Abstract
-chromen-3-yl)methylene]-3-phenylthiazolidin-4-one (3) through its reaction with a series of nitrogen and carbon nucleophiles under mild reaction conditions. The cytotoxic effects of all products were evaluated against three cancerous cell lines (MCF-7, HepG-2 and SKOV-3) by the standard SRB method. Fortunately, the products 7, 11, 12, 15, 19, 22, 26 and 28 were found to be the most active against all cancer cell lines, comparable to doxorubicin. Apoptosis was determined using flow cytometry along with cell cycle analysis and supported by molecular docking. The products 7, 11, 12, 15, 19, 22, 26 and 28 induced a significant early-and late-apoptotic effect against all tumor cells. In addition, these products preferred to arrest all cancer cells in the G1 and G2 phases. Finally, molecular docking was attempted to investigate the binding mode of products 12 and 22 with p53-MDM2 protein receptor.
