Tegafur, as a raw material, reacted with chloroalkyl alcohols to give the intermediateN-hydroxyalkyl tegafur, then which reacted withp-toluenesulfonyl chloride to obtain tegafluoroalkyl sulfonate. A series of novel aryl (N3-tegafluoroalkyl) thio- and seleno-ether derivatives were efficiently synthesized by the reaction of tegafluoroalkyl sulfonate with diaryl disulfides or diselenides under binuclear titanium(IV) salophen perfluorobutanesulfonate/zinc catalytic system. Their structures of the target products were confirmed by1H NMR,13C NMR and HRMS. Their antitumor activities were evaluated by colorectal carcinoma HCT116 cells and gastric carcinoma SGC-7901 cells. The preliminary bioassay results showed that most target compounds had more antitumor activities than tegafur. Moreover, HCT116 cells staining experiments (DAPI) and quantitative determination by flow cytometry indicated that the growth inhibition was associated with the induction of apoptosis. In addition, organic sulfur (selenium) tegafur derivatives had lower toxicity than tegafur on human embryonic kidney HEK 293 cells.

Key words: tegafur, diaryl disulfides (diselenides), unsymmetrical sulfides (selenides), antitumor activity, apoptosis
