    摘要:
    Comparison of the in vivo and in vitro effects of S-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl)thiuronium bromide (1), 2-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosylthio-1,3,4-thiadiazolin-5-thione (2), and 2-(2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosylthio)-1,3-benzoxazole (3), as well as the antidiabetics Daonil and insulin on glycosidase enzymes has been investigated. Compound 1 inhibited both alpha- and beta-glucosidases, but the inhibition was more potent with the beta-enzyme. Compound 2 was found to be a weaker inhibitor of these enzymes, while compound 3 showed a slight apparent activation. (C) 2003 Elsevier Ltd. All rights reserved.

Application of this method to a number of model proteins allowed complete and precise site‐selective glycosylation generating glycoconjugates that include, for example, virus‐like particles displaying up to 180 glycans at preselected positions (see scheme).

    A simple procedure for conversion of S-glycosyl isothiourea derivatives into thioglycosides by promotion with triethylamine is described. The reaction conditions allow the synthesis of glycosyl thioesters and some thioglycosides, which cannot be prepared using the traditional approach. The procedure has been successfully applied for preparation of thiooligosaccharides, shown by syntheses of methyl 4-thio-α-cellobioside and methyl 4-thio-α-lactoside derivatives.

  • Preparation and Reactions of 2-Chloroethyl 1-Thio-β-D-glycopyranosides Derived from D-Galactose, D-Glucose, and 2-Acetamido-2-deoxy-D-glucose

    Chloroethyl 1-thio-β-D-glycopyranosides of the D-galacto and D-gluco configurations 5a-5c were prepared by alkylation of the corresponding 1-thio-β-D-hexopyranoses 3a-3c with 1-bromo-2-chloroethane followed by deacetylation. The starting 1-thio-β-D-hexopyranoses were obtained from the acetylated glycopyranosyl halides via isothiouronium salts. It was demonstrated that the chloroethyl thioglycosides 5a-5c undergo hydrolysis in aqueous solutions to give the 2-hydroxyethyl thioglycosides 6a-6c and reducing hexoses and that this hydrolysis proceeds via episulfonium salts. The hydrolysis was monitored by 1H and 13C NMR spectroscopy. In 1% aqueous solutions of sodium carbonate containing phenol or aniline, the thioglycosides 5a-5c provide, in addition to the above hydrolysis products, also the phenoxyethyl and phenylaminoethyl thioglycosides 9a, 10a and 9b, 10b, respectively.
