Synthesis and antiproliferative activity of novel 4-substituted-phenoxy-benzamide derivatives

A series of novel 4-substituted-phenoxy-benzamide derivatives bearing an aryl cycloaliphatic amine moiety were synthesized and evaluated for antiproliferative activity against SW620, HT29 and MGC803 cancer cell lines in vitro. The pharmacological data demonstrated that the majority of target compounds exhibited moderate efficacy in HT29 and MGC803 cell lines. Compound 10c showed promising inhibition of hedgehog (Hh) signaling pathway in an Hh-related assay. In addition, the superposition pattern of 10c showed a good fit for a pharmacophoric model generated by Hh inhibitors and provided a basis for further structural optimization.

A series of 4-substituted-phenoxy-benzamide derivatives bearing an aryl cycloaliphatic amine moiety were synthesized and evaluated for their antiproliferative activity. Three compounds were further examined for their hedgehog pathway inhibition.Figure optionsDownload as PowerPoint slide
