Optical Activity UNSPECIFIED

Naproxen methyl ester, a mixture of two isomers R and S, is the precursor of therapeutically important nonsteroidal anti-inflammatory drug naproxen. Naproxen methyl ester can be enantioselectively hydrolyzed by lipases or (S)-enantioselective esterase could catalyze the selective hydrolysis of the (S)-Naproxen methyl ester, giving optically pure (S)-naproxen. In addition, S-naproxen methyl ester is used as a tool for identification and determination of new stereo selective carboxylesterase activities.
