Benzofuran compounds which contain at least one detectable label selected from the group consisting of 131I, 123I, 124I, 125I, 76Br, 75Br, 18F, 19F, 11C, 13C, 14C and 3H 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的苯并呋喃化合物:131I、123I、124I、125I、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,这些化合物还可用于确定患有临床混淆的痴呆症状或轻度认知障碍的患者是否患有阿尔茨海默病。这些化合物还可作为监测抗淀粉样病变治疗疗效的替代标记。
