Abstract

In this study, we report our contribution to the application of the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction for the synthesis of beta-keto-1,2,3-triazole derivatives 3a-f from ethinylestradiol and their application in the inhibition of two human cancer cells lines: human breast adenocarcinoma (MCF-7) and human hepatocellular carcinoma (HepG2). The beta-keto-1,2,3-triazole derivates 3a-f exhibited moderate cytotoxic activity for the HepG2 cells with IC50 values of 29.7 mu M (3a), 16.4 mu M (3b), 17.8 mu M (3c), 20.4 mu M (3d), 28.1 mu M (3e) and 28.2 mu M (3f). The semi-synthetic beta-keto-1,2,3-triazoles derivatives 3a-f were all characterized by FT-IR, NMR, HRMS and {[}alpha](D). (AU)
