L-Arginine (hydrochloride)

L-Arginine is an amino acid and precursor of nitric oxide (NO). L-Arginine is a substrate for NO synthase that is oxidized to form NO and L-citrulline. It enhances NO release in porcine aortic endothelial cells treated with bradykinin (Cay-37408) or A23187 (Cay-11016). L-Arginine (30 and 300 mg/kg, i.v.) induces dilation of pial arterioles and increases cerebral blood flow in normotensive and spontaneously hypertensive rats. It also reduces infarct size by 35 and 28% in normotensive and spontaneously hypertensive rats, respectively, following middle cerebral artery occlusion.Formal Name: L-arginine, monohydrochloride.
