Ceramides are spingolipid compounds that are very attractive as active components in both the pharmaceutical and the cosmetic industries. In this study, the synthesis of ceramide analogs, the so-called pseudo-ceramides, was carried out using for the first time a two-step continuous enzymatic process with immobilized Candida antarctica lipase B (Novozym ® 435) in a packed-bed bioreactor. The first step involved the selective N-acylation of 3-amino-1,2-propanediol using stearic acid as the first acyl donor (i). This was followed by the selective O-acylation of the N-stearyl 3-amino-1,2-propanediol synthesized in the first step, with myristic acid as the second acyl donor, to produce a N,O-diacyl 3-amino-1,2propanediol-type pseudo-ceramide, namely 1-O-myristyl,3-N-stearyl 3-amino-1,2propanediol (ii). The process was first optimized by evaluating the influences of three factors: feed flow rate, quantity of biocatalyst and substrate concentration. Under optimal conditions an amide synthesis yield of 92% and a satisfying production rate of almost 3.15 mmol h-1
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations 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.
