Native sulfatides, as well as many sulfated glycolipids, have been shown to avidly bind to the selectin receptors. In vivo, native sulfatides significantly block activity in selectin-dependent inflammatory responses. The fact that nonsulfated galactocerebrosides did not inhibit selectin-mediated adhesion identified a critical role for the anionic sulfate residue. We therefore initiated a program to
天然的硫化物以及许多硫酸化的糖脂已被证明与选择素受体紧密结合。在体内,天然硫化物显着阻断选择蛋白依赖性炎症反应的活性。未硫酸化的半乳糖苷没有抑制选择素介导的粘附这一事实确定了阴离子硫酸盐残基的关键作用。因此,我们启动了一个程序来评估位置异构体的活性。这项研究显示了对碳水化合物环上硫酸根基团的2和3位的结合选择性以及对二硫化类似物的增强活性。此外,已经发现,亲脂性取代基在碳水化合物环上的附着是可容忍的,这与结合活性中亲脂性口袋的存在相一致。
