A focused library of novel 2,3-dihydro-1H-1,5-benzodiazepin-2-ones containing sites for C-11-, F-18- and I-123-labelling have been prepared and evaluated against membrane expressing human recombinant metabotropic glutamate 2 receptor (mGluR2). The compounds were found to be non-competitive antagonists with nanomolar affinity. HPLC evaluation of the physiochemical properties of these compounds identified two candidates for PET and SPECT imaging of mGluR2.
