Synthesis and evaluation of novel benzophenone-thiazole derivatives as potent VEGF-A inhibitors.

A series of 2-(4-benzoyl-phenoxy)-N-(4-phenyl-thiazol-2-yl)-acetamides (10a-n) were synthesized by multistep reaction sequence and all the compounds were well characterized for structural elucidation. The in vitro cytotoxicity of compounds 10a-n was evaluated against EAC and DLA cell lines using trypan blue dye exclusion method. Further MTT assay and LDH release assay, followed by in vivo studies on murine model were also evaluated. The compound 10h with a methyl and fluoro groups at benzophenone moiety and methoxy group at phenyl ring was in a leading position to exhibit the promising antiproliferative effect through translational VEGF-A inhibition.
