| ChEMBL | Inhibition Assay: Chinese hamster ovary (CHO) cells expressing the human orexin-1 receptor and the human orexin-2 receptor, respectively, are grown in culture medium (Ham F-12 with L-Glutamine) containing 300 μg/ml G418, 100 U/ml penicillin, 100 μg/ml streptomycin and 10% heat inactivated fetal calf serum (FCS). The cells are seeded at 20,000 cells/well into 384-well black clear bottom sterile plates (Greiner). The seeded plates are incubated overnight at 37° C. in 5% CO2.Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH: water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/l and 20 mM HEPES for use in the assay at a final concentration of 3 nM.Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/l and 20 mM HEPES. On the day of the assay, 50 μl of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/l, 5 mM probenecid (Sigma) and 3 M of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at RT for 30 min before measurement. | B | 8.7 | pIC50 | 2 | nM | IC50 | US-9732075-B2.

| ChEMBL | In Vitro Assay: Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH: water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/l and 20 mM HEPES for use in the assay at a final concentration of 3 nM.Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/l and 20 mM HEPES. On the day of the assay, 50 μl of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/l, 5 mM probenecid (Sigma) and 3 μM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at RT for 30 min before measurement. | B | 8.7 | pIC50 | 2 | nM | IC50 | US-9914721-B2.
