The synthesis of three families of sialyl LewisX (sLeX) mimetics based on triazole and bis-triazole scaffolds is reported. The flexibility of these mimetics is dictated by the scaffold and gradually increases from flexible to rigid. All three families were accessible by straightforward synthetic routes and by taking advantage of the unique features and high yields of CuI-catalyzed alkyne–azide cycloaddition
报道了基于三唑和双三唑支架的三族唾液酸 LewisX (sLeX) 模拟物的合成。这些模拟物的柔韧性由支架决定,并逐渐从柔韧增加到刚性。所有三个家族都可以通过简单的合成路线获得,并利用 CuI 催化的炔-叠氮环加成 (CuAAC) 反应的独特特征和高产率。通过使用构象分析(分子动力学)、对接计算和饱和转移差异 (STD) NMR 实验,对糖肽模拟物 12-15 对其对岩藻糖特异性欧洲榆树凝集素 I 的结合亲和力进行了广泛评估。
