ChEMBL cAMP GloSensor Assay: HEK293T cells co-expressing the cAMP biosensor GloSensor-22F (Promega) and hD2 receptors were seeded (10,000 cells/20 ul/well) into white, clear-bottom, tissue culture plates in HBSS, 10% FBS, 20 mM HEPES, pH 7.4. After a one- to two-hour recovery, cells were treated with 10 ul of 3x test or reference drug prepared in HBSS, 10% FBS, 20 mM HEPES, pH 7.4. After 30 minutes, cells were challenged with 10 ul of 1,200 nM (4x) isoproterenol in 8% (4x) GloSensor reagent. Luminescence per well per second was read on a Wallac TriLux microbeta plate counter. Data were normalized to the isoproterenol response (100%) and the maximal quinpirole-induced inhibition thereof (0%) and regressed using the sigmoidal dose-response function built into GraphPad Prism 4.0. Notably, HEK293T cells expressing the GloSensor-22F alone (no hD2) were assayed in parallel and displayed no inhibition of isoproterenol-stimulated cAMP. B 7.89 pEC50 13 nM EC50 US-9156822-B2.

ChEMBL Beta-Arrestin Recruitment (Tango) Assay: Recruitment of β-arrestin to agonist-stimulated D2 receptors was performed using a previously described Tango-type assay (Barnea et al., Proc. Natl. Acad. Sci. USA 105:64 (2008)). Briefly, HTLA cells stably expressing β-arrestin-TEV protease and a tetracycline transactivator-driven luciferase were plated in 15-cm dishes in DMEM containing 10% fetal bovine serum and transfected (via calcium phosphate) with 20 μg of a D2V2-TCS-tTA construct (Barnea et al., Proc. Natl. Acad. Sci. USA 105:64 (2008)). The next day, cells were plated in white, clear-bottom, 384-well plates (Greiner, 10,000 cells/well, 50 μl/well) in DMEM containing 1% dialyzed fetal bovine serum. The following day, the cells were challenged with 10 μl/well of reference agonist (6 μM) or D2 test ligand (6 μM)±reference agonist prepared in HBS, 20 mM HEPES, pH 7.4, 18% DMSO (final ligand concentrations were 1 μM, final DMSO concentration was 3%).
