| | L-Canavanine Usage And Synthesis |
| Uses | 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.
