    Total synthesis of fuzinoside
    摘要:
    The first total syntheses of fuzinoside (1b) were achieved from o-galactose through two strategies (BCA and ABC) in 11 (total yield: 5.0%) and 15 (total yield: 3.7%) steps, respectively. Comparison of NMR data of synthetic compound 1b and those of the fuzinoside isolated from the lateral roots of Aconitum carmicaelii suggests that the structure reported in the literature(1,2) might not be accurate. The synthetic fuzinoside (1b) exhibited moderate cardiac activity in the isolated bullfrog heart assay. (C) 2014 Elsevier Ltd. All rights reserved.

    polysaccharide, polysaccharide A1 (PS A1) is found on the capsule of the commensal bacteria Bacteroides fragilis . Its potent immunomodulatory properties have been linked to postoperative intra-abdominal abscess formation. Here, we report the synthesis of the PS A1 tetrasaccharide repeating unit (2) as a tool to investigate the biological role of this polysaccharide. A modular synthetic strategy originating
    几乎所有细菌荚膜多糖都是独立于 T 细胞的抗原,不会促进免疫球蛋白类别从 IgM 转换为 IgG,也不会促进记忆反应。相比之下,两性离子多糖通过主要组织相容性复合物 II 类呈递激活 T 细胞依赖性免疫反应,这种机制以前认为是为肽抗原保留的。研究得最好的两性离子多糖多糖 A1 (PS A1) 存在于共生细菌脆弱拟杆菌的荚膜上。其有效的免疫调节特性与术后腹腔内脓肿的形成有关。在这里,我们报告了 PS A1 四糖重复单元 (2) 的合成,作为研究该多糖生物学作用的工具。源自 PS A1 重复单元还原末端的模块化合成策略不成功,并说明了高度武装的糖基化试剂和差的亲核试剂之间的糖基化反应的局限性。因此,依赖于三糖 5 和丙酮酸乳糖 6 的 [3 + 1] 糖基化用于完成 PS A1 重复单元 (2) 的第一次全合成。

    elongate polyprenol-pyrophosphate linked glycosyl acceptor substrates using UDP-galactofuranose as the donor substrate. We here report the first chemical synthesis of GlfT1 and GlfT2 acceptor substrates containing pyrophosphate and polyprenol moieties (compounds 3, 4, 22 and 23). The approach involves chemical synthesis of an oligosaccharide, subsequent phosphorylation at the reducing end and coupling
