Descripción

Application

N_ω-Nitro-L-arginine has been used:

• as nitric oxide synthase (NOS) inhibitor, to measure the release of nitric oxide (NO) derivatives in cytochrome c reduction assay
• to pretreat fiber bundles for contractile studies
• as NOS inhibitor to characterize the generation of NO in Taxus yunnanensis cells
• as an irreversible inhibitor of the neuronal NO synthase (nNOS) to preincubate swimbladder preparations

Biochem/physiol Actions

N_ω-Nitro-L-arginine/L-NNA helps to reduce the levels of cortical hyperemia and brain cGMP occurring due to hypercapnia.

Irreversible inhibitor of constitutive nitric oxide synthase (nNOS) and a reversible inhibitor of inducible nitric oxide synthase (iNOS).
