prepared and their affinity to 5-HT1A, 5-HT2A and 5-HT2C receptors were 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 and affinity towards serotoninergic receptors. In binding studies, several
制备了与芳基哌嗪部分连接的异烟酰胺衍生物,并评估了它们对5-HT 1A,5-HT 2A和5-HT 2C受体的亲和力。已知在对血清素受体,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合适选择亲和力中起关键作用的结构元件(杂环核,烷基链和4-取代的哌嗪)的组合。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)。N-(3-(4-(双(4-(4-氟苯基)甲基)哌嗪-1-基)丙基)异烟酰胺(4s),Ki = 0.130 nM,是5-HT 1A受体相比活性最高,选择性最高的衍生物对其他5-羟色胺能,多巴胺能和肾上腺素能受体。相反,化合物4o在亚摩尔范围内显示5-HT 2A亲和力值。此外,选择对5-HT 1A和5-HT 2A受体具有更好的亲和力和选择性结合特性的化合物,以便通过体
