摘要

Various 3-substituted 4-anilino-coumarin derivatives have been designed, synthesized and their anti-proliferative properties have been studied. The in vitro cytotoxicity screening was performed against MCF-7, HepG2, HCT116 and Panc-1 cancer cell lines by MIT assay. Most of the synthesized compounds exhibited comparable anti-proliferative activity to the positive control 5-Fluorouracil against these four tested cancer cell lines. Among the different substituents at C-3 position of coumarin scaffold, 3-trifluoroacetyl group showed the most promising results. Especially, compounds 33d (IC50 = 16.57, 5.45, 4.42 and 5.16 mu M) and 33e (IC50 = 20.14, 6.71, 4.62 and 5.62 mu M) showed excellent anti-proliferative activities on MCF-7, HepG2, HCf116 and Panc-1 cell lines respectively. In addition, cell cycle analysis and apoptosis activation revealed that 33d induced G2/M phase arrest and apoptosis in MCF-7 cells in a dose-dependent manner. Low toxicity of compounds 33d and 33e was observed against human umbilical vein endothelial cells (HUVECs), suggesting their acceptable safety profiles in normal cells. Furthermore, the results of in silico ADME studies indicated that both 33d and 33e exhibited good pharmacokinetic properties.
