CCR5 receptor in a CCL4-dependent manner, but does not compete with [3H]TAK-779 binding at the CCR5. Furthermore, introduction of a p-tolyl moiety at 7-position of the 2-benzazepine scaffold turns the CCR5 PAM 14 into the selective CCR2 receptor antagonist 26b. The structure affinity and activity relationships presented here offer new insights into ligand recognition by CCR2 and CCR5 receptors.
靶向CCR2和CCR5受体被认为是开发新型抗炎药的有前途的概念。在这里,我们介绍了CCR5受体与2-苯并ze庚因支架的第一个探针依赖性正变构调节剂(PAM)的发展。化合物14(2-异丁基-N-([N-甲基-N-(四氢-2H-吡喃-4-基)氨基]甲基}苯基)-1-氧代-2,3-二氢-1H-2- benzazepine-4-carboxamide)以CCL4依赖性的方式激活CCR5受体,但不与CCR5处的[3H] TAK-779结合竞争。此外,在2-苯并ze庚因骨架的7位上引入对甲苯基部分将CCR5 PAM 14变成选择性CCR2受体拮抗剂26b。此处介绍的结构亲和力和活性关系为CCR2和CCR5受体识别配体提供了新的见识。
