Abstract:
Two (11)C-labelled PET tracers, (R)-N-[(11)C]methyl-N-(3,3-dideuteropropargyl)-1-phenylpropan-2-amine ([(11)C]L-deprenyl-D2, [(11)C]DED) and (S)-N-[(11)C]methyl-N-propargyl-1-phenylpropan-2-amine ([(11)C]D-deprenyl, [(11)C]DDE) were synthesised. One step N-alkylation with [(11)C]MeI or [(11)C]MeOTf was performed using the automated platform TRACERlab® FX-C Pro. The labelled products were obtained with (37±15)% (n=10) (end of synthesis, decay corrected from [(11)C]MeI) radiochemical yields from [(11)C]MeI after 38±3min synthesis time. In all cases, radiochemical purity was over 99% when [(11)C]MeOTf was used. This synthesis using a commercial platform makes these tracers more accessible for clinical research purposes.
