    N-聚糖合成的双重区域和立体选择性糖基化策略。
    摘要:
    已经开发了一种用于糖蛋白(N-聚糖)的双天线N-连接寡糖的构建方法。从包含亚苄基保护的β-甘露糖苷的核心三糖(β-甘露糖基壳二糖)开始,用于触角的二糖结构单元的连接可以以区域和立体选择性的双重方式进行。开发了GlcNPhtbeta1,2Man供体的简短合成。作为对β-甘露糖苷的最小保护,亚苄基乙缩醛部分允许2,3-二醇在OH-3处与GlcNbeta1,2Man三氯乙酰亚氨酸酯供体进行选择性α-糖基化。随后的脱苄基作用产生4,6-二醇,其可以在OH-6处选择性地延伸。当使用邻苯二甲酰亚胺保护的供体时,OH-4的过度反应通常较低。

  • Chemoenzymatic Synthesis of N-glycan Positional Isomers and Evidence for Branch Selective Binding by Monoclonal Antibodies and Human C-type Lectin Receptors

    Here, we describe a strategy for the rapid preparation of pure positional isomers of complex N-glycans to complement an existing array comprising a larger number of N-glycans and smaller glycan structures. The expanded array was then employed to study context-dependent binding of structural glycan fragments by monoclonal antibodies and C-type lectins. A partial enzymatic elongation of semiprotected
    在这里,我们描述了一种快速制备复杂N-聚糖的纯位置异构体的策略,以补充包含大量N-聚糖和较小聚糖结构的现有阵列。然后将扩展的阵列用于研究单克隆抗体和C型凝集素对结构聚糖片段的背景依赖性结合。通过制备型HPLC将半保护核心结构的部分酶促延伸与位置异构体的保护基辅助分离相结合。该方法避免了繁琐的触角化学区分,被用于制备八种带有Galβ1,4GlcNAc(LN),GalNAcβ1,4GlcNAc(LDN)和GalNAcβ1,4[Fucα1,3] GlcNAc(LDNF)的双触角N-聚糖。 )出现在一个或两个触角上的图案。三种抗Le抗体结合特异性的筛选针对曼氏沙门氏菌聚糖和先天免疫系统的三个C型凝集素受体(即DC-SIGN,DC-SIGNR和LSECtin)产生的X单克隆IgM抗体显示出令人惊讶的上下文相关的精细特异性,可识别聚糖基序。此外,我们观察到,通过测试的C型凝集素,一个单独的位置异构体比

    A convergent synthesis of the biantennary and core-fucosylated octasaccharide 20 (a protected form of A) is described. Octasaccharide 20 is designed to serve as a precursor for dodecasaccharide 1, a complex N-glycan frequently found in glycoproteins of the serum and the cell surface.

  • Synthesis of a truncated bi-antennary complex-type N-glycan oxazoline; glycosylation catalysed by the endohexosaminidases Endo A and Endo M
    作者:Thomas B. Parsons、James W. B. Moir、Antony J. Fairbanks
    DOI:10.1039/b907273j
    日期:——
    The synthesis of a truncated complex N-glycan hexasaccharide oxazoline was achieved producing a substrate that was assayed as an activated donor for glycosylation catalysed by the endohexosaminidases Endo A and Endo M. For Endo M competitive product hydrolysis was seen to limit synthetic efficiency. In spite of its natural hydrolytic selectivity wild type Endo A was able to process the truncated complex N-glycan oxazoline, albeit with limited synthetic efficiency; notably the product was not a substrate for Endo A catalysed hydrolysis. Two Endo A mutants, E173Q and E173H, were also assayed, but were unable to process this oxazoline.
    我们成功合成了一种截断的复杂N-糖苷六糖苷酸的噁唑啉,并将其作为底物进行评估,以用作由内糖胺酶Endo A和Endo M催化的糖基化反应的活化供体。对于Endo M,竞争性产物解被观察到限制了合成效率。尽管天然的解选择性较高,野生型Endo A仍能够处理这种截断的复杂N-糖苷噁唑啉,但合成效率有限;值得注意的是,所生成的产物并不是Endo A催化解的底物。同时评估了两个Endo A突变体,E173Q和E173H,但它们无法处理该噁唑啉。
  • Modular Synthesis of Core Fucosylated N-Glycans
    作者:Dimitri Ott、Joachim Seifert、Ingo Prahl、Mathäus Niemietz、Joanna Hoffman、Janna Guder、Manuel Mönnich、Carlo Unverzagt

    日期:2012.9
    A modular synthesis of complex-type N-glycans containing the core fucosyl motif was optimized. The core trisaccharide building block was protected by a methoxyphenyl group for convenient core fucosylation. The trisaccharide was obtained on a large scale from the glycosylation of the corresponding chitobiosyl azide with a glucosyl donor followed by intramolecular inversion. Improved methods were established
    优化了包含核心岩藻糖基基序的复杂型 N-聚糖的模块化合成。核心三糖结构单元由甲氧基苯基保护,以方便核心岩藻糖基化。三糖是通过相应的壳二糖叠氮化物葡萄糖基供体的糖基化,然后进行分子内转化而大规模获得的。建立了用于合成单糖结构单元及其偶联的改进方法。β-甘露糖苷的转化伴随着先前未注意到的副反应,导致亚碳酸酯中间体的解开环。通过两个区域选择性和立体选择性偶联,亚苄基保护的核心三糖被延长成双触角 N-聚糖七糖。最后的岩藻糖基化也产生了一些β端基异构体,

    developed for the synthesis of multiantennary N‐glycans of the complex type, which are commonly found on glycoproteins. The donor building blocks were laid out for the elongation of a core trisaccharide acceptor (β‐mannosyl chitobiose) conveniently protected with a single benzylidene moiety at the β‐mannoside. Through two consecutive regio‐ and stereoselective couplings the donors gave N‐glycans with three
    开发了一组模块化的寡糖构建基块,用于合成复杂类型的多天线N聚糖,这些糖通常在糖蛋白上发现。布置了供体结构单元,以延长核心三糖受体(β-甘露糖壳二糖)的延伸,该受体方便地由β-甘露糖苷上的单个亚苄基部分保护。通过两个连续的区域和立体选择性偶联,供体以高产量获得了具有三到五个触角的N-聚糖。由于供体的保护基图案一致,可以通过使用一般的反应顺序对最终产物进行脱保护。
