of GPR88 as a novel drug target for psychiatric and neurodegenerative disorders. Examination of structure–activity relationships of two known agonist scaffolds 2-PCCA and 2-AMPP, as well as the recently resolved cryo-EM structure of 2-PCCA-bound GPR88, led to the design of a new scaffold based on the “reversed amide” strategy of 2-AMPP. A series of novel (4-substituted-phenyl)acetamides were synthesized
鉴于 GPR88 有望成为精神和神经退行性疾病的新型药物靶点,孤儿受体 GPR88 合成激动剂的开发最近引起了极大的兴趣。检查两种已知的激动剂支架 2-PCCA 和 2-AMPP 的构效关系,以及最近解析的 2-PCCA 结合的 GPR88 的冷冻电镜结构,导致基于 2-AMPP 的“反向酰胺”策略设计了一种新的支架。合成了一系列新型(4-取代-苯基)乙酰胺,并在 cAMP 积累测定中作为 GPR88 激动剂进行评估,这导致发现了几种与 2-AMPP 具有更好或相当效力的化合物。计算对接研究表明,这些新型 GPR88 激动剂与 2-PCCA 占据的 GPR88 变构位点结合。总的来说,我们的研究结果为 GPR88 变构位点的结构见解和 SAR 需求以及 GPR88 变构激动剂的进一步开发提供了新的支架。
