Embodiment 1

[0031] Example 1 Inhibitory activity of the combination of toad venom and attenuated adjuvant extracts on the proliferation of various tumor cells

[0032] MTT method was used to detect the effects of toad venom and the combination of toad venom and different drugs on human gastric cancer cell MGC803, human liver cancer cell SMMC7721, human lung cancer cell A549, human leukemia cell HL-60, human cervical cancer cell SiHa, human ovarian cancer cell A2780, human breast cancer cell The effect on the proliferation of cancer cell MCF-7 and human prostate cancer cell PC-3. Dimethyl sulfoxide was used as the negative control group, and paclitaxel was used as the positive control group. The specific experimental results are shown in Table 1 and Table 2.

Embodiment 3

[0044] Example 3 Inhibitory effect of the composition of toad and Chinese medicine compound on H22 tumor-bearing mice

[0045] Take 60 mice and divide them into 6 groups, 10 in each group. Each mouse was inoculated with 0.2ml of H22 tumor-bearing dilution, and then given Chansu 25mg / kg, Chansu + Danggui Buxue Decoction 25+600mg / kg, Chansu + Renshen Shaoyao Decoction 25 + 1600mg / kg, Chansu + Shengmai Decoction 25 + 500mg / kg, Chansu + Fumai Decoction 25 + 1000mg / kg, after seven days of continuous administration, the mice were killed to strip off the H22 tumor-bearing mice in each group, The tumor weight was weighed, and the tumor inhibition rate was calculated. The specific experimental results are shown in Table 4.

Abstract

The invention provides a composition with anti-tumor effect and application thereof. The composition consists of 0.01 to 10 weight parts of pure bufadienolide compound, extract rich in bufadienolide compound, raw toad venom or toad skin and 0.01 to 99.9 weight parts of medicament with anti-arrhythmic effect. The composition with the anti-tumor effect has the advantage that the match among the components is scientific and reasonable; multiple in vitro tumor cytotoxicity and in vivo tumor inhibiting experiments show that the composition provided by the invention has good anti-tumor effect and plays a role in synergy after combination; and cardiotoxic experiments show that the cardiotoxicity of the composition provided by the invention is obviously reduced, and the composition can reduce the cardiotoxicity caused by primary single use of the bufadienolide compound, the toad venom or the toad skin and plays a role in detoxifying. Therefore, the composition is safer and more effective to use, and is expected to develop a new generation anti-cancer medicament.

Description

technical field [0001] The invention relates to a medicine, and specifically designs an antitumor composition with bufasteroids as active components and the application of the composition in preparing medicines for treating tumors. Background technique [0002] Malignant tumor is a disease with a high mortality rate. According to statistics, there are 2 million new cancer cases in my country every year, and 1.4 million deaths due to cancer. Among the 5 deaths of Chinese residents, 1 person died of cancer. At present, the main methods of tumor treatment include surgery, radiotherapy, chemotherapy, biological therapy, and endocrine therapy, etc., but Western medicine treatment has serious adverse reactions and is expensive. [0003] Toad Su, a traditional Chinese medicine, is a white slurry secreted by the back-auricular glands and skin glands of the bufo family Bufo bufo or black-orbited toad, which is processed and dried. Toad skin is the skin of Bufoidae animals, such as t...
