Binding
Competition Binding Assay: The affinity of the compounds described herein was determined by competition binding assays similar to those described in Ryman-Rasmussen et al., Differential activation of adenylate cyclase and receptor internalization by novel dopamine D1 receptor agonists, Molecular Pharmacology 68(4):1039-1048 (2005). This radioligand binding assay used [3H]-SCH23390, a radiolabeled D1 ligand, to evaluate the ability of a test compound to compete with the radioligand when binding to a D1 receptor.D1 binding assays were performed using over-expressing LTK human cell lines. To determine basic assay parameters, ligand concentrations were determined from saturation binding studies where the Kd for [3H]-SCH23390 was found to be 1.3 nM. From tissue concentration curve studies, the optimal amount of tissue was determined to be 1.75 mg/mL per 96 well plate using 0.5 nM of [3H]-SCH23390. These ligand and tissue concentrations were used in time course studies to determine linearity and equilibrium.
