the 5-HT7 receptor, and the 9-carbamoyl moiety afforded increased selectivity. Compound 26j exhibited high affinity for the 5-HT7 receptor, with at least 280-fold selectivity over the 5-HT2 receptor. In a functional model of 5-HT7 receptor activation, this compound was confirmed to have 5-HT7 receptor antagonist activity. It should be a useful tool for clarifying the biological role of the 5-HT7 receptor
制备了一系列四氢苯并吲哚,并评估了这些化合物对5-羟基色胺7(5-HT7)受体和其他受体的亲和力。大多数化合物对5-HT7受体显示出高亲和力,而2a- [4-(四氢吡啶并吲哚-2-基)丁基]四氢苯并吲哚衍生物(26a-j)对该受体具有高选择性。在四氢吡啶并吲哚环的9位上的取代基的性质影响了对5-HT7受体的亲和力,并且9-氨基甲酰基部分提供了增加的选择性。化合物26j显示出对5-HT7受体的高亲和力,其选择性是5-HT2受体的至少280倍。在5-HT7受体活化的功能模型中,证实该化合物具有5-HT7受体拮抗剂活性。
