Nitric oxide synthases (NOSs) are a family of enzymes catalyzing the production of nitric oxide (NO) from L-arginine. NO synthases catalyze the oxidation of L-arginine to NO and L-citrulline. Mammals contain three NOS isoforms: neuronal NOS (nNOS), inducible NOS (iNOS), and endothelial NOS (eNOS). NO produced from these different NOS isoforms is involved in a wide range of physiologic functions in the nervous, immune, and cardiovascular systems. Unregulated NO production can lead to pathologic conditions such as stroke, inflammation, and hypertension. Therefore, the control of NOS activity by isoform selective NOS inhibitors has great potential for therapeutic treatments of NO-related diseases.
