introduction of S-(2 Boronorthyl) L-Cysteine HCL [BEC]
BEC, Hydrochloride is a boronic acid-based arginine analog that acts as a slow-binding, competitive transition state inhibitor of arginase I and II (Ki = 310 nM for human recombinant type II arginase, pH 7.5). BEC does not inhibit nitric oxide synthase (NOS), it causes significant enhancement of NO-dependent smooth muscle relaxation in human penile corpus cavernosum tissue.
