Background

K(I): 0.4-0.6 microM

S-(2-boronoethyl)-L-cysteine (BEC) is an arginase inhibitor.

Arginases can catalyze the hydrolysis of L-arginine to yield L-ornithine and urea. Recently, studies show that arginases, both the type I and type II isozymes, involve in the regulation of nitric oxide production via modulating the availability of arginine for nitric oxide synthase.

In vitro: Although BEC has been first identified as inhibitor of type I arginase, it was found to be a classical, competitive inhibitor of human type II arginase with K(i) value 0.31 microM at pH 7.5. However, at pH 9.5, BEC was a slow-binding inhibitor of the enzyme with K(i) value 30 nM [1].

In vivo: In animal study, the administration of BEC was found to be able to decrease arginase activity and cause alterations in NO homeostasis, which were indicated by increases in S-nitrosylated and nitrated proteins in the lungs from inflamed mice. Moreover, in contrast to first expectations, BEC could enhance perivascular and peribronchiolar lung inflammation, NF-κB DNA binding, mucus metaplasia, and mRNA expression of the NF-κB-driven chemokine genes including KC and CCL20, and result in further increases in airways hyperresponsiveness [2].

Clinical trial: Up to now, BEC is still in the preclinical development stage.
