Abstract
A facile enzymatic synthesis process has been developed to directly pr epare the 4-morpholinoethyl ester prodrug of (s)-Naproxen from racemic Naproxen using lipases as the biocatalysts in the organic solvent. Wi th the careful selection of lipase (Lipase MY) and reaction medium (cy clohenane), a high enantiomeric ratio of 136 for the enzyme was obtain ed. A Ping-Pong Bi Bi mechanism with competitive inhibition by the alc ohol was illustrated from the variation of initial rates with substrat e concentrations. (C) 1997 by Elsevier Science Inc.
