A Nitric Oxide Synthase inhibitor

ChEBI: An organic sulfate salt obtained by combining L-canavanine with one molar equivalent of sulfuric acid.

NO synthase inhibitor.

Canavanine is a naturally occurring?L-amino acid that competes and interferes with?L-arginine-utilizing enzymes due to its structural similarity with this?L-amino acid. It is a selective inhibitor of inducible nitric oxide synthase (iNOS). It acts as a substrate for arginyl tRNA and is incorporated during protein synthesis leading to aberrant canavanyl proteins. Supplementation with canavanine worsens the alfalfa induced Systemic lupus erythematosus (SLE) like syndrome and its incorporation with endosome and proteasome disrupts the antigen processing.

Store at -20°C

Recrystallise the sulfate by dissolving (~1g) in H2O (10mL), and adding with stirring 0.5 to 1.0 volumes of 95% EtOH whereby crystals separate. These are collected, washed with Me2CO/EtOH (1:1) and dried over P2O5 in a vacuum.
