  Studies of cyclodextrin effect for glycosylation by galactosyltransferase

  摘要：

  Cyclodextrins (CDs) do not disturb HPLC purification and do not form lather, which makes them superior to commonly used surfactants. In this paper, the authors describe the utility of CDs, specifically alpha-CD, beta-CD, and gamma-CD, for the synthesis of neoglycolipids from insoluble peptide-linked substrates. gamma-CD was found to be well matched to the bulky benzyl group and accelerated the reaction for the substrate having Phe (F), while beta-CD was well matched to the methyl group and accelerated the reaction for the substrate having Ala (A). Galactosylation to water-insoluble peptide-linked glucosaminide substrate by galactosyltransferase proceeded 63% at the most, but using either beta-CD or gamma-CD gave quantitative yield within 10 h.

  Chemical and enzymatic synthesis of neoglycolipids in the presence of cyclodextrins

  摘要：

  The efficiency of cyclodextrins (CDs), alpha-CD, beta-CD and gamma-CD, for the blotting of hydrophobic substrates to water-soluble polymers and for the synthesis of neoglycolipids using glycosyltransferase is described. CDs did not disturb HPLC purification and did not bring lather. These merits are superior to surfactants commonly used in such a case. The utility of CDs as a novel and efficient supporting material for enzymatic glycosylation is also discussed. (C) 2008 Elsevier Ltd. All rights reserved.
