n-ω-propyl-l-arginine

Nω-Propyl-L-arginine, a powerful and specific inhibitor of neuronal nitric oxide synthase (nNOS), effectively inhibits nNOS with a Ki of 57 nM. It exhibits a remarkable 149-fold selectivity for nNOS over endothelial NOS (eNOS).

Nω-Propyl-L-arginine hydrochloride is a highly selective and competitive neuronal nitric oxide synthase inhibitor with nanomolar affinity and marked selectivity over endothelial nitric oxide synthase, making Nω-Propyl-L-arginine hydrochloride a precise pharmacological tool for investigating nitric oxide signaling, neuronal regulation, and neurovascular function.
