The synthesis and anion transport properties of a series of transmembrane anion transporters based on an isophthalamide scaffold with phenyl, naphthyl or anthracenyl central rings are reported. Anion transport studies using POPC vesicles, showed that the compounds have Hill coefficients >1. This is indicative of higher order complex formation, evidence that leads us to suggest that the compounds are
报道了一系列基于间苯二甲酰胺骨架并带有苯基,萘基或蒽基中心环的跨膜阴离子转运蛋白的合成和阴离子转运特性。使用POPC囊泡的阴离子迁移研究表明,该化合物的Hill系数> 1。这表明高阶复合物的形成,证据使我们提出这些化合物并非仅作为移动载体发挥作用,而是正在观察到一种协同转运机制。使用荧光光谱法显示化合物在磷脂双层中聚集,这提供了这些化合物充当自组装阴离子传导聚集体的证据。
