details our efforts to develop novel tricyclic muscarinic acetylcholine receptor subtype 4 (M4) positive allosteric modulator (PAM) scaffolds with improved pharmacological properties. This endeavor involved a “tie-back” strategy to replace the 3-amino-5-chloro-4,6-dimethylthieno[2,3-b]pyridine-2-carboxamide core, which led to the discovery of two novel tricyclic cores: an 8-chloro-9-methylpyrido[3′
这封信详细介绍了我们开发新型三环毒蕈碱乙酰胆碱受体亚型 4 (M 4 ) 正变构调节剂 (PAM) 支架的努力,该支架具有改进的药理学特性。这项工作涉及“回接”策略来取代 3-氨基-5-氯-4,6-二甲基噻吩并[2,3- b ]吡啶-2-甲酰胺核心,从而发现了两个新型三环核心:8-氯-9-甲基吡啶并[3',2':4,5]噻吩并[3,2- d ]嘧啶-4-胺核心和8-氯-7,9-二甲基吡啶并[3',2' :4,5]呋喃[3,2- d ]嘧啶-4-胺核心。与母体化合物ML253相比,两种三环核心均表现出针对人 M 4 的低纳摩尔效力,并且大大降低了细胞色素 P450 抑制。
