1H-indole (2), a series of related arylpiperazin-4-yl-cyclohexyl indole analogs were synthesized then evaluated as 5-HT transporter inhibitors and 5-HT(1A) receptor antagonists. The investigation of the structure-activity relationships revealed the optimal pharmacophoric elements required for activities in this series. The best example from this study, 5-(piperazin-1-yl)quinoline analog (trans-20)
根据先前报道的发现线索,3-(顺-4-(4-(4-(1H-吲哚-4-基)哌嗪-1-基)环己基)-5-氟-1H-吲哚(2),一系列合成了相关的芳基哌嗪-4-基-环己基吲哚类似物,然后将其评估为5-HT转运蛋白抑制剂和5-HT(1A)受体拮抗剂。对结构-活性关系的研究揭示了该系列活动所需的最佳药效学元素。该研究的最佳实例5-(哌嗪-1-基)喹啉类似物(trans-20)在5-HT转运蛋白(K(i)= 4.9nM),5-HT(1A)受体上表现出相同的结合亲和力(K(i)= 6.2nM)并起5-HT(1A)受体拮抗剂的作用。
