We describe the synthesis and biological evaluation of a series of diarylmethyloxime and diarylmethylhydrazone analogues that contain an indole ring and different modi. cations on the nitrogen of the bridge. Several compounds showed potent tubulin polymerization inhibitory action as well as cytotoxic activity against cancer cell lines. The N-methyl-5-indolyl substituted analogues are more potent than ethyl substituted ones. The most potent inhibitors of tubulin polymerization are the diarylketones and the diaryloximes. The cytotoxicity against several cancer cell lines is lower for the oximes than for the ketones. Other substitutions on the imine nitrogen greatly reduce the tubulin inhibitory and/or cytotoxic potencies. (C) 2008 Elsevier Ltd. All rights reserved.
