Synthesis and Antitumor Activity of Novel 4-Chloro-3-Arylmaleimide Derivatives

A novel series of 4-chloro-3-arylmaleimide derivatives have been synthesized and evaluated for their cytotoxicity in vitro against human leukemia cell line and four human solid cancer cell lines. Most compounds showed high or mediate activity against the cancer cell lines when compared with bisindolylmaleimide. Among them, 4b is the most promising compound.
