  • Propargyl mediated intramolecular aglycon delivery (IAD): applications to the synthesis of core N-glycan oligosaccharides
    作者:Emanuele Attolino、Thomas W.D.F. Rising、Christoph D. Heidecke、Antony J. Fairbanks
    DOI:10.1016/j.tetasy.2007.06.026
    日期:2007.7
    and subsequent intramolecular glycosylation occurs with complete control of anomeric stereochemistry to form the Manβ(1→4)GlcNAc linkage. A variety of linear and convergent approaches (1+2, 3+1, 3+2) to the core pentasaccharide are investigated as means of probing the generality and limitations of this type of intramolecular aglycon delivery for the formation of β-mannoside linkages in complex oligosaccharides

  • Observations on the Regioselectivity of Glycosylation of Mannose and Glucose: Selective Glycosylation of the Secondary 4-Hydroxyl of 4,6-Diol Acceptors
    作者:Antony Fairbanks、Thomas Rising、Christoph Heidecke
    DOI:10.1055/s-2007-980355
    日期:2007.6
    The regioselectivity of glycosylation of manno and gluco acceptor diols possessing free hydroxyl groups at the 4- and 6-positions is found to be strongly dependent on functionalization of the 3-hydroxyl group. Surprisingly, highly regioselective glycosylation of the more hindered 4-hydroxyl can be readily achieved in the presence of the primary 6-hydroxyl in cases where the 3-hydroxyl of the acceptor is protected as a benzyl ether and when the donor possesses an ester participating group at the 2-position. However, reverse regioselectivity, namely glycosylation of the 6-hydroxyl, is observed when the 3-hydroxyl has been previously glycosylated.
    研究发现,在 4-和 6-位上具有自由羟基的甘露醇葡萄糖受体二醇的糖基化的区域选择性在很大程度上取决于 3-羟基的官能化。令人惊奇的是,当受体的 3-羟基被保护为苄基醚,且供体的 2-位具有酯参与基团时,在初级 6-羟基存在的情况下,阻碍较大的 4-羟基很容易实现高区域选择性糖基化。然而,当 3-羟基先前已被糖基化时,就会出现反向区域选择性,即 6-羟基的糖基化。
  • Endohexosaminidase-Catalysed Glycosylation with Oxazoline Donors: Fine Tuning of Catalytic Efficiency and Reversibility
    作者:Thomas W. D. F. Rising、Christoph D. Heidecke、James W. B. Moir、Zhenlian Ling、Antony J. Fairbanks

    A complete series of oxazoline di-, tri-, tetra-, and hexasaccharides, corresponding to the core sections of N-linked glycoprotein high mannose glycans, together with the corresponding oligosaccharides containing a central glucose unit, were synthesised and tested as glycosyl donors for glycosylation of a GlcNAcAsn glycosyl amino acid catalysed by the endohexosaminidases M (Endo M), A (Endo A) and

  • An Endoglycosidase with Alternative Glycan Specificity Allows Broadened Glycoprotein Remodelling
    作者:Jonathan J. Goodfellow、Kavitha Baruah、Keisuke Yamamoto、Camille Bonomelli、Benjamin Krishna、David J. Harvey、Max Crispin、Christopher N. Scanlan、Benjamin G. Davis
    DOI:10.1021/ja301334b
    日期:2012.5.16
    Protein endoglycosidases are useful for biocatalytic alteration of glycans on protein surfaces, but the currently limited selectivity of endoglycosidases has prevented effective manipulation of certain N-linked glycans widely found in nature. Here we reveal that a bacterial endoglycosidase from Streptococcus pyogenes, EndoS, is complementary to other known endoglycosidases (EndoA, EndoH) used for current protein remodeling. It allows processing of complex-type N-linked glycans +/- core fucosylation but does not process oligomannose- or hybrid-type glycans. This biocatalytic activity now addresses previously refractory antibody glycoforms.
