Nω-Methyl-L-arginine monoacetate

Competitively inhibits the generation of NO from arginine and is a useful tool for inhibition of NO mediated effects. In vitro, L-NMMA inhibits relaxation of rat aorta rings induced by acetylcholine (IC50=9.5µM). In vivo, it causes a dose dependent increase in mean arterial blood pressure in anesthetized rats (EC50=16.7mg/kg).
