  Effect of acyl chain length on selective biocatalytic deacylation on O-aryl glycosides and separation of anomers

  摘要：

  It has been demonstrated that Lipozyme (R) TL IM (Thermomyces lanuginosus lipase immobilised on silica) can selectively deacylate the ester function involving the C-5' hydroxyl group of alpha-anomers over the other acyl functions of anomeric mixture of peracylated O-aryl alpha,beta-D-ribofuranoside. The analysis of results of biocatalytic deacylation reaction revealed that the reaction time decreases with the increase in the acyl chain length from C-1 to C-4. The unique selectivity of Lipozyme (R) TL IM has been harnessed for the separation of anomeric mixture of peracylated O-aryl alpha,beta-D-ribofuranosides, The lipase mediated selective deacylation methodology has been used for the synthesis of O-aryl alpha-D-ribofuranosides and O-aryl beta-D-ribofuranosides in pure forms, which can be used as chromogenic substrate for the detection of pathogenic microbial parasites containing glycosidases.
