Description

Composition and cosmetic composition for treating pancreatic cancer comprising extract

The present invention relates to a novel use of persimmon extract. Specifically, the present invention relates to a therapeutic composition and a cosmetic composition containing as an active ingredient extracts persimmon extract showing excellent preventive or therapeutic efficacy against pancreatic cancer.

Among the major diseases of modern people, researches on the treatment and diagnosis of cancer are being conducted mainly on lung cancer, liver cancer, and stomach cancer, which have high incidence. However, studies on esophageal cancer, colorectal cancer, and pancreatic cancer with low incidence are relatively low.

The pancreas produces insulin, which helps the body convert glucose into energy, and enzymes that help the body digest food. Pancreatic cancer is a malignant growth of the pancreas, mainly occurring in cells of the pancreatic duct. The disease is the ninth most common form of cancer, but it is the fourth and fifth most common cause of cancer deaths in men and women, respectively. Pancreatic cancer has a five-year survival rate of less than 3%, most of which is always fatal. Pancreatic ductal adenocarcinoma (pancreatic ductal adenocarcinoma) in the pancreatic cancer, which accounts for more than 90% of pancreatic cancer generally refers to pancreatic adenocarcinoma. Pancreatic adenocarcinoma is also called pancreatic adenocarcinoma, pancreatic adenocarcinoma, or pancreatic adenocarcinoma.

 Like many other malignant diseases, pancreatic cancer arises from the accumulation of acquired mutations. Multiple genetic and epigenetic changes, including activation of protocogenes, inactivation of tumor suppressor genes, and malformations of maintenance genes, may result in the development, sustained growth, and metastasis of pancreatic cancer. Related to Accumulated mutations in such genes are known to occur within predictable time during the "PanINs" (Pancreatic Intraepithelial Neoplsia) phase (Hruban et al. (2000) Clin Cancer Res 6: 2969-2972; Kern (2002) Cancer Biol Therapy 1: 607-613; Li et al. (2004) Lancet 363: 1049-1057). K-ras mutations occur about half of PanIN-1. The PanIN-2 stage is represented by additional changes and increases in the rate of K-ras mutations, and the appearance of multiple p16 malformations, and p53 protein family expression, which may indicate the presence of p53 mutations, sometimes occurs in more advanced PanINs. Loss of the tumor suppressor genes, TP53, DPC4 and BRCA2, appears to occur late in the development of pancreatic tumorigenesis, PanIN-3. Specifically, more than 85% of pancreatic adenocarcinomas have K-ras gene point mutations activated in pancreatic cancer development (Li et al. (2004) Lancet 363: 1049-1057; Xiong (2004) Cancer Chem Pharm 54: S69-77). K-ras mutations induce constitutive activation of Ras-Raf-MEK-ERK, an intracellular signaling pathway that induces cell proliferation and confers transgene properties on cells containing point mutations. Cause. Ras mutations are not associated with tumor stage or prognosis, and indicate that the K-ras oncogene may be involved in the onset of carcinogenesis but not in the likelihood or promotion of human pancreatic cancer. One of the major downstream targets of the ras family is phosphoinositol 3 kinase (PI3K). Activation of PI3K is associated with pancreatic cancer resistance to apotosis induced by chemotherapy or molecular drug targeting agents.

Pancreatic adenocarcinoma is one of the most deadly human malignancies with more than 30,000 deaths annually in the United States alone. At diagnosis these cancers are found in a state where only 10% to 15% can be excised due to the presence of locally advanced disease or distant metastasis. Recently, the most common treatment strategy for advanced pancreatic cancer is gemcitabine, a 2'-deoxycytidine nucleoside analog for intravenous administration that can induce apoptosis of human pancreatic cancer cells and inhibit tumor growth and progression. It is a treatment by. However, despite the best medical or surgical treatment, the results of treatment of patients with pancreatic adenocarcinoma are terrible, and as a group, the median survival of patients with this disease is 21 months or less. Thus, there is a need for clear, new and efficient treatment strategies to combat this deadly disease. As such, pancreatic cancer is a major health issue in developed countries and has a very poor prognosis (Faint et al. (2004) Datamonitor DMHC2045; Garcea et al. (2005) Pancreatology 5: 514-529; Kern et al. (2002). ) Cancer Biol Therapy 1: 607-613; Laheru and Jaffee (2005) Nature Rev Cancer 5: 59-467; Li et al. (2004) Lancet 363: 1049-1057). Despite excessive surgical and medical treatment, the mean life expectancy is about 15-18 months for patients with local disease and 3-6 months for patients with metastatic disease. Nearly 100% of patients with pancreatic cancer experience metastasis and die due to their unrestricted growth, which weakens metabolism, and less than 5% of patients who have not undergone resection survive a total of 5 years. Do. In addition, there is a problem that the initial diagnosis is difficult due to the non-specific initial symptoms. Currently, early detection of pancreatic cancer is still under development and not commercially available, and conventional cancer treatments have little effect on prognosis or disease outcome. Poor prognosis for pancreatic cancer is due to late manifestation, aggressive local invasion, early metastasis and insufficient response to chemotherapy.

The most common symptoms of pancreatic cancer include jaundice, abdominal pain and weight loss, and are not substantially special along with other emergence factors. Thus, diagnosing pancreatic cancer at an early stage of tumor growth is often difficult and requires a situation that includes considerable doubt and extensive diagnostic overhauls, often exploratory surgery. Endoscopic ultrasonography and computed tomography (CT) are the best noninvasive methods currently available for diagnosing pancreatic cancer. However, as well as differentiation of pancreatic cancer from lesioned pancreatitis, reliable detection of small tumors is difficult. Unfortunately, the majority of patients are currently diagnosed at a late stage where the tumor has already invaded the surrounding organs, extending outward and / or extensively metastasized (Gold et al., Crit. Rev. Oncology / Hematology, 39: 147-54 (2001). The disease is late detection is common, and early diagnosis of pancreatic cancer is rare in clinical settings.

Currently available treatment methods for pancreatic cancer do not cure the disease or reach a substantially improved survival time. Surgical resection is the only way to provide survival. However, due to tumor burden, only 10-25% of patients are targeted for 'curative resection'. In these patients undergoing resection treatment, the 5-year survival rate is still on average at around 10%.

On the other hand, a sense songhyang (Nardostachytis Rhizoma) is used as the root of a perennial plant of a sense songhyang (nardostachys Batalin chinensis) stomach pain, stomach cramps, thoracoabdominal coupon, neurogenic gastrointestinal disorders, vomiting, headache, or the like, respectively. Nardostachys jatamansi (NJ) has been used extensively as a tonic, irritant and anticonvulsant in several Asian countries, as well as to treat epilepsy, pathological excitement, palpitations and spasms (Bagchi, A., et al. , Planta Med., 57, 9697 (1991)). Various sesquiterpenes, lignans, and neolignans such as Jatamansic acid and Jatamansone are present in the roots (Chatterji, A, et al., National Institute of Science Communication, vol. 5, pp 99-100 (1997); Arora, RB., Indian Council of Medical Research, vol. 51 (1965)).

Perennial perennial persimmon roots include 1-aristol-2-one, nardostachone, 1,8,9,10-tetrad-hydroaristolan-2- components such as one) are contained. The self-acting effect of the sensational sensation relieves pain caused by abdominal pain and chest abdominal pain, and is also applied to neuropathic pain and headache. Wash each affected area by adding water to it. It acts on the central nervous system and has a calming effect, such as heel chogeun (尉 草根). In people with a constant heart rate, heart rate control is remarkable, and smooth muscle spasm of the bronchus, small intestine, large intestine, and uterus is released. Minor but also antibacterial. Because it is fragrant, it has the effect of false positive effect, so it can alleviate symptoms such as abdominal pain and loss of appetite caused by falsehood. It is also combined with all spices to make spices. The rooted water of the incense incense has been used for mental disorders, insomnia, blood disorders and circulatory disorders (Uniyal, MR., Et al., J. Res. Indian Med. 4, 83 (1969)), the main therapeutic component of the incense incense Is nardosinone that enhances neuronal activity and central nervous system (CNS) effects (Li, p. Et al., Journal of Pharmacology Science, 93, 122-125 (2003)). In addition, the extract of saengsam fragrance protects mice from thioacetamide induced liver damage (Bagchi, A., et al.). However, nothing has been disclosed or disclosed in the above literature in relation to pancreatic cancer-related diseases of S. aureus.
