| ChEMBL | [3H]-Epibatidine Radioligand Binding Assay: Briefly, cultured cells at >80% confluence were removed from their flasks (80 cm^2) with a disposable cell scraper and placed in 10 mL of 50 mM Tris.HCl buffer (pH 7.4, 4 °C.). The cell suspension was centrifuged at 10,000×g for 5 min and the pellet was collected. The cell pellet was then homogenized in 10 mL buffer with a polytron homogenizer and centrifuged at 36,000 g for 10 min at 4 °C. The membrane pellet was resuspended in fresh buffer, and aliquots of the membrane preparation were used for binding assays. The concentration of [3H]-epibatidine used was ~500 pM for competition binding assays. Nonspecific binding was assessed in parallel incubations in the presence of 300 μM nicotine. Bound and free ligands were separated by vacuum filtration through Whatman GF/C filters treated with 0.5% polyethylenimine. The filter-retained radioactivity was measured by liquid scintillation counting. Specific binding was defined as the difference between total binding and nonspecific binding. Data from competition binding assays were analyzed using Prism 5 (GraphPad Software, San Diego, Calif.). The Kd values for [3H]-epibatidine used for calculating Ki values of nAChR subtypes were 0.02 nM for α2β2, 0.08 nM for α2β4, 0.03 nM for α3β2, 0.3 nM for α3β4, 0.04 nM for α4β2, 0.09 nM for α4β4, 1.8 nM for α7 and 0.05 for rat forebrain. | B | 7.92 | pKi | 12 | nM | Ki | US-9303017-B2. 2,5-disubstituted-pyridyl nicotinic ligands, and methods of use thereof (2016) |

| ChEMBL | [3H]-Epibatidine Radioligand Binding Assay: Briefly, cultured cells at >80% confluence were removed from their flasks (80 cm^2) with a disposable cell scraper and placed in 10 mL of 50 mM Tris.HCl buffer (pH 7.4, 4 °C.). The cell suspension was centrifuged at 10,000×g for 5 min and the pellet was collected. The cell pellet was then homogenized in 10 mL buffer with a polytron homogenizer and centrifuged at 36,000 g for 10 min at 4 °C. The membrane pellet was resuspended in fresh buffer, and aliquots of the membrane preparation were used for binding assays. The concentration of [3H]-epibatidine used was ~500 pM for competition binding assays. Nonspecific binding was assessed in parallel incubations in the presence of 300 μM nicotine. Bound and free ligands were separated by vacuum filtration through Whatman GF/C filters treated with 0.5% polyethylenimine. The filter-retained radioactivity was measured by liquid scintillation counting. Specific binding was defined as the difference between total binding and nonspecific binding. Data from competition binding assays were analyzed using Prism 5 (GraphPad Software, San Diego, Calif.). The Kd values for [3H]-epibatidine used for calculating Ki values of nAChR subtypes were 0.02 nM for α2β2, 0.08 nM for α2β4, 0.03 nM for α3β2, 0.3 nM for α3β4, 0.04 nM for α4β2, 0.09 nM for α4β4, 1.8 nM for α7 and 0.05 for rat forebrain. | B | 6.96 | pKi | 110 | nM | Ki | US-9303017-B2. 2,5-disubstituted-pyridyl nicotinic ligands, and methods of use thereof (2016) |

| ChEMBL | Functional Assay: IC50(10′): The functional properties of the ligands were determined by 86Rb+ efflux assays in cells expressing α3β4 and α4β2 nAChR subtypes. The functional activity of each ligand was measured for its agonism, antagonism and desensitization ability. Agonist activity for each of the ligands was tested at eight different concentrations. The responses were compared to that stimulated by 100 μM (−)-nicotine, a near maximally effective concentration. The potency (IC50(0′)) of each ligand as an antagonist was derived from the full concentration-effect curves. We determined the desensitization potency of each ligand by pre-treating cells with the test compound for 10 minutes before 100 μM (−)-nicotine was applied. The potency of a ligand to desensitize the receptor after a 10 minute exposure (IC50(10′) was obtained with full concentration-effect curves using at least 8 concentrations of the ligand. | B | 5 | pIC50 | >10000 | nM | IC50 | US-9303017-B2. 2,5-disubstituted-pyridyl nicotinic ligands, and methods of use thereof (2016) |

| ChEMBL | Functional Assay: The functional properties of the ligands were determined by 86Rb+ efflux assays in cells expressing α3β4 and α4β2 nAChR subtypes. The functional activity of each ligand was measured for its agonism, antagonism and desensitization ability. Agonist activity for each of the ligands was tested at eight different concentrations. The responses were compared to that stimulated by 100 μM (−)-nicotine, a near maximally effective concentration. The full concentration-effect curves generated potency (EC50) and efficacy (Emax) of each ligand. | B | 4.64 | pEC50 | 23000 | nM | EC50 | US-9303017-B2. 2,5-disubstituted-pyridyl nicotinic ligands, and methods of use thereof (2016) |

| ChEMBL | [3H]-Epibatidine Radioligand Binding Assay: Briefly, cultured cells at >80% confluence were removed from their flasks (80 cm^2) with a disposable cell scraper and placed in 10 mL of 50 mM Tris.HCl buffer (pH 7.4, 4 °C.). The cell suspension was centrifuged at 10,000×g for 5 min and the pellet was collected. The cell pellet was then homogenized in 10 mL buffer with a polytron homogenizer and centrifuged at 36,000 g for 10 min at 4 °C. The membrane pellet was resuspended in fresh buffer, and aliquots of the membrane preparation were used for binding assays. The concentration of [3H]-epibatidine used was ~500 pM for competition binding assays. Nonspecific binding was assessed in parallel incubations in the presence of 300 μM nicotine. Bound and free ligands were separated by vacuum filtration through Whatman GF/C filters treated with 0.5% polyethylenimine. The filter-retained radioactivity was measured by liquid scintillation counting. Specific binding was defined as the difference between total binding and nonspecific binding. Data from competition binding assays were analyzed using Prism 5 (GraphPad Software, San Diego, Calif.). The Kd values for [3H]-epibatidine used for calculating Ki values of nAChR subtypes were 0.02 nM for α2β2, 0.08 nM for α2β4, 0.03 nM for α3β2, 0.3 nM for α3β4, 0.04 nM for α4β2, 0.09 nM for α4β4, 1.8 nM for α7 and 0.05 for rat forebrain. | B | 8 | pKi | 10 | nM | Ki | US-9303017-B2. 2,5-disubstituted-pyridyl nicotinic ligands, and methods of use thereof (2016) |

| ChEMBL | Functional Assay: IC50(10′): The functional properties of the ligands were determined by 86Rb+ efflux assays in cells expressing α3β4 and α4β2 nAChR subtypes. The functional activity of each ligand was measured for its agonism, antagonism and desensitization ability. Agonist activity for each of the ligands was tested at eight different concentrations. The responses were compared to that stimulated by 100 μM (−)-nicotine, a near maximally effective concentration. The potency (IC50(0′)) of each ligand as an antagonist was derived from the full concentration-effect curves. We determined the desensitization potency of each ligand by pre-treating cells with the test compound for 10 minutes before 100 μM (−)-nicotine was applied. The potency of a ligand to desensitize the receptor after a 10 minute exposure (IC50(10′) was obtained with full concentration-effect curves using at least 8 concentrations of the ligand. | B | 6.43 | pIC50 | 370 | nM | IC50 | US-9303017-B2. 2,5-disubstituted-pyridyl nicotinic ligands, and methods of use thereof (2016) |

| ChEMBL | [3H]-Epibatidine Radioligand Binding Assay: Briefly, cultured cells at >80% confluence were removed from their flasks (80 cm^2) with a disposable cell scraper and placed in 10 mL of 50 mM Tris.HCl buffer (pH 7.4, 4 °C.). The cell suspension was centrifuged at 10,000×g for 5 min and the pellet was collected. The cell pellet was then homogenized in 10 mL buffer with a polytron homogenizer and centrifuged at 36,000 g for 10 min at 4 °C. The membrane pellet was resuspended in fresh buffer, and aliquots of the membrane preparation were used for binding assays. The concentration of [3H]-epibatidine used was ~500 pM for competition binding assays. Nonspecific binding was assessed in parallel incubations in the presence of 300 μM nicotine. Bound and free ligands were separated by vacuum filtration through Whatman GF/C filters treated with 0.5% polyethylenimine. The filter-retained radioactivity was measured by liquid scintillation counting. Specific binding was defined as the difference between total binding and nonspecific binding. Data from competition binding assays were analyzed using Prism 5 (GraphPad Software, San Diego, Calif.). The Kd values for [3H]-epibatidine used for calculating Ki values of nAChR subtypes were 0.02 nM for α2β2, 0.08 nM for α2β4, 0.03 nM for α3β2, 0.3 nM for α3β4, 0.04 nM for α4β2, 0.09 nM for α4β4, 1.8 nM for α7 and 0.05 for rat forebrain. | B | 7.4 | pKi | 40 | nM | Ki | US-9303017-B2. 2,5-disubstituted-pyridyl nicotinic ligands, and methods of use thereof (2016) |

| ChEMBL | [3H]-Epibatidine Radioligand Binding Assay: Briefly, cultured cells at >80% confluence were removed from their flasks (80 cm^2) with a disposable cell scraper and placed in 10 mL of 50 mM Tris.HCl buffer (pH 7.4, 4 °C.). The cell suspension was centrifuged at 10,000×g for 5 min and the pellet was collected. The cell pellet was then homogenized in 10 mL buffer with a polytron homogenizer and centrifuged at 36,000 g for 10 min at 4 °C. The membrane pellet was resuspended in fresh buffer, and aliquots of the membrane preparation were used for binding assays. The concentration of [3H]-epibatidine used was ~500 pM for competition binding assays. Nonspecific binding was assessed in parallel incubations in the presence of 300 μM nicotine. Bound and free ligands were separated by vacuum filtration through Whatman GF/C filters treated with 0.5% polyethylenimine. The filter-retained radioactivity was measured by liquid scintillation counting. Specific binding was defined as the difference between total binding and nonspecific binding. Data from competition binding assays were analyzed using Prism 5 (GraphPad Software, San Diego, Calif.). The Kd values for [3H]-epibatidine used for calculating Ki values of nAChR subtypes were 0.02 nM for α2β2, 0.08 nM for α2β4, 0.03 nM for α3β2, 0.3 nM for α3β4, 0.04 nM for α4β2, 0.09 nM for α4β4, 1.8 nM for α7 and 0.05 for rat forebrain. | B | 6.29 | pKi | 517 | nM | Ki | US-9303017-B2. 2,5-disubstituted-pyridyl nicotinic ligands, and methods of use thereof (2016) |
