The present invention relates to novel radiolabelled inhibitors of formula I for the Glycine 1 transporter (GlyT1), useful for the labelling and diagnostic imaging of the glycine 1 transporter functionality.
wherein
R1 is isopropoxy or 2,2,2-trifluoro-1-methyl-ethoxy; and
R2 is a radiolabelled group CH3, wherein the radionuclide is 3H or 11C. The radiolabelled compounds of formula I may be used as PET (Positron Emission Tomography) radiotracer for the labelling and diagnostic molecular imaging of the glycine 1 transporter functionality.
本发明涉及一种新型的式I的放射性标记抑制剂,用于Glycine 1转运蛋白(GlyT1)的标记和诊断成像,其中R1是异丙氧基或2,2,2-三氟-1-甲基-乙氧基;R2是一个放射性标记基团CH3,放射性核素为3H或11C。式I的放射性标记化合物可用作PET(正电子发射断层扫描)放射性示踪剂,用于标记和诊断分子成像Glycine 1转运蛋白的功能。
