Positron emission tomography (PET) studies of the monoamine neurotransmitter systems in the human brain employ a variety of radiotracers targeting the many receptors, transporters, and enzymes present in monoaminergic neurons. One of these is the vesicularmonoaminetransporter2 (VMAT2), the protein responsible for the energy-dependent accumulation of monoamines into synaptic vesicles. The development of
radiosynthesis and evaluation of the 9-(+)-11C-DTBZ analog, 10-(+)-11C-DTBZ, as a vesicularmonoaminetransporter2 (VMAT2) imaging agent and compare it with 9-(+)-11C-DTBZ. 10-(+)-11C-DTBZ was obtained by 11C-MeI methylation with its 10 hydroxy precursor in the presence of 5 M NaOH. It had a slightly better average radiochemical yield of 35.3 ± 3.6% (decay-corrected to end of synthesis (EOS)) than did
