Reports of a high-affinity ligand for E-selectin, sialyl di-Lewis(x) (sLe(x)Le(x), 1), motivated us to incorporate modifications to previously reported biphenyl-based inhibitors that would provide additional interactions with the protein. These compounds were assayed for the ability to inhibit the binding of sialyl Lewis(x) (sLe(x), 2) bearing HL-60 cells to E-, P-, and L-selectin fusion proteins.
E-选择素的高亲和力配体,唾液酸二-Lewis(x)(sLe(x)Le(x),1)的报道促使我们将对先前报道的基于联苯的抑制剂进行修饰,从而提供与蛋白质。分析了这些化合物抑制带有唾液酸的Lewis(x)(sLe(x),2)HL-60细胞与E-,P-和L-选择蛋白融合蛋白结合的能力。我们报告说,包含简单的非寡糖选择素拮抗剂的多个组成部分的二聚体或三聚体化合物抑制sLe(x)依赖性结合,并具有比单体化合物显着增强的效力。增强的效力与单个选择素凝集素结构域内的其他结合相互作用一致。然而,不能排除与多个凝集素结构域的多价相互作用。
