    Synthesis of some amino and carboxy analogs of galabiose; evaluation as inhibitors of the pilus protein PapGJ96 from Escherichia coli
    摘要:
    The 2'-amino-2'-deoxy, 6-amino-6-deoxy, and 6-carboxy analogs of the reference inhibitor 2-(trimethylsilyl)ethyl (alpha-D-galactopyranosyl)-(1-->4)-beta-D-galactopyranoside were synthesized and evaluated as inhibitors of the binding of the Escherichia coli-derived pilus protein PapG(J96), using an ELISA assay. The inhibitory efficiencies (K-rel; relative to the reference inhibitor) were: 157, 13, and < 8, respectively. The results support the previously proposed combining site model, where the protein carries a negatively charged amino acid residue near HO-2' and HO-6 of the galabioside.

    基于端基反应性的一锅寡糖合成:通往寡糖文库的快速途径。
    摘要:
    寡糖文库的组装已采用“一锅法”以实用和有效的方式实现。借助巯基糖苷的异头反应性值,使用具有一个游离羟基的巯基糖苷(单糖或二糖)作为受体和供体,再结合另一种完全保护的巯基糖苷,可以选择性地形成二糖或三糖,而不会自缩合,随后原位与无异性的糖苷(单糖或二糖)反应,以高总收率形成三糖或四糖。该方法可以使用设计的构建基块快速组装33种直链或支链完全保护的寡糖。

  • <i>O</i>-Glycosylation Enabled by <i>N-</i>(Glycosyloxy)acetamides
    作者:Miao Liu、Bo-Han Li、De-Cai Xiong、Xin-Shan Ye

    日期:2018.8.3
    A novel glycosylation protocol has been established by using N-(glycosyloxy)acetamides as glycosyl donors. The N-oxyacetamide leaving group in donors could be rapidly activated in the presence of Cu(OTf)2 or SnCl4 under microwave irradiation. This glycosylation process afforded the coupled products in high yields, and the reaction enjoyed a broad substrate scope, even for disarmed donors and hindered
    通过使用N-(糖基基)乙酰胺作为糖基供体已经建立了新的糖基化方案。在微波辐射下,存在Cu(OTf)2或SnCl 4的情况下,供体中的N-酰胺离去基团可以快速活化。该糖基化过程以高收率提供了偶联产物,并且该反应享有广泛的底物范围,即使对于缴械的供体和受阻的受体也是如此。供体的容易获得,N-(糖基基)乙酰胺的高稳定性以及小的离去基团使该方法非常实用。

    configuration. This study investigated the use of 2-azido-2-deoxythioglycosides for 1,2-trans-β-glycosidic bond formation under low-concentration glycosylation conditions. Further application of the 2-azido-2-deoxythioglycosyl substrates for one-pot oligosaccharide synthesis was demonstrated in the synthesis of protected β-(16)-N-acetylglucosamine trimer, core-6–serine conjugate, and F1–α serine conjugate.

    strategy for a wide range of glycosyl donors and acceptors has been developed, which is based on an in situ adduct transformation protocol. Based on this strategy, both NFM-derived and iodide covalent adducts can be accessed for glycosylation. Using low temperature NMR spectroscopy, the aforementioned glycosyl adducts were detected.

    A regioselective benzylation or p-methoxybenzylation of diols in azido-containing monosaccharide derivatives was reported, and the reaction was performed under the conventional reaction conditions (NaH/BnBr in DMF). The hydroxyl functionality adjacent to the azido group was benzylated selectively in good yields.

    α2-6sialyltransferase-catalyzed reactions. These structures, together with β-linked cores 1–4 and 6, and their sialylated forms, were fabricated into a comprehensive O-GalNAc core microarray to profile the binding of clinically important GalNAc-specific lectins. It is found that only Tn, (sialyl-)core 5, and core 7 are the binders of WFL, VVL, and SBA, while DBA only recognized (sialyl-)core 5, and Jacalin is the
    所有O -GalNAc 聚糖均源自 8 个核心,其中 2 或 3 个单糖通过α- 或 β- 糖苷键连接。虽然 β 连接核心 1-4 和 6 以及衍生聚糖的化学化学酶合成方法已得到很好的发展,但由于存在这种 1,2-cis,α 连接稀有核心 5、7 和 8 的制备具有挑战性连锁。与此同时,人们对这些结构的生物合成和功能作用知之甚少。在这里,我们通过多方面的化学调制从多功能前体合成了 3 个具有独特 α 配置的 α 连接稀有核心。然后通过少女发光杆菌α2-6 唾液酸转移酶催化反应实现了稀有核心的有效区域选择性 α2-6 唾液酸离子。这些结构与 β 连接核心 1-4 和 6 及其唾液酸化形式一起,被制作成全面的O -GalNAc 核心微阵列,以分析临床上重要的 GalNAc 特异性凝集素的结合。发现只有Tn、(唾液酸-)核心5和核心7是WFL、VVL和SBA的结合物,而DBA仅识别(唾液酸-)
