A scaffold hopping strategy converted the known 1-[(1-methyl-1H-imidazol-2-yl)methyl]-4-phenylpiperidine core (1 and 2) by cyclization to a fused [6 + 5+6] membered heterocyclic mGluR2 PAM scaffold. Pharmacophore guided structure-activity relationship (SAR) studies resulted in a series of potent and metabolically stable mGluR2 PAMs. A representative optimized compound (95) having the most balanced
支架跳跃策略通过环化将已知的[[1-(1-甲基-1H-咪唑-2-基)甲基] -4-苯基哌啶核心(1和2)转化为稠合的[6 + 5 + 6]杂环mGluR2 PAM脚手架。药理学指导的结构活性关系(SAR)研究导致了一系列有效且代谢稳定的mGluR2 PAM。具有最平衡特征的代表性优化化合物(95)在PCP诱导的小鼠超运动模型中显示了功效,该模型揭示了新的化学型是靶向mGluR2受体的有希望的PAM导联,并为进一步的翻译研究提供了支持。
