dopamine D(2) and D(3) receptor ligands were developed from their potentially bioactive conformation and were compared in order to get insight into molecular properties of importance for D(2)/D(3) receptor selectivity. For the 72 compounds presented here, an extended and more linear conformation in the aliphatic or aryl spacers turned out to be crucial for dopamine D(3) receptor selectivity. Structural
多巴胺D(3)受体被认为是治疗各种神经系统疾病和精神疾病的潜在治疗靶标。针对高亲和力和D(3)与D(2)受体优先的配体,部分激动剂BP 897被视为前导结构。间隔基和芳基部分的变化导致N-烷基化的1-(2-甲氧基苯基)哌嗪具有显着改善的亲和力和选择性。分子建模研究支持结构的发展。多巴胺D(2)和D(3)受体配体的药理模型是从它们潜在的生物活性构象发展而来的,并进行了比较,以便深入了解对于D(2)/ D(3)受体选择性重要的分子特性。对于此处介绍的72种化合物,脂族或芳基间隔基中的扩展和更线性的构象原来是对多巴胺D(3)受体选择性至关重要。芳基部分(苯甲酰胺,杂芳基酰胺,芳基酰亚胺)的结构多样性对(亚)纳摩尔D(3)受体亲和力有重大影响,这是通过更刚性的芳基丙烯酰胺衍生物进行优化的。化合物38(ST 280,(E)-4-碘-N-(4-(4-(2-(甲氧基苯基)哌嗪-1-基)丁基)肉桂酰胺)显
