InChIKey: XSMDMCQWMREAHT-UHFFFAOYSA-N
Target: Orexin receptor type 2 (SINGLE PROTEIN), Homo sapiens
UniProt: O43614
Assay: Human Orexin 2 Receptor Ca2+ Mobilization Assay: PFSK-1 cells endogenously expressing the human orexin 2 receptor were grown to confluency in RPMI1640 (Hyclone, cat #30027.02), 10% FBS, 1× pen-strep. Cells were seeded on to 384-well Packard viewplates at a density of 5,000 cells/well and incubated overnight at 37° C., 5% CO2. The cells were dye-loaded with BD Calcium Assay kit (BD, cat #640178) in HBSS (Gibco, cat #14025-092) with 2.5 mM probenecid and incubated at 37° C., 5% CO2 for 45 min. Cells were pre-incubated with compounds (diluted in DMEM/F-12) for 15-30 minutes before agonist (orexin B, 100 nM) stimulation. Ligand-induced Ca2+ release was measured using a Fluorometric Imaging Plate Reader (FLIPR, Molecular Devices, Sunnyvale, Calif.). Functional responses were measured as peak fluorescence intensity minus basal. The concentration of agonist that produced a half-maximal response is represented by the EC50 value. Antagonistic potency values were converted to apparent pKB values using a modified Cheng-Prusoff correction. Apparent pKB=−log IC50/1+[conc agonist/EC50].

Competition binding experiments in 96 well polypropylene plates were performed using [3H]-EMPA (Moraveck Corporation, specific activity=29.6 Ci/mmol), diluted to a 5 nM concentration in PBS (2 nM final concentration). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentration (from 0.1 nM to 10 μM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 μM almorexant. The total volume of each reaction is 200 μL (20 μL of diluted compounds, 80 μL of [3H]-EMPA diluted in PBS and 100 μL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

After centrifugation (2K×G, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at −80° C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec just prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-EMPA (Moraveck Corporation, specific activity=29.6 Ci/mmol), diluted to a 5 nM concentration in PBS (2 nM final concentration). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentration (from 0.1 nM to 10 μM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 μM almorexant. The total volume of each reaction is 200 μL (20 μL of diluted compounds, 80 μL of [3H]-EMPA diluted in PBS and 100 μL of the cell suspension).

Assay: Inhibition Assay: The ability of the nuclear factor-kappa B (NF-kB)-inducing kinase (NIK) to catalyze the hydrolysis of adenosine-5'-triphosphate (ATP) was monitored using the Transcreener ADP (adenosine-5'-diphosphate) assay (BellBrook Labs). Purified NIK (0.2-1 nM) derived from a baculovirus-infected insect cell expression system was incubated with test compounds for 1-3.5 hours in 50 mM 2-[4-(2-hydroxyethyl)piperazin-1-yl]ethanesulfonic acid buffer (pH 7.2) containing 10 mM MgCl.sub.2, 2 mM dithiothreitol, 10 uM ATP, 0.01% Triton X-100, 0.1% gamma-globulins from bovine blood, 1% dimethylsulfoxide (DMSO), 12 ug/mL ADP antibody and 4 nM ADP-AlexaFluor.RTM. 633 tracer. Reactions were quenched by the addition of 20 mM 2,2',2'',2'''-(ethane-1,2-diyldinitrilo)tetraacetic acid and 0.01% Brij 35. The tracer bound to the antibody was displaced by the ADP generated during the NIK reaction, which causes a decrease in fluorescence polarization that was measured by laser excitation.

InChIKey: WFYXGWWALYXGKE-UHFFFAOYSA-N
Target: cGMP-dependent 3',5'-cyclic phosphodiesterase (SINGLE PROTEIN), Homo sapiens
UniProt: O00408
Assay: Fluorescence Polarization Assay: The inhibition of PDE 2A or 10 enzyme activity was assessed using IMAP-Phosphodiesterase-cAMP fluorescence labeled substrate (Molecular Devices, Order No. R7506), IMAP TR-FRET screening express (Molecular Devices, Order No. R8160, the TR-FRET component will not be used) and PDE 2A or PDE10 protein expressed upon baculovirus infection in SF9 cells. The cells were incubated after infection for ~3 days and protein production was confirmed by Western Blot. The cells were collected by centrifugation and the pellet frozen in liquid nitrogen before it was resuspended in PBS containing 1% Triton X-100 and protease inhibitors. After 45 min incubation on ice, the cell debris was removed by centrifugation (13.000 rpm, 30 min). Since SF 9 cells do not express cAMP hydrolyzing enzymes to a high extent, no further purification of the protein was needed.All reactions were performed in 384 well plates, Perkin Elmer black optiplates and IMAP reaction buffer with 0.1% Tween20 (kit component).
Measurement: IC50 = 125 nM (pChEMBL 6.900000095367432)
