Tau 聚集体代表阿尔茨海默病 (AD) 和其他形式的痴呆症的关键病理学。跨定义大脑区域的 Tau 神经原纤维缠结的程度很好地对应于观察到的 AD 认知下降水平。化合物1 ( PI-2620 ) 最近被确定为用于 AD 和非 AD tau 病变的有前途的 Tau 正电子发射断层扫描示踪剂。为了评估N原子位置对 Tau 和脱靶结合的影响,PI-2620的三环核心类似物制备了不同位置的氮原子。使用人 AD 脑匀浆评估对聚集 Tau 的亲和力,并在单胺氧化酶 A (MAO-A) 竞争测定中评估它们的脱靶结合。新型三环核心衍生物均显示出较差的 Tau 结合或 MAO-A 脱靶选择性,表明PI-2620是与 Tau 高亲和力结合和高 MAO-A 选择性的最佳设计。
