NG-nitro-L-arginine  (Synonyms: Nω-nitro-L-arginine; L-NOARG; L-NG-Nitroarginine)

NG-nitro-L-arginine (Nω-nitro-L-arginine) is a NO Synthase inhibitor, with K_is of 0.61 μM (nNOS), 4.28 μM (iNOS), 0.72 μM (eNOS) respectively. NG-nitro-L-arginine inhibits endothelium-derived relaxing factor (EDRF) formation and release. NG-nitro-L-arginine inhibits portal-systemic shunting in portal-hypertensive rats, and increases blood pressure^[1][2][3][4].
