Target: D(3) dopamine receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P35462
Assay: Inhibition Assay: 3H]-Spiperone Binding Assay at hD3 and hD4 recombinant receptors CHO cells transiently transfected with human dopamine type 3 or 4 receptors (CHO-hD3 or CHO-hD4, respectively), were re-suspended in 20 mM HEPES, 2 mM EDTA (pH 7.4), homogenised and centrifuged at 40,000 g (20 min, 4° C.). After re-suspension, homogenization and centrifugation as above, the final pellet was re-suspended in 20 mM HEPES, 100 mM NaCl, 10 mM MgCl2, 1 mM EDTA (pH 7.4) and aliquots were kept at −80° C. [3H]-Spiperone Binding experiments were performed in 96 deep-well polypropylene plates in 50 mM Tris/HCl, 120 mM NaCl, 5 mM KCl, 5 mM MgCl2 (pH 7.4). Compounds of invention were serially diluted in DMSO at 100 fold final concentrations in the assay (1% DMSO final in the assay). Displacement was performed in the presence of 0.3 nM [3H]-Spiperone. The reaction was initiated by the addition of membrane suspension (4 μg and 12 μg of protein for CHO-hD3- and CHO-hD4 membranes, respectively) and lasted for 90 or 100 min (for hD3 or hD4 membranes, respectively) at 23° C. in a final volume of 500 μl. Non specific binding (NSB) was determined in the presence of 1 μM Spiperone. The binding reaction was stopped by rapid filtration through GF/B filterplates pre-soaked in 0.5% polyetylenimmine (PEI) using a Packard cell harvester. After washing with ice-cold 0.9% NaCl, the plate was left to dry before the addition of Microscint 20 (50 μl/well, PerkinElmer). Radioactivity was counted with a TopCount (PerkinElmer). Data were analysed by non-linear regression analysis using GraphPad Prism 5.0 (GraphPad Software). Saturation binding experiments were performed similar to the competition binding experiments using a radioligand concentrations ranging from 0.015 to 4.0 nM. Ref: Mackenzie R. G. et al. (1994).

Assay: Functional Calcium Assay: Functional Calcium Assay at hD2 recombinant receptor. CHO cells stably expressing human dopamine receptor type 2, long variant (hD2L), coupled to Gα16 protein (CHO-Gα16-hD2L) were seeded into black walled clear-base 384-well plates at a density of 8,000 cells per well and grown overnight at 37° C. After washing with the assay buffer (20 mM HEPES, 145 mM NaCl, 5 mM KCl, 5.5 mM glucose, 1 mM MgCl2 and 2 mM CaCl2, pH 7.4) containing 2.5 mM Probenecid, cells were incubated with the cytoplasmic Ca2+ probe Fluo-4 AM at 1 μM (final concentration), 37° C. for 60 min. Plates were washed three times as above and placed into a Fluorometric Imaging Plate Reader (FLIPR Tetra, Molecular Devices) to monitor cell fluorescence (ex=470-495 nm, em=515-575 nm) before and after the addition of different concentrations of test compounds. Compounds of invention were dissolved in DMSO and 200-fold diluted with assay buffer plus 0.01% Pluronic F-127. Cells were exposed first to test compounds for 10 min, then to a submaximal concentration of the hD2 receptor agonist dopamine (EC80, 50-140 nM). The fluorescence before compound addition (baseline) and before and after addition of agonist challenge was monitored. The peak of Ca2+ stimulation (baseline subtracted) was plotted versus the concentration of test compound and the curve fitted using a four-parameter logistic equation (XLfit) to assess the agonist/antagonist potency and maximal response.

After re-suspension, homogenization and centrifugation as above, the final pellet was re-suspended in 20 mM HEPES, 100 mM NaCl, 10 mM MgCl2, 1 mM EDTA (pH 7.4) and aliquots were kept at −80° C. [3H]-Spiperone Binding experiments were performed in 96 deep-well polypropylene plates in 50 mM Tris/HCl, 120 mM NaCl, 5 mM KCl, 5 mM MgCl2 (pH 7.4). Compounds of invention were serially diluted in DMSO at 100 fold final concentrations in the assay (1% DMSO final in the assay). Displacement was performed in the presence of 0.3 nM [3H]-Spiperone. The reaction was initiated by the addition of membrane suspension (4 μg and 12 μg of protein for CHO-hD3- and CHO-hD4 membranes, respectively) and lasted for 90 or 100 min (for hD3 or hD4 membranes, respectively) at 23° C. in a final volume of 500 μl. Non specific binding (NSB) was determined in the presence of 1 μM Spiperone. The binding reaction was stopped by rapid filtration through GF/B filterplates pre-soaked in 0.5% polyetylenimmine (PEI) using a Packard cell harvester. After washing with ice-cold 0.9% NaCl, the plate was left to dry before the addition of Microscint 20 (50 μl/well, PerkinElmer). Radioactivity was counted with a TopCount (PerkinElmer). Data were analysed by non-linear regression analysis using GraphPad Prism 5.0 (GraphPad Software). Saturation binding experiments were performed similar to the competition binding experiments using a radioligand concentrations ranging from 0.015 to 4.0 nM. Ref: Mackenzie R. G. et al. (1994).

Assay: Functional Calcium Assay: Functional Calcium Assay at hD2 recombinant receptor. CHO cells stably expressing human dopamine receptor type 2, long variant (hD2L), coupled to Gα16 protein (CHO-Gα16-hD2L) were seeded into black walled clear-base 384-well plates at a density of 8,000 cells per well and grown overnight at 37° C. After washing with the assay buffer (20 mM HEPES, 145 mM NaCl, 5 mM KCl, 5.5 mM glucose, 1 mM MgCl2 and 2 mM CaCl2, pH 7.4) containing 2.5 mM Probenecid, cells were incubated with the cytoplasmic Ca2+ probe Fluo-4 AM at 1 μM (final concentration), 37° C. for 60 min. Plates were washed three times as above and placed into a Fluorometric Imaging Plate Reader (FLIPR Tetra, Molecular Devices) to monitor cell fluorescence (ex=470-495 nm, em=515-575 nm) before and after the addition of different concentrations of test compounds. Compounds of invention were dissolved in DMSO and 200-fold diluted with assay buffer plus 0.01% Pluronic F-127. Cells were exposed first to test compounds for 10 min, then to a submaximal concentration of the hD2 receptor agonist dopamine (EC80, 50-140 nM). The fluorescence before compound addition (baseline) and before and after addition of agonist challenge was monitored. The peak of Ca2+ stimulation (baseline subtracted) was plotted versus the concentration of test compound and the curve fitted using a four-parameter logistic equation (XLfit) to assess the agonist/antagonist potency and maximal response.

UniProt: P35462
Assay: Inhibition Assay: 3H]-Spiperone Binding Assay at hD3 and hD4 recombinant receptors CHO cells transiently transfected with human dopamine type 3 or 4 receptors (CHO-hD3 or CHO-hD4, respectively), were re-suspended in 20 mM HEPES, 2 mM EDTA (pH 7.4), homogenised and centrifuged at 40,000 g (20 min, 4° C.). After re-suspension, homogenization and centrifugation as above, the final pellet was re-suspended in 20 mM HEPES, 100 mM NaCl, 10 mM MgCl2, 1 mM EDTA (pH 7.4) and aliquots were kept at −80° C. [3H]-Spiperone Binding experiments were performed in 96 deep-well polypropylene plates in 50 mM Tris/HCl, 120 mM NaCl, 5 mM KCl, 5 mM MgCl2 (pH 7.4). Compounds of invention were serially diluted in DMSO at 100 fold final concentrations in the assay (1% DMSO final in the assay). Displacement was performed in the presence of 0.3 nM [3H]-Spiperone. The reaction was initiated by the addition of membrane suspension (4 μg and 12 μg of protein for CHO-hD3- and CHO-hD4 membranes, respectively) and lasted for 90 or 100 min (for hD3 or hD4 membranes, respectively) at 23° C. in a final volume of 500 μl. Non specific binding (NSB) was determined in the presence of 1 μM Spiperone. The binding reaction was stopped by rapid filtration through GF/B filterplates pre-soaked in 0.5% polyetylenimmine (PEI) using a Packard cell harvester. After washing with ice-cold 0.9% NaCl, the plate was left to dry before the addition of Microscint 20 (50 μl/well, PerkinElmer). Radioactivity was counted with a TopCount (PerkinElmer). Data were analysed by non-linear regression analysis using GraphPad Prism 5.0 (GraphPad Software). Saturation binding experiments were performed similar to the competition binding experiments using a radioligand concentrations ranging from 0.015 to 4.0 nM. Ref: Mackenzie R. G. et al. (1994).
