    Synthetic and Immunological Studies of Mycobacterial Lipoarabinomannan Oligosaccharides and Their Protein Conjugates
    摘要:
    Lipoarabinomannan (LAM) is one of the major constituents of the Mycobacterium tuberculosis cell wall and an attractive molecular scaffold for antituberculosis drug and vaccine development. In this paper, a convergent strategy was developed for the synthesis of LAM oligosaccharides with an alpha-1,2-linked dimannopyranose cap at the nonreducing end. The strategy was highlighted by efficient coupling of separately prepared nonreducing end and reducing end oligosaccharides. Glycosylations were mainly achieved with thioglycoside donors, which gave excellent yields and stereoselectivity even for reactions between complex oligosaccharides. The strategy was utilized to successfully synthesize tetra-, hepta-, and undecasaccharides of LAM from D-arabinose in 10, 15, and 14 longest linear steps and 7.84, 7.50, and 2.59% overall yields, respectively. The resultant oligosaccharides with a free amino group at their reducing end were effectively conjugated with carrier proteins, including bovine serum albumin and keyhole limpet hemocyanin (KLH), via a bifunctional linker. Preliminary immunological studies on the KLH conjugates revealed that they could elicit robust antibody responses in mice and that the antigen structure had some influence on their immunological property, thus verifying the potential of the oligosaccharides for vaccine development and other immunological studies.

    来自脂阿糖甘露聚糖 (LAM) 的低聚糖与在 C2 处具有非参与基团的糖基供体的简明合成
    摘要:
    导致结核病 (TB) 的分枝杆菌感染是全球十大主要死亡原因之一,而脂阿拉伯甘露聚糖 (LAM) 已被证实在此过程中发挥着重要作用。在这项研究中,开发了一种方便的合成方法,用于从市售底物和试剂开始合成源自 LAM 的寡糖。实现了在没有相邻参与组的情况下通过与供体糖基化的受体立体选择性构建糖苷键的关键步骤。值得注意的是,采用酶水解制备甘露糖结构单元,并采用桦木反应一步法脱去乙酰基和苄基以及还原叠氮基,避免了多次化学过程。最后,

  • Synthesis of Docosasaccharide Arabinan Motif of Mycobacterial Cell Wall
    作者:Akihiro Ishiwata、Yukishige Ito
    DOI:10.1021/ja109932t
    日期:2011.2.23
    Mycobacterial arabinan is a common constituent of both arabinogalactan (AG) and lipoarabinomannan (LAM). In this study, synthesis of β-Araf containing common arabinan docosasaccharide motif (22 Araf monomer units) of mycobacterial cell wall was achieved. Our synthetic strategy toward arabinan involves (1) the stereoselective β-arabinofuranosylation using both 3,5-O-TIPDS-protected and NAP-protected

    DOI:10.1021/ol4036903
    日期:2014.2.7
    An analog of Mycobacterium tuberculosis lipoarabinomannan (LAM) has been synthesized containing the characteristic structures of all of its three major components; that is, a mannosylated phosphatidylinositol moiety, an oligomannan, and an oligoarabinan. A highly convergent strategy was developed that is applicable to the synthesis of other LAM analogs. The synthetic miniature LAM should be useful
