Discovery of 4-aryl-2-oxo-2H-chromenes as a new series of apoptosis inducers using a cell- and caspase-based high-throughput screening assay
چکیده انگلیسی

As a continuation of our efforts to discover and develop the apoptosis inducing 4-aryl-4H-chromenes as potential anticancer agents, we explored the removal of the chiral center at the 4-position and prepared a series of 4-aryl-2-oxo-2H-chromenes. It was found that, in general, removal of the chiral center and replacement of the 2-amino group with a 2-oxo group were tolerated and 4-aryl-2-oxo-2H-chromenes exhibited SAR similar to 4-aryl-2-amino-4H-chromenes. The 4-aryl-2-oxo-2H-chromenes with a N-methyl pyrrole fused at the 7,8-positions were highly active with compound 2a having an EC50 value of 13 nM in T47D cells. It was found that an OMe group was preferred at the 7-positon. 7-NMe2, 7-NH2, 7-Cl and 7,8 fused pyrido analogs all had low potency. These 4-aryl-2-oxo-2H-chromenes are a series of potent apoptosis inducers with potential advantage over the 4-aryl-2-amino-4H-chromenes series via elimination of the chiral center at the 4-position.

The synthesis and SAR of a group of apoptosis inducing 4-aryl-2-oxo-2H-chromenes with modifications at the 4-aryl, 7- and 8-positions is reported.Figure optionsDownload as PowerPoint slide
