摘要

Chrysin (5,7-dihydroxylflavone, Chry) is a natural flavonoid extracted from plants and propolis. In this work, a novel chrysin-organotin (Chry-Sn) compound with enhanced anticancer activities was synthesized by the reaction of chrysin and triphenyltin chloride, and its potential anticancer effects against cancer cells were measured using various methods. Sulforhodamine B (SRB) results showed that chrysin and Chry-Sn had significant inhibition effects on the proliferation of MCF-7, A549 and HeLa human cancer cell lines in a dose-and time-dependent manner. These results suggested that Chry-Sn possessed enhanced anticancer effects. Hoechst 33258 staining and acridine orange staining results showed apoptosis and nuclei fragments significantly increased after being treated with chrysin and Chry-Sn respectively. Moreover, chrysin and Chry-Sn significantly increased ROS levels in MCF-7 cells. Western blot results showed that chrysin and Chry-Sn activated caspase 3 and induced autophagy by increasing LC3-II level. All results showed collectively that Chry-Sn could be a more promising drug than chrysin in anticancer treatment.
