of anticancer drugs with specific targets is of prime importance in modern chemical biology. Observing the importance of benzophenone and coumarin nucleus, it would be worthwhile to design and synthesize novel benzophenone derivatives (8a–o) bearing the coumarin nucleus. Further, they were screened for prospective anticancer activities in vitro against the Michigan Cancer Foundation‐7 (MCF‐7) and Ehrlich's

A series of 2,5-di(4-aryloylaryloxymethyl)-1,3,4-oxadiazoles 9a-j were obtained via multistep synthesis from hydroxybenzophenones 4a-e. The cytotoxicity of compounds 9a-j was evaluated against human leukemia cell lilies (K562 and CEM). The compounds exhibited moderate to good anti-cancer activity with compounds 9b and 9i having a chloro group exhibiting the best activity (IC50 = 10 mu M). Compound 9i exhibited activity against both the cell lines and 9b only exhibited activity against CEM. Further, a lactate dehydrogenase (LDH) assay and DNA fragmentation studies of the compounds 9a-j were also performed. (C) 2013 Elsevier Masson SAS. All rights reserved.

benzophenone analogs (9a–d and 10a–d) substituted with methyl, chloro and fluoro groups at different positions on an identical chemical backbone and incorporating variations in the number of substituents have been synthesized in a multistep process and characterized. In this study, we further evaluate the newly synthesized compounds for their cytotoxic and anti-proliferative effects against A549, HeLa and MCF-7

against DLA cells by in vitro and in vivo studies. The results suggested that, compounds 8b with fluoro group and 8e with chloro substituent at the benzoyl ring of benzophenone scaffold as well as pyridine ring with hydroxy group exhibited significant activity. Further investigation in mouse model suggests that compounds 8b and 8e have the potency to activate caspase activated DNase (endonuclease) which
