We synthesized several N-substituted-11-hydroxynoraporphines and their esters of varying chain length, evaluated their binding affinity at dopamine (DA) receptor sites in rat caudate-putamen membranes, and quantified their effects on motor activity in normal adult male rats. The 11-hydroxyaporphines showed similar neuropharmacological properties to the corresponding 10,11-catecholaporphines. At moderate doses, their esters proved to have more prolonged behavioral actions and superior oral bioavailability. (C) 2004 Elsevier Ltd. All rights reserved.
