Embodiment 1

[0046] (1) Dilute baicalein and 10-hydroxycamptothecin with the DMEM high-sugar culture medium containing 10% fetal bovine serum, 100kU / L penicillin, and 100mg / L streptomycin respectively to be the concentrations of Table 1~3, different The experimental results of the inhibitory effect on MCF7 proliferation when the concentration of baicalein and 10-hydroxycamptothecin are used alone are shown in figure 1 And Table 1 and Table 2.

[0051]

[0052] Taking Table 1 as an example for calculation and description, first obtain the survival rate of baicalein acting on MCF7 cells, and then perform fitting according to the relationship between the dosage and the cell survival rate to obtain the equation Y=4.96X-9.81, then b= 4.96, a=-9...

Embodiment 2

[0072] (1) Dilute baicalein and 10-hydroxycamptothecin with the DMEM high-glucose medium containing 10% fetal bovine serum, 100kU / L penicillin, and 100mg / L streptomycin respectively to be the concentrations of Table 4-6, different concentrations The experimental results of the inhibitory effect of baicalein and 10-hydroxycamptothecin on the proliferation of BGC823 can be found in image 3 And Table 4 and Table 5.

Abstract

The invention relates to a medicine composition which contains 10-hydroxycamptothecine and baicalein. The medicine composition has obvious synergetic effects on treating stomach cancer, breast cancer, liver cancer and the like, reduces the dose of the medicine, improves the curative effect of the medicine, and reduces the generation of side effects.

Description

technical field [0001] The present invention relates to an antitumor pharmaceutical composition, in particular to a pharmaceutical composition of baicalein and 10-hydroxycamptothecin and its preparation for treating lung cancer, pancreatic cancer, colon cancer, liver cancer, prostate cancer, kidney cancer, gastric cancer, brain cancer, etc. Use in drugs for tumors, sarcomas, ovarian or breast cancer. Background technique [0002] Cancer is one of the major diseases threatening human health. According to the World Health Organization, cancer has caused 7.6 million deaths in 2008 (accounting for about 13% of all deaths), and the number of deaths will continue to rise, and it is expected to exceed 13.1 million by 2030. Furthermore, most cancer deaths are caused by cancers of the lung, stomach, liver, colon and breast. Currently, there are three main methods for cancer treatment, namely surgery, radiotherapy and chemotherapy, among which chemotherapy is the main method. Howev...
