Since the discovery of the dopamine D-3 receptor, an intensive effort has been directed toward the development of potent and selective ligands in order to elucidate the function and potential therapeutic advantages of targeting D-3 receptors. As a part of our efforts, a novel series of substituted benzolactams derivatives was synthesized mostly through palladium-catalyzed reactions. Their affinities on D-1-D-4 receptors were evaluated and the data led us to highly potent D-3 ligands, some of them highly selective for D-3 receptor, compared to the related dopamine receptor subtypes. Functional D-3 activity assays of the most relevant compounds have been carried out revealing antagonist as well as partial agonist activity. (C) 2010 Elsevier Ltd. All rights reserved.
