Synthesis and in vitro evaluation of novel coumarin–chalcone hybrids as potential anticancer agents
摘要:
A series of coumarin-chalcone hybrids have been synthesized and evaluated for their in vitro cytotoxicity against a panel of four human cancer cell lines and normal fibroblasts (NIH3T3). Among 21 compounds screened, three compounds (23, 25 and 26) showed IC50 range from 3.59 to 8.12 mu M. The most promising compound 26 showed around 30-fold more selectivity towards C33A (cervical carcinoma) cells over normal fibroblast NIH3T3 cells with an IC50 value of 3.59 mu M.

In vitro and in vivo antifilarial activity evaluation of 3,6-epoxy [1,5]dioxocines: A new class of antifilarial agents
摘要:
A series of 3,6-epoxy [1,5] dioxocines were synthesized and evaluated for their antifilarial activity against adult parasites of human lymphatic filarial parasite Brugia malayi (sub-periodic strain) in vitro. Out of these, six compounds (4a-f) possessed improved in vitro anti-filarial activity and examples 4d and 4f were also found to be active in the in vivo experiments. These results demonstrate that 3,6-epoxy [1,5] dioxocines exhibits potent antifilarial activity and might be developed into a new class of antifilarial drug. (C) 2012 Elsevier Ltd.
