    基于硫糖基供体的预激活的肿瘤相关碳水化合物抗原Globo-H的多组分一锅法合成
    摘要:
    快速组装肿瘤相关碳水化合物抗原Globo-H六糖2的两种有效途径通过基于预激活的迭代一锅策略进行了报道。第一种方法涉及四个糖基结构单元的顺序偶联,从而在一锅合成中以47%的总收率产生所需的六糖。尽管在Gb3三糖中构建具有挑战性的Gal-α-(1-4)-Gal键的模型研究几乎仅产生了所需的α键,但组装六糖的相似方法导致形成了大量的β异头物。作为替代方案,第二种合成在一个锅中利用了三种成分,并预先形成了Gal-α-(1-4)-Gal键,从而以与四成分方法相似的总收率生产了所需的六糖。两种方法均表明,通过基于预激活的方法,与自动固相合成策略相比,具有更高的糖组装效率,可以在一个罐中构建在同一分子中包含α和β键的寡糖。此外,由于糖基化可以独立于供体的端基异构体反应性进行,因此不需要通过针对化学选择性糖基化的广泛保护基调节来区分构件的端基异构体反应性。这赋予了构件设计极大的灵活性,使供体与受体匹配,

  • Synthesis and Vaccine Evaluation of the Tumor-Associated Carbohydrate Antigen RM2 from Prostate Cancer

    We have successfully developed a [1+2+3] one-pot strategy to synthesize the RM2 antigen hexasaccharide that was proposed to be a prostate tumor antigen. The structure of the synthetic product was verified by NMR analysis and antibody binding assay using a glycan microarray. In addition, the synthetic antigen was conjugated to a mutated diphtheria toxin (DT, CRM197) with different copy numbers and adjuvant combinations to form the vaccine candidates. After vaccination in mice, we used glycan microarrays to monitor their immune response, and the results indicated that, when one molecule of DT was incorporated with 4.7 molecules of RM2 on average (DT-RM4.7) and adjuvanted with the glycolipid C34, the combination exhibited the strongest anti-RM2 IgG titer. Moreover, the induced mouse antibodies mediated effective complement-dependent cytotoidcity (CDC) against the prostate cancer cell line LNCap.
  • Structural establishment of polygalatenosides A and B by total synthesis

    The first total synthesis of polygalatenosides A (1) and B (2), originally isolated from the traditional Chinese medicine and reported as antidepressant agents, is described here. Glycosylation between thiogalactosyl donors 6 and 7 and 1-deoxyglucosyl acceptor 5 yielded the corresponding key intermediates 10 and 16, respectively, with an alpha(1 -> 2)-glycosidic linkage in moderate yields. In addition, D-configuration of the galactoside residue in 1 and 2 was confirmed in our studies. (c) 2008 Elsevier Ltd. All rights reserved.
  • Synthesis of the tetrasaccharide repeating unit of the O -glycan from the polar flagellum flagellin of Azospirillum brasilense Sp7
    作者:Kumar Bhaskar Pal、Balaram Mukhopadhyay

    日期:2014.12
    Chemical synthesis of the tetrasaccharide repeating unit of the O-glycan from the polar flagellum flagellin of Azospirillum brasilense Sp7 in the form of its p-methoxyphenyl glycoside is reported. The required glycosidic linkages have been accomplished by activation of thioglycosides with N-iodosuccinimide in the presence of H2SO4-silica. H2SO4-silica was found to be an effective alternative to the classical acid promoters like TfOH or TMSOTf and it can lead to the formation of both 1,2-cis and 1,2-trans glycosidic linkages depending on the protecting group manipulation and control of the reaction condition.
