Design, synthesis and anticancer screening of 3-(3-(substituted phenyl) acryloyl)-2H-chromen-2ones as selective anti-breast cancer agent.

By utilizing concept of molecular hybridization, involving combination of various Pharmacophore, novel substituted coumarin-chalcone hybrids was synthesized and evaluated for anti-proliferative activity against estrogen receptor-positive MCF-7 and negative MDA-MB-435 breast cancer cell lines. In-vivo study was carried out by N-methyl nitrosourea (MNU) induced mammary carcinoma in virgin female Spraque Dawly (SD) rats. The compound 5b has highest potential than standard drug Adriamycin, comparable against Tamoxifen against ER-positive MCF-7 breast cancer cell lines. Docking study was performed to study the binding orientation and affinity of synthesized compounds on the ER-α enzyme.
