mainly conferred by LRRK2 mutations that bring about increased kinase activity. As a consequence, selective inhibition of LRRK2 may help to recover the normal functions of LRRK2, thereby serving as a promising alternative therapeutic target for PD treatment. The mapping of LRRK2 by positron emission tomography (PET) studies allows a thorough understanding of PD and other LRRK2-related disorders; it also
富含亮氨酸的重复激酶2(LRRK2)是参与帕金森氏病(PD)发病机理的一种大蛋白。已经证实PD主要由带来激酶活性增加的LRRK2突变赋予。结果,选择性抑制LRRK2可能有助于恢复LRRK2的正常功能,从而成为有前途的PD治疗替代治疗靶点。通过正电子发射断层扫描(PET)研究对LRRK2进行定位,可以全面了解PD和其他与LRRK2相关的疾病。它还有助于验证和翻译新型LRRK2抑制剂。但是,在原始文献中尚未报道LRRK2 PET探针。本文中,我们提出了[11 C] GNE-1023的简便合成和初步评估,它是用于PD中LRRK2成像的新型强效PET探针。[11 C] GNE-1023的合成具有良好的放射化学收率(10%未经衰变校正的RCY),优异的放射化学纯度(> 99%)和高的摩尔活度(> 37 GBqμmol-1)。[11 C] GNE-1023对LRRK2的出色的体外结合特异性已通过放射自
