Synthesis and evaluation of radiolabeled analogs of the antidepressant drug zimelidine as potential SPECT-ligands for the serotonin transporter.

Z-3-(4-bromophenyl)-N,N-dimethyl-3-(3-pyridinyl)-2-propen-1-amine or zimelidine (ZIM) and its first metabolite nor-zimelidine, were radioiodinated via a nonisotopic exchange, using the Cu(I)-assisted nucleophilic labeling method. To evaluate their potential as SPECT ligands for the serotonin transporter (SERT), the biodistribution of both ligands was… (More)
