Description:

BEC HCl is a slow-binding and competitive Arginase II inhibitor with Ki of 0.31 μM (ph 7.5).

In Vitro:

BEC HCl causes significant enhancement of NO-dependent smooth muscle relaxation in this tissue. [2] BEC HCl 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 lead to further increases in airways hyperresponsiveness. [3] In vivo: BEC HCl increased contractility in isolated myocytes from WT and NOS3 but not NOS1 knockout mice. [4]
