UniProt: P56719
Assay: FLIPR Ca2+ Flux Assay: Chinese hamster ovary (CHO) cells expressing the rat orexin-1 receptor or the human orexin-2 receptor, are grown in Iscove's modified DMEM containing 2 mM L-glutamine, 0.5 g/ml G418, 1% hypoxanthine-thymidine supplement, 100 U/ml penicillin, 100 ug/ml streptomycin and 10% heat-inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into Becton-Dickinson black 384-well clear bottom sterile plates coated with poly-D-lysine. All reagents were from GIBCO-Invitrogen Corp. The seeded plates are incubated overnight at 37° C. and 5% CO2. Ala-6,12 human orexin-A as the agonist is prepared as a 1 mM stock solution in 1% bovine serum albumin (BSA) and diluted in assay buffer (HBSS containing 20 mM HEPES, 0.1% BSA and 2.5 mM probenecid, pH7.4) for use in the assay at a final concentration of 70 pM. Test compounds are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates, first in DMSO, then assay buffer. On the day of the assay, cells are washed 3 times with 100 ul assay buffer and then incubated for 60 min (37° C., 5% CO2) in 60 ul assay buffer containing 1 uM Fluo-4AM ester, 0.02% pluronic acid, and 1% BSA. The dye loading solution is then aspirated and cells are washed 3 times with 100 ul assay buffer. 30 ul of that same buffer is left in each well. Within the Fluorescent Imaging Plate Reader (FLIPR, Molecular Devices), test compounds are added to the plate in a volume of 25 ul, incubated for 5 min and finally 25 ul of agonist is added. Fluorescence is measured for each well at 1 second intervals for 5 minutes and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 70 pM Ala-6,12 orexin-A with buffer in place of antagonist.

Assay: FLIPR Ca2+ Flux Assay: Chinese hamster ovary (CHO) cells expressing the rat orexin-1 receptor or the human orexin-2 receptor, are grown in Iscove's modified DMEM containing 2 mM L-glutamine, 0.5 g/ml G418, 1% hypoxanthine-thymidine supplement, 100 U/ml penicillin, 100 ug/ml streptomycin and 10% heat-inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into Becton-Dickinson black 384-well clear bottom sterile plates coated with poly-D-lysine. All reagents were from GIBCO-Invitrogen Corp. The seeded plates are incubated overnight at 37° C. and 5% CO2. Ala-6,12 human orexin-A as the agonist is prepared as a 1 mM stock solution in 1% bovine serum albumin (BSA) and diluted in assay buffer (HBSS containing 20 mM HEPES, 0.1% BSA and 2.5 mM probenecid, pH7.4) for use in the assay at a final concentration of 70 pM. Test compounds are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates, first in DMSO, then assay buffer. On the day of the assay, cells are washed 3 times with 100 ul assay buffer and then incubated for 60 min (37° C., 5% CO2) in 60 ul assay buffer containing 1 uM Fluo-4AM ester, 0.02% pluronic acid, and 1% BSA. The dye loading solution is then aspirated and cells are washed 3 times with 100 ul assay buffer. 30 ul of that same buffer is left in each well. Within the Fluorescent Imaging Plate Reader (FLIPR, Molecular Devices), test compounds are added to the plate in a volume of 25 ul, incubated for 5 min and finally 25 ul of agonist is added. Fluorescence is measured for each well at 1 second intervals for 5 minutes and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 70 pM Ala-6,12 orexin-A with buffer in place of antagonist.

Assay: Radioligand Binding Assay: Membranes for radioligand binding experiments are prepared from fresh or frozen cells as described in Klotz et al., Naunyn-Schmiedeberg's Arch. Pharmacol, 357:1-9 (1998). The cell suspension is then homogenized in ice-cold hypotonic buffer (5 mM Tris/HCl, 2 mM EDTA, pH 7.4) and the homogenate is spun for 10 minutes (4° C.) at 1,000 g. The membranes are then sedimented from the supernatant for 30 minutes at 100,000 g and resuspended in 50 mM Tris/HCl buffer pH 7.4 (for A3 adenosine receptors: 50 mM Tris/HCl, 10 mM MgCl2, 1 mM EDTA, pH 8.25), frozen in liquid nitrogen at a protein concentration of 1-3 mg/mL and stored at −80° C. Dissociation constants of unlabeled compounds (Ki-values) are determined in competition experiments in 96-well microplates using the A1 selective agonist 2-chloro-N6-[3H]cyclopentyladenosine ([3H]CCPA, 1 nM) for the characterization of A1 receptor binding. Nonspecific binding is determined in the presence of 100 Î¼M R-PM and 1 mM theophylline, respectively.

Compound (SMILES): CC(=O)N1CCC(C(=O)N2CC[C@@H](N(C)C(=O)c3ccc(Cl)cc3)[C@H](c3ccc(Cl)c(Cl)c3)C2)CC1
InChIKey: RPTJPWCOBZLMMD-WIOPSUGQSA-N
Target: Substance-P receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P25103
Assay: Human NK1 Receptor Binding Assay: IM-9 cells (2×10^5 cells/mL) were cultured for 3 days after inoculation, and centrifuged at 500×g for 10 min to give cell pellets. The obtained pellets were washed with PBS (Phosphate-Buffered saline) (GIBCO), disrupted in buffer A (50 mM Tris-hydrochloric acid buffer (Tris-HCl) (pH 7.4) containing 120 mM sodium chloride, 5 mM potassium chloride, 2 μg/mL chymostatin, 40 μg/mL bacitracin, 40 μg/mL APMSF (p-amidinophenylmethanesulfonyl fluoride hydrochloride) and 1 mM ethylenediaminetetraacetic acid (EDTA)) using a Polytron homogenizer (Kinematika, Germany), and centrifuged at 100,000×g for 40 min. The precipitation fraction was suspended in buffer B (50 mM Tris-HCl (pH 7.4), 0.02% bovine serum albumin, 2 μg/mL chymostatin, 40 μg/mL bacitracin, 40 μg/mL APMSF, 3 mM manganese dichloride (MnCl2)) and cryopreserved (−80° C.) as a receptor reference standard. Buffer B (50 μL) was added to a 96-well microassay plate (Corning Incorporated). The membrane reference standard suspended in buffer B at 250 μg/mL was added by 50 μL. A measurement buffer containing 2% dimethyl sulfoxide was added by 50 μL to examine the total binding, 4 μM non-labeled SP diluted with a measurement buffer containing 2% dimethyl sulfoxide was added by 50 μL to examine the non-specific binding, and a test compound diluted with a measurement buffer (containing 2% dimethyl sulfoxide) was added by 50 μL to examine the binding inhibitory activity of the test compound. Furthermore, 400 μM 125I-Bolton-Hunter-SP (BH-SP) solution was added to each well by 50 μL. After reaction at room temperature for 30 min, the reaction was quenched using a cell harvester (PerkinElmer) by rapid filtration on a GF/C filter plate (PerkinElmer), and the cells were washed 10 times with 250 μL of a 50 mM Tris-hydrochloric acid buffer (pH 7.4) containing 0.02% bovine serum albumin. The GF/C filter plate was dried, MicroScinti-0 (PerkinElmer) was added by 20 μL, and the radioactivity was measured on a TopCount (PerkinElmer). The GF/C filter plate was immersed in 0.3% polyethyleneimine for one day before use.
