The metabotropic glutamate receptor subtype 5 (mGluR5) has been reported to be implicated in various neurological disorders in the central nervous system. To investigate physiological and pathological functions of mGluR5, noninvasive imaging in a living body with PET technology and an mGluR5-specific radiotracer is urgently needed. Here, we report the synthesis of 3-[(18)F]fluoro-5-(2-pyridinylethynyl)benzonitrile ([(18)F]FPEB) through a convenient thermal reaction as a highly specific PET… CONTINUE READING
