A series of novel fatty acid derivatives of pyridoxine, one of the three members of the vitamin B 6 group, has been prepared. These products were obtained using an enzymatic approach. Several lipases catalyzed esterification and transesterification reactions of pyridoxine with carboxylic acid or alkyl carboxylates showed a remarkable regioselective behavior; only monoacyl derivatives were obtained. The surfactant activity, composition and clean enzymatic methodology applied in the preparation of these products make them useful as ingredients in cosmetic and pharmaceutical formulations or food additives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
