Product does not compete with ATP.

Target IC₅₀: 500 nM against endothelial nitric oxide synthase (eNOS); 2 µM against acetylcholine-induced relaxation of rat aorta rings; EC50 = 19.5 mg/kg for a dose-dependent increase in mean arterial blood pressure in the rat

Primary TargeteNOS

Cell permeable: yes

General description

A cell-permeable, more potent inhibitor of endothelial nitric oxide synthase (eNOS; IC₅₀ = 500 nM) compared to other arginine analogs such as L-NAME (Cat. No. 483125) and L-NMMA (Cat. No. 475886). Inhibits acetylcholine-induced relaxation of rat aorta rings (IC₅₀ = 2 µM) and causes a dose-dependent increase in mean arterial blood pressure in the rat (EC₅₀ = 19.5 mg/kg).

Cell permeable. Approximately five times more potent as an inhibitor of endothelial nitric oxide synthase (IC₅₀ = 500 nM) than other arginine analogs, such as L-NAME (Cat. No. 483125) and L-NMMA (Cat. No. 475886). Inhibits acetylcholine induced relaxation of rat aorta rings (IC₅₀ = 2 µM) and causes a dose-dependent increase in mean arterial blood pressure in the rat (EC₅₀ = 19.5 mg/kg).
