Application

Nω-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

Nω-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).

Thiazolidinediones (also referred to as glitazones), agonists for Peroxisome Proliferator-Activated Receptor gamma (PPARγ), are used for treating type 2 diabetes mellitus, where they decrease insulin resistance and cardiovascular risk. Compounds bearing the thiazolidinedione structure have also been shown to inhibit
