RADIOLABELLED INHIBITORS OF THE GLYCINE 1 TRANSPORTER

摘要

The present invention relates to novel radiolabelled inhibitors of general 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. It has been found that 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.
