The discovery of a new series of selective and high-affinity alpha(1)-adrenoceptor (alpha(1)-AR) ligands, characterized by a 1H-pyrrolo[2,3-d]pyrimidine-2,4(3H,7H)-dione system, is described in this paper. Some synthesized compounds, including 20, 22, and 30, displayed affinity in the nanomolar range for alpha(1)-ARs and substantial selectivity with respect to 5-HT1A and dopaminergic D-1 and D-2 receptors. Functional assays, performed on selected derivatives, showed antagonistic properties. (c) 2005 Elsevier Ltd. All rights reserved.
