BEC·HCl 生物活性

描述 BEC hydrochloride is a slow-binding and competitive Arginase II inhibitor with Ki of 0.31 μM and 30 nM at pH 7.5 and pH 9.5, respectively[3]. Administration of the arginase inhibitor BEC (S-(2-boronoethyl)-l-cysteine) decreased arginase activity and caused alterations in NO homeostasis, which were reflected by increases in S-nitrosylated and nitrated proteins in the lungs from inflamed mice. BEC enhanced perivascular and peribronchiolar lung inflammation, mucus metaplasia, NF-kappaB DNA binding, and mRNA expression of the NF-kappaB-driven chemokine genes CCL20 and KC, and lead to further increases in airways hyperresponsiveness[4]. BEC is associated with a decline in FEV1(forced expiratory volume in 1 second), and a consistently high BEC is an independent risk factor for an accelerated decline in FEV1[5].
