connecting the sugar to one asparagine residue of the protein. We herein report NMR- and modelling-based data on glycomimetics containing α-glycosidic linkages. The bioactivity of α-Gal-containing glycopeptides has been documented by revealing binding to two plant lectins, i.e. a potent β-trefoil toxin (Viscum album agglutinin) and β-sandwich lectin (Erythrina corallodendron agglutinin), by NMR protocols
天然的N-糖基化涉及将糖与蛋白质的一个天冬酰胺残基连接的β-异头键。我们在此报告了关于含α-糖苷键的糖模拟物的基于NMR和建模的数据。已通过NMR方案揭示了与两种植物凝集素(即有效的β-三叶毒素(Viscum Album agglutinin)和β-sandwichlectin凝集素(Erythrinacorallodendron agglutinin))的结合,从而证明了含α-Gal的糖肽的
生物活性。扩展坞提供了对所得复合物的3D结构的见解。这些结果提供了将α-取代的新糖肽引入支架工具箱以设计有效的凝集素
抑制剂的基础。
