Abstract

Different alkyl amide (15a-l) and alkyl amine (16a-e) derivatives of 7,8-dimethoxy-3-hydroxy-2-(4-methoxyphenyl)benzopyran-4-one were synthesized and evaluated for their Anticancer activity against five different Cancer cell lines using SRB assay. Compounds 15e, 15i, 15j and 16a-e showed significant Anticancer activity within the range of IC50 2.58-34.86μM. The most promising molecule, 16c, was further analyzed for its effect on cell cycle and Apoptosis of Estrogen receptor positive Cancer cells (MCF-7 cells) which showed that 16c triggered Apoptosis in MCF-7 cells and arrested cells population at sub-G0 (apoptotic) and G2M phase. In tubulin polymerization assay, 16c interfered with kinetics of tubulin polymerization.
