series of bitopic derivatives as dopamine D3R ligands. A number of these new compounds show a high binding affinity for D3R with excellent selectivity. Compound (1R,2R)-22e and its enantiomer (1S,2S)-22e show a comparable binding affinity for the D3R, but the former is a potent D3R agonist, while the latter acts as an antagonist. Molecular docking studies revealed different binding poses of the PCPMA
据报道2-苯基环丙基甲胺(PCPMA)类似物是选择性5-羟色胺2C激动剂。在相同的支架的基础上,我们设计并合成了一系列多巴胺D3R配体的双位衍生物。这些新化合物中的许多对D3R表现出很高的结合亲和力,并且具有出色的选择性。化合物(1R,2R)-22e及其对映异构体(1S,2S)-22e对D3R表现出相当的结合亲和力,但前者是有效的D3R激动剂,而后者则充当拮抗剂。分子对接研究表明,DPM的正构结合口袋中PCPMA部分的结合姿势不同,这可能解释了对映异构体的不同功能。化合物(1R,2R)-30q对D3R具有高结合亲和力(Ki = 2.2 nM),并且具有良好的选择性,以及良好的生物利用度和小鼠的脑部渗透特性。这些结果表明,PCPMA支架可作为胺能GPCR配体设计的优先支架。
