【 摘 要 】

Antiproliferative effects of 15 sulfides were investigated in human leukemia Jurkat cells. Treatment with 5-50 mu M of nine monosulfides and two linear disulfides did not induce DNA fragmentation. Whereas, furan-containing sulfur flavors including methyl 2-methyl-3-furyl disulfide (MMFDS), bis (2-methyl-3-furyl) disulfide (BMFDS), methyl furfuryl disulfide (MFDS) and difurfuryl disulfide (DFDS) induced DNA fragmentation to a varying extent in Jurkat cells. The cell viability-reduction effect of these sulfur flavors was in the following order: DFDS > BMFDS > MMFDS>>MFDS based on the IC50 values. MMFDS and BMFDS, but not DFDS, significantly increased the intracellular ROS level by 1.90- and 3.02-fold, respectively. Addition of N-acetylcysteine (NAC) or glutathione (GSH) partially suppressed induction of DNA fragmentation, apoptosis and caspase-3 activation by MMFDS and BMFDS. These results suggest that the furan-containing disulfides have a strong antiproliferative effect, and the oxidative stress and subsequent caspase-3 activation are involved in antiproliferative effect induced by MMFDS and BMFDS in Jurkat cells.
