Picolinamide derivatives, linked to an arylpiperazine moiety, were prepared and their affinity to 5-HT1A, 5-HT2A and 5-HT2C receptors was evaluated. The combination of structural elements (heterocyclic nucleus, alkyl chain and 4-substituted piperazine), known to play critical roles in affinity for serotoninergic receptors, and the proper selection of substituents led to compounds with high specificity
制备了连接至芳基哌嗪部分的吡啶甲酸酰胺衍生物,并评估了它们对5-HT 1A,5-HT 2A和5-HT 2C受体的亲和力。结构元件的组合(杂环核,烷基链和4-取代的哌嗪),已知在对血清素受体的亲和力以发挥关键作用,并导致以高特异性和亲和力向血清素受体的化合物的取代基的正确选择。在结合研究中,几个分子在5-HT 1A,5-HT 2A和5-HT 2C受体的纳摩尔和亚纳摩尔范围内显示出高亲和力,而对其他相关受体(D 1,D 2,α 1和α 2)。Ki = 0.046 nM的N-(2-(4-(嘧啶-2-基)哌嗪-1-基)乙基)吡啶啉酰胺(3o)是5-HT 1A受体的亲和力和选择性最高的衍生物5-羟色胺能的多巴胺能和肾上腺素能受体。N-(2-(4-(2-(2-甲氧基苯基)哌嗪-1-基)乙基)吡啶啉酰胺(3b)显示对5-HT 2A的亚纳摩尔亲和力,Ki = 0.0224 nM,而N-(2-( 4-(双(
