摘要
A facile enzymatic synthesis process has been developed to directly prepare the 4-morpholinoethyl ester prodrug of (s)-Naproxen from racemic Naproxen using lipases as the biocatalysts in the organic solvent. With the careful selection of lipase (Lipase MY) and reaction medium (cyclohenane), a high enantiomeric ratio of 136 for the enzyme was obtained. A Ping-Pong Bi Bi mechanism with competitive inhibition by the alcohol was illustrated from the variation of initial rates with substrate concentrations. (C) 1997 by Elsevier Science Inc.
