Description

Description générale

Cell permeable. L-Arginine analog that acts as a competitive inhibitor of all three isoforms of nitric oxide synthase (K_i = 700 nM for eNOS; K_i = 3.9 µM for iNOS; K_i = 650 nM for nNOS). Inhibits histamine- and acetylcholine-induced relaxation (K_i = 9.5 µM) of intact norepinephrine-constricted guinea pig pulmonary artery.
