An efficient synthesis of glycosylamino acid building blocks
containing core 1, core 2, core 3, core 4 or core 6 mucin core
oligosaccharide structures linked O-glycosidically to threonine has been
developed. These building blocks 6, 10, 16, 24 and 30 can be used
directly for coupling reactions in a glycopeptide synthesis. In a
multiple-column solid-phase synthesis, they have been used to prepare
different series of glycopeptides. Decapeptide sequences have been
synthesized from repeating units of the mucins MUC 2 and MUC 3 in which
different threonine residues are each systematically glycosylated with
an oligosaccharide of core 1, core 2, core 3, core 4 or core 6
structure. Glycopeptides are substrates for the study of the
biosynthesis of the saccharide side-chains of mucins.
我们开发出了一种高效合成糖基氨基酸构件的方法,这种构件含有核心 1、核心 2、核心 3、核心 4 或核心 6 与苏氨酸以 O 型糖苷键相连的粘蛋白核心寡糖结构。这些构建模块 6、10、16、24 和 30 可直接用于糖肽合成中的偶联反应。在多柱固相合成中,它们被用来制备不同系列的糖肽。十肽序列是由粘蛋白 MUC 2 和 MUC 3 的重复单元合成的,其中不同的苏氨酸残基分别与核心 1、核心 2、核心 3、核心 4 或核心 6 结构的寡糖系统地糖基化。糖肽是研究粘蛋白糖侧链生物合成的底物。
