Biochem/physiol Actions

BEC (S-(2-boronoethyl)-l-cysteine) is a potent and specific arginase inhibitor that restores flow-induced responses in arterioles from diabetic rats.
BEC is a boronic analog of L-arginine, and L-cysteine. It competitively inhibits both arginase I and II. BEC does not directly affect nitric oxide synthase.
