selectivity for the D3 receptor. The N-alkyl analogues constitute a homologous series from N-pentyl to N-decyl to probe the length/bulk tolerance of the secondary binding pocket of the D3 receptor. Enantiomeric 3-(3-hydroxyphenyl)pyrrolidine analogues were also prepared in order to test the chirality preference of the orthosteric binding site for this scaffold. Benzamide analogues were prepared to enhance
已经合成了一系列结合了N-烷基和N-丁基酰胺连接的苯甲酰胺官能团的3-(3-羟苯基)吡咯烷类似物,并且已经评估了它们在人多巴胺受体上的体外结合亲和力。我们的配体设计策略是采用3-(3-羟苯基)吡咯烷骨架并将功能性从正构结合位点扩展至第二结合口袋,以增强对D 3受体的亲和力和选择性。所述Ñ烷基类似物构成来自同源系列Ñ戊到Ñ癸基来探测d的二级结合口袋的长度/散装公差3受体。为了测试正构结合位点对该支架的手性偏好,还制备了对映体3-(3-羟苯基)吡咯烷类似物。基于同源系列的结果,制备了苯甲酰胺类似物以增强亲和力和/或选择性。
