Abstract

The invention discloses application of dioscin in preparing a drug-resistant osteosarcoma medicine. Drug-resistant osteosarcoma refers to an osteosarcoma cell line which has drug resistance to commonanti-tumor medicines, particularly U2OS tumor cells with drug resistance to methotrexate, doxorubicin and cis-platinum. Moreover, as a natural plant extract medicine, dioscin has wide application prospects in the field of anti-tumor medicine treatment.

Description

technical field [0001] The invention belongs to the field of medicaments, and in particular relates to the application of protodioscin in the preparation of drug-resistant bone tumor medicaments. Background technique [0002] Primary osteosarcoma is a common malignant bone tumor with onset mainly in adolescence. Because of its insidious onset and rapid progress, it is mostly in the middle and late stages when it is discovered. Therefore, the effect of surgery is poor, and radiotherapy and chemotherapy have obvious adverse reactions, resulting in poor quality of life and short survival period of osteosarcoma patients. There is an urgent need for effective and safe anticancer drugs for the treatment of osteosarcoma. [0003] Under normal physiological conditions, cell proliferation is strictly regulated, and cells can metabolize through programmed death, that is, apoptosis. However, when related molecular events such as activation of oncogenes, inactivation of tumor suppres...
