structural moieties related to inhibition of serotonin reuptake, such as benzo[b]thiophene derivatives to arylpiperazines, typical 5-HT(1A) receptor ligands. In binding studies, several compounds showed affinity at the 5-HT transporter and at 5-HT(1A) receptors. Molecular modeling studies predicted the pharmacophore elements required for high affinity binding and the features that enable to discriminate
有人提出5-HT(1A)受体拮抗剂可增强选择性5-羟色胺(5-HT)再摄取抑制剂的抗抑郁功效。为了寻求新型有效的抗抑郁药,设计,合成了1-(芳基)-3- [4-芳基哌嗪-1-基] -1-丙烷分子杂化物,并对其5-HT再摄取抑制和5-HT( 1A)受体亲和力。该设计基于偶联与抑制5-羟色胺再摄取有关的结构部分,例如苯并[b]噻吩衍生物与典型的5-HT(1A)受体配体芳基哌嗪。在结合研究中,几种化合物对5-HT转运蛋白和5-HT(1A)受体表现出亲和力。分子模型研究预测了高亲和力结合所需的药效基团元素,以及能够区分激动剂,部分激动剂,或对5-HT(1A)受体的拮抗作用和对5-HT转运蛋白的抑制。在结合步骤之前,去溶剂化过程中的溶剂相互作用以及焓和人类补偿可能是解释激动剂,部分激动剂和拮抗剂特性的原因。氢键键合能力似乎很重要,可以打破氢螺旋间的氢键或在配体结合后形成其他键。部分激动剂和拮抗剂不能
