N-OMEGA-PROPYL-L-ARGININE

Description

N^ω-Propyl-L-Arginine is a potent and selective inhibitor of neuronal nitric oxide synthase (nNOS). N^ω-Propyl-L-Arginine is a competitive inhibitor of bovine nNOS having a K_i value of 57 nM. The K_i values for eNOS (bovine) and iNOS (murine) are 8.5 and 180 μM, respectively. N^ω-propyl-L-Arginine therefore exhibits 3,000-fold and 150-fold selectivity for the neuronal isoform versus the inducible (murine) and endothelial (bovine) isoforms of NOS, respectively.
