Radiosynthesis and characterization of astemizole derivatives as lead compounds toward PET imaging of τ-pathology
摘要:
由微管相关 tau 蛋白组成的神经纤维缠结是包括阿尔茨海默病在内的一系列神经退行性疾病的标志。因此,神经纤维缠结的体内成像是目前正电子发射断层扫描研究的重点。本文报告了利用合成聚集体作为神经纤维缠结模型的体外放射性配体结合试验的开发情况,以及对 tau 蛋白配体 astemizole 新型衍生物的评估。

A rapid and efficient protocol to afford the title compound 2-[18F]-fluoro-2,2-difluoroethyl tosylate ([18F]7b) is described. Starting from [18F]fluorideion, labelling reagent 7b was obtained in good yields and a high specific radioactivity. Compound ([18F]7b) was then used to synthesise a prospective radiotracer for PET-imaging in dementia.
