Descripción

General description

Sulfhydryl 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.

Sulfhydryl alkylating reagent. Has been used for blocking sulfhydryl containing reagents which interfere with glucose oxidase assays. Inactivates NADP-dependent isocitrate dehydrogenase. Endonuclease inhibitor. Also a potent inhibitor of both Mg²⁺ and Ca²⁺/Mg²⁺-stimulated DNA fragmentation in rat liver nuclei.
