Investigation of a novel amino-aza-benzimidazolone structural class of positive allosteric modulators (PAMs) of metabotropic glutamate receptor 2 (mGluR2) identified [2.2.2]-bicyclic amine 12 as an intriguing lead structure due to its promising physicochemical properties and lipophilic ligand efficiency (LLE). Further optimization led to chiral amide 18, which exhibited strong in vitro activity and
新型代谢型谷氨酸受体2(mGluR2)的正构构调节剂(PAMs)的氨基氮杂-苯并咪唑酮结构类别的研究确定了[2.2.2]-双环胺12由于其有前途的理化性质和亲脂性配体而成为引人入胜的铅结构。效率(LLE)。进一步的优化导致了手性酰胺18的出现,它具有很强的体外活性和诱人的药代动力学(PK)特性。假设驱动的目标设计将化合物21确定为有效的,高度选择性的,口服生物利用的mGluR2 PAM,该化合物可解决CYP时间依赖性抑制(TDI)责任为18的问题,同时在临床上保持出色的类药物特性以及强大的体内活性验证的抗精神病药潜力模型。
