The aim of this study was to develop highly specific radiofluorinated ligands for quantitative positron emission tomography (PET) imaging of monoamine oxidase-B (MAO-B) in brain. A series of 8 fluoro derivatives of 1-cinnamyl-4-arylpiperazine were synthesized by standard methods of organic synthesis. The affinity of the compounds was determined in a competitive binding assay using L-[3H] deprenyl as radioligand on rat brain homogenates. The KD of the radioligand was determined by homologous competition. An efficient, three-step procedure for the synthesis of the potential MAO-B ligands was developed. A competitive binding assay was established, using L-[3H]deprenyl as the radioligand, and rat brain membrane homogenate. The compounds were screened (three concentrations 10-9, 10-7 and 10-5) for their MAO-B affinity. We successfully synthesized a series of fluorinated MAO-B ligands. Unfortunately, their affinities toward MAO-B have proved to be rather low. To increase the affinity further... modifications are needed.
