Abstract

The invention relates to technical fields of traditional Chinese medicine active ingredient extraction and application. The astragaloside II has obvious inhibition effect on proliferation of two human liver cancer cells, namely BEL-7402 and BEL-7402 / 5-FU under the condition of different concentrations, and can be administrated with other medicines simultaneously or sequentially to achieve the anti-tumor effect. The invention provides an anti-tumor medicine with definite response relationship and corroborant structural components, lays a foundation for developing new clinical anti-tumor medicines, provides a medicine for reversing multidrug resistance to achieve the anti-tumor effect, and provides a new scheme for solving the problem of multidrug resistance of chemotherapeutics.

Description

technical field [0001] The invention relates to the technical field of extraction and application of active ingredients of traditional Chinese medicines. It specifically relates to the application of astragaloside II in the preparation of anti-liver cancer drugs. Background technique [0002] In a normal body, cell apoptosis and cell proliferation are always under strict regulation to maintain a dynamic balance. Once this balance is broken, it will lead to the occurrence of many diseases. Due to the decline in the function of apoptosis, mutant cells cannot be effectively cleared and accumulate to form tumor. Drugs that can induce apoptosis play an important role in tumor therapy. [0003] Multidrug resistance (Mtltidrug Resistance, MDR) is the appearance of cross-resistance to multiple chemotherapeutic drugs with different structures and functions after tumor cells are induced by one drug. The mechanism of tumor MDR is extremely complex, which is the result of the compreh...
