  The objective of this study was to synthesize and evaluate a novel fluorine-18 labeled deuterium substituted analogue of rasagiline (9, [F-18]fluororasagiline-D-2) as a potential PET radioligand for studies of monoamine oxidase B (MAO-B).The precursor compound (6) and reference standard (7) were synthesized in multi-step syntheses. Radiolabeling of 9 was accomplished by a two-step synthesis, compromising a nucleophilic substitution followed by hydrolysis of the sulfamidate group. The incorporation radiochemical yield from fluorine-18 fluoride was higher than 30%, the radiochemical purity was >99% and the specific radioactivity was >160 GBq/mu mol at the time of administration.In vitro compound 7 inhibited the MAO-B activity with an IC50 of 173.0 +/- 13.6 nM. The MAO-A activity was inhibited with an IC50 of 9.9 +/- 1.1 mu M. The fluorine-18 version 9 was characterized in the cynomolgus monkey brain where a high brain uptake was found (275% SUV at 4 min). There was a higher uptake in the striatum and thalamus compared to the cortex and cerebellum. A pronounced blocking effect (50% decrease) was observed in the specific brain regions after administration of L-deprenyl (0.5 mg/kg) 30 min prior to the administration of 9. Radiometabolite studies demonstrated 40% of unchanged radioligand at 90 min post injection.An efficient radiolabeling of 9 was successfully established and in the monkey brain 9 binds to MAO-B rich regions and its binding is blocked by the selective MAO-B compound L-deprenyl. The radioligand 9 is a potential candidate for human PET studies. (C) 2013 Elsevier Ltd. All rights reserved.
