Synthesis and biological evaluation of 4 beta-[(4-substituted)-1,2,3-triazol-1-yl]podophyllotoxins as potential anticancer agents

A series of novel 4 beta-[(4-substituted)-1,2,3-triazol-1-yl]podophyllotoxin derivatives were synthesized by employing Cu-1-catalyzed click chemistry and evaluated for their anticancer activity against a panel of seven human cancer cell lines (HT-29, HCT-15, 502713, HOP-62, A-549, MCF-7, and SF-295). The compounds 9b, 9c, 9c, 9f, and 9h showed significant cytotoxic activities especially against HT-29, HCT-15, 502713, cell lines.
