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.

This study shows that melanoma-associated fibroblasts (MAFs) suppress cytotoxic T lymphocyte (CTL) activity and reveals a pivotal role played by arginase in this phenomenon. MAFs and normal dermal fibroblasts (DFs) were isolated from surgically resected melanomas and identified as Melan-A-/gp100-/FAP+ cells.
