  吲唑芳基磺酰胺作为变构CC趋化因子受体4（CCR4）拮抗剂的合成及其构效关系

  摘要：

  合成了一系列吲唑芳基磺酰胺，并作为人CCR4拮抗剂进行了研究。含甲氧基或羟基的是更有效的吲唑C4取代基。在C5，C6或C7处只容忍少数人，优选C6类似物。最有效的N 3取代基是5-氯噻吩-2-磺酰胺。具有α-氨基-3-[（甲基氨基）酰基]-基团的N 1间位取代的苄基是最有效的N 1取代基。强碱性氨基在体内的口服吸收率低。诸如吗啉之类的碱性较低的类似物具有良好的口服吸收。但是，它们的间隙也很高。在两个物种中吸收最强的化合物是类似物6（GSK2239633A），已被选择进行进一步开发。芳基磺酰胺拮抗剂在表示为位点II的细胞内变构位点结合CCR4。对两个吲唑磺酰胺片段的X射线衍射研究表明，在活性构象中存在重要的分子内相互作用。
