Abstract

A series of benzenesulfonamide derivatives were synthesized and evaluated for their anti-proliferative activity and interaction with tubulin. These new derivatives showed significant activities against cellular proliferative and tubulin polymerization. Compound BA-3b proved to be the most potent compound with IC50 value ranging from 0.007 to 0.036 μM against seven Cancer cell lines, and three drug-resistant Cancer cell lines, which indicated a promising anti-cancer agent. The target tubulin was also verified by dynamic tubulin polymerization assay and tubulin intensity assay.
