A novel series of 1,5-and 1,8-disubstituted 10-benzylidene-10H-anthracen-9- ones and 10-(2-oxo-2-phenylethylidene)-10H-anthracen-9-ones was synthesized to assess the substituent effects on biological activity. The 3-hydroxy-2,4- dimethoxy-benzylidene analogue 16h displayed strong antiproliferative activity against several tumor cell lines,including multi-drug resistant phenotypes. Flow cytometric studies showed that KB/HeLa cells treated by elected compounds were arrested in the G2/M phases of the cell cycle. Among the compounds tested for inhibition of tubulin polymerization,14 compounds proved to be exceptionally active with IC50 values 1 mM. In the 1,5-dichloro-derived series of benzy-lideneanthracenones,E/Z isomers were separated and biological effects were monitored. We found that the olefinic geometry had no significant effect on biological activity. Furthermore,the E isomeric 1,5-dichloro-substituted phenacylidenes entirely proved to be more potent inhibitors of tubulin polymerization than the recently described 10-(2-oxo-2-phenylethylidene)-10H- anthracen-9-ones. In conclusion,the present study improves understanding of the action of anthracenone-based tubulin polymerization inhibitors and contributes to the design of further potent anti-tubulin drugs.
