The present invention is directed to pyrrolopyridine compounds of formula (I)
or their pharmaceutically acceptable salts, 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, this invention relates to a method of using the compounds of this invention 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. The invention further relates to a method of measuring clinical efficacy of therapeutic agents for Alzheimer's disease and other neurodegenerative diseases characterized by tau pathology.
本发明涉及式 (I) 的吡咯并吡啶化合物
或它们的药学上可接受的盐,这些化合物可能适用于 tau 聚集物、b-片状聚集物、β-淀粉样蛋白聚集物或α-突触核蛋白聚集物的成像,因此可用于阿尔茨海默氏症患者中 tau 聚集物的结合和成像。更具体地说,本发明涉及一种在正电子发射断层扫描(PET)成像中使用本发明化合物作为示踪剂的方法,以研究体内大脑中的tau沉积物,从而诊断阿尔茨海默氏症和其他以tau病理学为特征的神经退行性疾病。本发明还涉及一种测量阿尔茨海默病和其他以tau病理学为特征的神经退行性疾病治疗药物临床疗效的方法。
