A scaffold hopping exercise from a monocyclic mGlu NAM with poor rodent PK led to two novel heterobicyclic series of mGlu NAMs based on either a functionalized pyrazolo[1,5- a]pyrimidine-5-carboxamide core or a thieno[3,2- b]pyridine-5-carboxamide core. These novel analogues possess enhanced rodent PK, while also maintaining good mGlu NAM potency, selectivity (versus mGlu and the remaining six mGlu receptors), and high CNS penetration. Interestingly, SAR was divergent between the new 5,6-heterobicyclic systems.
从一个单环 mGluNAM(具有较差的啮齿动物 PK)开始进行支架跳跃实验,导致了两个新的基于功能化吡唑并[1,5-a]嘧啶-5-甲酰胺核心或噻吩并[3,2-b]吡啶-5-甲酰胺核心的异双环 mGluNAM 系列。这些新型类似物具有增强的啮齿动物 PK,同时保持良好的 mGluNAM 效力、选择性(与 mGlu 和其余六个 mGlu 受体相比)和高中枢神经系统穿透性。有趣的是,新的 5,6-杂双环系统的 SAR 存在差异。
