Description

technical field [0001] The present invention belongs to the technical field of medicines, in particular, it relates to epothilone analogues, a pharmaceutical composition for treating cancer or adjuvant treatment of tumors using it as an active ingredient, a preparation method thereof, and the preparation of the pharmaceutical compound and composition Application in anticancer or adjuvant anticancer drugs. Background technique [0002] The discovery of epothilone A and B was in the 1990s. Hofle and his colleagues first found a Sorangium cellulosum (Myxococcales) strain Soce90 from the soil on the banks of the Zambesi River in South Africa. A compound with antifungal activity was isolated from the plant and its properties were studied. Around 1995, Bollag et al. found that epothilone is a kind of pro-tubulin polymerization-promoting properties similar to p-glycotriol, which is strongly expressed in p-glycoprotein-expressing multidrug-resistant tumor cell lines. Antitumor act...
