DJENKOLIC ACID Usage And Synthesis

Uses

Djenkolic Acid can be used as a pharmaceutical composition consisting of cannabinoid.

Definition

ChEBI: A dithioacetal consisting of two molecules of L-cysteine joined via their sulfanyl groups to methylene.

Purification Methods

Crystallise djenkolic acid from a large volume of water (solubility is 0.5g%). [du Vigneaud & Patterson J Biol Chem 114 533 1936, Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 pp 2682, 2687 1961, Beilstein 4 III 1591.] The N,N’-dibenzoyl derivative crystallises with 1H2O from aqueous EtOH with m 87.5-89o [Beilstein 9 III 1171.]
