  • Synthesis of Benzaldehyde-Functionalized Glycans: A Novel Approach Towards Glyco-SAMs as a Tool for Surface Plasmon Resonance Studies
    作者:Sebastian Kopitzki、Knud J. Jensen、Joachim Thiem
    DOI:10.1002/chem.200902693

    In recent years the interest in tools for investigating carbohydrate–protein (CPI) and carbohydrate‐carbohydrate interactions (CCI) has increased significantly. For the investigation of CPI and CCI, several techniques employing different linking methods are available. Surface plasmon resonance (SPR) imaging is a most appropriate tool for analyzing the formation of self‐assembled monolayers (SAM) of
    近年来,人们对研究碳水化合物-蛋白质(CPI)和碳水化合物-碳水化合物相互作用(CCI)的工具的兴趣大大增加。为了调查CPI和CCI,可以使用几种采用不同链接方法的技术。表面等离振子共振(SPR)成像是分析碳水化合物生物可模仿糖萼的自组装单分子膜(SAM)形成的最合适工具。与先前用于分析CPI和CCI的SPR成像方法相反,本文报道的新颖方法可轻松,快速地合成接头间隔子和碳水化合物生物,并通过控制配体的数量和方向来增强结合作用。为了通过还原胺化固定在具有生物排斥性的基官能化SPR芯片上,已通过包括烃复分解在内的几个简便步骤合成了多种醛官能化的聚糖结构(葡萄糖,半乳糖甘露糖葡糖胺纤维二糖乳糖乳糖胺)。提出了针对凝集素伴刀豆球蛋白A的有效固定方法和首次结合研究。
  • Fluorescently Labeled Substrates for Monitoring α1,3‐Fucosyltransferase IX Activity

    metastasis. Fucosyltransferases catalyze the transfer of fucose residues from the activated donor molecule GDP‐β‐L‐fucose to various acceptor molecules. However, detailed information about the reaction processes is still lacking for most fucosyltransferases. In this work we have monitored α1,3fucosyltransferase activity. For both donor and acceptor substrates, the introduction of a fluorescent ATTO dye
    岩藻糖基化通常是聚糖生物合成的最后一个过程。由此产生的聚糖参与多种生物过程,如细胞粘附、炎症或肿瘤转移。岩藻糖基转移酶催化从活化的供体分子 GDP-β- L转移岩藻糖残基-岩藻糖到各种受体分子。然而,大多数岩藻糖基转移酶仍然缺乏有关反应过程的详细信息。在这项工作中,我们监测了 α1,3-岩藻糖基转移酶的活性。对于供体和受体底物,荧光 ATTO 染料的引入是合成的最后一步。随后通过 α1,3-岩藻糖基转移酶将这些底物转化为荧光标记的产物,通过高效薄层色谱结合质谱以及双色荧光互相关光谱进行检查,结果表明两种荧光标记的供体 GDP -β - L-岩藻糖-ATTO 550 和受体N-乙乳糖胺-ATTO 647N 被重组人岩藻糖基转移酶 IX 接受,分别为幽门螺杆菌α1,3-岩藻糖基转移酶。荧光互相关光谱分析允许对酶促反应的进程进行快速和通用的估计,因此该方法可用作研究岩藻糖基转移酶反应的替代方法。
  • Sulfonium Salts of Iodine(I) Species as Efficient Reagents for the Regioselective Bisfunctionalisation of ­Glycals and Enol Ethers
    作者:Thurpu Raghavender Reddy、Dodla Sivanageswara Rao、Kalvacherla Babachary、Sudhir Kashyap

    A new sulfonium-salt-based iodine(I) reagent system for the vicinal functionalisation of glycals and enol ethers has been developed. The unprecedented iodine(I) complex, Me3SI(OAc)2, generated in situ from Me3SI and PhI(OAc)2, effectively promoted the one-pot iodocarboxylation using carboxylic acids, and iodoazidation using NaN3 or TMSN3 (trimethylsilyl azide). The scope and generality of the new reagent

  • Synthesis of multivalent N-acetyl lactosamine modified quantum dots for the study of carbohydrate and galectin-3 interactions
    作者:Yang Yang、Xiao-Chao Xue、Xiao-Feng Jin、Li-Jun Wang、Yin-Lin Sha、Zhong-Jun Li
    DOI:10.1016/j.tet.2012.06.035
    日期:2012.9
    Ternary core/shell CdSeS/ZnS-QDs coated with N-acetyl lactosamine was prepared as a fluorescent probe to study the interactions of N-acetyl lactosamine and galectin-3. The synthesis of N-acetyl lactosamine was achieved through the 'azidoiodoglycosylation' method. The amount of ligand coated on QDs was determined by H-1 NMR and ICP-OES. The interactions between carbohydrates and galectin-3 were measured using SPR. The results revealed that the affinity of galectin-3 with di- and multivalent N-acetyl lactosamine increased 20 and 184-fold, respectively. The prepared glyco-QDs could be used as an efficient fluorescent probe to study carbohydrates and galectin-3 interactions. (C) 2012 Elsevier Ltd. All rights reserved.
  • A convenient access to β-glycosides of N-acetyllactosamine
    作者:Dominique Lafont、Paul Boullanger、Francine Carvalho、Philippe Vottero

    日期:1997.1
    Iodoacetoxylation of 3,6-di-0-acetyI-4-0-(2,3,4,6-tetra-O-acetyl-beta-D-galactopyranosyl)-1,5-anhydro-2-deoxy-D-arabino-hex-1-enitol (hexa-O-acetyllactal) and the corresponding hexa-O-benzoyl derivative, gave the alpha-1,2-trans 1-O-acetyl-2-deoxy-2-iodo adducts with high stereoselectivity and good yields. These were treated with an excess of trimethylsilyl azide in the presence of trimethylsilyl trifluoromethanesulfonate affording the corresponding alpha-1,2-trans 2-deoxy-2-iodoglycosyl azides. In the presence of an alcohol, a Staudinger reaction at the anomeric azide ledin situ to an iminophosphorane which rearranged with elimination of iodine at C-2. The aziridine intermediate thus obtained reacted with a suitable alcohol to afford the corresponding lactosamine beta-glycosides. The reaction occurred with double inversion of configuration at C-1 and C-2. Deprotection of the amine functionality and further transformation into the acetamido derivatives could be achieved without isolation of the intermediates. (C) 1997 Elsevier Science Ltd.
