Synthesis and antitumor activity of epothilone B.

ABSTRACT

Epothilones are a class of 16-membered macrolide compounds targeting microtubules. They have good anticancer activity and their mechanism of action is similar to that of paclitaxel. Epothilones are also highly active against cancer cells that are resistant to paclitaxel and other anticancer drugs. They have good water solubility, simple structure, and are relatively easy to totally synthesize and or semi-synthesize. These results immediately attracted great interest and research enthusiasm from pharmaceutical companies and academia. Herein, the various synthetic methods of epothilone B and its anticancer activity were summarized and analyzed.
