nNOS inhibitor I is a cell-permeable, selective inhibitor of nNOS (Ki = 120 nM). It displays >2,500-fold and 320-fold selectivity over eNOS and iNOS, respectively. It has been used in a rabbit model for cerebral palsy to prevent hypoxia-ischemia-induced death and to reduce the number of newborn kits exhibiting signs of cerebral palsy.

Tyrosine phosphorylation of neuronal nitric oxide synthase (nNOS) during hypoxia in the cerebral cortex of newborn piglets: the role of nitric oxide
Neurosci Lett 2009 Oct 2;462(1):64-7.PMID:19560516DOI:10.1016/j.neulet.2009.06.075.
The present study aims to investigate the mechanism of activation of nNOS during hypoxia and tests the hypothesis that the hypoxia-induced increased tyrosine phosphorylation of nNOS in the cerebral cortical membranes of newborn piglets is mediated by nNOS-derived nitric oxide (NO). Fifteen newborn piglets were divided into normoxic (Nx, n=5), hypoxic (Hx, n=5) and hypoxic-pretreated with nNOS Inhibitor I (Hx-nNOSi) groups. Hypoxia was induced by an FiO(2) of 0.07 for 60 min. nNOS Inhibitor I (selectivity>2500 vs endothelial NOS and >500 vs inducible NOS) was administered (0.4 mg/kg, i.v.) 30 min prior to hypoxia. Cortical membranes were isolated and tyrosine phosphorylation of nNOS determined by Western blot. Membrane protein was immunoprecipitated with nNOS antibody, separated on 12% SDS-PAGE and blotted with anti-phosphotyrosine antibody. Protein bands were detected by enhanced chemiluminescence, analyzed by densitometry and expressed as absorbance (OD x mm(2)). Density (OD x mm(2)) of tyrosine phosphorylated nNOS was 51.66+/-14.11 in Nx, 118.39+/-14.17 in Hx (p<0.05 vs Nx) and 45.56+/-10.34 in Hx-nNOSi (p<0.05 vs Hx, p=NS vs Nx). The results demonstrate that pretreatment with nNOS inhibitor prevents the hypoxia-induced increased tyrosine phosphorylation of nNOS. We conclude that the mechanism of hypoxia-induced increased tyrosine phosphorylation of nNOS is mediated by nNOS-derived NO.
