  • Synthesis of Sialic Acids, Their Derivatives, and Analogs by Using a Whole-Cell Catalyst

    Sialic acids (Sias) are important constituents of cell surface glycans. Ready access to Sias in large quantities would facilitate the development of carbohydrate‐based vaccines and small‐molecule drugs. We now present a facile method for synthesizing various natural forms and non‐natural derivatives or analogs of Sias by using a whole‐cell catalyst, which is constructed by adding a plasmid containing
    唾液酸(Sias)是细胞表面聚糖的重要成分。大量使用Sias可以方便地开发基于碳水化合物的疫苗和小分子药物。现在,我们提出了一种通过使用全细胞催化剂来合成Sias的各种天然形式和非天然衍生物或类似物的简便方法,该方法是通过将包含必需酶基因的质粒添加到大肠杆菌的代谢工程菌株中来构建的。掺入的酶(N-乙酰氨基葡萄糖2-表异构酶N-乙酰神经氨酸醛缩酶)使细胞催化剂可以通过易于扩展的发酵过程将各种简单廉价的糖类转化为各种与Sia相关的化合物。此外,使用这种全细胞生物转化结合三个常规酶促反应的合成提供了一系列复杂的含Sia的聚糖(唾液寡糖)及其带有不同取代基的衍生物。本文所述的方法应允许大规模且经济地生产Sias和唾液酸低聚糖,并且可以补充现有的化学和酶促策略。

  • A gas-to-solid phase methanolysis method for the analysis of small amounts of oligosaccharides
    作者:Daniel Derbie Asres、Hélène Perreault
    DOI:10.1139/v96-168
    日期:1996.8.1

    A gas-to-solid phase methanolysis method for the analysis of oligosaccharides is presented. The advantages of using this new gas-to-solid phase method, as opposed to conventional bulk phase techniques, are described, along with comparisons of results obtained from both techniques. The reliable bulk phase methanolysis methods are used as benchmarks for assessing the extent of completion of the gas-to-solid reactions. Gas chromatographic – mass spectrometric (GC–MS) data show that, in general, higher temperatures and longer reaction times are required for completion of the gas-to-solid methanolysis process than for completion of the bulk phase reaction. On the other hand, the gas-to-solid procedure requires only minimal amounts of substrate that would be difficult to characterize using bulk phase methanolysis due to losses during clean-up procedures. Gas-to-solid methanolysis reactions of permethylated di- and trisaccharides were investigated (GC–FID and GC–MS), following initial experiments performed in order to characterize the GC retention times and mass spectra of permethylated standard monosaccharides. Conversion of neutral disaccharides, as well as neutral and acidic trisaccharides, to their respective monosaccharides was successful using the gas-to-solid method. The GC–FID and GC–MS traces show that the gas-to-solid method gives a cleaner reaction than the bulk phase method. Key words: oligosaccharides, methanolysis, permethylation, gas chromatography – mass spectrometry, mass spectrometry.

    本文介绍了一种气-固相甲醇解法用于分析低聚糖。与传统的大量相技术相比,使用这种新的气-固相方法的优点被描述,并对两种技术得到的结果进行了比较。可靠的大量相甲醇解法被用作评估气-固反应完成程度的基准。气相色谱-质谱(GC-MS)数据表明,通常需要更高的温度和更长的反应时间才能完成气-固相甲醇解过程,而不是完成大量相反应。另一方面,气-固过程仅需要少量的底物,这些底物在清洁过程中很难用大量相甲醇解法表征。对甲基化的二糖和三糖进行了气-固相甲醇解反应的研究(GC-FID和GC-MS),并进行了初步实验以表征甲基化标准单糖的GC保留时间和质谱图。使用气-固法成功地将中性二糖以及中性和酸性三糖转化为它们各自的单糖。GC-FID和GC-MS图表明,与大量相法相比,气-固法给出了更干净的反应。关键词:低聚糖,甲醇解,甲基化,气相色谱-质谱,质谱。
