series of more integrated and “drug-like” dual acting molecules, incorporating ropinirole as a dopamine D2 receptor agonist and ZM 241385 as an adenosine A2A receptor antagonist. The best compounds of our series maintained the potency of the original pharmacophores at both receptors (adenosine A2A and dopamine D2). In addition, the integrated dual acting ligands also showed promising results in preliminary
药物发现中相对较新的策略是双作用配体的开发。这些分子潜在地能够同时在异二聚体的两个正构结合位点相互作用,可能导致增强的亚型选择性,更高的亲和力,增强或改变的生理反应,以及减少对多种药物给药方案的依赖。在这项研究中,我们成功合成了一系列经典的异二价配体以及一系列更加整合和“类药物”双作用分子,其中纳入了罗匹尼罗作为多巴胺D 2受体激动剂和ZM 241385作为腺苷A 2A受体拮抗剂。我们系列中最好的化合物在两个受体上都保持了原始药效基团的效力(腺苷A2A和多巴胺D 2)。此外,整合的双重作用配体在初步的血脑屏障通透性测试中也显示出令人鼓舞的结果,而经典的异二价配体可能更适合用作药理学工具。
