Fluorine-18-Labeled Diaryl-azines as Improved β-Amyloid Imaging Tracers: From Bench to First-in-Human Studies
The deposition of β-amyloid (Aβ) in the brain is a pathologic hallmark of Alzheimer’sdisease (AD), appearing years before the onset of symptoms, and its detection is incorporated into clinical diagnosis. Here, we have discovered and developed a class of diaryl-azine derivatives for detecting Aβplaques in the AD brain using PETimaging. After a set of comprehensive preclinical assessments, we screened
大脑中 β-淀粉样蛋白 (Aβ) 的沉积是阿尔茨海默病 (AD) 的病理标志,在症状出现前数年出现,其检测已纳入临床诊断。在这里,我们发现并开发了一类二芳基嗪衍生物,用于使用 PET 成像检测 AD 大脑中的 Aβ 斑块。经过一系列全面的临床前评估后,我们筛选出一种有前途的 Aβ-PET 示踪剂 [ 18 F] 92,它对 Aβ 聚集体具有高结合亲和力,与 AD 脑切片具有显着结合能力,并且在啮齿动物中具有最佳脑药代动力学特性和非人类灵长类动物。首次人体 PET 研究表明 [ 18 F] 92显示出低白质摄取并且可以与 Aβ 病理学结合以区分 AD 和健康对照受试者。所有这些结果都支持 [ 18 F] 92可能成为一种有前途的 PET 示踪剂,用于可视化 AD 患者的 Aβ 病理。
