A series of compounds containing privileged scaffolds of the known histamine H-1 receptor antagonists cetirizine, mianserin, ketotifen, loratadine, and bamipine were synthesized for further optimization as ligands for the related biogenic amine binding dopamine D-3 receptor. A pharmacological screening was carried out at dopamine D-2 and D-3 receptors. In the preliminary testing various ligands have shown moderate to high affinities for dopamine D-3 receptors, for example, N-(4-4-[benzyl(phenyl)amino]piperidin-1-yl} butylnaphthalen-2-carboxamide (19a) (hD(3) K-i = 0.3 nM; hD(2) K-i = 703 nM), leading to a selectivity ratio of 2343.
