Novel series of 7-substituted-benzopyran-2-ones was synthesized by incorporating heterocyclic rings as oxadiazole, triazole, pyrazole or pyrazolin-5-one to benzopyran-2-one nucleus at p-7 via methylene-oxy or acetoxy linker. In-vitro anticancer activity was evaluated for these hybrids; twelve compounds were selected by National Cancer Institute for anticancer screening. Among them, compound 9a exhibited broad spectrum antitumor activity showing full panel median growth inhibition (GI(50)) = 5.46 mu M. According to docking results using Molsoft ICM 3.4-8c program, the target compounds may act through inhibition of topoismerase 1, where camptothecin is used as ligand. (C) 2010 Elsevier Masson SAS.
