The crystal structure of the dopamine D3 receptor (D3R) in complex with eticlopride inspired the design of bitopic ligands that explored (1) N-alkylation of the eticlopride’s pyrrolidine ring, (2) shifting of the position of the pyrrolidine nitrogen, (3) expansion of the pyrrolidine ring system, and (4) incorporation of O-alkylations at the 4-position. Structureactivityrelationships (SAR) revealed
多巴胺 D 3受体 (D 3 R) 与艾可必利复合物的晶体结构启发了双位配体的设计,该设计探索了 (1) 艾可必利吡咯烷环的N-烷基化,(2) 吡咯烷氮位置的移动, (3)吡咯烷环系统的扩展,和(4)在4-位引入O-烷基化。结构活性关系 (SAR) 显示,移动N - 或扩展吡咯烷环不利于 D 2 R/D 3 R 结合亲和力。小吡咯烷N-烷基的耐受性较差,但添加接头和二级药效基团 (SP) 可以改善亲和力。此外,与类似的N-烷基化化合物相比, O-烷基化类似物显示出更高的结合亲和力,例如O-烷基化33 (D 3 R,0.436 nM和D 2 R,1.77 nM)与N-烷基化11 (D 3 R, 6.97 nM 和 D 2 R,25.3 nM)。所有先导分子都是功能性D 2 R/D 3 R 拮抗剂。分子模型证实,4 位修饰对于未来需要长接头和/或空间庞大基团的 D 2 R/D 3 R 生物共轭工具具有良好的耐受性。
