Synthesis and biological evaluation of benzamide-chalcone hybrids as potential c-Met kinase and COX-2 inhibitors.

c-Met kinase and cyclooxygenase 2 (COX-2) enzymes are two significant targets in tumor progression. Chalcone and benzamide moieties were combined using molecular hybridization to assess their potential as c-Met kinase and COX-2 inhibitors. 4-Methylbenzamide and 4-chlorobenzamide chalcone analogs were synthesized, characterized, and evaluated for antiproliferative activity on Michigan Cancer Foundation-7 (MCF-7), HT-29, MDA-MB-231, COLO-205, and A549 cell lines by sulforhodamine-B stain (SRB) assay.
