L-ABRINE Usage And Synthesis

Chemical Properties

white to light grey crystalline powder or crystals

Definition

ChEBI: A N-methyl-L-alpha-amino acid that is the Nalpha-methyl derivative of L-tryptophan.

Biochem/physiol Actions

An indoleamino acid that shows radical scavenging and antioxidant properties in vitro.

Purification Methods

Crystallise L-abrine from H2O or EtOH/H2O mixture and dry it for 2days at 60o in high vacuum; it has m 275-290o(dec with browning at 230o) and [] D +47.2o (c 2, 0.5N HCl) [Peter et al. Helv Chim Acta 46 577 1963]. [Gregory & Morley J Chem Soc 913 1968, Beilstein 22/14 V 40.]
