H7278 NG-Hydroxy-L-arginine acetate salt Intermediate in the conversion of arginine to NO and citrulline by NO synthase.
I8021 L-N6-(1-Iminoethyl)lysine dihydrochloride Selective inhibitor of inducible nitric oxide synthase (iNOS).
N5501 Nω-Nitro-L-arginine ≥98% (TLC) Irreversible inhibitor of constitutive nitric oxide synthase (nNOS) and a reversible inhibitor of inducible nitric oxide synthase (iNOS).
N5751 Nω-Nitro-L-arginine methyl ester hydrochloride ≥98% (TLC), powder An analog of arginine that inhibits NO production. It has multiple effects on the vascular system. Inhibits relaxation induced by acetylcholine and induces an increase in arterial blood pressure. Abolishes lecithinized superoxide dismutase induced vasodilation when used to pretreat aortic ring preparations of mice. Induces leukocyte adhesion and increases microvascular fluid and protein fluxes and permeability. It has also been used in many studies of learning and memory.
