Article: Structures of cell-wall phosphate-containing glycopolymers of Bifidobacterium longum BIM B-476-D.
[show abstract] [hide abstract]
ABSTRACT: Glycopolymers with oligosaccharyl phosphate repeats of two types and ribitol and glycerol teichoic acids were isolated from cell wall of Bifidobacterium longum BIM B-476-D by stepwise extraction with 10% CCl3CO2H. The following structures of the glycopolymers were established by sugar analysis, selective cleavage with aq 2% HOAc, dephosphorylation with 48% HF, 2D NMR spectroscopy, and high-resolution ESI MS: The ribitol teichoic acid also contains minor d-alanine, whose position was not determined.Carbohydrate research 03/2013; 373C:22-27. · 2.03 Impact Factor -
Article: Synthesis of branched arabinofuranose pentasaccharide fragment of mycobacterial arabinans as 2-azidoethyl glycoside.
[show abstract] [hide abstract]
ABSTRACT: Branched arabinofuranose pentasaccharide with 2-azidoethyl aglycon was prepared for the first time by [3+1+1] bis-(1,2-cis)-glycosylation of trisaccharide diol with silyl-protected thioglycoside glycosyl donor. The presence of 2-azidoethyl aglycon would enable the preparation of neoglycoconjugates using the click chemistry approaches.Carbohydrate research 05/2012; 357:62-7. · 2.03 Impact Factor
