Synthesis and antitumor activity evaluation of asiatic acid derivatives as survivin inhibitor

Abstract

A series of asiatic acid derivatives were synthesized and their cytotoxicities in vitro against two cancer cell lines (HepG2 and SGC7901) were evaluated by MTT assay. The results showed that compounds I₂, I₆, and II₆ have more potent anticancer activity than that of the positive control drug paclitaxel. The interactions between the compounds I₂, I₆, and II₆ and survivin were also studied by docking simulations.

Keywords:

• Asiatic acid derivatives
• anticancer activity
