Definitions
- the present invention relates to a derivative of a human glucagon-like peptide-1 (GLP-1) analog or a pharmaceutically acceptable salt thereof, and the derivative of the GLP-1 analogue provided by the present invention has the function of human GLP-1, and It has a longer half-life in vivo compared to human GLP-1.
- the present invention also relates to a pharmaceutical composition of a derivative of a GLP-1 analogue or a pharmaceutically acceptable salt thereof or a derivative containing the GLP-1 analogue or a pharmaceutically acceptable salt thereof for the treatment of non-insulin dependent diabetes, insulin dependence Use of diabetes and obesity. Background technique
- Diabetes is a global epidemic, a syndrome of glucose, protein, and lipid metabolism caused by absolute or relative deficiency of insulin in the body (Chen Ruijie. Research status of diabetes drugs. Journal of Guangdong College of Pharmacy, 2001, 7( 2): 131-133), according to the pathogenesis can be divided into type I and type II diabetes (Type 2 diabetes mellitus, T2DM, the same below).
- Type 2 diabetes mellitus Type 2 diabetes mellitus, T2DM, the same below.
- T2DM Type 2 diabetes mellitus
- T2DM is characterized by insulin inhibition and pancreatic ⁇ -cell dysfunction, leading to insulin deficiency and insulin deficiency in non-insulin-dependent diabetes mellitus: problems and prospects. Endocr Rev. 1998, 19 (4 ): 477 ⁇ 90). T2DM patients usually have a meal and fasting blood Sugar (fasting blood glucose > 125 mg/dL), and hyperglycemia is mainly due to the fact that pancreatic ⁇ -cells cannot secrete enough insulin to compensate for insulin inhibition in peripheral tissues (Weyer C, Bogardus C, Mott DM., et al. The Natural history of insulin secretory dysfunction and insulin resistance in the pathogenesis of type 2 diabetes mellitus. J. Clin. Invest. 1999, 104(6): 787-794).
- the main risk factor for T2DM is obesity, which is very harmful to human health. Patients are at increased risk of developing cardiovascular disease and abnormal death, and T2DM is often associated with other high-risk diseases such as hypertension, dyslipidemia, and obesity; 60% of patients with T2DM are accompanied by microvascular complications. Retinopathy and neuropathy and cardiovascular morbidities associated with T2DM such as coronary heart disease, myocardial infarction, and shock. In the United States, cardiovascular disease (CVD) is a major cause of morbidity and mortality, while T2DM is a macrovascular complication such as atherosclerosis, myocardial infarction, shock and sputum. The main risk factor for the occurrence of vascular disease in the week. In adults with diabetes, heart disease and shock are 2-4 times more likely to die than non-diabetics. In addition, nearly 65% of people with diabetes die from heart disease and shock.
- T2DM In addition to physical and physical harm to patients, T2DM also imposes a large economic burden on society. According to statistics, the annual cost of treating diabetes complications in the United States is approximately $22.9 billion, which is used annually for T2DM and its complications. The total cost is close to $57.1 billion, and the total unbudgeted cost exceeds $8 billion.
- T2DM therapeutics have always been the focus of attention, from early sulfonamides, biguanide oral hypoglycemic agents to recent insulin sensitizers and alpha-glucosidase inhibitors, from animal insulin to human insulin and various new dosage forms. Development, from the simple mechanism of drug treatment to increase insulin to a new way to produce insulin earlier. Weight gain is a common side effect of this type of oral or hypoglycemic drug, which may reduce compliance and may increase the risk of developing cardiovascular disease. Therefore, the development of new T2DM therapeutic drugs with high safety, patient compliance and low adverse reactions has become a hot spot for many research institutions and pharmaceutical companies.
- GIP and GLP-1 are secreted by specific enteric neurosecretory cells during nutrient absorption, wherein GIP is secreted by the duodenum and adjacent jejunal K cells, and GLP-1 is synthesized in L cells. Mainly found in the distal small intestine and colon (Drucker DJ. Enhancing incretin action for the treatment of type 2 diabetes. Diabetes Care. 2003, 26(10): 2929-2940) o
- GLP-1 exists in the blood plasma in the form of two biologically active forms of GLP-1 (7-37) and GLP-1 (7-36) amide. These two polypeptides differ only in one amino acid, and their biological effects and in vivo The half-life is the same (Drucker DJ. Enhancing incretin action for the treatment of type 2 diabetes. Diabetes Care. 2003, 26(10): 2929-2940).
- GLP-1 is a general term for GLP-1 (7-37) and GLP-1 (7-36) amides.
- GIP and GLP-1 are rapidly degraded into inactive forms by dipeptidyl peptidase-IV (DPP-IV) in the gastrointestinal tract, resulting in GIP and GLP-1.
- DPP-IV dipeptidyl peptidase-IV
- the half-life in vivo is very low (GIP has an in vivo half-life of about 5-7 min and GLP-1 has a half-life of about 2 min in vivo) (Drucker DJ. Enhancing incretin action for the treatment of type 2 diabetes. Diabetes Care. 2003, 26(10): 2929-2940 ).
- GIP and GLP-1 enter the blood vessels containing DPP-IV, and a small amount of undegraded GLP-1 and GIP enter the pancreas and bind to its binding site to stimulate ⁇ -cell release. insulin.
- the incretin effect is mostly glucose-dependent.
- GLP-1 also has alpha-cell inhibition and reduced glucagon hypersecretion.
- T2DM patients have normal blood plasma GIP levels but their incretin effect is significantly reduced or lost, and GLP-1 levels are reduced in T2DM patients, the study of GLP-1 based drugs is more helpful in the treatment of T2DM.
- GLP-1 (7-37) and GLP-1 (7-36) amide levels increased in a few minutes after a meal, GLP-1 (7-36) amide content was more, so endocrine and neuronal signaling
- the dual effect can be on the digested food from the lower end of the digestive tract GLP-1 secretion has been greatly increased before entering the small intestine and colon.
- the GLP-1 level in the blood paddle was very low (about 5-10 pmol/L) in the fasting state, and its level increased rapidly after eating (up to 15-50 pmol/L).
- the level of GLP-1 circulating in the body rapidly decreases, while other enzymes such as human neutral endopeptidase 24.11 (human neutral endopeptidase 24-11) also affect GLP-1.
- Research work on the loss of activity plays a decisive role. Since GLP-1 is alanine at the 2-position amino acid, it is a good substrate for DPP-IV and is more susceptible to degradation to inactive peptides. In fact, DPP-IV is the main cause of loss of incretin activity in vivo.
- DLP-IV gene silenced mice significantly increased GLP-1 levels and increased insulin secretion. It is under the action of DPP-IV that the intact and biologically active GLP-1 is only 10-20% of the total GLP-1 content of blood plasma (Deacon CF, Nauck MA, Toft-Nielsen M, et al. Both subcutaneously And intravenously administered glucagon-like peptide 1 are rapidly degraded from the NH2-terminus in type 2-diabetic patients and in healthy subjects. Diabetes. 1995, 44(9): 1126-1131 ).
- GLP-1 and GIP pass through G-protein coupled receptors that are completely different in structure
- GIP receptors G-protein-coupled receptors, GPCRs
- GIP receptors Most of the GIP receptors are expressed by islet ⁇ -cells, and a small part is expressed in adipose tissue and the central nervous system.
- GLP-1 receptor is expressed mainly in islet ⁇ - and ⁇ -cells as well as in peripheral tissues including the central and peripheral nervous systems, brain, kidney, lung, and gastrointestinal tract.
- Activation of two incretins in beta-cells leads to a rapid increase in cAMP and intracellular calcium levels, leading to extracellular secretion in a glucose-dependent manner, and sustained incretin receptor signaling is associated with protein kinase A.
- Activation of GLP-1 and GIP receptors also inhibits ⁇ -cell apoptosis in rodents and human islets while increasing their survival rate (Li Y, Hansotia T, Yusta B, et al. Glucagon-like peptide- 1 receptor signaling Modulate beta cell apoptosis. J Biol Chem. 2003, 278(1): 471478 ).
- GLP-1 also inhibits glucagon secretion, gastric emptying, and food intake, while enhancing glucose degradation through a neural mechanism. It should be noted that, like other insulin secretion reactions, the effect of GLP-1 on glucose secretion is glucagon. Reactive regulation of glucagon due to hypoglycemia
- the glucagon effect of the counter-regulatory release of glucagon is still fully retained at the pharmacological concentration of GLP-1.
- GLP-1 and GIP The important physiological role of endogenous GLP-1 and GIP in glucose homeostasis has been extensively studied through the use of receptor antagonists or in knockout mice. Antagonism of acute GLP-1 or GIP reduces insulin secretion in rodents and increases blood glucose levels. Similarly, GIP or GLP-1 receptor-inactivated mutant mice also have defective glucose-stimulated insulin secretion and impaired glucose tolerance.
- GLP-1 also has a fasting blood glucose regulation function, because acute antagonism or genetic destruction of GLP-1 effects leads to an increase in fasting glucose levels in rodents; meanwhile, GLP-1 is the basis of glucose control in humans, antagonizing Exendin (9) -39) Studies have shown that disruption of GLP-1 results in defective glucose-stimulated insulin secretion, reduced glucose clearance, increased glucagon levels, and accelerated gastric emptying. Furthermore, the physiological role of GLP-1 (Deacon CF. Therapeutic strategies based on glucagon-like peptide 1. Diabetes.
- GLP-1 and GIP have a good effect in controlling blood sugar and other aspects, especially the characteristics of not producing hypoglycemia and delaying gastric emptying to control body weight have attracted the interest of many scientists.
- GLP-1 levels in T2DM patients are very low, and GLP-1 is produced by dietary stimulation. Significantly reduced levels (Toft-Nielsen MB, Damholt MB, Madsbad S, et al.
- GLP-1 analogues like endogenous GLP or GIP, can be glucose-dependent
- the method stimulates the secretion of insulin in the body while inhibiting the in vivo release of glucagon.
- GLP-1 analogues have effects on the following symptoms: (1) Hypoglycemia. Unlike other secretagogues, GLP-1 analogues are self-limiting in their ability to promote insulin secretion in a glucose-dependent manner, and generally do not cause severe hypoglycemia at high doses. Although it has been reported in the literature that GLP-1 can lower blood glucose below normal levels, this effect is transient and is considered to be a natural consequence of GLP-1 insulinotropic secretion. Since the inactivation of insulin requires a certain period of time, when the stimulation effect of GLP-1 is weakened and no new insulin is secreted due to a decrease in blood glucose concentration, the original insulin is still functioning.
- GLP-1 temporarily lowers blood glucose below normal levels, but does not cause severe and persistent hypoglycemia.
- the effect on satiety and weight In addition to directly lowering blood sugar, GLP-1 also reduces food intake, which has been proven in rodents and humans. This can indirectly control blood sugar levels by reducing body weight. GLP-1 also has the potential to inhibit gastric acid secretion from gastrin and feeding stimuli. These effects suggest that GLP-1 may also have a role in preventing peptic ulcers.
- the mechanism of action of GLP-1 not only makes it an ideal treatment for patients with type 2 diabetes, but also a therapeutic drug for obese diabetic patients.
- GLP-1 can enhance a patient's satiety, reduce food intake and maintain weight or lose weight; (maintaining beta-cell health. Some studies suggest that GLP-1 can prevent the conversion from impaired glucose tolerance to diabetes, and some literature reports GLP-1 compounds have a direct effect on the growth and proliferation of islet ⁇ cells in experimental animals, and it has been found that GLP-1 can promote the differentiation of pancreatic stem cells into functional ⁇ cells. These results suggest that GLP-1 has protective islets and The function of delaying the progression of diabetes can maintain the morphology and function of ⁇ -cells while reducing its apoptosis; (4) The effect on postprandial hyperglycemia. This phenomenon represents a new direction in the treatment of T2DM.
- GLP-1 analogues may be able to produce pancreatic hyperglycemia by directly inhibiting glucagon release or promoting paracrine inhibition by promoting insulin secretion The effect of high secretion is effective. These two mechanisms can effectively reduce postprandial hyperglycemia; Maintaining beta-cell function may also have an effect on long-term control of postprandial hyperglycemia.
- GLP-1 analogues are administered by subcutaneous injection, do not need to calculate the amount of carbohydrates to estimate the optimal drug dosage, and do not need to self-monitor blood glucose, making the use of such drugs more convenient than insulin.
- Exenatide is a synthetic Exendin-4, developed by Lilly and Amylin under the trade name Byetta®, FDA and EMEA, which have been approved for use in the treatment of T2DM. It is 50% homologous to mammalian GLP-1 and binds to the GLP-1 receptor affinity site ⁇ GLP-1 (Drucker DJ, Nauck MA. The incretin system: glucagon-like peptide- 1 receptor agonists and dipeptidyl peptidase-4 inhibitors in type 2 diabetes. Lancet.
- Exenatide will be the second in GLP-1 compared to GLP-1 Alanine is replaced by glycine, which effectively inhibits DPP-IV enzymatic hydrolysis and has a half-life of about 60-90 min in vivo (Kolterman OG, Kim DD, Shen L, et al. Pharmacokinetics, pharmacodynamics, and safety of exenatide in patients with type 2 Diabetes melllitus. Am Health Syst Pharm.
- Exenatide has specific glucose-regulating activities, including glucose-dependent enhancement of insulin secretion, glucose-dependent inhibition of excessive glucagon secretion, slowing of gastric emptying, and reduced food intake. In vivo and in vitro diabetes model studies have also found that Exenatide also has the role of storing first-phase insulin secretion, promoting beta-cell proliferation, and insulin regeneration from its precursor cells.
- Exenatide In order to achieve better blood sugar control, two injections of Exenatide are required every day, which brings great inconvenience to the patient. In addition, Exenatide also has mild to moderate nausea (about 40% of patients will have this reaction), diarrhea and vomiting (less than 15% of patients will have these two reactions); about 50% of Exenatide-treated patients will produce antibodies, Although these antibodies do not affect the efficacy or cause other clinical effects. Recently, 6 cases of bleeding or necrosis occurred after taking Byetta. The condition of pancreatic inflammation.
