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。

The present invention provides bifunctional compounds that efficiently dephosphorylate certain phospho-activated target proteins. Such target proteins can be any protein involved in the pathway of a disease or disorder, such as but not limited to cancer, neurodegeneration, metabolic disease, diabetes, insulin resistance, and so forth.

Structure-activity relationship around PI-2620 highlights the importance of the nitrogen atom position in the tricyclic core
Tau aggregates represent a critical pathology in Alzheimer’s disease (AD) and other forms of dementia. The extent of Tau neurofibrillary tangles across defined brain regions corresponds well to the observed level of cognitive decline in AD. Compound 1 (PI-2620) was recently identified as a promising Taupositronemissiontomographytracer for AD and non-AD tauopathies. To evaluate the impact of the
