Design, synthesis and anticancer activity of matrine-1H-1,2,3-triazole-chalcone conjugates

A series of novel matrine-1H-1,2,3-triazole-chalcone conjugates was synthesized and their anticancer activity against A549, Bel-7402, Hela, and MCF-7 cancer cells was evaluated. Most of the conjugates displayed higher potency than their components. Compounds 6h and 6i exhibited more potent anticancer activity than 5-fluorouracil against the four tested human cancer cell lines and lower cytotoxicity to NIH3T3 normal cells. Flow cytometry tests demonstrated that compound 6h could induce apoptosis of A549 cells in a concentration-dependent manner. Moreover, 6h could efficiently suppress human tumor growth in mouse xenograft model without causing obvious toxicities. (C) 2015 Elsevier Ltd. All rights reserved.
