    A convenient route for the synthesis of heparin oligosaccharides involving regioselective protection of D-glucosamine and a concise preparation of rare L-ido sugars from diacetone α-D-glucose is described. Stereoselective coupling of a D-glucosamine-derived trichloroacetimidate with a 1,6-anhydro-β-L-idopyranosyl 4-alcohol gave the desired α-linked disaccharide, which was used as repeating unit for
    合成肝素寡糖的简便方法涉及区域选择性保护 D-葡萄糖胺并从中精制稀有的L - ido糖双丙酮α- D-葡萄糖描述。D-葡糖胺衍生的三氯乙亚氨酸酯与1,6-脱水-β - L-偶氮吡喃糖基4-醇的立体选择性偶联产生所需的α-连接的二糖,其用作双链延长和终止的重复单元。使用D从还原端到非还原端逐步组装-葡糖胺衍生的单糖作为起始单元提供了具有不同链长的寡糖骨架。一系列官能团转化提供了具有3、5和7个糖单元的预期肝素寡糖。这些寡糖与嗜酸性粒细胞衍生的神经毒素(EDN),阳离子核糖核酸酶和人类嗜酸性粒细胞产生的介体的相互作用进行了进一步研究。结果表明,在5μgmL -1时,七糖具有足够强的干扰作用,以阻断EDN与Beas-2B细胞的结合。三糖和五糖在50μgmL -1浓度下具有中等抑制性能,但在10μgmL -1处未观察到抑制作用。IC 50三糖,五糖和七糖的值分别为69.4、47.2和0.225μgmL

    resistance of this pathogen. The Shigella O-antigen is a promising vaccine target. To identify the immune epitopes of the glycan, the first total synthesis of Shigella dysenteriae serotype 10 O-antigen tetrasaccharide containing a (S)-4,6-O-pyruvyl ketal was completed. The 1,2-trans-β-glycosylation & C2 epimerization and conformational locking strategies facilitated the construction of two 1,2-cis-β-glycosidic

    Numerous biomolecules possess alpha-D-glucosamine as structural component. However, chemical glycosylations aimed at this backbone are usually not easily attained without generating the unwanted beta-isomer. We report herein a versatile approach in affording full alpha-stereoselectivity built upon a carefully selected set of orthogonal protecting groups on a D-glucosaminyl donor. The excellent stereoselectivity provided by the protecting group combination was found independent of leaving groups and activators. With the trichloroacetimidate as the optimum donor leaving group, core skeletons of glycosylphosphatidyl inositol anchors, heparosan, heparan sulfate, and heparin were efficiently assembled. The orthogonal protecting groups were successfully manipulated to further carry out the total syntheses of heparosan tri- and pentasaccharides and heparin di-, tetra-, hexa-, and octasaccharide analogues. Using the heparin analogues, heparin-binding hemagglutinin, a virulence factor of Mycobacterium tuberculosis, was found to bind at least six sugar units with the interaction notably being entropically driven.
