  • Chemoenzymatic Synthesis of a Library of Human Milk Oligosaccharides
    作者:Zhongying Xiao、Yuxi Guo、Yunpeng Liu、Lei Li、Qing Zhang、Liuqing Wen、Xuan Wang、Shukkoor Muhammed Kondengaden、Zhigang Wu、Jun Zhou、Xuefeng Cao、Xu Li、Cheng Ma、Peng George Wang

    decades. In this study, an efficient chemoenzymatic strategy, namely core synthesis/enzymatic extension (CSEE), for rapid production of diverse HMOs was reported. On the basis of 3 versatile building blocks, 3 core structures were chemically synthesized via consistent use of oligosaccharyl thioether and oligosaccharyl bromide as glycosylation donors in a convergent fragment coupling strategy. Each of these
    人乳寡糖(HMO)是人乳中作为主要成分之一存在的各种未结合的聚糖家族。由于HMO的多样性和复杂性,其表征,定量和生物功能研究仍然是一个巨大的挑战。同类HMO库的可访问性对于解决困扰学术界数十年的这些问题至关重要。在这项研究中,报告了一种有效的化学酶策略,即核心合成/酶延伸(CSEE),用于快速生产各种HMO。在3个通用构建基的基础上,通过在收敛片段偶联策略中一致使用寡糖醚和寡糖化物作为糖基化供体,化学合成了3个核心结构。然后,这些核心结构中的每一个都通过4种健壮的糖基转移酶扩展至多达11个HMO化学合成31种HMO的文库,并通过MS和NMR进行表征。CSEE确实提供了一种实用的方法来为各种应用收集结构明确的HMO
  • Synthesis of a hexasaccharide corresponding to a porcine zona pellucida fragment that inhibits porcine sperm-oocyte interaction in vitro

    The synthesis of hexasaccharide1, [Galβ(1-4)GlcNAc[6OSO3]β(1-3)Galβ(1-4)GlcNAcβ(1-3)Galβ(1-3)GalNAcα-O(CH2)3NH2], which corresponds to a porcine zona pellucida fragment that inhibits porcine sperm-oocyte interaction, is described. Compound1 was obtained from fully protected hexasaccharide2, which was in turn constructed from protected Galβ(1-3)GalNAc disaccharide5, containing an α-linked 3-azidopropyl
    六糖1,[Galβ(1-4)GlcNAc [6OSO 3 ]β(1-3)Galβ(1-4)GlcNAcβ(1-3)Galβ(1-3)GalNAcα-O(CH 2)3的合成描述了NH 2 ],其对应于抑制猪精子-卵母细胞相互作用的猪透明带片段。化合物1是从完全保护的六糖2中获得的,而六糖2依次由保护的Galβ(1-3)GalNAc二糖5(包含一个与α连接的3-叠氮丙基间隔基)以及乳糖胺衍生物3和4构成。通过将基糖苷偶联制备二糖3和46具有含有异头代乙基的糖基受体。NIS / TfOH促进了二糖4与5的偶联,得到29,通过选择性除去乙酰丙酰基将其转化为四糖受体30。用3的30进行糖基化,得到保护的六糖2。去除邻二甲酰亚胺基,乙酰化,然后选择性去除丙基和硫酸化,最后完全保护,得到六糖1。
  • Synthesis of Mucin O‐Glycans Associated with Attenuation of Pathogen Virulence
    作者:Giulietta Minzer、Rachel Hevey
    DOI:10.1002/open.202200134
    日期:——
    Recent studies have reported that pooled mucin O-glycans attenuate virulence in diverse pathogens, but the molecular mechanisms have not yet been established. In this work, an optimized synthetic method is described to generate a small library of mucin O-glycans for biological evaluation of discrete structures.

  • Synthesis of the Sda determinant and two analogous tetrasaccharides
    作者:Paul B. van Seeventer、Johannis P. Kamerling、Johannes F.G. Vliegenthart
    DOI:10.1016/s0008-6215(97)00013-x
    日期:1997.4
    To contribute to the possibility of studying in greater detail the biological significance of Sd(a)-containing glycans as occur in Tamm-Horsfall glycoprotein, the following three spacer-linked tetrasaccharides have been synthesized: the Sd(a) determinant alpha-Neup5Ac-(2 --> 3)-[beta D-GalpNAc-(1 --> 4)]-beta-D-Galp-(1 --> 4)-beta-D-GlcpNAc-(1 --> 0)(CH2)(5)NH2 (1), the Gal-analogue alpha-Neup5Ac-(2 --> 3)-[beta-D-Galp-(1 --> 4)]-beta-D-Galp-(1 --> 4)-beta-D-GlcpNAc-(1 --> 0)(CH2)(5)NH2 (2), and the GlcNAc-analogue alpha-Neup5Ac-(2 --> 3)-[beta-D-GlcpNAc-(1 --> 4)]-beta-D-Galp-(1 --> 4)-beta-D-GlcpNAc-(1 --> 0)(CH2)(5)NH2 (3). The general trisaccharide acceptor 5-azidopentyl (methyl 5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-D-glycero-alpha-D-galacto-non-2-ulopyranosylonate)-(2 --> 3)-(2,6-di-O-benzyl-beta-D-galactopyranosyl)-(1 --> 4)-3,6-di-O-benzyl-2-deoxy-2-phthalimido-beta-D-glucopyranoside was prepared, using methyl (phenyl 5-acetamido-4,7,8,9-tetra-O-acetyl-3,5-dideoxy-2-thio-D-glycero-D-galacto-non-2-ulopyranosid)-onate as the sialyl donor. For the syntheses of 1, 2, and 3 the glycosyl donors 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-alpha-D-galactopyranosyl bromide, 2,3,4,6-tetra-O-acetyl-alpha-D-galactopyranosyl bromide, and 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-beta-D-glucopyranosyl trichloroacetimidate, respectively, proved to be the most suitable.
