Abstract

Combretastatin A-4 (CSA-4), a stilbene derivative, is a potent vascular disrupting agent (VDA) with the structural requirement of a cis-configuration to maintain a molecular geometry and a correct orientation of both phenyl groups. A series of indolic analogues of CSA-4 was synthesized by means of an efficient strategy. Six compounds (20b, 25b-27b, 32b, and 35b) were identified as potent inhibitors of tubulin polymerization and also displayed cytotoxic activities on B16 melanoma cells at a nanomolar level. Both activities were well correlated with the ability to induce morphological changes of EA.hy 926 endothelial cells. In conclusion, the cis-stilbene skeleton of CSA-4 could conveniently be replaced by the 3-aroylindolic moiety, thus avoiding any isomerization leading to inactive trans compounds.
