Abstract

In this study, novel specific PET radioligands containing the 4-(4-fluorobenzyl) piperidine moiety and selectively antagonistic for the NR2B subunit containing NMDA receptors were developed. Two antagonists, RGH-896 (1a) and 4-(4-fluorobenzyl) piperidinyl-1-methyl-2- benzimidazol-5-ol (2a), belonging to two different structural families, were radiolabeled by an aromatic nucleophilic radiofluorination followed by a reduction of the para-position ...
