Herein we describe the discovery and optimization of a new series of 2,3-disubstituted and 2,3,6-trisubstituted muscarinic acetylcholine receptor 4 (M4 ) positive allosteric modulators (PAMs). Iterative libraries enabled rapid exploration of one-dimensional structure-activity relationships (SAR) and identification of potency-enhancing heterocycle and N-alkyl pyrazole substituents. Further optimization
在此,我们描述了一系列新的2,3-二取代和2,3,6-三取代毒蕈碱乙酰胆碱受体4(M4)正变构调节剂(PAMs)的发现和优化。迭代库使您能够快速探索一维结构-活性关系(SAR),并鉴定出增强效价的杂环和N-烷基吡唑取代基。进一步的优化导致鉴定出有效的,受体亚型选择性,脑渗透性工具化合物24(7- [3- [1-[([1-氟环戊基)甲基]吡唑-4-基] -6-甲基-2 -吡啶基] -3-甲氧基肉桂啉)。它在临床前测定中可有效预测抗精神病作用,可在大鼠和小鼠中产生剂量依赖性的苯丙胺诱导的运动过度,但在M4基因敲除小鼠中则无效。
