Effective synthesis of the tetrasaccharide1, substrate for GlcNAc-T II, the pentasaccharide 9, substrate for GlcNAc-T III-V, and the modified analogues 2–8 and 10–14 are developed by linking the corresponding building blocks using the trichloroacetimidate method. The specific modified substrateanalogues 2–8 and 10–14 can be applied to studies of the substrate specificity of GlcNAc-T II and GlcNAc
通过使用三氯乙酰亚氨酸酯方法连接相应的结构单元,开发了有效合成四糖1,GlcNAc-T II的底物,五糖9,GlcNAc-T III-V的底物以及修饰的类似物2-8和10-14的方法。 。特定的修饰底物类似物2-8和10-14可分别用于研究GlcNAc-T II和GlcNAc T III-V的底物特异性。修饰的四糖8和五糖14也可以分别用作GlcNAc-T IV和GlcNAc-T V的潜在特异性底物。
