A series of new benzimidazole-arylpiperazine derivatives III were designed, synthesized and evaluated for binding affinity at serotoninergic 5-HT(1A) and 5-HT(3) receptors. Compound IIIc was identified as a novel mixed 5-HT(1A)/5-HT(3) ligand with high affinity for both serotonin receptors and excellent selectivity over alpha(1)-adrenergic and dopamine D(2) receptors. This compound was characterized
设计,合成和评估了一系列新的苯并咪唑-芳基哌嗪衍生物III,对5-羟色胺能5-HT(1A)和5-HT(3)受体的结合亲和力。化合物IIIc被确定为一种新型的混合5-HT(1A)/ 5-HT(3)配体,对5-羟色胺受体具有很高的亲和力,并且对α(1)-肾上腺素和多巴胺D(2)受体具有优异的选择性。该化合物被表征为在5-HT(1A)Rs和5-HT(3)R拮抗剂的部分激动剂,并且在被动回避学习测试中有效预防毒蕈碱受体阻滞诱导的认知缺陷。
