L-NNA   

GtoPdb Ligand ID: 8759

Synonyms: compound 2 [PMID: 9667974] | nitroarginine
Compound class: Synthetic organic
Comment: L-NNA is an arginine analogue used as a biochemical tool in the study of nitric oxide and its biological effects. L-NNA inhibits the endothelial and neuronal isoforms of nitric oxide synthase (NOS), eNOS and nNOS respectively more potently than the inducible iNOS [1].
Selective nNOS inhibitors are being pursued for their potential to treat neurological disorders caused by excessive production of nitric oxide.
