  high uptake to regions enriched with MAGL. PET imaging of wild-type and MAGL-deficient mice as well as a macaque monkey indicated that [18F]5 ((4 R)-1-3-[2-(18F)fluoro-4-methylpyridin-3-yl]phenyl}-4-[4-(1,3-thiazol-2-ylcarbonyl)piperazin-1-yl]pyrrolidin-2-one, [18F]T-401) specifically binds to MAGL with adequate reversibility, yielding a high contrast for MAGL within an appropriate imaging time.

  单酰基甘油脂肪酶（MAGL）是一种参与内源性大麻素和炎症信号的胞浆丝氨酸水解酶。MAGL的正电子发射断层扫描（PET）成像可用于验证治疗性MAGL抑制剂的靶向作用以及研究正常和疾病条件下的MAGL水平。但是，迄今尚无可用于MAGL定量评估的具有可逆的MAGL结合动力学的PET放射性配体。在这项研究中，我们设计和合成了含氟的PET探针，该探针从最近鉴定出的可与MAGL可逆结合的哌嗪基吡咯烷-2-一衍生物开始。通过调整分子的亲脂性以优化非特异性结合和血脑屏障通透性，我们成功地鉴定出两种化合物对富含MAGL的区域具有高吸收性。
