This Letter describes the synthesis and optimization of a series of heteroaryl-pyrrolidinone positive allosteric modulators (PAMs) of the muscarinic acetylcholine receptor M1 (mAChR M1). Through the continued optimization of M1 PAM tool compound VU0453595, with a focus on replacement of the 6,7-dihydro-5H-pyrrolo[3,4-b]pyridin-5-one with a wide variety of alternative 4,5-dihydropyrrolo-fused heteroaromatics
这封信描述了毒蕈碱乙酰胆碱受体 M 1 (mAChR M 1 )的一系列杂芳基吡咯烷酮正变构调节剂 (PAM) 的合成和优化。通过对 M 1 PAM 工具化合物 VU0453595 的持续优化,重点是将 6,7-dihydro-5 H -pyrrolo [3,4- b ]pyridin-5-one 替换为多种替代品 4,5 -二氢吡咯并稠合的杂芳烃,公开了具有结构新颖化学型的M 1 PAM的产生。这些子系列中的两种化合物8b (VU6005610) 和20a (VU6005852) 对 M 1 mAChR显示出稳健的选择性,而对 M1激动。两种化合物在体外 都具有良好的初步 PK 曲线;图8b还展示了啮齿动物IV盒模型中的高脑暴露。
