Application of verbascoside in preparation of medicines
Technical Field
The invention relates to application of verbascoside in preparation of a medicament.
Background
Primary liver cancer mainly refers to hepatocellular carcinoma (HCC), which is the 5 th most common cancer worldwide; the risk factors include chronic Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) infection, autoimmune hepatitis, long-term drinking, obesity, diabetes, etc. Primary liver cancer is highly malignant, difficult to diagnose early and has poor prognosis. In China, the incidence of liver cancer is increased by 1% per year on average, but the survival rate is still low. According to a Barcelona Clinical Liver Cancer (BCLC) staging system, radical treatment (including surgical resection, liver transplantation and local ablation treatment) can be carried out on a liver cancer patient with no symptoms at an extremely early stage and an early stage (both the A stage); but most patients have a chance of therapeutic surgical treatment at an advanced stage when the diagnosis is confirmed for the first time, and the recurrence rate exceeds 70% within 5 years at the risk of recurrence. Orthotopic liver transplantation is considered as the ultimate treatment for liver cancer because it can eliminate not only malignant tumors but also the entire diseased liver, however, due to the availability of liver resources and its difficulties, the number of patients whose liver transplantation surgery is affordable is far less than that of patients who are surgically resected. Local ablation therapy is usually performed by radiofrequency ablation or percutaneous injection of ethanol for the treatment of small tumors < 3cm in diameter. Transcatheter arterial catheterization chemoembolization (TACE) is a local treatment for asymptomatic, multinodular (mid-clinical or BCLC phase B) liver cancer patients. The whole-body treatment of liver cancer comprises radiotherapy, chemotherapy, gene therapy, immunotherapy and the like, and the methods can improve the life quality of patients to a certain extent and prolong the life cycle of the patients. Molecularly targeted drugs such as sorafenib (sorafenib) and regorafenib (regorafenib) are recommended treatment methods for patients with advanced clinical (BCLC C-stage) liver cancer (with invasive or extrahepatic tumors), but the effective rate is still less than 50%, and half of patients need to bear adverse drug reactions and huge economic burden and also need to face final drug tolerance risk. Based on the above severe situation, researchers need to pay attention to new intervention targets and develop more effective drugs and treatment strategies for treating liver cancer with less adverse reactions.
Acteoside (A01) is a kind of phenylethanoid glycosides, widely exists in various medicinal plants such as flos Caryophylli, herba plantaginis, and Cistanchis herba, and has multiple physiological activities of resisting oxidation, resisting inflammation, killing bacteria, and regulating apoptosis. Previous studies have demonstrated that a01 has effects of inhibiting prostate cancer cell proliferation, enhancing colorectal cancer cell sensitivity to chemotherapeutic drugs, and inhibiting tumor growth in (melanoma) -bearing mice. However, a role of a01 in hepatocellular carcinoma has been rarely reported. Only one Master thesis (research on antitumor activity of baicalin metal complex and echinacoside, verbascoside, university of Tarim) mentions that verbascoside has a bidirectional effect on cell proliferation of hepatocarcinoma cell SMMC-7221, i.e., the effect of promoting cell proliferation at low dose and the effect of inhibiting cell proliferation at high dose. However, it is clear that a single positive screening result (i.e. inhibition of cell proliferation) of a test substance at the cellular level does not naturally confer/suggest the property of the test substance to have an anti-tumor effect; indeed, screening of effective compounds at the cellular level has not demonstrated efficacy in animal models (screening of novel compounds for antitumor activity, king, et al, proceedings of the eleventh chinese co-annual meeting, 2009/9/1).
Furthermore, chemopregention of Colon Carcinogenesis by Dietary Alcohol, CANCER RESEARCH 57.420-425 and Phase II Trial of Perilliyl Alcohol in Patients with Metastic color CANCER, International Journal of gastric CANCER, vol.32, No. 2-3, 125-128 indicate that Perillyl Alcohol can significantly inhibit Colon invasive adenocarcinoma, but oral administration of Perillyl Alcohol to Patients with advanced Colorectal CANCER does not have clinical anti-tumor activity. That is, some drugs are active on animal cancer cells, but not on human cancer cells.
Folic Acid (FA) can prevent the occurrence of colorectal cancer in mice induced by 1, 2-Dimethylhydrazine (DMH) (Lu R et al, Folic acid and sodium butyl predictive in a mouse model of colorectal cancer. epitopes 2008, Vol3(6): 330-. That is, some drugs have a cancer-preventing effect, but not necessarily a cancer-treating effect.

The major diameter a (mm) and the perpendicular minor diameter b (mm) of the tumor are measured by a digital display electronic caliper 2 times a week from the administration, and the tumor volume is calculated by the following formula: TV ═ ab2The relative tumor volume calculation formula is: the resulting tumor volume was measured at caging (i.e., d1) for RTV versus Vo, Vt being the tumor volume at each measurement. Animals were sacrificed 32 days after inoculation (d22)Weighing, dissecting and taking tumor mass, weighing tumor weight, and judging the result according to the following formula:
tumor inhibition (%) - (control mean RTV-administration mean RTV)/control mean RTV × 100%.

The major diameter a (mm) and the perpendicular minor diameter b (mm) of the tumor are measured by a digital display electronic caliper 2 times a week from the administration, and the tumor volume is calculated by the following formula: TV ═ ab2The relative tumor volume calculation formula is: the resulting tumor volume was measured at caging (i.e., d1) for RTV versus Vo, Vt being the tumor volume at each measurement. Animals were sacrificed 21 days after inoculation (d14), weighed, tumor masses dissected, and tumor weights were weighed, and the results were determined according to the following formula:
tumor inhibition (%) - (control mean RTV-administration mean RTV)/control mean RTV × 100%.
1.4 technical effects
1.4.1 Bel7404 nude mouse transplantation tumor model
After nude mice are continuously administrated for 22 days, the tumor inhibition rates of the A01 medium dose group (25mg/kg), the A01 high dose group (50mg/kg), the A01 intravenous administration group (20mg/kg), the sorafenib group and the A01+ sorafenib group are respectively 37.2%, 39.8%, 33.4%, 21.1% and 45.7% (P values are all less than 0.01, and a two-factor analysis of variance method is adopted for comparison among experimental data groups, and P <0.05 is taken as a statistical significance), so that verbascoside has an obvious inhibition effect on human hepatoma cell Bel7404 transplantable tumor.
1.4.2 JHH-7 nude mouse transplantation tumor model
After the nude mice are continuously administrated for 14 days, the tumor inhibition rates of the A01 group, the A01+ sorafenib group and the sorafenib group are respectively 54.7%, 69.4% and 50.8% (P values are all less than 0.01, and P <0.05 is statistically significant by adopting a two-factor anova method in comparison among experimental data groups), which indicates that verbascoside has obvious inhibition effect on human hepatoma cell JHH-7 transplanted tumor.
In conclusion, verbascoside has obvious inhibition effect on the growth of human liver cancer nude mouse transplanted tumor (Bel7404 tumor bearing nude mouse or JHH-7 tumor bearing nude mouse), has obvious difference compared with a model group, and can be applied to treating liver cell liver cancer. Has important research value and application prospect for treating the hepatocellular carcinoma.
