A novel set of azabicyclic aryl amides have been identified as potent and selective agonists of the alpha7 nAChR. A two-pronged approach was taken to improve the potential hERG liability of previously disclosed alpha7 nAChR agonist, PNU-282,987, while maintaining the compound's other desirable pharmacological properties. The first approach involved further exploration of the aryl carboxylic acid fragment
一组新的氮杂双环芳基酰胺已被鉴定为α7nAChR的有效和选择性激动剂。采取了两管齐下的方法来改善先前公开的alpha7 nAChR激动剂PNU-282,987的潜在hERG耐受性,同时保持该化合物的其他所需药理特性。第一种方法涉及对PNU-282,987的芳基羧酸片段的进一步研究,而第二种方法则侧重于对PNU-282,987的氮杂双环胺部分的修饰。每个系列中最好的化合物的特点是脑部快速渗透,在大鼠中具有良好的口服生物利用度,并在大鼠P50听觉感觉门控试验中显示出体内功效。每个系列(1h,1o,2a,9a和18a)中至少有一个类似物表现出比PNU-282,987更高的hERG安全性。
