Microwave-mediated N-arylation of 4-chloroquinazolines in THF/H2O rapidly and efficiently afforded a library of novel 6-halo-2-phenyl-substituted 4-anilinoquinazolines. The methodology was compatible with numerous ortho-, meta-, and para-substituted N-methylanilines as well as substituted anilines and furnished the corresponding 4-anilinoquinazolines in good yields. Preliminary screening of the synthesized

radiotracer to image microtubules in vivo in the mousebrain. The aim of the present study was to assess the reproducibility of [11C]MPC-6827 PET imaging in non-human primate brains. Two dynamic 0–120 min PET/CT imaging scans were performed in each of four healthy male cynomolgus monkeys approximately one week apart. Time activity curves (TACs) and standard uptake values (SUVs) were determined for whole brains
微管的失调通常与几种精神和神经系统疾病有关,包括成瘾和阿尔茨海默病。使用正电子发射断层扫描 (PET) 对体内微管进行成像可以提供有关它们在疾病发病机制发展中的作用的有价值的信息,并有助于改进治疗方案。我们开发了 [11C]MPC-6827,这是第一个在小鼠大脑中对体内微管进行成像的脑穿透 PET 放射性示踪剂。本研究的目的是评估 [11C]MPC-6827 PET 成像在非人类灵长类动物大脑中的可重复性。对四只健康雄性食蟹猴中的每只进行两次动态 0-120 分钟 PET/CT 成像扫描,大约相隔一周。确定整个大脑和大脑特定区域的时间活动曲线 (TAC) 和标准摄取值 (SUV),并在“测试”和“重新测试”数据之间进行比较。[11C]MPC-6827 在非人类灵长类动物的大脑中表现出出色的脑吸收和良好的药代动力学,测试和重新测试扫描数据之间存在显着相关性 (r = 0.77, p = 0.

potential of an MT imaging agents, no PETligand is currently available for in vivo imaging of MTs in the brain. We radiolabeled [11C]MPC-6827, a high affinity MTA, and demonstrated its specific binding in rat and mice brain using PET imaging. Our experiments show that [11C]MPC-6827 has specific binding to MT in brain, and it is the first MT-binding PETligand.
