with a 3-F in the linker between the primary pharmacophore (PP) and secondary pharmacophore (SP). Among the 3-F-compounds, 9b demonstrated the highest D3R binding affinity (Ki = 0.756 nM) and was 327-fold selective for D3R over D2R. In addition, modification of the PP or SP with a 3,4-(methylenedioxy)phenyl group was also examined. Further, an enantioselective synthesis as well as chiral HPLC methods were
多巴胺 D 3受体 (D 3 R) 在包括物质使用障碍 (SUD) 在内的神经精神疾病中起关键作用。最近,我们报道了一系列N- (3-羟基-4-(4-苯基哌嗪-1-基)丁基)-1 H-吲哚-2-甲酰胺类似物作为高亲和力和选择性的 D 3 R 先导分子用于治疗阿片类药物使用障碍 (OUD)。进一步优化导致一系列类似物在主要药效团 (PP) 和次要药效团 (SP) 之间的接头中用 3-F 代替 3-OH。在 3-F 化合物中,9b表现出最高的 D 3 R 结合亲和力(K i= 0.756 nM),对 D 3 R的选择性比对 D 2 R的选择性高 327 倍。此外,还检查了用 3,4-(亚甲二氧基)苯基对 PP 或 SP 的修饰。此外,还开发了对映选择性合成和手性 HPLC 方法,以得到四种先导化合物的对映纯R - 和S - 对映异构体。脱靶结合亲和力、功能功效和代谢谱揭示了 D 3 R 选择性
