Chemo-enzymatic synthesis of N-arachidonoyl glycine.
N-Arachidonoyl glycine was synthesized in a chemo-enzymatic process where glycine tert -butyl ester was acylated by arachidonic acid and the resulted ester was then de-protected to give the final product. Among various lipases tested and chosen for their ability to cleave fatty amides, that from Candida antarctica B gave the best results resulting in a 39% hydrolysis after 24 h. This enzyme was then used for the reverse N-acylation synthesis and gave a 75% product formation after 24 h using methyl ester of arachadonic acid as acyl donor and acetonitrile as solvent. Direct acylation of glycine gave less than 10% yield.
