设计并合成了用于E-选择素拮抗剂的新型N-乙酰基-D-葡萄糖胺(Glc N Ac)模拟物。该模拟物由被岩藻糖部分的连接位置附近的烷基取代基取代的环己烷环组成。掺入E-选择素拮抗剂产生了测试化合物8和2'-苯甲酰化类似物21,在低微摩尔范围内表现出亲和力。通过使用饱和转移差异(STD)-NMR,可以证明亲和力的提高不是由于烷基取代基与目标蛋白E-选择素的疏水性接触,而是由于稳定了其拮抗剂的空间效应所致。生物活性构象。发现在远端位置含有甲基取代基的拮抗剂10和35的亲和力丧失(因此不能支持核心的稳定)进一步支持了该假设。最后,当含有两个甲基取代基的Glc N Ac模拟物(52和53使用),其中一个甲基位于岩藻糖连接位置附近,另一个位于较远位置,亲和力得以恢复。
