Abstract Multiple-specificity ligands are considered promising pharmacological tools that may show higher efficacy in the treatment of diseases for which the modulation of a single target is therapeutically inadequate. We prepared a set of novel ligands for D 1 and D 2 dopamine receptors by combining two indolo [2, 3-a] quinolizidine scaffolds with various tripeptide moieties. The binding and functional properties of these molecules were ...
