NO synthase inhibitor | [Definition]
ChEBI: A non-proteinogenicL-alpha-amino acid that is L-homoserine substituted at oxygen with a guanidino (carbamimidamido) group. Although structurally related to L-arginine, it is non-proteinoge
ic. | [Biochem/physiol Actions]
Canavanine is a naturally occurring L-amino acid that interferes with L-arginine-utilizing enzymes due to its structural similarity. It is a selective inhibitor of inducible nitric oxide synthase (iNOS). Overproduction of NO by iNOS plays a crucial role in the pathophysiology of septic shock and chronic inflammation. | [Purification Methods]
Crystallise S-canavanine from absolute EtOH or aqueous EtOH.
