Description

TECHNICAL FIELD [0001] The present invention relates to a composition for treating pancreatic cancer,

The present invention relates to novel uses of non-extractables. Specifically, the present invention relates to a therapeutic composition and a cosmetic composition comprising as an active ingredient an extract of mugwort, which exhibits excellent prophylactic or therapeutic efficacy against pancreatic cancer.

Among the major diseases of modern people, studies on the methods of treatment and diagnosis of cancer are progressing relatively actively, focusing on lung cancer, liver cancer, stomach cancer which have high incidence. However, studies on esophageal cancer, colorectal cancer, and pancreatic cancer which have low incidence are relatively low.

The pancreas produces insulin that helps convert glucose into energy in the body and enzymes that help digest food in the body. 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 for men and women, respectively. Pancreatic cancer has a 5-year survival rate of less than 3%, and most are always fatal. Among pancreatic cancer, pancreatic ductal adenocarcinoma (pancreatic ductal adenocarcinoma) in the pancreatic duct accounts for more than 90%. Generally, pancreatic cancer refers to pancreatic ductal adenocarcinoma. Pancreatic duct adenocarcinoma is also called pancreatic adenocarcinoma, pancreatic adenocarcinoma or pancreatic ductal cancer.

 Like many other malignant diseases, pancreatic cancer arises from the accumulation of acquired mutations. Multiple genetic and epigenetic changes, including activation of protooncogenes, inactivation of tumor suppressor genes, and malformations of maintenance genes have been linked to the development, persistent growth, and metastasis of pancreatic cancer . Accumulated mutations in these genes are known to occur within a predictable period of time during the "PanINs" (Pancreatic Intraepithelial Neoplasia) phase (Hruban et al. (2000) Clin Cancer Res 6: 2969-2972; Kern et al. (2002) Cancer Biol Therapy 1: 607-613; Li et al. (2004) Lancet 363: 1049-1057). The mutation of K-ras occurs at about half of the PanIN-1. The PanIN-2 stage is indicated by an additional change and an increase in the K-ras mutation rate, and a plurality of p16 malformations, and p53 protein family expression, which may indicate the presence of p53 mutations, is occasionally seen in more advanced PanINs. Loss of tumor suppressor genes, TP53, DPC4 and BRCA2, appears to occur later in the development of pancreatic tumor formation, PanIN-3. Specifically, over 85% of pancreatic ductal adenocarcinomas have a K-ras gene point mutation activated in the development of pancreatic cancer (Li et al. (2004) Lancet 363: 1049-1057; Xiong Pharm 54: S69-77). The K-ras mutation induces cell proliferation and activates the constitutive elements of Ras-Raf-MEK-ERK, an intracellular signaling pathway that allows this gene to be transfected with cells containing point mutations. . The ras mutation is not associated with the tumor stage or prognosis and indicates that the K-ras oncogene may be involved in the onset of carcinogenesis but is not associated with the possibility or promotion of malignancy 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 apoptosis induced by chemotherapy or molecular drug targeting agents.

Pancreatic duct adenocarcinoma is one of the most deadly human malignant tumors in the United States, with more than 30,000 deaths annually. At the time of diagnosis, these cancers are found to be only able to be resected, with only 10% to 15% being due to the presence of locally advanced disease or distant metastasis. Recently, the most common treatment strategy for advanced pancreatic cancer is gemcitabine, an intravenous 2'-deoxycytidine neuroleoside analogue that can induce apoptosis of human pancreatic cancer cells and inhibit tumor growth and progression, Lt; / RTI > However, despite the best medical or surgical treatment, the outcome of patients with pancreatic ductal adenocarcinoma is dismal and as a group, the median survival of patients with this disease is less than 21 months. Therefore, clear, new and effective treatment strategies are needed to combat this fatal disease. Thus, 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. 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 average life expectancy is approximately 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 metastases and die due to their ability to weaken metabolism by their unrestrained growth, and the likelihood of survival for a total of five years without resection is only less than 5% Do. Also, there is a problem that early diagnosis is difficult due to initial symptoms that are not specific. Currently, early detection of pancreatic cancer is still under development and not commercially available, and conventional cancer therapy has little effect on prognosis or disease outcome. Poor prognosis of pancreatic cancer is due to late signs, aggressive local invasion, early metastasis and insufficient response to chemotherapy.

The most common symptoms of pancreatic cancer are jaundice, abdominal pain and weight loss, and are not really special with other adverse factors. Thus, in the early stages of tumor growth, diagnosing pancreatic cancer is usually difficult, and requires considerable suspicion and extensive diagnostic overcrowding, often involving exploratory surgery. Endoscopic ultrasonography and computed tomography (CT) are currently the best noninvasive methods available for the diagnosis of pancreatic cancer. However, definite detection of small tumors as well as differentiation of pancreatic cancer from lesion pancreatitis is difficult. Unfortunately, the majority of patients are now diagnosed at the terminal stage where the tumor has already invaded the surrounding organs and extended outside the caecum and / or at the extensively metastasized stage (Gold et al., Crit. Rev. Oncology / Hematology, 39: 147-54 (2001)). The disease is delayed detection is common, and 'early' pancreatic cancer diagnosis is rare in the clinical setting.

Current treatments that can be used for pancreatic cancer do not reach the healing or substantially improved survival time of the disease. Surgical resection is the only way to provide an opportunity for survival. However, due to tumor burden, only 10-25% of patients are targeted for 'curative resection'. In these patients who experience resection, the 5-year survival rate is still on the order of 10% on average.

On the other hand, Ulmi Pasta is fruit of Ulmus macrocarpa Hance, a deciduous tree, and is used for the treatment of analgesia, digestion, and antiparasitic. Mui is a dried medicine of ripe fruit of Ulmus macrocarpa belonging to elm family, and it is also called Mugo, Muiin, and Muuwu. It is also used for intestinal hemorrhoids, hemorrhoids, and malaria. In the early summer, the fruit is yellow, ripened yellow before it falls down, gathered for a few days, fermented and dried in the sun. The taste is spicy and the quality is fair. It is used as an insect repellent for tapeworms, and it is also used for intestinal hemorrhoids and hemorrhoids. Eat 5 ~ 9g a day or eat pills 가 powder and eat.

≪ Example 1 > Preparation of non-extractant

3 kg of mulberry (Chinese origin) purchased from Seoul Medicinal Plant were dried and crushed for 5 days at the shade and room temperature. The pulverized muayii was immersed in 30 L of 95% ethanol and extracted at 50 DEG C for 24 hours. This was filtered through a filter paper, dried and concentrated under reduced pressure at 45 ° C to obtain 437 g of a total extract, which was stored at -20 ° C.

<Example 2> Effect of non-extract extract on growth of pancreatic cancer cells

To investigate the effect of the extract of the extract of Example 1 on the growth of pancreatic cancer cells, Panc-1 cells, which are human pancreatic cancer cells, were treated with no-ethanol extract for 48 hours and analyzed by Alamar Blue. The Alamar Blue assay is a modified form of MTT assay that measures the fluorescence intensity of a product after degradation of a compound that is degraded by a specific enzyme into a living cell to determine the relative number of living cells after treatment It is an experimental method. This will be described in more detail below.

<2-1> Preparation and treatment of human pancreatic cancer cell line

Panc-1 cells, the pancreatic cancer cell line used in the present invention, were purchased from Korean Cell Line Bank (KCLB) and used for the experiment. Specifically, Panc-1 pancreatic cancer cells were cultured in Dulbeco's Modified Eagle's (DMEM) medium supplemented with 10% fetal bovine serum (Welgene) and 25 mM HEPES (4- (2-hydroxyethyl) -1-piperazineethanesulfonic acid) Medium) medium.

<2-2> Inhibition of Cell Growth of Panc-1 Pancreatic Cancer Cells

The effect of the extract of the present invention on the growth of Panc-1 cells, a pancreatic cancer cell, was confirmed. Specifically, 4.5 × 10 ³ Panc-1 pancreatic cancer cells per well were seeded on a 96-well plate and cultured for 24 hours. Then, the cells were cultured in DMSO (dimethyl sulfoxide) Ethanol extract was treated for 48 hours at a concentration of 0 to 100 μg / ml (specifically, 0, 3.125, 6.25, 12.5, 25, 50 and 100 μg / ml, respectively) (Table 1). After treating each concentration of the extract, 20 μl of Alamar Blue reagent was added to 0.2 ml of the cell culture solution filled in each well in a 96-well plate, and the plate was cultured in an incubator for 2 hours. The plate was gently shaken to react cells in each well, and the intensity of fluorescence was measured at 590 nm using a fluorescence photometer (Molecular Devices Corp.) while irradiating light at a wavelength of 544 nm. Survival rate is shown in Fig.

Moisture concentration Pancreatic cancer cell survival (average) Standard Deviation 0 [mu] g / ml 1,000 0.000 3.125 [mu] g / ml 0.958 0.036 6.25 [mu] g / ml 0.990 0.063 12.5 占 퐂 / ml 0.914 0.032 25 [mu] g / ml 0.711 0.050 50 [mu] g / ml 0.495 0.031 100 [mu] g / ml 0.176 0.020

As a result, as shown in Table 1 and FIG. 1, the growth of pancreatic cancer cells was decreased as the treatment concentration of mucus was higher, indicating that mucus had an effect of treating pancreatic cancer. In other words, it was 4.4% at 3.125 占 퐂 / ml, 1.0% at 6.25 占 퐂 / ml, 8.6% at 25 占 퐂 / ml, 28.9% at 50 占 퐂 / ml, 82.4% at 100 占 퐂 / Pancreatic cancer cells were killed. In addition, EC ₅₀ (half maximal effective concentration) was measured at 45.5 / / ml. In Table 1, the relative number of cells of pancreatic cancer cells after 48 hours was shown based on the number of survival rates of pancreatic cancer cells in the control group not treated with muoyi on the basis of 1, respectively. Thus, the non-extract extract of the present invention has excellent Panc-1 pancreatic cancer cell killing activity and further demonstrates that it has pancreatic cancer treatment and prevention activity.

&Lt; Example 3 > Acute toxicity test by extract

The mucus used in the present invention was widely used as a medicament and thus it was judged that there would be no problem in stability. However, toxicity test was conducted by oral administration and intraperitoneal administration to confirm this.

Acute toxicity tests were carried out using 6-week-old SPF SD rats. The extract of Example 1 of the present invention was suspended in 0.5% methylcellulose solution and administered to a 2-group animal at a dose of 5 g / kg in a single oral dose. After the administration of the test substance, the mortality, clinical symptoms, and weight changes of the animals were observed, and hematological tests and blood biochemical tests were carried out, and autopsy was performed to observe the abnormalities of the abdominal organs and thoracic organs.

As a result of the test, there were no clinically symptomatic or dead animals in all the animals to which the test substance was administered, and no toxic change was observed in weight change, blood test, blood biochemical test, and autopsy findings. As a result, all of the extracts showed no toxicity to 5 g / kg in rats, and the minimum LD ₅₀ (oral dose) was 5 g / kg or more.
