Product Name :
BEC HCl
Description:
BEC, also known as S-(2-boronoethyl)-L-cysteine, is an a slow-binding and competitive Arginase II inhibitor with Ki of 0.31 μM (ph 7.5). BEC significantly enhances NO-dependent relaxation of human penile corpus canvernosum smooth muscle in vitro at concentrations between 0.1-1.0 mM. S-(2-boronoethyl)-L-cysteine binds to arginase as a transition state analogue and enhances smooth muscle relaxation in human penile corpus cavernosum.

The structure of the complex reveals that the boronic acid moiety undergoes nucleophilic attack by metal-bridging hydroxide ion to yield a tetrahedral boronate anion that bridges the binuclear manganese cluster, thereby mimicking the tetrahedral intermediate (and its flanking transition states) in the arginine hydrolysis reaction.|In Vivo:|Administration of the arginase inhibitor BEC decreases arginase activity and causes alterations in NO homeostasis, which are reflected by increases in S-nitrosylated and nitrated proteins in the lungs from inflamed mice. BEC enhances perivascular and peribronchiolar lung inflammation, mucus metaplasia, NF-κB DNA binding, and mRNA expression of the NF-κB-driven chemokine genes CCL20 and KC, and leads to further increases in airways hyperresponsiveness.|References:|Kim NN, Cox JD, Baggio RF, Emig FA, Mistry SK, Harper SL, Speicher DW, Morris SM Jr, Ash DE, Traish A, Christianson DW.
