building blocks. A p-(benzoyl)-benzyl glycoside was used as a novel anomeric protecting group, which could be selectively removed at a late stage in the synthesis, thus offering the benefit of enhanced flexibility. The artificial aminopropyl moiety was modified by a thioacetyl group, which allowed an efficient conjugation to keyhole limpet hemocyanin (KLH) that had been activated with electrophilic
通过人工氨丙基间隔基修饰的Lewis(y)-Lewis(x)七糖是通过采用两个正交保护的乳糖胺结构单元的方法合成的。对-(苯甲酰基)-苄基糖苷用作新型的端基保护基,可以在合成的后期选择性地将其除去,因此具有增强柔韧性的优点。人工氨基丙基部分被硫代乙酰基修饰,从而可以有效键合已被亲电子的3-(溴乙酰胺基)-丙酰基活化的匙孔血蓝蛋白(KLH)。用Le(y)Le(x)-BrAc-KLH抗原免疫小鼠。通过ELISA对血清进行分析,发现针对Le(y)Le(x)糖产生了强大的辅助性T细胞免疫应答。
