discovered as a novel D3 ligand with a moderate binding affinity to the D3 receptor (Ki=304 nM) but no selectivity over the D1-like and D2-like receptors. In this study, we wish to report the design, synthesis and structure-activity relationship studies of a series of novel hexahydropyrazinoquinolines. Our efforts resulted in new compounds with improved binding affinity and selectivity. Among them, compound
先前发现六氢吡嗪并喹啉(化合物5c)是对D3受体具有中等结合亲和力的新的D3配体(Ki = 304nM),但是对D1样和D2样受体没有选择性。在这项研究中,我们希望报告一系列新型六氢吡嗪并喹啉的设计,合成和构效关系研究。我们的努力产生了具有改善的结合亲和力和选择性的新化合物。其中,化合物12d对D3受体的结合亲和力的Ki值为2.6 nM,与D1类和D2类受体的选择性分别大于2000倍和99倍,分别代表了有效的D3配体和选择性D3配体。
