    Vibrational signatures of metal-chelated monosaccharide epimers: gas-phase infrared spectroscopy of Rb+-tagged glucuronic and iduronic acid
    摘要:
    通过红外光解光谱研究了碱金属Rb+与两种单糖异构体,即葡萄糖醛酸(GlcA)和呋喃糖酸(IdoA)的气相结合。红外光谱显示出明显的差异,尤其是在IdoA + Rb+的案例中,3625 cm−1处的特征带明显缺失。将实验光谱与经过DFT优化的结构计算光谱进行比较,表明Rb+标记的GlcA和IdoA各自采用了独特的复合模式。在GlcA中,主要观察到β-异构体4C1椅式复合物,而对于IdoA,数据则与α-异构体1C4椅式结构以及相应的β-异构体一致。Rb+结合模式的差异解释了红外多光子解离(IR-MPD)光谱中的差异。尽管Rb+与GlcA的结合保持了OH基团之间的分子内氢键网络不变,但该网络在IdoA中受到破坏。因此,IdoA + Rb+缺乏强氢键的现象与3625 cm−1处红移的OH伸缩振动带的缺失有很好的关联。

    Methods for the preparation of oligosaccharide products from polysaccharide starting materials are disclosed. The methods include: hydrolyzing a glucosamine-containing polysaccharide starting material, such as heparin or heparosan, under conditions sufficient to form an oligosaccharide intermediate (e.g., a GlcN-IdoA disaccharide intermediate or a GlcA-GlcN disaccharide intermediate), and converting the oligosaccharide intermediate to the oligosaccharide product. Conversion of the oligosaccharide intermediates to the oligosaccharide products may include one or more esterification, acylation, epimerization, protection, and deprotection steps. Preparation of higher-order oligomers is described, as well as methods for selective oligosaccharide sulfation.

  • Solid- and solution-phase synthesis of heparin and other glycosaminoglycans

    Described is a modular, general synthetic strategy for the preparation in solution and on a solid support of heparin, heparin-like glycosaminoglycans, glycosaminoglycans and non-natural analogs of each of them. Additionally, the modular strategy provides the basis for the preparation of combinatorial libraries and parallel libraries of defined glycosaminoglycan oligosaccharides. The defined glycosaminoglycan structures may be used in high-throughput screening experiments to identify carbohydrate sequences that regulate a host of recognition and signal-transduction processes. The determination of specific sequences involved in receptor binding holds great promise for the development of molecular tools which will allow modulation of processes underlying viral entry, angiogenesis, kidney diseases and diseases of the central nervous system. Notably, the present invention enables the automated synthesis of glycosaminoglycans in much the same fashion that peptides and oligonucleotides are currently assembled.
    本文介绍了一种模块化的、通用的合成策略,用于在溶液和固相支持上制备肝素、类肝素的糖胺聚糖、糖胺聚糖和它们的非天然类似物。此外,这种模块化策略为定义的糖胺聚糖寡糖的组合式库和并行式库的制备提供了基础。这些定义的糖胺聚糖结构可以用于高通量筛选实验,以识别调节多种识别和信号传导过程的碳水化合物序列。确定参与受体结合的特定序列对于开发分子工具来调节病毒进入、血管生成、肾脏疾病和中枢神经系统疾病的过程具有巨大的前景。值得注意的是,本发明使糖胺聚糖的自动化合成方式与目前蛋白质和寡核苷酸的组装方式非常相似。
