D2 receptor/Dopamine D2 receptor in Human (target type: SINGLE PROTEIN) [ChEMBL: CHEMBL217] [GtoPdb: 215] [UniProtKB: P14416]
GtoPdb	β-arrestin 2 biased agonist.	-	7.1	pKi	79	nM	Ki	Proc Natl Acad Sci USA (2011) 108: 18488-93 [PMID:22025698]

ChEMBL	Radioligand Binding Assay: Membranes prepared as above were resuspended to 1 ug protein/ul (measured by Bradford assay using BSA as standard), and 50 ul were added to each well of a polypropylene 96-well plate containing (per well): 50 ul of buffer (20 mM HEPES, 10 mM MgCl2, 1 mM EDTA, 1 mM EGTA, 100 mM N-methyl-D-gluconate, pH 7.4), 50 ul of 1.5 nM [3H]N-methylspiperone (final concentration 0.3 nM) and reference or D2 test ligand at various concentrations ranging from 50 uM to 50 uM (final concentrations ranging from 10 uM to 10 uM, triplicate determinations for each concentration of D2 test ligand). After a 1.5-hr incubation in the dark at room temperature, the reactions were harvested onto 0.3% PEI-soaked Filtermax GF/A filters (Wallac) and washed three times with ice-cold 50 mM Tris, pH 7.4 using a Perkin-Elmer Filtermate 96-well harvester. The filters were subsequently dried, placed on a hot plate (100° C.), and Melitilex-A (Wallac) scintillant was applied.	B	7.12	pKi	75	nM	Ki	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%).

ChEMBL	pERK High-Content Assay: Cell Culture: Chinese Hamster Ovary (CHO) cells stably expressing the hD2L dopamine receptor (Urban et al., Neuropsychopharmacology 32:67 (2007)) were maintained in Ham's F12 medium supplemented with 10% fetal bovine serum, 100 U/mL penicillin, 100 ug/mL streptomycin, and 0.5 ug/ml G418. On day 1 of the assay, cells were seeded onto black clear-bottom tissue culture-treated 96-well plates (Greiner, BioOne). On day 2 of the assay, cells were washed with serum-free medium (Ham's F-12, penicillin and streptomycin) and incubated in 100 uL serum-free medium overnight.Immunofluorescence: Automatic multichannel pipetters were used for liquid handling and multichannel vacuum manifolds for aspirations. Each tested concentration was typically measured in triplicate or quadruplicate. For concentration curves, half-log-dilutions were used. Drug dilutions were prepared in stimulation medium (serum-free medium, 100 mg/L ascorbic acid).	B	7.3	pEC50	50	nM	EC50	US-9156822-B2. Functionally selective ligands of dopamine D2 receptors (2015)
