The synthesis of a new mixed-ligand rhenium complex containing the α-tropanol moiety is reported. The compound is a predecessor to the analogous technetium-99m complex for SPECT imaging of the dopamine transporter in the brain.

A series of rhenium complexes was synthesized as model compounds for the corresponding radioactive technetium-99m complexes for preliminary biological investigations. In a '3+1' mixed-ligand approach the tropanol molecule was linked with the metal core through a ω-mercaptoester group as monodentate ligand. Bis(thioethyl)sulphide was used as the tridentate dithiol ligand to block the remaining free coordination sites. The ω-mercaptoesters were synthesized via the trityl-protected precursors. Binding tests on the cloned human dopamine transporter revealed moderate binding affinities for some of the prepared compounds. The complexes were characterised by X-ray and the lipophilicity as well as pK(a) values were determined. Copyright (C) 1998 Elsevier Science Ltd.
