H are provided as amyloid imaging agents for detecting brain amyloid deposits as well as other amyloidogenic peptides associated with systemic or localized amyloidosis. Additionally, the compounds are useful for determining if patients, presenting with clinically confusing cases of dementia or presenting with mild cognitive impairment, have Alzheimer's disease. The compounds are additionally useful as surrogate markers for monitoring the efficacy of anti-amyloidosis therapies.
提供至少含有以下可检测标记中的一个的苯并呋喃化合物,所述标记包括131I、123I、124I、76Br、75Br、18F、19F、11C、13C、14C和3H,作为用于检测脑淀粉样沉积物以及与系统性或局部淀粉样病变相关的其他淀粉样肽的淀粉样成像剂。此外,这些化合物可用于确定患有阿尔茨海默病的患者,这些患者表现出临床上令人困惑的痴呆症状或轻度认知障碍。这些化合物还可用作监测抗淀粉样病治疗的有效性的替代标志物。
