Lipase‐catalyzed synthesis of polymeric prodrugs of nonsteroidal anti‐inflammatory drugs
Abstract Because of the potential application of prodrugs of nonsteroidal anti‐inflammatory drugs (NSAIDs), Candida antarctica lipase B (CAL‐B) catalyzed polycondensation of profen‐containing diol monomers and diesters were designed to prepare a series of biodegradable polymeric prodrugs composed of...

Abstract Because of the potential application of prodrugs of nonsteroidal anti‐inflammatory drugs (NSAIDs), Candida antarctica lipase B (CAL‐B) catalyzed polycondensation of profen‐containing diol monomers and diesters were designed to prepare a series of biodegradable polymeric prodrugs composed of NSAID branches and poly(amide‐ co ‐ester) backbone. The structure of the products was confirmed by Fourier transform infrared spectroscopy, NMR, and gel permeation chromatography (GPC).
