A series of chalcones and respective flavonols have been synthesized to explore their anti-cancer activities. All the chalcones were synthesized by the reaction between aldehydes and substituted acetophenones in typical base carried Claisen-Schmidt condensation and their corresponding flavonols were synthesized by hydrogen peroxide oxidized Flynn-Algar-Oymada epoxidation and cyclization. The synthesized compounds were characterized by FTIR, 1H NMR, 13C NMR and Mass spectrometry and subjected for cytotoxicity test on MCF-7, HT-29 and HeLa cell lines. Maximum number of compounds demonstrated anti-proliferative activity with IC50 in the range of 18.67-174.3 μM. Compound 3h with a chloro group and 1-phenyl-3(4-methoxy phenyl)-4-pyrazolyl moiety and the flavonol 4a with 3-thienyl group were found to be most potent compounds among all the tested compounds against MCF-7 cell lines with IC50 18.67 and 23.79 μM respectively. The most active compound 3h also showed high docking score of -8.825.
