      Description
      OverviewSulfhydryl alkylating reagent that inhibits H+-ATPase and suppresses the short circuit current (IC50 = 22 µM) in pancreatic duct cells. Inactivates NADP-dependent isocitrate dehydrogenase. Also a potent inhibitor of both Mg2+ and Ca2+/Mg2+-stimulated DNA fragmentation in rat liver nuclei. Stimulates arachidonic acid release through activation of PLA2 in endothelial cells.
