primary sclerosing cholangitis (PSC), liver fibrosis, liver cirrhosis, renal fibrosis, pulmonary fibrosis, cystic fibrosis, chronic graft versus host disease, scleroderma (local and systemic), Grave's opthalmopathy, diabetic retinopathy, glaucoma, Peyronie's disease, penis fibrosis, urethrostenosis after a test using a cystoscope, inner accretion after surgery, scarring, myelofibrosis, idiopathic retroperitoneal fibrosis, peritoneal fibrosis from a known etiology, drug induced ergotism, fibrosis incident to benign or malignant cancer, fibrosis incident to microbial infection (e.g., viral, bacterial, parasitic, fungal, etc.), Alzheimer's disease, fibrosis incident to inflammatory bowel disease (including stricture formation in Crohn's disease and microscopic colitis), fibrosis induced by chemical or environmental insult (e.g., cancer chemotherapy, pesticides, radiation/cancer radiotherapy), and the like.
Diseases associated with fibrosis include lupus, graft versus host disease, scleroderma, systemic sclerosis, scleroderma-like disorders, sine scleroderma, calcinosis, Raynaud's esophageal dysfunction, sclerodactyly, telangiectasiae, hypersensitivity pneumonitis, collagen vascular disease, asthma, pulmonary arterial hypertension, glomerulonephritis, chronic obstructive pulmonary disease, fibrosis following myocardial infarction, central nervous system fibrosis following a stroke or neuro-degenerative diseases (e.g. Alzheimer's disease), proliferative vitreoretinopathy (PVR) and arthritis, silicosis, asbestos induced pulmonary fibrosis, acute lung injury and acute respiratory distress syndrome (including bacterial pneumonia induced, trauma induced, viral pneumonia induced, tuberculosis, ventilator induced, non-pulmonary sepsis induced, and aspiration induced).
Increased number of activated myofibroblasts in fibrotic diseases The emergence and disappearance of the myofibroblast appears to correlate with the initiation of active fibrosis and its resolution, respectively. In addition, the myofibroblast has many phenotypic features, which embody much of the pathologic alterations in fibrotic tissue, e.g. lung tissue. These features would seem to argue for an important role for the myofibroblast in the pathogenesis of fibrosis, e.g. lung fibrosis. Furthermore, the persistence of the myofibroblast may herald progressive disease, and, conversely, its disappearance may be an indicator of resolution. This in turn suggests that future therapeutic strategies targeting the myofibroblast would be productive.
Patients usually exhibit evidence of active fibrosis with increased numbers of activated fibroblasts, many of which have the phenotypic characteristics of myofibroblasts. At these sites, increased amounts of extracellular matrix deposition are evident with effacement of the normal alveolar architecture. Animal model studies show the myofibroblast to be the primary source of type I collagen gene expression in active fibrotic sites. In vitro studies show differentiation of these cells from fibroblasts under the influence of certain cytokines but indicate their susceptibility to nitric oxide mediated apoptosis. In addition to promoting myofibroblast differentiation, transforming growth factor-β1 (TGF-β1 ) provides protection against apoptosis. Thus, this well-known fibrogenic cytokine is important both for the emergence of the myofibroblast and its survival against apoptotic stimuli. This is consistent with the critical importance of this cytokine in diverse models of fibrosis in various tissues. In view of these properties, the persistence or prolonged survival of the myofibroblast may be the key to understanding why certain forms of lung injury may result in progressive disease, terminating in end stage disease.
Although pulmonary fibrosis has diverse etiologies, there is a common feature characteristic of this process, namely, the abnormal deposition of extracellular matrix that effaces the normal lung tissue architecture. A key cellular source of this matrix is the mesenchymal cell population that occupies much of the fibrotic lesion during the active period of fibrosis. This population is heterogeneous with respect to a number of key phenotypes. One of these phenotypes is the myofibroblast, which is commonly identified by its expression in α-smooth muscle actin and by features that are intermediate between the bona fide smooth muscle cell and the fibroblast. The de novo appearance of myofibroblasts at sites of wound healing and tissue repair/fibrosis is associated with the period of active fibrosis and is considered to be involved in wound contraction. Furthermore, the localization of myofibroblasts at sites undergoing active extracellular matrix deposition suggests an important role for these cells in the genesis of the fibrotic lesion. Increased TGF-βi family levels in fibrotic diseases
The transforming growth factor-βi (TGF-βi) family of proteins has the most potent stimulatory effect on extracellular matrix deposition of any cytokines so far examined. In animal models of pulmonary fibrosis enhanced TGF-P1 gene expression is temporally and spatially related to increased collagen gene expression and protein deposition. TGF-βi antibodies reduce collagen deposition in murine bleomycin- induced lung fibrosis and human fibrotic lung tissue shows enhanced TGF-βi gene and protein expression. Several lines of evidence suggest that TGF-β is a central regulator of pulmonary fibrosis. Several animal models over expressing TGF-β showed extensive progressive fibrosis but limited inflammation, indicating that TGF-β may play a predominant role in the progression of pulmonary fibrosis. Therapeutic efforts are therefore focusing on inhibition of TGF-β activity, for instance by anti-TGF- β1 -antibodies, or modulators of TGF-β1 such as pirfenidone. Pirfenidone inhibits TGF-β1 gene expression in vivo resulting in inhibition of TGF-β1 -mediated collagen synthesis and appears to slow progression of IPF in patients. Other novel, promising antifibrotic agents include relaxin (inhibits TGF-β-mediated overexpression of collagen and increases collagenases), suramin (inhibits growth factors), prostaglandin E2 (inhibits collagen production) and lovastatin (blocks formation of granulation tissue by induction of fibroblast apoptosis).
Diseases involving the lung associated with increased levels of TGF-β include chronic lung disease of prematurity, idiopathic pulmonary fibrosis, rapid progressive pulmonary fibrosis, giant-cell interstitial pneumonia, acute rejection after lung transplantation, cytomegalovirus pneumonitis after lung transplantation, bronchiolitis obliterans, asbestosis, coal worker's pneumoconiosis, silicosis, histiocytosis, sarcoidosis, eosinophilic granuloma, scleroderma, systemic lupus erythematosus, lymphangioleiomyomatosis, central fibrosis in pulmonary adenocarcinoma, cystic fibrosis, chronic obstructive lung disease, and asthma.
Increased TNF-α levels in fibrotic diseases
An important role of tumor necrosis factor-α (TNF-α) in interstitial fibrosis has been established using transgenic mice, which either overexpress or display a deficiency of this cytokine. Mice transgenically modified to overexpress TNF-α develop lung fibrosis. In contrast, mice null for TNF-α show marked resistance to bleomycin induced fibrosis. TNF-α can stimulate fibroblast replication and collagen synthesis in vitro, and pulmonary TNF-α gene expression rises after administration of bleomycin in mice. Soluble TNF-α receptors reduce lung fibrosis in murine models and pulmonary overexpression of TNF-α in transgenic mice is characterized by lung fibrosis. In patients with CFA or asbestosis, bronchoalveolar lavage fluid-derived macrophages release increased amounts of TNF-α compared with controls.
Increased TNF-α may induce fibrosis or fibrosis-associated conditions affecting any tissue including, for example, fibrosis of an internal organ, a cutaneous or dermal fibrosing disorder, and fibrotic conditions of the eye. Fibrosis of internal organs (e.g., liver, lung, kidney, heart blood vessels, gastrointestinal tract) occurs in disorders such as pulmonary fibrosis, idiopathic fibrosis, autoimmune fibrosis, myelofibrosis, liver cirrhosis, veno-occlusive disease, mesangial proliferative glomerulonephritis, crescentic glomerulonephritis, diabetic nephropathy, renal interstitial fibrosis, renal fibrosis in subjects receiving cyclosporin, allograft rejection, HTV associated nephropathy. Other fibrosis-associated disorders include systemic sclerosis, eosinophilia-myalgia syndrome, and fibrosis-associated CNS disorders such as intraocular fibrosis. Dermal fibrosing disorders include, for example, scleroderma, morphea, keloids, hypertrophic scars, familial cutaneous collagenoma, and connective tissue nevi of the collagen type. Fibrotic conditions of the eye include conditions such as diabetic retinopathy, post-surgical scarring (for example, after glaucoma filtering surgery and after crossed-eyes (strabismus) surgery), and proliferative vitreoretinopathy. Additional fibrotic conditions that may be treated by the methods of the present invention may result, for example, from rheumatoid arthritis, diseases associated with prolonged joint pain and deteriorated joints; progressive systemic sclerosis, polymyositis, dermatomyositis, eosinophilic fascitis, morphea, Raynaud's syndrome, and nasal polyposis.
Increased matrix metalloproteases levels in fibrotic diseases
The abnormal extracellular matrix (ECM) remodeling observed in the lungs of patients with interstitial pulmonary fibrosis (IPF) is due, at least in part, to an imbalance between matrix metalloproteases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs). Normal lung fibroblasts do not make MMP-9 in vitro, whereas fibroblasts from IPF lungs strongly express MMP-9. In addition, fibroblasts from patients with IPF express increased levels of all TIMPs. In this setting, TIMPs may play a role in apoptosis in some cell populations. In vitro studies of alveolar macrophages obtained from untreated patients with idiopathic pulmonary fibrosis showed marked increase in MMP-9 secretion compared to macrophages collected from healthy individuals. In animals models of bleomycin-induced pulmonary fibrosis MMPs have been shown to be elevated in bronchoalveolar lavage (BAL) fluid. Indeed, a synthetic inhibitor of MMP, Batimastat, has been shown to significantly reduce bleomycin-induced lung fibrosis, again pointing to the importance of MMPs in the development of this fibrotic disease in the lung. A number of studies have shown that the actions of MMPs can result in the release of growth factors and cytokines. These profibrotic factors require proteolytic processing for their activation or release from extracellular matrix or carrier proteins before they can exert their activity. In fact, the proteolytic activity processing of several key factors involved in the pathogenesis of pulmonary fibrosis such as insulin-like growth factor (IGF), TGF-βi and TNF-α occur through the actions of MMPs, thereby activating or releasing them from inhibitory protein-protein interactions. For example, IGFs in vivo are sequestered by six high affinity IGF binding proteins (IGFBPsI -6), preventing their ability to interact with IGF receptors. Studies examining adults and children IPF and interstitial lung disease show that beside IPF, IGFBP-3 and IFPB-2 levels are increased in IPF BAL fluid. MMPs have recently been shown to regulate the cleavage of IGF binding proteins, thereby liberating the complexed ligand to affect IGF actions in target cells. Observations have also shown that the gelatinases, MMP-9 and MMP-2 may be involved in proteolytic activation of latent TGF-β complexes. Furthermore, the MMP inhibitor Batimastat reduces MMP-9 activity in BAL fluid, which was associated with decreased amount of TGF-β and TNF-α.
Pulmonary fibrosis can be an all too common consequence of an acute inflammatory response of the lung to a host of inciting events. Chronic lung injury due to fibrotic changes can result from an identifiable inflammatory event or an insidious, unknown event. The inflammatory process can include infiltration of various inflammatory cell types, such as neutrophils and macrophages, the secretion of inflammatory cytokines and chemokines and the secretion of matrix remodeling proteinases.
Increased CCL18 levels in fibrotic diseases
The expression and regulation of cysteine-cysteine (CC) chemokine ligand 18 (CCL18), a marker of alternative activation, by human alveolar macrophages (AMs) is increased in patients with pulmonary fibrosis and correlates negatively with pulmonary function test parameters. Thus, CCL18 is an ideal diagnostic marker for pulmonary fibrosis.
The peptides of the present invention were tested using the assays described in Examples 14 - 15 for their effect as active therapeutic agents in the prophylaxis and/or treatment of fibrotic diseases and disorders.
Inflammatory disease
Inflammation is the final common pathway of various insults, such as infection, trauma, and allergies to the human body. It is characterized by the activation of the immune system with recruitment of inflammatory cells, production of pro- inflammatory cells and production of pro-inflammatory cytokines. Most inflammatory diseases and disorders are characterized by abnormal accumulation of inflammatory cells including monocytes/macrophages, granulocytes, plasma cells, lymphocytes and platelets. Along with tissue endothelial cells and fibroblasts, these inflammatory cells release a complex array of lipids, growth factors, cytokines and destructive enzymes that cause local tissue damage.
One form of inflammatory response is neutrophilic inflammation which is characterized by infiltration of the inflamed tissue by neutrophil polymorphonuclear leukocytes (PMN), which are a major component of the host defense. Tissue infection by extracellular bacteria represents the prototype of this inflammatory response. On the other hand, various non-infectious diseases are characterized by extravascular recruitment of neutrophils. This group of inflammatory diseases includes chronic obstructive pulmonary disease, adult respiratory distress syndrome, some types of immune-complex alveolitis, cystic fibrosis, bronchitis, bronchiectasis, emphysema, glomerulonephritis, rheumatoid arthritis, gouty arthritis, ulcerative colitis, certain dermatoses such as psoriasis and vasculitis. In these conditions neutrophils are thought to play a crucial role in the development of tissue injury which, when persistent, can lead to the irreversible destruction of the normal tissue architecture with consequent organ dysfunction. Tissue damage is primarily caused by the activation of neutrophils followed by their release of proteinases and increased production of oxygen species.
Chronic obstructive pulmonary disease (COPD) is described by the progressive development of airflow limitation that is not fully reversible. Most patients with COPD have three pathological conditions; bronchitis, emphysema and mucus plugging. This disease is characterized by a slowly progressive and irreversible decrease in forced expiratory volume in the first second of expiration (FEVi), with relative preservation of forced vital capacity (FVC). In both asthma and COPD there is significant, but distinct, remodeling of airways. Most of the airflow obstruction is due to two major components, alveolar destruction (emphysema) and small airways obstruction (chronic obstructive bronchitis). COPD is mainly characterized by profound mucus cell hyperplasia. Neutrophil infiltration of the patient's lungs is a primary characteristic of COPD. Elevated levels of proinflammatory cytokines, like TNF-α, and especially chemokines like interleukin-8 (IL-8) and growth-regulated oncogene-α (GRO-α) play a very important role in pathogenesis of this disease. Platelet thromboxane synthesis is also enhanced in patients with COPD. Most of the tissue damage is caused by activation of neutrophils followed by their release of metalloproteinases, and increased production of oxygen species. TNF-α has several biologic activities that are important in homeostasis as well as in pathophysiological conditions. The main sources of TNF-α are monocytes- macrophages, T-lymphocytes and mast cells. The finding that anti-TNF-α antibodies (cA2) are effective in the treatment of patients suffering from rheumatoid arthritis (RA) intensified the interest to find new TNF-α inhibitors as possible potent medicaments for RA. Rheumatoid arthritis is an autoimmune chronic inflammatory disease characterized by irreversible pathological changes of the joints. In addition to RA, TNF-α antagonists are also applicable to several other pathological conditions and diseases such as spondylitis, osteoarthritis, gout and other arthritic conditions, sepsis, septic shock, toxic shock syndrome, atopic dermatitis, contact dermatitis, psoriasis, glomerulonephritis, lupus erythematosus, scleroderma, asthma, cachexia, chronic obstructive lung disease, congestive heart failure, insulin resistance, lung (pulmonary) fibrosis, multiple sclerosis, Crohn's disease, ulcerative colitis, viral infections and AIDS.
The term "immunoinflammatory disorder" encompasses a variety of conditions, including autoimmune diseases, proliferative skin diseases, and inflammatory dermatoses.

By "dermal inflammatory disorders" or "inflammatory dermatoses" is meant an inflammatory disorder selected from psoriasis, guttate psoriasis, inverse psoriasis, pustular psoriasis, erythrodermic psoriasis, acute febrile neutrophilic dermatosis, eczema, asteatotic eczema, dyshidrotic eczema, vesicular palmoplanar eczema, acne vulgaris, atopic dermatitis, contact dermatitis, allergic contact dermatitis, dermatomyositis, exfoliative dermatitis, hand eczema, pompholyx, rosacea, rosacea caused by sarcoidosis, rosacea caused by scleroderma, rosacea caused by Sweet's syndrome, rosacea caused by systemic lupus erythematosus, rosacea caused by urticaria, rosacea caused by zoster-associated pain, Sweet's disease, neutrophilic hidradenitis, sterile pustulosis, drug eruptions, seborrheic dermatitis, pityriasis rosea, cutaneous kikuchi disease, pruritic urticarial papules and plaques of pregnancy, Stevens-Johnson syndrome and toxic epidermal necrolysis, tattoo reactions, Wells syndrome (eosinophilic cellulitis), reactive arthritis (Reiter"s syndrome), bowel-associated dermatosis-arthritis syndrome, rheumatoid neutrophilic dermatosis, neutrophilic eccrine hidradenitis, neutrophilic dermatosis of the dorsal hands, balanitis circumscripta plasmacellularis, balanoposthitis, Behcet's disease, erythema annulare centrifugum, erythema dyschromicum perstans, erythema multiforme, granuloma annulare, hand dermatitis, lichen nitidus, lichen planus, lichen sclerosus et atrophicus, lichen simplex chronicus, lichen spinulosus, nummular dermatitis, pyoderma gangrenosum, sarcoidosis, subcorneal pustular dermatosis, urticaria, and transient acantholytic dermatosis.

As will be appreciated by one skilled in the art, a particular disease, disorder, or condition may be characterized as being both a proliferative skin disease and an inflammatory dermatosis. An example of such a disease is psoriasis.

A human peptide is "active" in an inflammatory disease if the inhibition is > 50% in one of the assays described below. Inhibition (as percentage) was calculated using the following formula: % inhibition = (1 - concentration of cytokines in sample/concentration of cytokines in positive control) x 100. The positive control refers to stimulated samples, not treated with substances.
Th1/Th2 cytokine profiles
T lymphocytes are a major source of cytokines. These cells bear antigen specific receptors on their cell surface to allow recognition of foreign pathogens. They can also recognize normal tissue during episodes of autoimmune diseases. There are two main subsets of T lymphocytes, distinguished by the presence of cell surface molecules known as CD4 and CD8. T lymphocytes expressing CD4 are also known as helper T cells, and these are regarded as being the most prolific cytokine producers. This subset can be further subdivided into Th1 and Th2, and the cytokines they produce are known as Th1-type cytokines and Th2-type cytokines.
Th 1 -type cytokines tend to produce the pro-inflammatory responses responsible for killing intracellular parasites and for perpetuating autoimmune responses. Interferon gamma is the main Th1 cytokine. Excessive pro-inflammatory responses can lead to uncontrolled tissue damage, so there needs to be a mechanism to counteract this. The Th2-type cytokines include lnterleukin 4, lnterleukin 5, and lnterleukin 13, which are associated with the promotion of IgE and eosinophilic responses in atopy, and also lnterleukin-10, which has more of an anti-inflammatory response. In excess, Th2 responses will counteract the Th1 mediated microbicidal action. The optimal scenario would therefore seem to be that humans should produce a well balanced Th1 and Th2 response, suited to the immune challenge.
Allergy is regarded as a Th2 weighted imbalance. Pregnancy and early postnatal life are also viewed as Th2 phenomena (to reduce the risk of miscarriage, a strong Th2 response is necessary to modify the Th1 cellular response in utero). The fetus can switch on an immune response early in pregnancy, and because pregnancy is chiefly a Th2 situation, babies tend to be born with Th2 biased immune responses. These can be switched off rapidly postnatally under the influence of microbiological exposure or can be enhanced by early exposure to allergens.
Th1 cells produce interferon-gamma, lnterleukin 2, and tumor necrosis factor-beta, which activate macrophages and are responsible for cell-mediated immunity and phagocyte-dependent protective responses. By contrast, Th2 cells produce cytokines which are responsible for strong antibody production, eosinophil activation, and inhibition of several macrophage functions, thus providing phagocyte-independent protective responses. Th1 cells mainly develop following infections by intracellular bacteria and some viruses, whereas Th2 cells predominate in response to infestations by gastrointestinal nematodes. Polarized Th1 and Th2 cells not only exhibit different functional properties, but also show the preferential expression of some activation markers and distinct transcription factors. Several mechanisms may influence the Th cell differentiation, which include the cytokine profile of "natural immunity" evoked by different offending agents, the nature of the peptide ligand, as well as the activity of some costimulatory molecules and microenvironmentally secreted hormones, in the context of the individual genetic background. In addition to playing different roles in protection, polarized Th1-type and Th2-type responses are also responsible for different types of immunopathological reactions. Th1 cells are involved in the pathogenesis of organ-specific autoimmune disorders like Crohn's disease is one, Helicobacter pylori-induced peptic ulcer, acute kidney allograft rejection, unexplained recurrent abortions, tuberculosis, myocarditis, multiple sclerosis, scleroderma, Type 1 diabetes, rheumatoid arthritis (RA), sarcoidosis, autoimmune thyroiditis and uveitis. In contrast, allergen-specific Th2 responses are responsible for atopic disorders in genetically susceptible individuals like asthma. Moreover, Th2 responses against still unknown antigens predominate in Omenn's syndrome, idiopathic pulmonary fibrosis, and progressive systemic sclerosis. Finally, the prevalence of Th2 responses may play some role in a more rapid evolution of human immunodeficiency virus infection to the full-blown disease.
It is object of current application to find peptides which produce a well balanced Th1 and Th2 response in situations of Th1 predominance, in the situation of Th2 predominance, or even at situations where both, Th1 and Th2 cells are too much activated, as exemplified after severe infections.

Neurodegenerative disease
The present invention also relates generally to the fields of neurology and psychiatry and to methods of protecting the cells of a mammalian central nervous system from damage or injury.
Injuries or trauma of various kinds to the central nervous system (CNS) or the peripheral nervous system (PNS) can produce profound and long-lasting neurological and/or psychiatric symptoms and disorders. One form that this can take is the progressive death of neurons or other cells of the central nervous system (CNS), i.e., neurodegeneration or neuronal degeneration.
Neuronal degeneration as a result of, for example; Alzheimer's disease, multiple sclerosis, cerebral-vascular accidents (CVAs)/stroke, traumatic brain injury, spinal cord injuries, degeneration of the optic nerve, e.g., ischemic optic neuropathy or retinal degeneration and other central nervous system disorders is an enormous medical and public health problem by virtue of both its high incidence and the frequency of long-term sequelae. Animal studies and clinical trials have shown that amino acid transmitters (especially glutamate), oxidative stress and inflammatory reactions contribute strongly to cell death in these conditions. Upon injury or upon ischemic insult, damaged neurons release massive amounts of the neurotransmitter glutamate, which is excitotoxic to the surrounding neurons. Glutamate is a negatively charged amino acid that is an excitatory synaptic transmitter in the mammalian nervous system. Although the concentration of glutamate can reach the millimolar range in nerve terminals its extracellular concentration is maintained at a low level to prevent neurotoxicity. It has been noted that glutamate can be toxic to neurons if presented at a high concentration. The term "excitotoxicity" has been used to describe the cytotoxic effect that glutamate (and other such excitatory amino acids) can have on neurons when applied at high dosages.
Patients with injury or damage of any kind to the central (CNS) or peripheral (PNS) nervous system including the retina may benefit from neuroprotective methods. This nervous system injury may take the form of an abrupt insult or an acute injury to the nervous system as in, for example, acute neurodegenerative disorders including, but not limited to; acute injury, hypoxia-ischemia or the combination thereof resulting in neuronal cell death or compromise. Acute injury includes, but is not limited to, traumatic brain injury (TBI) including, closed, blunt or penetrating brain trauma, focal brain trauma, diffuse brain damage, spinal cord injury, intracranial or intravertebral lesions (including, but not limited to, contusion, penetration, shear, compression or laceration lesions of the spinal cord or whiplash shaken infant syndrome).
In addition, deprivation of oxygen or blood supply in general can cause acute injury as in hypoxia and/or ischemia including, but not limited to, cerebrovascular insufficiency, cerebral ischemia or cerebral infarction (including cerebral ischemia or infarctions originating from embolic occlusion and thrombosis, retinal ischemia (diabetic or otherwise), glaucoma, retinal degeneration, multiple sclerosis, toxic and ischemic optic neuropathy, reperfusion following acute ischemia, perinatal hypoxic- ischemic injury, cardiac arrest or intracranial hemorrhage of any type (including, but not limited to, epidural, subdural, subarachnoid or intracerebral hemorrhage).
Trauma or injury to tissues of the nervous system may also take the form of more chronic and progressive neurodegenerative disorders, such as those associated with progressive neuronal cell death or compromise over a period of time including, but not limited to, Alzheimer's disease, Pick's disease, diffuse Lewy body disease, progressive supranuclear palsy (Steel-Richardson syndrome), multisystem degeneration (Shy-Drager syndrome), chronic epileptic conditions associated with neurodegeneration, motor neuron diseases (amyotrophic lateral sclerosis), multiple sclerosis, degenerative ataxias, cortical basal degeneration, ALS-Parkinson's- dementia complex of Guam, subacute sclerosing panencephalitis, Huntington's disease, Parkinson's disease, synucleinopathies (including multiple system atrophy), primary progressive aphasia, striatonigral degeneration, Machado-Joseph disease or spinocerebellar ataxia type 3 and olivopontocerebellar degenerations, bulbar and pseudobulbar palsy, spinal and spinobulbar muscular atrophy (Kennedy's disease), primary lateral sclerosis, familial spastic paraplegia, Werdnig-Hoffmann disease, Kugelberg-Welander disease, Tay-Sach's disease, Sandhoff disease, familial spastic disease, Wohlfart-Kugelberg-Welander disease, spastic paraparesis, progressive multifocal leukoencephalopathy, familial dysautonomia (Riley-Day syndrome) or prion diseases (including, but not limited to Creutzfeld-Jakob disease, Gerstmann- Strussler-Scheinker disease, Kuru disease or fatal familial insomnia).
In addition, trauma and progressive injury to the nervous system can take place in various psychiatric disorders, including but not limited to, progressive, deteriorating forms of bipolar disorder or schizoaffective disorder or schizophrenia, impulse control disorders, obsessive compulsive disorder (OCD), behavioral changes in temporal lobe epilepsy and personality disorders.
In one preferred embodiment the compounds of the invention would be used to provide neuroprotection in disorders involving trauma and progressive injury to the nervous system in various psychiatric disorders.

The term "neuroprotection" as used herein shall mean; inhibiting, preventing, ameliorating or reducing the severity of the dysfunction, degeneration or death of nerve cells, axons or their supporting cells in the central or peripheral nervous system of a mammal, including a human. This includes the treatment or prophylaxis of a neurodegenerative disease; protection against excitotoxicity or ameliorating the cytotoxic effect of a compound (for example, a excitatory amino acid such as glutamate; a toxin; or a prophylactic or therapeutic compound that exerts an immediate or delayed cytotoxic side effect including but not limited to the immediate or delayed induction of apoptosis) in a patient in need thereof.
The term "a patient in need of treatment with a neuroprotective drug " as used herein will refer to any patient who currently has or may develop any of the above syndromes or disorders, or any disorder in which the patient's present clinical condition or prognosis could benefit from providing neuroprotection to prevent the development, extension, worsening or increased resistance to treatment of any neurological or psychiatric disorder.
The term "treating" or "treatment" as used herein, refers to any indicia of success in the prevention or amelioration of an injury, pathology or condition, including any objective or subjective parameter such as abatement; remission; diminishing of symptoms or making the injury, pathology, or condition more tolerable to the patient; slowing in the rate of degeneration or decline; making the final point of degeneration less debilitating; or improving a subject's physical or mental well-being. The treatment or amelioration of symptoms can be based on objective or subjective parameters; including the results of a physical examination, neurological examination, and/or psychiatric evaluations. In some embodiments this invention provides methods of neuroprotection. In certain embodiments, these methods comprise administering a therapeutically effective amount of the peptide combination of the invention to a patient who has not yet developed overt, clinical signs or symptoms of injury or damage to the cells of the nervous system but who may be in a high risk group for the development of neuronal damage because of injury or trauma to the nervous system or because of some known predisposition either biochemical or genetic or the finding of a verified biomarker of one or more of these disorders.
Thus, in some embodiments, the methods and compositions of the present invention are directed toward neuroprotection in a subject who is at risk of developing neuronal damage but who has not yet developed clinical evidence. This patient may simply be at "greater risk" as determined by the recognition of any factor in a subject's, or their families, medical history, physical exam or testing that is indicative of a greater than average risk for developing neuronal damage. Therefore, this determination that a patient may be at a "greater risk" by any available means can be used to determine whether the patient should be treated with the methods of the present invention.
Accordingly, in an exemplary embodiment, subjects who may benefit from treatment by the methods and peptides of this invention can be identified using accepted screening methods to determine risk factors for neuronal damage. These screening methods include, for example, conventional work-ups to determine risk factors including but not limited to: for example, head trauma, either closed or penetrating, CNS infections, bacterial or viral, cerebrovascular disease including but not limited to stroke, brain tumors, brain edema, cysticercosis, porphyria, metabolic encephalopathy, drug withdrawal including but not limited to sedative-hypnotic or alcohol withdrawal, abnormal perinatal history including anoxia at birth or birth injury of any kind, cerebral palsy, learning disabilities, hyperactivity, history of febrile convulsions as a child, history of status epilepticus, family history of epilepsy or any seizure related disorder, inflammatory disease of the brain including lupis, drug intoxication either direct or by placental transfer, including but not limited to cocaine poisoning, parental consanguinity, and treatment with medications that are toxic to the nervous system including psychotropic medications.
The determination of which patients may benefit from treatment with a neuroprotective drug in patients who have no clinical signs or symptoms may be based on a variety of "surrogate markers" or "biomarkers". As used herein, the terms "surrogate marker" and "biomarker" are used interchangeably and refer to any anatomical, biochemical, structural, electrical, genetic or chemical indicator or marker that can be reliably correlated with the present existence or future development of neuronal damage. In some instances, brain-imaging techniques, such as computer tomography (CT), magnetic resonance imaging (MRI) or positron emission tomography (PET), can be used to determine whether a subject is at risk for neuronal damage. Suitable biomarkers for the methods of this invention include, but are not limited to: the determination by MRI1 CT or other imaging techniques, of sclerosis, atrophy or volume loss in the hippocampus or overt mesial temporal sclerosis (MTS) or similar relevant anatomical pathology; the detection in the patient's blood, serum or tissues of a molecular species such as a protein or other biochemical biomarker, e.g., elevated levels of ciliary neurotrophic factor (CNTF) or elevated serum levels of a neuronal degradation product; or other evidence from surrogate markers or biomarkers that the patient is in need of treatment with a neuroprotective drug.
It is expected that many more such biomarkers utilizing a wide variety of detection techniques will be developed in the future. It is intended that any such marker or indicator of the existence or possible future development of neuronal damage, as the latter term is used herein, may be used in the methods of this invention for determining the need for treatment with the compounds and methods of this invention.
A determination that a subject has, or may be at risk for developing, neuronal damage would also include, for example, a medical evaluation that includes a thorough history, a physical examination, and a series of relevant bloods tests. It can also include an electroencephalogram (EEG), CT, MRI or PET scan. A determination of an increased risk of developing neuronal damage or injury may also be made by means of genetic testing, including gene expression profiling or proteomic techniques. For psychiatric disorders that may be stabilized or improved by a neuroprotective drug, e.g., bipolar disorder, schizoaffective disorder, schizophrenia, impulse control disorders, etc. the above tests may also include a present state exam and a detailed history of the course of the patients symptoms such as mood disorder symptoms and psychotic symptoms over time and in relation to other treatments the patient may have received over time, e.g., a life chart. These and other specialized and routine methods allow the clinician to select patients in need of therapy using the methods and formulations of this invention. In some embodiments of the present invention peptides suitable for use in the practice of this invention will be administered either singly or concomitantly with at least one or more other compounds or therapeutic agents, e.g., with other neuroprotective drugs or antiepileptic drugs, anticonvulsant drugs. In these embodiments, the present invention provides methods to treat or prevent neuronal injury in a patient. The method includes the step of; administering to a patient in need of treatment, an effective amount of one of the peptides disclosed herein in combination with an effective amount of one or more other compounds or therapeutic agents that have the ability to provide neuroprotection or to treat or prevent seizures or epileptogenesis or the ability to augment the neuroprotective effects of the compounds of the invention.
As used herein the term "combination administration" of a compound, therapeutic agent or known drug with the peptide combination of the present invention means administration of the drug and the one or more compounds at such time that both the known drug and the peptide combination will have a therapeutic effect. In some cases this therapeutic effect will be synergistic. Such concomitant administration can involve concurrent (i.e. at the same time), prior, or subsequent administration of the drug with respect to the administration of the peptide combination of the present invention. A person of ordinary skill in the art would have no difficulty determining the appropriate timing, sequence and dosages of administration for particular drugs and peptides of the present invention.
The said one or more other compounds or therapeutic agents may be selected from compounds that have one or more of the following properties: antioxidant activity; NMDA receptor antagonist activity, augmentation of endogenous GABA inhibition; NO synthase inhibitor activity; iron binding ability, e.g., an iron chelator; calcium binding ability, e.g., a Ca (II) chelator; zinc binding ability, e.g., a Zn (II) chelator; the ability to effectively block sodium or calcium ion channels, or to open potassium or chloride ion channels in the CNS of a patient.
The peptides of the present invention were tested using the assays described in Examples 1-7, 9-17 for their effect as active therapeutic agents in the prophylaxis and/or treatment of neurodegenerative diseases and disorders.
Heart and vascular disease Heart disease is a general term used to describe many different heart conditions. For example, coronary artery disease, which is the most common heart disease, is characterized by constriction or narrowing of the arteries supplying the heart with oxygen-rich blood, and can lead to myocardial infarction, which is the death of a portion of the heart muscle. Heart failure is a condition resulting from the inability of the heart to pump an adequate amount of blood through the body. Heart failure is not a sudden, abrupt stop of heart activity but, rather, typically develops slowly over many years, as the heart gradually loses its ability to pump blood efficiently. Risk factors for heart failure include coronary artery disease, hypertension, valvular heart disease, cardiomyopathy, disease of the heart muscle, obesity, diabetes, and/or a family history of heart failure.
Examples of cardiovascular diseases and disorders are: aneurysm, stable angina, unstable angina, angina pectoris, angioneurotic edema, aortic valve stenosis, aortic aneurysm, arrhythmia, arrhythmogenic right ventricular dysplasia, arteriosclerosis, arteriovenous malformations, atrial fibrillation, Behcet syndrome, bradycardia, cardiac tamponade, cardiomegaly, congestive cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, carotid stenosis, cerebral hemorrhage, Churg-Strauss syndrome, diabetes, Ebstein's Anomaly, Eisenmenger complex, cholesterol embolism, bacterial endocarditis, fibromuscular dysplasia, congenital heart defects, heart diseases, congestive heart failure, heart valve diseases, heart attack, epidural hematoma, hematoma, subdural, Hippel-Lindau disease, hyperemia, hypertension, pulmonary hypertension, cardiac hypertrophy, left ventricular hypertrophy, right ventricular hypertrophy, hypoplastic left heart syndrome, hypotension, intermittent claudication, ischemic heart disease, Klippel-Trenaunay- Weber syndrome, lateral medullary syndrome, long QT syndrome mitral valve prolapse, moyamoya disease, mucocutaneous lymph node syndrome, myocardial infarction, myocardial ischemia, myocarditis, pericarditis, peripheral vascular diseases, phlebitis, polyarteritis nodosa, pulmonary atresia, Raynaud disease, Sneddon syndrome, superior vena cava syndrome, syndrome X, tachycardia, Takayasu's arteritis, hereditary hemorrhagic telangiectasia, telangiectasis, temporal arteritis, tetralogy of Fallot, thromboangiitis obliterans, thrombosis, thromboembolism, tricuspid atresia, varicose veins, vascular diseases, vasculitis, vasospasm, ventricular fibrillation, Williams syndrome, peripheral vascular disease, varicose veins and leg ulcers, deep vein thrombosis, Wolff-Parkinson-White syndrome.
Vascular diseases are often the result of decreased perfusion in the vascular system or physical or biochemical injury to the blood vessel.
Peripheral vascular disease (PVD) is defined as a disease of blood vessels often encountered as narrowing of the vessels of the limbs. There are two main types of these disorders, functional disease which doesn't involve defects in the blood vessels but rather arises from stimuli such as cold, stress, or smoking, and organic disease which arises from structural defects in the vasculature such as atherosclerotic lesions, local inflammation, or traumatic injury. This can lead to occlusion of the vessel, aberrant blood flow, and ultimately to tissue ischemia.
One of the more clinically significant forms of PVD is peripheral artery disease (PAD). PAD is often treated by angioplasty and implantation of a stent or by artery bypass surgery. Clinical presentation depends on the location of the occluded vessel. For example, narrowing of the artery that supplies blood to the intestine can result in severe postprandial pain in the lower abdomen resulting from the inability of the occluded vessel to meet the increased oxygen demand arising from digestive and absorptive processes. In severe forms the ischemia can lead to intestinal necrosis. Similarly, PAD in the leg can lead to intermittent pain, usually in the calf, that comes and goes with activity. This disorder is known as intermittent claudication (IC) and can progress to persistent pain while resting, ischemic ulceration, and even amputation.
Peripheral vascular disease is also manifested in atherosclerotic stenosis of the renal artery, which can lead to renal ischemia and kidney dysfunction.
One disease in which vascular diseases and their complications are very common is diabetes mellitus. Diabetes mellitus causes a variety of physiological and anatomical irregularities, the most prominent of which is the inability of the body to utilize glucose normally, which results in hyperglycemia. Chronic diabetes can lead to complications of the vascular system which include atherosclerosis, abnormalities involving large and medium size blood vessels (macroangiopathy) and abnormalities involving small blood vessels (microangiopathy) such as arterioles and capillaries.
Patients with diabetes mellitus are at increased risk of developing one or more foot ulcers as a result of established long-term complications of the disease, which include impaired nerve function (neuropathy) and/or ischemia. Local tissue ischemia is a key contributing factor to diabetic foot ulceration.
In addition to large vessel disease, patients with diabetes suffer further threat to their skin perfusion in at least two additional ways. First, by involvement of the non- conduit arteries, which are detrimentally affected by the process of atherosclerosis, and secondly, and perhaps more importantly, by impairment of the microcirculatory control mechanisms (small vessel disease). Normally, when a body part suffers some form of trauma, the body part will, as part of the body's healing mechanism, experience an increased blood flow. When small vessel disease and ischemia are both present, as in the case of many diabetics, this natural increased blood flow response is significantly reduced. This fact, together with the tendency of diabetics to form blood clots (thrombosis) in the microcirculatory system during low levels of blood flow, is believed to be an important factor in ulcer pathogenesis.
Neuropathy is a general term which describes a disease process which leads to the dysfunction of the nervous system, and is one of the major complications of diabetes mellitus, with no well-established therapies for either its symptomatic treatment or for prevention of progressive decline in nerve function.
The thickening and leakage of capillaries caused by diabetes primarily affect the eyes (retinopathy) and kidneys (nephropathy). The thickening and leakage of capillaries caused by diabetes are also associated with skin disorders and disorders of the nervous system (neuropathy).
The eye diseases associated with diabetes are nonproliferative diabetic retinopathy, proliferative diabetic retinopathy, diabetic maculopathy, glaucoma, cataracts and the like.
Other diseases, although not known to be related to diabetes are similar in their physiological effects on the peripheral vascular system. Such diseases include Raynaud syndrome, CREST syndrome, autoimmune diseases such as erythematosis, rheumatoid disease, and the like.
As used herein, the term "peripheral vascular diseases" comprises any peripheral vascular disease including peripheral and autonomic neuropathies. Examples of "peripheral vascular disease" include peripheral arterial disease, such as chronic arterial occlusion including arteriosclerosis, arteriosclerosis obliterans and thromboangiitis obliterans (Buerger's disease), macroangiopathy, microangiopathy, diabetes mellitus, thrombophlebitis, phlebemphraxis, Raynaud's disease, Raynaud's syndrome, CREST syndrome, health hazard due to vibration, Sudeck's syndrome, intermittent claudication, cold sense in extremities, abnormal sensation in extremities, sensitivity to the cold, Meniere's disease, Meniere's syndrome, numbness, lack of sensation, anesthesia, resting pain, causalgia (burning pain), disturbance of peripheral circulation function, disturbance of nerve function, disturbance of motor function, motor paralysis, diabetic peripheral circulation disorder, lumbar spinal canal stenosis, diabetic neuropathy, shock, autoimmune disease such as erythematosis, rheumatoid disease and rheumatoid arthritis, autonomic neuropathy, diabetic autonomic neuropathy, autonomic imbalance, orthostatic hypotension, erectile dysfunction, female sexual dysfunction, retrograde ejaculation, cystopathy, neurogenic bladder, defective vaginal lubrication, exercise intolerance, cardiac denervation, heat intolerance, gustatory sweating, diabetic complication, hyperglycemia, hypoglycemia unawareness, hypoglycemia unresponsiveness; glaucoma, neovascular glaucoma, cataract, retinopathy, diabetic retinopathy, diabetic maculopathy, occlusion of retinal artery, obstruction of central artery of retina, occlusion of retinal vein, macular edema, aged macular degeneration, aged disciform macular degeneration, cystoid macular edema, palpebral edema, retinal edema, chorioretinopathy, neovascular maculopathy, uveitis, iritis, retinal vasculitis, endophthalmitis, panophthalmitis, metastatic ophthalmia, choroiditis, retinal pigment epithelitis, conjunctivitis, cyclitis, scleritis, episcleritis, optic neuritis, retrobulbar optic neuritis, keratitis, blepharitis, exudative retinal detachment, corneal ulcer, conjunctival ulcer, chronic nummular keratitis, Thygeson keratitis, progressive Mooren' s ulcer, damage of skin, skin ulcer including foot ulcer, diabetic ulcer, burn ulcer, lower leg ulcer, postoperative ulcer, traumatic ulcer, ulcer after herpes zoster, radiation ulcer, drug induced ulcer, frostbite (cold injury) , chilblain, gangrene and sudden gangrene, angina pectoris/ variant angiitis, coronary arteriosclerosis (chronic ischemic heart disease, asymptomatic ischemic heart disease, arteriosclerotic cardiovascular disease), myocardial infarction, heart failure, congestive heart failure and painless ischemic heart disease, pulmonary edema, hypertension, pulmonary hypertension; portal hypertension, diabetic nephropathy, decubitus, renal failure.
The peptides of the present invention were tested using the assays described in Examples 1-7, 9-17 for their effect as active therapeutic agents in the prophylaxis and/or treatment of heart and vascular diseases and disorders.
Angiogenesis
Angiogenesis is a physiological process involving the growth of new blood vessels from pre-existing vessels. Angiogenesis is a normal process in growth and development, as well as in wound healing. However, this is also a fundamental step in the transition of tumors from a dormant state to a malignant state.
Angiogenesis occurs in several well-characterized stages. First, biological signals known as angiogenic growth factors activate receptors present on endothelial cells present in pre-existing blood vessels. Second, the activated endothelial cells begin to release enzymes called proteases that degrade the basement membrane in order to allow endothelial cells to escape from the original (parent) vessel walls. The endothelial cells then proliferate into the surrounding matrix and form solid sprouts connecting neighboring vessels. As sprouts extend toward the source of the angiogenic stimulus, endothelial cells migrate, using adhesion molecules, called integrins. These sprouts then form loops to become a full-fledged vessel lumen as cells migrate to the site of angiogenesis. Sprouting occurs at a rate of several millimeters per day, and enables new vessels to grow across gaps in the vasculature.
Therapeutic angiogenesis is the application of specific compounds which may inhibit or induce the creation of new blood vessels in the body in order to combat disease. The presence of blood vessels where there should be none may affect the mechanical properties of a tissue, increasing the likelihood of failure. The absence of blood vessels in a repairing or otherwise metabolically active tissue may retard repair or some other function. Several diseases are the result of failure or insufficient blood vessel formation and may be treated by a local expansion of blood vessels, thus bringing new nutrients to the site, facilitating repair. Other diseases may be created by a local expansion of blood vessels, interfering with normal physiological processes.
Angiogenesis represents an excellent therapeutic target for the treatment of, for example, cardiovascular diseases. It is a potent, physiological process that underlies the natural manner in which the human body responds to a diminution of blood supply to vital organs, namely the production of new collateral vessels to overcome the ischemic insult.
The modern clinical application of the principle "angiogenesis" can be divided into two main areas:
1. Anti-angiogenic therapies
2. Pro-angiogenic therapies.
Whereas anti-angiogenic therapies are trying to fight: • Any type of cancer and malignancies and their metastases in numerous organs, like hemangiomas (because tumors, in general, are nutrition- and oxygen-dependent, thus being in need of adequate blood supply),
• Infectious diseases,
• Vasculitis and excessive angiogenesis in autoimmune disorders such as systemic sclerosis (Scleroderma), multiple sclerosis, Sjogren's disease,
• Vascular malformations in blood and lymph vessels like DiGeorge syndrome, hereditary haemorrhagic telangiectasia, cavernous hemangioma, cutaneous hemangioma, lymphatic malformations, transplant arteriopathy, atherosclerosis, vascular anastomoses, • Adipose tissue in obesity,
• Chronic allograft rejections,
• Skin diseases like psoriasis, warts, allergic dermatitis, scar keloids, pyogenic granulomas, blistering disease, Kaposi sarcoma in AIDS patients, systemic sclerosis (Scleroderma),
• Eye diseases like persistent hyperplastic vitreous syndrome, diabetic retinopathy, retinopathy of prematurity, choroidal neovascularization,
• Lung diseases like any type of pulmonary hypertension, asthma, nasal polyps, rhinitis, chronic airway inflammation and obstruction (COPD), cystic fibrosis, acute lung injury, bronchiolitis obliterans organizing pneumonia,
• Gastrointestinal tract diseases like inflammatory bowel disease, periodontal disease, ascites, peritoneal adhesions, liver cirrhoses,
• Reproductive system diseases like endometriosis, uterine bleeding, ovarian cysts, ovarian hyperstimulation, • Bone and joint diseases like arthritis and synovitis, osteomyelitis, osteophyte formation, HIV-induced bone marrow angiogenesis,
• Kidney diseases like early diabetic nephropathy
The pro-angiogenic therapies are important in the search of new treatment options for diseases characterized or caused by insufficient angiogenesis or vessel regression:
• Nervous system diseases like Alzheimer's disease, amyotrophic lateral sclerosis, diabetic neuropathy, stroke,
• Blood and lymph vessels diseases like diabetic angiopathy, impared reendothelialization in restenosis, lymphedema,
• Gastrointestinal ulcerations, oral ulcers, mucosal ischemia in Crohn's disease
• Skin diseases like lupus,
• Reproductive system diseases like preeclampsia, menorrhagia, • Lung diseases like neonatal respiratory distress syndrome, pulmonary fibrosis, emphysema,
• Kidney diseases like nephropathy, glomerulosclerosis, tubulointerstitial fibrosis,
• Bone diseases like osteoporosis, impaired bone fracture healing, • Heart diseases like ischaemic heart disease, cardiac failure,
• Any type of wound healing disorders.
Angiogenesis research is also a cutting edge field in cancer research, and traditional therapies, such as radiation therapy, may work in part by targeting the genomically stable endothelial cell compartment, rather than the genomically unstable tumor cell compartment. New blood vessel formation is a relatively fragile process, subject to disruptive interference at several levels. In short, the therapy is the selection agent which is being used to kill a cell compartment. Tumor cells evolve resistance rapidly due to rapid generation time (days) and genomic instability (variation), whereas endothelial cells are a good target because of a long generation time (months) and genomic stability (low variation).
Angiogenesis-based tumour therapy relies on natural and synthetic angiogenesis inhibitors like angiostatin, endostatin and tumstatin. These are proteins that mainly originate as specific fragments pre-existing structural proteins like collagen or plasminogen.
Recently, the 1 st FDA-approved therapy targeted at angiogenesis in cancer came on the market in the US. This is a monoclonal antibody directed against an isoform of VEGF, and the therapy has been approved for use in colorectal cancer in combination with established chemotherapy. Therefore there is a wide medical need for additional medicaments in the field of angiogenesis.
In addition, in terms of tissue engineering, medicaments that influence angiogenesis in vascular grafts are needed. More than 450,000 vascular grafts were used in coronary bypass surgeries annually. Other uses for vascular grafts include treatments for blood vessel aneurysms and fistulas, as well as replacements for diseased arteries in other locations in the body. When possible, the best choice for a replacement vessel is an autograft, where sections of the patient's healthy blood vessels (usually veins) are harvested and implanted in the required location. Many patients, however, especially those with pre-existing vascular disease or patients that have already had autograft procedures, do not have blood vessels that are healthy enough to adequately serve as replacements. In these cases, the most common form of treatment has been the use of synthetic polymeric materials, like ePTFE (extended polytetrafluoroethylene) and Dacron (poly[ethylene terephthalate]), to form either permanent or resorbable replacements for the damaged vessels. In cases where the graft can be of a large diameter (greater than 5-6 mm), the synthetic material has been effective. However, in situations where a smaller vessel diameter is required, the synthetic materials cannot be used due to high rates of stenosis and thrombus formation. One possible solution is to use natural materials like collagen, either modified or combined with a synthetic material, to form a graft that more closely mimics the body's natural function and has low thrombogenicity and low incidence of stenosis. Failure of the autograft is usually due to some form of occlusion that results from lumenal narrowing. Damage of the vessel during removal and reimplantation may cause the recruitment of factors or cells that adhere to the autograft wall and decrease the diameter of the lumen. The restricted flow then increases the thrombogenicity, making full occlusion even more likely. Other problems are preparation and preservation of the autograft, procedures that can result in vessel damage or diminished in vivo performance. Finally, due to increased and/or different mechanical forces, endothelial cells can shrink, diminishing barrier performance, and degrade, also resulting in increased thrombogenicity. In order to reduce thrombus formation anticoagulation drugs are necessary. The use of these drugs often results in undesirable systemic side effects and can be very problematic. Therefore synthetic materials are poor choices for materials for small diameter vascular grafts.
By incorporating biological materials into a synthetic vascular graft the host response can be modulated to help insure that the graft will not fail. The use of collagen as a material for a synthetic vascular graft is quite promising because it is biodegradable and has good mechanical properties. Since collagen is biodegradable, as the device degrades tissue can grow into the device. This is advantageous because ideally as the collagen implant degrades the newly formed tissue will replace it, which results in a gradual transfer of stress from the implanted device to the newly formed tissue.
If a collagen vascular implant material was seeded with endothelial cells so that they coat the lumen, the surface would theoretically be more biocompatible. Recently, endothelial cells have been cultured onto the collagen small diameter vascular grafts. Therefore by incorporating biodegradable peptides into the collagen vascular implant material, endothelial cells can be seeded onto the top of the material to create a lumenal surface that is comprised of endothelial cells to more closely mimic the natural biological environment. Migration of endothelial cells on biomaterials is very important for the development of implantable devices. These cell property controls the rates of reendothelization and angiogenesis that are important for the success of the implant.
Angiogenesis is a complex, multi-stage process by which new blood vessels are formed from pre-existing vasculature. Two critical steps in this process are endothelial cell migration and assembly into new tubules. Over the last decade, diverse arrays of molecular regulators that participate in the process of angiogenesis have been identified. The receptor tyrosine kinases, for example, are one such family of angiogenesis regulators that play a prominent role in endothelial cell assembly and migration.

Pharmaceutical compositions
Still another aspect of the present invention relates to the use of a peptide combination as an active ingredient, together with at least one pharmaceutically acceptable carrier, excipient and/or diluents for the manufacture of a pharmaceutical composition for the treatment and/or prophylaxis of cancer, an autoimmune disease, a fibrotic disease, an inflammatory disease, a neurodegenerative disease, an infectious disease, a lung disease, a heart and vascular disease or a metabolic disease or any other disease disclosed herein. Such pharmaceutical compositions comprise the peptide combination as an active ingredient, together with at least one pharmaceutically acceptable carrier, excipient, binders, disintegrates, glidents, diluents, lubricants, coloring agents, sweetening agents, flavoring agents, preservatives or the like. The pharmaceutical compositions of the present invention can be prepared in a conventional solid or liquid carrier or diluents and a conventional pharmaceutically-made adjuvant at suitable dosage level in a known way. Preferably, the two peptides are contained in the combination in an amount from 20% by weight of peptide 1 to 80% by weight of peptide 2 to 80% by weight of peptide 1 to 20% by weight of peptide 2. More preferably, the two peptides are contained in the combination in an amount from 30% by weight of peptide 1 to 70% by weight of peptide 2 to 70% by weight of peptide 1 to 30% by weight of peptide 2. Still more preferably the two peptides are contained in the combination in an amount from 40% by weight of peptide 1 to 60% by weight of peptide 2 to 60% by weight of peptide 1 to 40% by weight of peptide 2.
Preferably the peptide combination is suitable for intravenous administration or suitable for oral administration or suitable for administration by inhalation.
Administration forms include, for example, pills, tablets, film tablets, coated tablets, capsules, liposomal formulations, micro- and nano-formulations, powders and deposits. Furthermore, the present invention also includes pharmaceutical preparations for parenteral application, including dermal, intradermal, intragastral, intracutan, intravasal, intravenous, intramuscular, intraperitoneal, intranasal, intravaginal, intrabuccal, percutan, rectal, subcutaneous, sublingual, topical, or transdermal application, which preparations in addition to typical vehicles and/or diluents contain the peptide combination according to the present invention.
The present invention also includes mammalian milk, artificial mammalian milk as well as mammalian milk substitutes as a formulation for oral administration of the peptide combination to newborns, toddlers, and infants, either as pharmaceutical preparations, and/or as dietary food supplements.
The peptide combination of the invention can also be administered in form of its pharmaceutically active salts. Suitable pharmaceutically active salts comprise acid addition salts and alkali or earth alkali salts. For instance, sodium, potassium, lithium, magnesium or calcium salts can be obtained.
The peptide combination of the invention forms pharmaceutically acceptable salts with organic and inorganic acids. Examples of suitable acids for such acid addition salt formation are hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, acetic acid, citric acid, oxalic acid, malonic acid, salicylic acid, p-aminosalicylic acid, malic acid, fumaric acid, succinic acid, ascorbic acid, maleic acid, sulfonic acid, phosphonic acid, perchloric acid, nitric acid, formic acid, propionic acid, gluconic acid, lactic acid, tartaric acid, hydroxymaleic acid, pyruvic acid, phenylacetic acid, benzoic acid, p-aminobenzoic acid, p-hydroxybenzoic acid, methanesulfonic acid, ethanesulfonic acid, nitrous acid, hydroxyethanesulfonic acid, ethylenesulfonic acid, p-toluenesulfonic acid, naphthylsulfonic acid, sulfanilic acid, camphersulfonic acid, china acid, mandelic acid, o-methylmandelic acid, hydrogen-benzenesulfonic acid, picric acid, adipic acid, D-o-tolyltartaric acid, tartronic acid, α-toluic acid, (o, m, p)- toluic acid, naphthylamine sulfonic acid, and other mineral or carboxylic acids well known to those skilled in the art. The salts are prepared by contacting the free base form with a sufficient amount of the desired acid to produce a salt in the conventional manner.
The pharmaceutical compositions according to the present invention will typically be administered together with suitable carrier materials selected with respect to the intended form of administration, i.e. for oral administration in the form of tablets, capsules (either solid filled, semi-solid filled or liquid filled), powders for constitution, aerosol preparations consistent with conventional pharmaceutical practices. Other suitable formulations are gels, elixirs, dispersible granules, syrups, suspensions, creams, lotions, solutions, emulsions, suspensions, dispersions, and the like. Suitable dosage forms for sustained release include tablets having layers of varying disintegration rates or controlled release polymeric matrices impregnated with the active components and shaped in tablet form or capsules containing such impregnated or encapsulated porous polymeric matrices. The pharmaceutical compositions may be comprised of 5 to 95% by weight of the peptide combination while also up to 100% of the pharmaceutical composition can consist of the peptide combination.
As pharmaceutically acceptable carrier, excipient and/or diluents can be used lactose, starch, sucrose, cellulose, magnesium stearate, dicalcium phosphate, calcium sulfate, talc, mannitol, ethyl alcohol (liquid filled capsules).
Suitable binders include starch, gelatin, natural sugars, corn sweeteners, natural and synthetic gums such as acacia, sodium alginate, carboxymethyl-cellulose, polyethylene glycol and waxes. Among the lubricants that may be mentioned for use in these dosage forms, boric acid, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrants include starch, methylcellulose, guar gum and the like. Sweetening and flavoring agents and preservatives may also be included where appropriate. Some of the terms noted above, namely disintegrants, diluents, lubricants, binders and the like, are discussed in more detail below.
Additionally, the compositions of the present invention may be formulated in sustained release form to provide the rate controlled release of any one or more of the components or active ingredients to optimize the therapeutic effects. Suitable dosage forms for sustained release include layered tablets containing layers of varying disintegration rates or controlled release polymeric matrices impregnated with the active components and shaped in tablet form or capsules containing such impregnated or encapsulated porous polymeric matrices.
Aerosol preparations suitable for inhalation may include solutions and solids in powder form, which may be in combination with a pharmaceutically acceptable carrier such as inert compressed gas, e.g. nitrogen.
For preparing suppositories, a low melting wax such as a mixture of fatty acid glycerides such as cocoa butter is first melted, and the active ingredient is dispersed homogeneously therein by stirring or similar mixing. The molten homogeneous mixture is then poured into convenient sized molds, allowed to cool and thereby solidify.
Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for either oral or parenteral administration. Such liquid forms include solutions, suspensions and emulsions.
The peptides of the present invention may also be deliverable transdermally. The transdermal compositions may take the form of creams, lotions, aerosols and/or emulsions and can be included in a transdermal patch of the matrix or reservoir type as are conventional in the art for this purpose.
The transdermal formulation of the peptide/s of the invention is understood to increase the bioavailability of said peptide into the circulating blood. One problem in the administration of peptides is the loss of bioactivity due to the formation of insolubles in aqueous environments or due to degradation. Therefore stabilization of peptides for maintaining their fluidity and maintaining their biological activity upon administration to the patients in need thereof needs to be achieved. Prior efforts to provide active agents for medication include incorporating the medication in a polymeric matrix whereby the active ingredient is released into the systemic circulation. Known sustained-release delivery means of active agents are disclosed, for example, in US4235988, US4188373, US4100271 , US447471 , US4474752, US4474753, or US4478822 relating to polymeric pharmaceutical vehicles for delivery of pharmaceutically active chemical materials to mucous membranes. The pharmaceutical carriers are aqueous solutions of certain polyoxyethylene-polyoxypropylene condensates. These polymeric pharmaceutical vehicles are described as providing for increased drug absorbtion by the mucous membrane and prolonged drug action by a factor of two or more. The substituents are block copolymers of polyoxypropylene and polyoxyethylene used for stabilization of drugs such as insulin.
Aqueous solutions of polyoxyethylene-polyoxypropylene block copolymers (poloxamers) are useful as stabilizers for peptides. Aside from serving as a stabilizer for the peptides, poloxamers provide excellent vehicles for the delivery of the peptides, and they are physiologically acceptable. Poloxamers, also known by the trade name Pluronics (e.g. Pluronic F127, Pluronic P85, Pluronic F68) have surfactant properties that make them useful in industrial applications. Among other things, they can be used to increase the water solubility of hydrophobic, oily substances or otherwise increase the miscibility of two substances with different hydrophobicities. For this reason, these polymers are commonly used in industrial applications, cosmetics, and pharmaceuticals. They have also been used as model systems for drug delivery applications. In situ gelation of pharmaceutical compositions based on poloxamer that are biologically triggered are known in the art
(e.g. US5256396), describing compositions containing poloxamer 407 and water at specified concentrations.
The term capsule refers to a special container or enclosure made of methyl cellulose, polyvinyl alcohols, or denatured gelatins or starch for holding or containing compositions comprising the active ingredients. Hard shell capsules are typically made of blends of relatively high gel strength bone and pork skin gelatins. The capsule itself may contain small amounts of dyes, opaquing agents, plasticizers and preservatives.
Tablet means compressed or molded solid dosage form containing the active ingredients with suitable diluents. The tablet can be prepared by compression of mixtures or granulations obtained by wet granulation, dry granulation or by compaction well known to a person skilled in the art. Oral gels refers to the active ingredients dispersed or solubilized in a hydrophilic semi-solid matrix.
Powders for constitution refer to powder blends containing the active ingredients and suitable diluents which can be suspended in water or juices. One example for such an oral administration form for newborns, toddlers and/or infants is a human breast milk substitute which is produced from milk powder and milk whey powder, optionally and partially substituted with lactose.
Human breast milk is a complex fluid, rich in nutrients and in non-nutritional bioactive components. It contains all of the nutrients needed by the newborn baby. These include the metabolic components (fat, protein, and carbohydrates), water, and the raw materials for tissue growth and development, such as fatty acids, amino acids, minerals, vitamins, and trace elements.
More than 98% of the fat in is in the form of triglycerides. Oleic acid and palmitic acid are the most abundant fatty acids in breastmilk triglycerides, with comparatively high proportions of the essential fatty acids, and linolenic acid, followed by long-chain polyunsaturated fatty acids, such as arachidonic acid and docosahexaenoic acid. These long-chain fatty acids are constituents of brain and neural tissue and are needed in early life for mental and visual development. The lipid component of breast milk is the transport vehicle for fat-soluble micronutrients such as prostaglandins and vitamins A, D, E, and K.
Proteins account for approximately 75 % of the nitrogen-containing compounds in breast milk. Non-protein nitrogen substances include urea, nucleotides, peptides, free amino acids, and DNA. The proteins of breast milk can be divided into two categories: micellar caseins and aqueous whey proteins, present in the ratio of about 40:60. Casein forms micelles of relatively small volume and produces a soft, flocculent curd in the infant's stomach. The major whey proteins are lactalbumin, lactoferrin, secretory IgA, and serum albumin, with a large number of other proteins and peptides present in smaller amounts.
The principal carbohydrate is lactose, a disaccharide produced in the mammary epithelial cell from glucose by a reaction involving lactalbumin.
In addition to the nutritional components, breast milk contains a wealth of bioactive components that have beneficial non-nutritional functions. These include a wide range of specific and non-specific antimicrobial factors; cytokines and anti- inflammatory substances; and hormones, growth modulators, and digestive enzymes (Table 1 ), many of which have multiple activities. These components may be of particular importance for young infants because of the immaturity of the host defense and digestive systems early in life.
TABLE 2. Examples of the non-nutritional components of breast milk
Figure imgf000075_0001
Besides breast milk, infant formula is the only other infant milk which the medical community considers nutritionally acceptable for infants under the age of one year. Cow's milk is not recommended because of its high protein and electrolyte (salt) content which may harm infant's immature kidneys. The nutrient content of infant formula should comprise: Protein, Fat, Linoleic acid, Vitamins: A, C, D, E, K, thiamin (B1 ), riboflavin (B2), B6, B12, Niacin, Folic acid, Pantothenic acid, Calcium, Metals: magnesium, iron, zinc, manganese, copper; Phosphorus, Iodine, Sodium chloride, Potassium chloride. In addition, formulas not made with cow's milk must include biotin, choline, and inositol. Hypoallergenic formulas reduce the likelihood of certain medical complications in babies with specific health problems. Baby formula can be synthesized from raw amino acids. This kind of formula is sometimes referred to as elemental infant formula or as medical food because of its specialized nature.
Powder blends containing the active ingredients and suitable diluents which can be suspended in water or juices can be produced by spray drying.
Spray drying has been found the most suitable process for removing the last part of the water, since spray drying can convert milk concentrate into a powder while still keeping the valuable properties of the milk. The principle of all spray dryers is to transform the concentrate into many small droplets which are then exposed to a fast current of hot air. Because of the very large surface area of the droplets, the water evaporates almost instantaneously and the droplets are transformed into powder particles.
Powdered milk is a powder made from dried milk solids. Powdered milk has a far longer shelf life than liquid milk and does not need to be refrigerated due to its low moisture content.
Instant milk powder is produced by partially rehydrating the dried milk powder particles causing them to become sticky and agglomerate. The water is then removed by drying resulting in an increased amount of air incorporated between the powder particles.
Milk powder manufacture is a process carried out on a large scale. It involves the gentle removal of water, while retaining all the desirable natural properties of the milk like colour, flavour, solubility, nutritional value.
Milk powder process includes spray drying, fluid bed processing, extraction, evaporation and freeze drying. Other processes are freeze concentration, filteration, and homogenisation.
The artificial mother milk formulations or mother milk substitutes of the present invention are preferably prepared by adding to a mother milk formulation including commercially available mother milk formulations especially in powder form the inventive peptide combination. The peptide combination is preferably added in an amount of 3 - 100 μg peptide combination per 100 ml (commercially available) mother milk formulation, more preferably in an amount of 5 - 70 μg / 100 ml and most preferably in an amount of 10 - 40 μg / 100 ml mother milk formulation.
Suitable diluents are substances that usually make up the major portion of the composition or dosage form. Suitable diluents include sugars such as lactose, sucrose, mannitol and sorbitol, starches derived from wheat, corn rice and potato, and celluloses such as microcrystalline cellulose. The amount of diluents in the composition can range from about 5 to about 95% by weight of the total composition, preferably from about 25 to about 75%, more preferably from about 30 to about 60% by weight, and most preferably from about 40 to 50% by weight.
The term disintegrants refers to materials added to the composition to help it break apart (disintegrate) and release the medicaments. Suitable disintegrants include starches, "cold water soluble" modified starches such as sodium carboxymethyl starch, natural and synthetic gums such as locust bean, karaya, guar, tragacanth and agar, cellulose derivatives such as methylcellulose and sodium carboxymethylcellulose, microcrystalline celluloses and cross-linked microcrystalline celluloses such as sodium croscarmellose, alginates such as alginic acid and sodium alginate, clays such as bentonites, and effervescent mixtures. The amount of disintegrant in the composition can range from about 1 to about 40% by weight of the composition, preferably 2 to about 30% by weight of the composition, more preferably from about 3 to 20% by weight of the composition, and most preferably from about 5 to about 10% by weight.
Binders characterize substances that bind or "glue" powders together and make them cohesive by forming granules, thus serving as the "adhesive" in the formulation. Binders add cohesive strength already available in the diluents or bulking agent. Suitable binders include sugars such as sucrose, starches derived from wheat, corn rice and potato; natural gums such as acacia, gelatin and tragacanth; derivatives of seaweed such as alginic acid, sodium alginate and ammonium calcium alginate; cellulosic materials such as methylcellulose and sodium carboxymethylcellulose and hydroxypropyl-methylcellulose; polyvinylpyrrolidone; and inorganics such as magnesium aluminum silicate. The amount of binder in the composition can range from about 1 to 30% by weight of the composition, preferably from about 2 to about 20% by weight of the composition, more preferably from about 3 to about 10% by weight, even more preferably from about 3 to about 6% by weight. Lubricant refers to a substance added to the dosage form to enable the tablet, granules, etc. after it has been compressed, to release from the mold or die by reducing friction or wear. Suitable lubricants include metallic stearates such as magnesium stearate, calcium stearate or potassium stearate; stearic acid; high melting point waxes; and water soluble lubricants such as sodium chloride, sodium benzoate, sodium acetate, sodium oleate, polyethylene glycols and d'l-leucine. Lubricants are usually added at the very last step before compression, since they must be present on the surfaces of the granules and in between them and the parts of the tablet press. The amount of lubricant in the composition can range from about 0.05 to about 15% by weight of the composition, preferably 0.2 to about 5% by weight of the composition, more preferably from about 0.3 to about 3%, and most preferably from about 0.3 to about 1.5% by weight of the composition.
Glidents are materials that prevent caking and improve the flow characteristics of granulations, so that flow is smooth and uniform. Suitable glidents include silicon dioxide and talc. The amount of glident in the composition can range from about 0.01 to 10% by weight of the composition, preferably 0.1 % to about 7% by weight of the total composition, more preferably from about 0.2 to 5% by weight, and most preferably from about 0.5 to about 2% by weight.
Coloring agents are excipients that provide coloration to the composition or the dosage form. Such excipients can include food grade dyes and food grade dyes adsorbed onto a suitable adsorbent such as clay or aluminum oxide. The amount of the coloring agent can vary from about 0.01 to 10% by weight of the composition, preferably from about 0.05 to 6% by weight, more preferably from about 0.1 to about 4% by weight of the composition, and most preferably from about 0.1 to about 1 %.
Peptides of the invention can be used to form multiparticulates, discrete particles, well known dosage forms, whose totality represents the intended therapeutically useful dose of a drug. When taken orally, multiparticulates generally disperse freely in the gastrointestinal tract, and maximize absorption. A specific example is described in US 6068859, disclosing multiparticulates that provide controlled release of azithromycin. Another advantage of the multiparticulates is the improved stability of the drug. The poloxamer component of the multiparticulate is very inert, thus minimizing degradation of the drug.
However, formulation problems result from the melt-congeal process often used to form multiparticulates. The multiparticulates are preferably formed into round beads or spheres. Some carriers, when melted and then solidified, do not form round beads but may solidify into rods, strings, or other non-spherical shapes. The result is very irregularly shaped multiparticulates that are difficult to process into dosage forms. This problem is solved by e.g. WO 2007104173 where the particles consist of a poloxamer, a resin, and/or a tocopherol, creating together with the medicament (e.g. insulin) micelles. Micelle formation is essential for the absorption of many nutrients within the human body. Bile salts formed in the liver and secreted by the gall bladder allow micelles of fatty acids to form. This allows the absorption of complicated lipids and lipid soluble vitamins within the micelle by the small intestine. Micelles are approximately spherical in shape. Preferably, peptides of the invention are formulated with a poloxamer and a resin to form micelles suitable for oral administration to patients in need of the medicament.
Liquid form preparations include solutions, suspensions and emulsions. As an example may be mentioned water or water-propylene glycol solutions for parenteral injections or addition of sweeteners and opacifiers for oral solutions, suspensions and emulsions. Liquid form preparations may also include solutions for intranasal administration.

For administration by inhalation the particle diameter of the lyophilised preparation is preferably between 2 to 5 μm, more preferably between 3 to 4 μm. The lyophilised preparation is particularly suitable for administration using an inhalator, for example the OPTINEB® or VENTA-NEB® inhalator (NEBU-TEC, Elsenfeld, Germany). The lyophilised product can be rehydrated in sterile distilled water or any other suitable liquid for inhalation adminstration.
Alternatively for intravenous administration the lyophilised product can be rehydrated in sterile distilled water or any other suitable liquid for intravenous administration.
After rehydration for administration in sterile distilled water or another suitable liquid the lyophilised preparation should have the approximate physiological osmolality of the target tissue for the rehydrated peptide preparation i.e. blood for intravenous administration or lung tissue for inhalation administration. Thus it is preferred that the rehydrated formulation is substantially isotonic.
The preferred dosage concentration for either intravenous, oral, or inhalation administration is between 100 to 2000 μmole/ml, and more preferably is between 200 to 800 μmole/ml.

The peptides as listed above and the inventive peptide combination with approximately equimolar amounts of the two peptides (deviation ±10%) were tested for activity using the assays described in Examples 1 to 18. The tested peptides are all commercially available and are all known petides and well described and characterized in the state of the art literature. The inventive peptide combination was prepared by simply mixing the two commercially available peptides in a molar ratio, for instance, between 0.9 to 1.1 and 1.1 to 0.9 (referred to as "approximately equimolar amounts") or other ratios such as from 0.5 - 1.5 to 1.5 - 0.5. It has to be mentioned that the biological data obtained with the peptide combinations in molar ratios between 0.4 to 1.6 mole (peptide 1 to peptide 2) and 1.6 to 0.4 mol (peptide 1 to peptide 2) were in general very similar to the biological data obtained with the equimolar peptide combinations so that in most cases the data for the equimolar (from 0.9 : 1.1 to 1.1 : 0.9) combinations are cited herein. Further data are presented only in these cases where the biological data of the peptide combinations with non equimolar amunts of the peptides differ more than 20% from the biological data of the equimolar combination.
The term "peptides" as used in the following examples refers to peptide 1 , peptide 2 and the peptide combination and the concentration of "10 micrograms per ml" refers to 10 μg peptide 1 per ml or 10 μg peptide 2 per ml or 10 μg peptide combination per ml.
Thus the term "peptides" in the following examples indicates that the test disclosed in the corresponding example was conducted with peptide 1 alone and peptide 2 alone and with the peptide combination generally in equimolar ratios (molar ratio about 1 : 1 for peptide 1 : peptide 2) if no other molar ratio is mentioned in the corresponding example.
EXAMPLE 1 :
HIV-1 Experiments
CEM-SS cells were passaged in T-75 flasks prior to use in the antiviral assay. On the day preceding the assay, the cells were split 1 :2 to assure they were in an exponential growth phase at the time of infection. Total cell viability quantification was performed using a hemacytometer and trypan blue exclusion. Cell viability was greater than 95% for the cells to be utilized in the assay. The cells were resuspended at 5 X 104 cells/ml in tissue culture medium and added to the peptides-containing microtiter plates in a volume of 50 microliters. The virus used was the lymphocytotropic strain HIV-1 ιnB. Virus was obtained from NIH AIDS Research and Reference Reagent Program and was grown in CEM-SS cells for the production of stock virus pools. For each assay, a pre-titered aliquot of virus was removed from the freezer (-800C) and allowed to thaw slowly to room temperature in a biological safety cabinet. The virus was resuspended and diluted into tissue culture medium such that the amount of virus added to each well in a volume of 50 microliters was the amount determined to give between 85% to 95% cell killing after 6 days post-infection. TCID50 calculations by endpoint titration in CEM-SS cells indicated that the multiplicity of infection was approximately 0.01. AZT (nucleoside reverse transcriptase inhibitor; NRTI) and indinavir (protease inhibitor; Pl) were used as positive control antiviral compounds.
Plate format Each plate contained cell control wells (cells only), virus control wells (cells plus virus), drug cytotoxicity wells (cells plus peptides only), peptide colorimetric control wells (peptide only) as well as experimental wells (peptides - 10 micrograms per ml - plus cells plus virus). Samples were evaluated for antiviral efficacy with triplicate measurements and with duplicate measurements to determine cellular cytotoxicity, if detectable.
At assay termination, the plates were stained with the soluble tetrazolium-based dye MTS (CellTiter 96 Reagent, Promega) to determine cell viability and quantify peptides' toxicity. MTS is metabolized by the mitochondrial enzymes of metabolically active cells to yield a soluble formazan product, allowing the rapid quantitative analysis of cell viability and peptide cytotoxicity. This reagent is a stable, single solution that does not require preparation before use. At assay termination, 20-25 microliters of MTS reagent was added per well and the microtiter plates were then incubated for 5 hours at 370C, and 5% CO2 to assess cell viability. Adhesive plate sealers were used in place of lids, the sealed plates were inverted several times to mix the soluble formazan product and the plate was read spectrophotometrically at 490/560 nm with a Molecular Devices Vmax plate reader.
The overall assay performance was valid based upon judgement of the positive control compounds AZT and indinavir exhibiting the expected levels of antiviral activity. Macroscopic observation of the cells in each well of the microtiter plate confirmed the cytotoxicity results obtained following staining of the cells with the MTS metabolic dye. Results from HIV experiments: The peptide combination of the invention showed no inhibition of HIV-1 activity on tested T-cells. In addition, the peptides of the invention did not show any significant inhibitory effects on cell viability in these human T-cells.

HBV Experimental Assay System
HepG2-2.2.15 is a stable cell line containing the hepatitis B virus (HBV) ayw strain genome (ATCC Cat. No. CRL-11997). Antiviral compounds blocking any late step of viral replication such as transcription, translation, pregenome encapsidation, reverse transcription, particle assembly and release can be identified and characterized using this cell line. In this assay, an active compound will reduce the production of secreted HBV from cells, measured by utilizing real time quantitative PCR (TaqMan) assay to directly and accurately measure HBV DNA copies. The analysis of this data allows to calculate: * Antiviral activity
* Compound Cytotoxicity
HepG2-2.2.15 cells were plated in 96-well microtiter plates. After 16-24 hours the confluent monolayer of HepG2-2.2.15 cells was washed and the medium was replaced with complete medium containing test peptides - 10 micrograms per ml - in duplicate. Lamivudine (3TC) was used as the positive control, while media alone was added to the cells as a negative control (virus control). Three days later the culture medium was replaced with fresh medium containing the peptides. Six days following the initial administration of the peptides, the cell culture supernatants was collected, treated with pronase and DNAse and then used in a real-time quantitative TaqMan PCR assay. The PCR-amplified HBV DNA was detected in real-time by monitoring increases in fluorescence signals that result from the exonucleolytic degradation of a quenched fluorescence probe molecule that hybridizes to the mplified HBV DNA. For each PCR amplification, a standard curve was simultaneously generated using dilutions of purified HBV DNA. Antiviral activity was calculated from the reduction in HBV DNA levels (% virus control). A novel dye uptake assay was then employed to measure cell viability, which is used to calculate toxicity (% cell control).
Results from HBV experiments: Peptide 1 inhibited by 8.2% HBV replication on tested liver cells. Peptide 2 inhibited by 9.7% HBV replication as compared to the virus control infection. The peptide combination did not provide synergistic effects. In addition, the peptides of the invention did not show any significant inhibitory effects on cell viability in these human liver cells.

EXAMPLE 8:
Cell cycle assay
Human A549 cells (carcinomic human alveolar basal epithelial cells) were utilized in the experiments employing the Propidium iodide cell cycle assay. The eukaryotic cell cycle is a series of events that take place in a cell leading to its replication.
The regulation of the cell cycle involves steps crucial to the cell, including detecting and repairing genetic damage, and provision of various checks to prevent uncontrolled cell division. The molecular events that control the cell cycle are ordered and directional; that is, each process occurs in a sequential fashion.
The cell cycle consists of four distinct phases: G1 phase, S phase, G2 phase (collectively known as interphase) and M phase. M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's chromosomes are divided between the two daughter cells, and cytokinesis, in which the cell's cytoplasm divides forming distinct cells. Activation of each phase is dependent on the proper progression and completion of the previous one. Cells that have temporarily or reversibly stopped dividing are said to have entered a state of quiescence called GO phase. The relatively brief M phase consists of nuclear division and cytoplasmic division. The first phase within interphase, from the end of the previous M phase till the beginning of DNA synthesis is called G1 (G indicating gap or growth). During this phase the biosynthetic activities of the cell resume at a high rate. This phase is marked by synthesis of various enzymes that are required in S phase, mainly those needed for DNA replication. The ensuing S phase starts when DNA synthesis commences; when it is complete, all of the chromosomes have been replicated. The cell then enters the G2 phase, which lasts until the cell enters mitosis. Significant protein synthesis occurs during this phase, mainly involving the production of microtubules, which are required during the process of mitosis. Inhibition of protein synthesis during G2 phase prevents the cell from undergoing mitosis. Disregulation of the cell cycle components may lead to tumor formation.
Propidium iodide is an intercalating agent and a fluorescent molecule that can be used to stain DNA. Cells were incubated for 24 hours with test peptides - 10 micrograms per ml - or left untreated. After that cells were trypsinized, suspended in medium + 10% FCS, centrifuged (1000 rpm, 5 min), and the cell pellet resuspended in PBS (1 ml).

After the cells were incubated for additional 60 min at 37°C and allowed to ingest the Fluorescein-labeled Escherichia coli bacteria, cells were fixed with 1 % paraformaldehyde. The samples were then analyzed by flow cytometry to determine the amount of phagocytosis as a function of brightness (the greater the phagocytic activity, the more fluorescence in the macrophage population). Data are reported as % positive and the mean fluorescence intensity (MFI) of positively stained cells.

Primary Human endothelial cells (HUVEC) were seeded in insert chambers with 3 micrometer pore size of multi-transwell plate for 6 hours at 37°C in Endothelial Cell Basal Medium (EBM) supplemented with 0.1% bovine serum albumin. Thereafter, designated concentration of testing peptides - 10 micrograms per ml - was added in duplicate wells. The endothelia were allowed to migrate for 22 hours at 370C, then, migrated cells were fixed and stained with Hoechst 33342 dye. Images of 3 fields per insert were taken and the number of migrated cells per field were quantified using the ImageProPlus software. Data were analyzed for the average number of the migrated cells and standard deviation of six data points for each treatment condition. Active test peptides against HUVEC migration was determined based on 50% inhibition of migrated cells as compared with the control. Statistic p values were computed using the Student's t-test.
Results from endothelial cell migration assay: Peptide 1 inhibited by 2% the migration of human endothelial cells, peptide 2 inhibited by 16% the migration of endothelial cells, and the peptide combination (peptide 1 : peptide 2 (0.95 mole : 1.05 mole)) inhibited by 10% the migration of human endothelial cells.
EXAMPLE 17:

Raw data were expressed as average tubule lenghs in pixels ± standard deviation. Statistic p values were computed using the Student's t-test. Results from endothelial tube formation assay: Peptide 1 inhibited by 10% the tube formation of human endothelial cells, peptide 2 inhibited by 5% the tube formation endothelial cells, and the peptide combination (peptide 1 : peptide 2 (0.95 mole : 1.05 mole) inhibited by 11 % the tube formation of human endothelial cells.
EXAMPLE 18 cAMP induction assay
Adenosine 3\ 5'-cyclic monophosphate (cyclic AMP; cAMP) is one of the most important "second messengers" involved as a modulator of physiological processes. cAMP is also involved in regulating neuronal, glandular, cardiovascular, immune and other functions and actions in a regulatory way. For being a second messenger, cAMP has the following characteristics to work effectively: 1 ) Amplification - when a few peptide molecules signal the cell, it needs to respond with a signal that is strong enough to get a job done without repeated high levels of stimulation. 2) Control — eventually a response must be shut down, and there are instances when its necessary to respond a little or a lot - so control is needed. 3) Specificity - when a peptide is utilized, a given cell should respond in a specific way. Not all cells will respond to this peptide and therefore they cannot have the same effect in all the cells. Elevated levels of cAMP in human cells are associated with the suppression of cell activation.
The cAMP kit was used as an immunoassay for the quantitative determination of cyclic AMP generation in human peripheral blood mononuclear cells (PBMC). PBMC were placed in 96-well microtitier plates (50 microliters of cells at 4x106/ml) and 50 microliters of medium alone (background control), forskolin (cAMP positive control; 50 micrograms per ml), or test peptides - 10 micrograms per ml - were added. Plates were mixed and incubated for 10 min at 37°C and the cells were lysed by the addition of 50 microliters of 3% perchloric acid. NaOH was added to neutralize the samples. Plates were centrifuged for 15 min at 2500 rpm and the supematants removed. The supematants (diluted 2-fold in assay buffer) were then assayed for the levels of cAMP by ELISA.
Results from cAMP induction assay: Peptides of the invention and the peptide combination had no effects on cAMP formation in human peripheral blood cells.
