A series of N-(aminosulfonyl)-4-podophyllotoxin carbamates were synthesized via the Burgess-type intermediate, and their antiproliferative activities were evaluated. Most of them possessed more potent cytotoxic effects against four human tumor cell lines (HeLa, A-549, HCT-8 and HepG2) and less toxic to normal human fetal lung fibroblast WI-38 cells than etoposide. In particular, N-(morpholinosulfonyl)-4-podophyllotoxin carbamate (9) exhibited the most potent activity towards these four tumor cells with IC50 values in the range of 0.5-16.5μM. Furthermore, immunofluorescence analysis revealed that 9 induced cell apoptosis by up-regulating the expression of p53 and ROS. Meanwhile, 9 effectively inhibited tubulin polymerization and microtubule assembly at cellular levels in HeLa cells. In addition, 9 could induce cell cycle arrest in the G2/M phase in HeLa cells by up-regulating levels of cyclinB1 and cdc2 and decreasing the expression of p-cdc2. These results indicated that 9 had potential for further development as anticancer agents.
