| L-CANALINE BASE Usage And Synthesis |
| Description | L-Canaline is an aminooxy analog of ornithine that irreversibly inhibits aminotransferases (transaminases), including ornithine aminotransferase (Ki = 2 μM). It forms oximes with α-keto acids and aldehydes, most notably with pyridoxal phosphate, an essential cofactor of aminotransferases. L-Canaline is naturally found in plants, including legumes, and is involved in the metabolism of L-canavanine, an aminooxy analog of arginine. It is cytotoxic to a range of organisms, including bacteria, insects, and parasites. | | Synthesis Reference(s) | Tetrahedron, 23, p. 4441, 1967 DOI: 10.1016/S0040-4020(01)88842-6 | | in vitro | canaline strongly inhibited the activity of pyridoxal-dependent enzymes, including amino acid decarboxylases, 5-hydroxytryptophan decarboxylase, aminotransferases, tyrosine aminotransferase, ornithine transcarbamylase and plasma diamino-oxidase. the canaline inhibition was due to complex formation between canaline and the pyridoxal coenzyme. l-canaline is one of the most potent inhibitors of pyridoxal enzymes. the ic50 value of l-canaline against ornithine aminotransferase was 3 ×10-6m [4]. | | in vivo | intraperitoneal administration of 500 mg of dl-canaline/kg body wt. only produced a transient inhibition of oat in brain and liver by 65-70%, suggesting that dl-canaline was not a useful tool in studies of biological consequences of oat inhibition.
