  • Sugar Mimics:  An Artificial Receptor for Cholera Toxin
    作者:Anna Bernardi、Anna Checchia、Paola Brocca、Sandro Sonnino、Fabio Zuccotto
    DOI:10.1021/ja983567c
    日期:1999.3.1
    paper describes the pseudosugar 2 [Galβ1−3GalNAcβ1−4(NeuAcα2−3)DCCHD], a high affinity binder of cholera toxin (CT). The molecule was designed using molecular modeling techniques to mimic the natural CT membrane receptor, ganglioside GM1. The central residue of GM1, a 3,4-disubstituted galactose unit, was recognized as the ganglioside scaffold element and substituted with a conformationally locked cyclohexanediol
    该论文描述了伪糖 2 [Galβ1−3GalNAcβ1−4(NeuAcα2−3)DCCHD],一种霍乱毒素 (CT) 的高亲和力结合剂。该分子是使用分子建模技术设计的,以模拟天然 CT 膜受体神经节苷脂 GM1。GM1 的中心残基是一个 3,4-二取代的半乳糖单元,被认为是神经节苷脂支架元件,并被构象锁定的环己二醇 (DCCHD) 取代。DCCHD 使用对映选择性 Diels Alder 方法和在赤道位置的区域选择性 α-唾液酸化以对映纯形式合成。用Galβ(1-3)GalNAc供体进行糖基化完成了2的合成。发现2的溶液结构及其与CT的结合能力类似于GM1寡糖的那些。
  • Synthesis of a Pseudo Tetrasaccharide Mimic of Ganglioside GM1
    作者:Anna Bernardi、Giovanna Boschin、Anna Checchia、Maria Lattanzio、Leonardo Manzoni、Donatella Potenza、Carlo Scolastico
    DOI:10.1002/(sici)1099-0690(199906)1999:6<1311::aid-ejoc1311>3.0.co;2-w
    日期:1999.6
    The pseudo tetrasaccharide 2 was designed to mimic ganglioside GM1, the membrane receptor of both the cholera toxin and of the heat-labile toxin of E. coli. Compound 2 retains the Gal and Neu5Ac recognition determinant of GM1 and uses as the scaffold element a new, conformationally restricted cyclohexanediol (DCCHD 3), with the same relative and absolute configuration of natural galactose; The diol 3 was enantioselectively synthesized by an asymmetric Diels-Alder reaction, followed by dihydroxylation of the resulting cyclohexene. Glycosylation of 3 with the sialyl donor 17 and the Gal beta(l-3)GalNAc donor 15, followed by removal of the protecting groups, completed the synthesis of 2.
