Description:
IC50: 100 nM, 12 and 60 µM for nNOS, eNOS, and iNOS, respectively
Vinyl-L-NIO is a potent and selective inhibitor of nNOS.
Nitric oxide synthase (NOS) catalyzes the NADPH- and O2-dependent conversion of L-arginine to nitric oxide (NO) and citrulline. Three isoforms including the neuronal (nNOS), endothelial, and inducible have currently been identified. Since NO overproduction is able to contribute to various pathophysiological conditions, NOS inhibitors are considered as potential therapeutic agents.
In vitro: Vinyl-L-NIO was identified as a potent and selective inhibitor of nNOS. The Ki values for inhibition of nNOS, eNOS, and iNOS are 100 nM, 12 and 60 µM, respectively, as determined using initial rate measurements.
