Abstract: | A 644-membered library of chalcones was prepared by parallel synthesis using the Claisen-Schmidt base-catalyzed aldol condensation of substituted acetophenones and benzaldehydes. The cytotoxicity of these chalcones was conveniently determined upon the crude products directly in 96-well microtiter test plates by the conventional MTT assay. This method revealed seven chalcones of IC(50) less than 1 microM of which 4'-hydroxy-2,4,6,3'-tetramethoxychalcone (5a) was the most active IC(50) (K562), 30 nM]; it causes cell cycle arrest at the G(2)/M point and binds to tubulin at the colchicine binding site. |
