Pyrrolopyridine compounds of formula (I) or their pharmaceutically acceptable salts are disclosed, which may be suitable for imaging tau aggregates, b-sheet aggregates, beta-amyloid aggregates or alpha- synuclein aggregates, and hence are useful in binding and imaging tau aggregates in Alzheimer's patients. More specifically, the compounds are used as tracers in positron emission tomography (PET) imaging to study tau deposits in brain in vivo to allow diagnosis of Alzheimer's disease and other neurodegenerative diseases characterized by tau pathology. Futher, the compounds are useful for measuring clinical efficacy of therapeutic agents for Alzheimer's disease and other neurodegenerative diseases characterized by tau pathology.
公开了式(I)的吡咯吡啶化合物或其药学上可接受的盐,这些化合物可能适用于成像tau聚集体、β-折叠聚集体、β-淀粉样聚集体或α-突触核蛋白聚集体,因此在结合和成像阿尔茨海默病患者的tau聚集体方面是有用的。更具体地,这些化合物被用作正电子发射断层扫描(PET)成像中的示踪剂,用于研究体内脑部的tau沉积,以便诊断阿尔茨海默病和其他以tau病理为特征的神经退行性疾病。此外,这些化合物对于测量治疗阿尔茨海默病和其他以tau病理为特征的神经退行性疾病的临床疗效是有用的。
