L-NAME is a nonselective inhibitor of nitric oxide synthetases (NOS) for nNOS (bovine), eNOS (human), and iNOS (murine), with Ki of 15 nM, 39 nM and 4.4 μM, respectively.


1400W 2HCl

1400W is a slow, tight binding, and highly selective inhibitor of inducible nitric-oxide synthase(iNOS).


Agmatine sulfate

Agmatine sulfate is a bioactive metabolite of the arginine amino acid. It has been shown to increase nitric oxide, reduce blood sugar levels and even increase growth hormone levels.


Aminoguanidine hydrochloride

Aminoguanidine is a diamine oxidase and nitric oxide synthase inhibitor. It acts to reduce levels of advanced glycation end products (AGEs) through interacting with 3-deoxyglucosone.



7-Nitroindazole, a heterocyclic compound, acts as a selective inhibitor for neuronal nitric oxide synthase showing a 10-fold selectivity for neuronal NOS.


L-Arginine HCl (L-Arg)

L-Arginine is the nitrogen donor for synthesis of nitric oxide, a potent vasodilator that is deficient during times of sickle cell crisis.
