  • Synthetic avenues towards a tetrasaccharide related to <i>Streptococcus pneumonia</i> of serotype 6A
    作者:Aritra Chaudhury、Mana Mohan Mukherjee、Rina Ghosh
    DOI:10.3762/bjoc.14.95
    日期:——

    Streptococcus pneumonia (SPn) is a Gram-positive bacterium which causes life threatening diseases. The bacteria protect themselves against non-specific host defence by an external polysaccharide (PS) capsule which bears a repeating unit, α-D-Galp(1->3)-α-D-Glcp(1->3)-α-L-Rhap(1->3)-D-Rib (SPn 6A). A closer look at the structure reveals the presence of α-linked galactose and glucose residues. The synthesis of these 1,2-cis glycosidic linkages are considered challenging particularly in the context of a one-pot oligosaccharide synthesis. We have synthesized the aforesaid tetrasaccharide (SPn 6A) based on both stepwise and sequential one-pot glycosylation reactions using easily accessible common building blocks; eventually similar overall yields were obtained in both cases.

    肺炎链球菌(SPn)是一种革兰氏阳性细菌,能引起威胁生命的疾病。这些细菌通过一种外部多糖(PS)胶囊来保护自己,免受宿主非特异性防御,这种胶囊带有重复单元,α-D-Galp(1->3)-α-D-Glcp(1->3)-α-L-Rhap(1->3)-D-Rib(SPn 6A)。仔细观察其结构可以发现α连接的半乳糖和葡萄糖残基的存在。这些1,2-cis糖苷键的合成被认为是具有挑战性的,特别是在一锅寡糖合成的情况下。我们已经合成了上述的四糖(SPn 6A),基于逐步和顺序的一锅糖基化反应,使用易于获取的常见构建模块;最终在这两种情况下获得了相似的总收率。
  • Design, synthesis, and immunochemical characterization of a chimeric glycopeptide corresponding to the Shigella flexneri Y O-polysaccharide and its peptide mimic MDWNMHAA

    pentasaccharide corresponding to the S. flexneri Y O-polysaccharide and the octapeptide mimic, MDWNMHAA. Both chimeric molecules consist of a rhamnose trisaccharide linked through an alpha- or beta-thioglycosidic linkage to a MDW moiety in which the W unit has been modified. We predicted that omission of the NMHAA moiety would obviate the bound water molecules that provided complementarity with the antibody-combining
    设计了两种对应于弗氏志贺氏菌Y O-多糖的糖肽嵌合体及其肽模拟物,以试图通过相对于O-多糖的原始八肽模拟物增加结合熵来改善结合亲和力。该设计基于单克隆抗体SYA / J6的X射线晶体结构及其相关配体,对应于弗氏链球菌Y O多糖的五糖和八肽模拟物MDWNMHAA的复合物。两个嵌合分子均由鼠李糖三糖组成,鼠李糖三糖通过α-或β-硫糖苷键连接至其中W单元已被修饰的MDW部分。我们预测,省略NMHAA部分将消除与抗体结合位点互补的结合水分子,以及由于在肽的C-末端施加α-转角而导致的构象限制。然后使用程序自动停靠3.0将糖肽对接至SYA / J6的活性位点,并对其结构进行优化。在每种情况下获得的最佳模型表明,具有α-或β-硫糖苷键的嵌合分子可能是抗体的合理替代配体。我们在这里报告使用溶液和固相策略合成α-糖肽。免疫化学表征表明,不幸的是,α-糖肽没有抑制SYA / J6与弗氏链球菌Y脂多糖的结合。
