Movement disorders such as Parkinson’s disease and Huntington’s disease are serious life-limiting and debilitating movement disorders. Their onset typically occurs from mid-life to late in life, and effective diagnostic techniques for detecting and following the disease course are lacking. Our goal is to develop receptor imaging agents for positron emission tomography (PET) that selectively target
帕金森病和亨廷顿病等运动障碍是严重的限制生命和使人衰弱的运动障碍。它们的发病通常发生在中年至晚年,并且缺乏用于检测和跟踪病程的有效诊断技术。我们的目标是开发用于正电子发射断层扫描 (PET) 的受体显像剂,它选择性地靶向在纹状体中高度表达的最相关的腺苷受体 (AR) 亚型,即 A 2A AR。为了进一步实现这一目标,我们已经合成并在药理学上表征了一系列高亲和力 A 2A AR 配体,基于已知的拮抗剂 SCH 442416 (R = -Me),其末端具有结构可变性 (R = -Et, -一世-Pr、-allyl 等)。适合用作PET示踪剂的O-氟乙基类似物的K i值为12.4 nM,并且与A 1和A 3 AR相比对A 2A AR具有高度选择性。
