Assay: ThermoFluor® Assay: ThermoFluor® experiments were carried out using instruments owned by Janssen Research and Discovery, L.L.C. through its acquisition of 3-Dimensional Pharmaceuticals, Inc. 1,8-ANS (Invitrogen) was used as a fluorescent dye. Protein and compound solutions are dispensed into black 384-well polypropylene PCR microplates (Abgene) and overlayed with silicone oil (1 μL, Fluka, type DC 200) to prevent evaporation. Bar-coded assay plates are robotically loaded onto a thermostatically controlled PCR-type thermal block and then heated at a typical ramp-rate of 1 °C./min for all experiments. Fluorescence was measured by continuous illumination with UV light (Hamamatsu LC6) supplied via fiber optic and filtered through a band-pass filter (380-400 nm; >60D cutoff). Fluorescence emission of the entire 384-well plate was detected by measuring light intensity using a CCD camera (Sensys, Roper Scientific) filtered to detect 500±25 nm, resulting in simultaneous and independent readings of all 384 wells. Images were collected at each temperature, and the sum of the pixel intensity in a given area of the assay plate was recorded versus temperature. Reference wells contained RORγt without compounds, and the assay conditions were as follows: 0.065 mg/mL RORγt, 60 μM 1,8-ANS, 100 mM Hepes, pH 7.0, 10 mM NaCl, 2.5 mM GSH, 0.002% Tween-20. Project compounds were arranged in a pre-dosed mother plate (Greiner Bio-one) wherein compounds are serially diluted in 100% DMSO by 1:2 from a high concentration of 10 mM over 12 columns within a series (column 12 is a reference well containing DMSO, no compound). The compounds were robotically dispensed directly into assay plates (1x=46 mL) using a Hummingbird capillary liquid handling instrument (Digilab). Following compound dispense, protein and dye in buffer was added to achieve the final assay volume of 3 μL, followed by 1 μL of silicone oil.

Assay: Muscarinic Receptor Binding Assay: The study of binding to human muscarinic M1, M2, M3, M4 and M5 receptors was performed using commercial membranes (Perkin Elmer) prepared from CHO-K1 cells. Radioligand binding experiments were conducted in 96 polypropylene well plates in a total volume of 200 μl. All reagents were dissolved in assay binding buffer (PBS with calcium and magnesium, SIGMA), except compounds that were dissolved in DMSO 100%. Non-specific binding (NSB) was measured in the presence of 1 μM atropine. [3H]-NMS was used as the radioligand at a concentration of 1 nM for M2, M3 and M5 and 0.3 nM for M1 and M4. [3H]-NMS and antagonists were incubated with membranes that express human muscarinic receptors M1, M2, M3, M4 and M5 at concentrations of 8.1, 10, 4.9, 4.5 and 4.9 μg/well, respectively. After an incubation period of two hours with gentle shaking, 150 μl of the reaction mix were transferred to 96 GF/C filter plates (Millipore), previously treated with wash buffer (Tris 50 mM; NaCl 100 mM; pH: 7.4), containing 0.05% PEI (Sigma) during one hour. Bound and free [3H]-NMS were separated by rapid vacuum filtration in a manifold from Millipore and washed four times with ice cold wash buffer. After drying 30 min, 30 μl of OPTIPHASE Supermix were added to each well and radioactivity quantified using a Microbeta microplate scintillation counter.

UniProt: Q9NYK1
Assay: Pharmacological Assay: For TLR8 and TLR7 activity testing, HEK-Blue human TLR8 or TLR7 cells (Invivogen, San Diego, Calif., USA) are used, respectively. These cells are designed for studying the stimulation of human TLR8 or TLR7 by monitoring the activation of NF-κB. A SEAP (secreted embryonic alkaline phosphatase) reporter gene is placed under the control of the IFN-b minimal promoter fused to five NF-κB and AP-1-binding sites. Therefore the reporter expression is regulated by the NF-κB promoter upon stimulation of human TLR8 or TLR7 for 20 hours. The cell culture supernatant SEAP reporter activity was determined using Quanti Blue kit (Invivogen, San Diego, Ca, USA) at a wavelength of 640 nm, a detection medium that turns purple/blue in the presence of alkaline phosphatase.

Assay: ADP Hunter Plus Assay: The kinase activity was measured by using the commercial ADP Hunter Plus assay available from DiscoveRx (#90-0083), which is a homogeneous assay to measure the accumulation of ADP, a universal product of kinase activity. The enzyme, DNA-PK was purchased from Promega (#V5811). The assay was done following the manufacturer recommendations with slight modifications: Mainly the kinase buffer was replace by 15 mM HEPES, pH 7.5, 10 mM MgCl2, 20 mM NaCl, 1 mM EGTA, 0.1 mg/mL BGG, 0.02% Tween 20. The DNA-PK was assayed in a titration experiment to determine the optimal protein concentration for the inhibition assay. To calculate the 1050 of the Compounds, serial 1:3 dilutions of the compounds were added to the enzyme at a fixed concentration (2 U/uL). The enzyme was preincubated with the inhibitor and 200 uM DNA substrate and then ATP was added to a final 75 uM concentration. Reaction was carried out for 1 hour at 37° C. Reagent A and B were sequentially added to the wells and plates were incubated for 30 min at RT. Fluorescence counts were read in a EnVision instrument (Perkin Elmer) with the recommended settings (550 and 590 nm as excitation and emission wavelengths, respectively). Values were normalized against the control activity included for each enzyme (i.e., 100% DNA_PK kinase activity, without compound). These values were plotted against the inhibitor concentration and were fit to a sigmoid dose-response curve by using the model sigmoidal Four-Parameter Logistc implement for Activity base - software.

Assay: Electrophysiology Assay: After establishing the whole-cell configuration in voltage clamp mode, voltage protocols were run to establish the 1) test potential, 2) holding potential, and 3) the conditioning potential for each cell. After establishing the whole-cell configuration in voltage clamp mode, a standard I-V protocol was run to determine the potential at which the maximal current (Imax) is elicited. This potential was the test potential (Vt). To determine a conditioning potential at which 100% of channels were in the inactivated state, a standard steady-state inactivation (SSIN) protocol was run using a series of fifteen 100 ms-long depolarizing prepulses, incrementing in 10 mV steps, immediately followed by a 5 ms testing pulse, Vt, to Vmax. This protocol also permitted determination of the holding potential at which all channels are in the resting state.

Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 384-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction. Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer].

Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction.Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 10-point dosing curve having a high dose of 1 uM. A reference compound was included on each assay plate in order to validate that plate.

Assay: Intracellular Calcium 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 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. Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 μL/well, incubated for 120 min and finally 10 μL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist.

Assay: G402-Based Assay: Herein we identified the use of the G-402 cell line as a host cell to ectopically express (transiently or stably) enzymes of the CYP11 family. Specifically we developed stable G-402 cells expressing ectopically human CYP11B1, human CYP11B2, human CYP11A1, cynmolgus CYP11B1 or cynomolgus CYP11B2 enzyme activity. Importantly the identified cell line G-402 expresses co-factors (adrenodoxin and adrenodoxin reductase) important for the activity of the CYP11 family and no relevant enzyme activity of the CYP11 family (in comparison to H295R cells) was detected in these cells. Therefore the G-402 cell line is uniquely suited as a host cell for the ectopic expression of enzymes from the CYP11 family.Cellular enzyme assays were performed in DMEM/F12 medium containing 2.5% charcoal treated FCS and appropriate concentration of substrate (0.3-10 uM 11-Deoxycorticosterone, 11-Deoxycortisol or Corticosterone). For assaying enzymatic activity, cells were plated onto 96 well plates and incubated for 16 h. An aliquot of the supernatant is then transferred and analyzed for the concentration of the expected product (Aldosterone for CYP11B2; Cortisol for CYP11B1). The concentrations of these steroids can be determined using HTRF assays from CisBio analyzing either Aldosterone or Cortisol.

Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 10-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The final buffer conditions were as follows: 60 mM Hepes, pH 7.0, 0.05% BSA, 2 mM DTT. Incubations were carried out at RT (22° C.) for 2 h for Pim-1, 1 hour and 30 min for Pim-3, and 45 min for Pim-2. The reaction was stopped by the addition of 3 mM EDTA, and fluorescence was measured by an HTRF® Rubystar microplate reader.

Assay: Pharmacological Assay: For TLR8 and TLR7 activity testing, HEK-Blue human TLR8 or TLR7 cells (Invivogen, San Diego, Calif., USA) are used, respectively. These cells are designed for studying the stimulation of human TLR8 or TLR7 by monitoring the activation of NF-κB. A SEAP (secreted embryonic alkaline phosphatase) reporter gene is placed under the control of the IFN-b minimal promoter fused to five NF-κB and AP-1-binding sites. Therefore the reporter expression is regulated by the NF-κB promoter upon stimulation of human TLR8 or TLR7 for 20 hours. The cell culture supernatant SEAP reporter activity was determined using Quanti Blue kit (Invivogen, San Diego, Ca, USA) at a wavelength of 640 nm, a detection medium that turns purple/blue in the presence of alkaline phosphatase.

Assay: Functional Assay: HEK293 cells were transfected with human TRPV1 cloned in pcDNA3.1zeo(+) using the Effectene non-liposomal lipid based transfection kit (Qiagen) (hTRPV1/HEK293). hTRPV1/HEK293 cells were routinely grown as monolayers under selection in zeocin (200 μg/mL; Invitrogen) in Dulbecco's Modified Eagle Medium (DMEM, Gibco BRL) supplemented with 10% fetal bovine serum, and penicillin/streptomycin (50 units/mL) in 5% CO2 at 37° C. Cells were passaged frequently, every 3-5 days, to avoid overgrowth, depletion of essential medium components, or acidic medium exposure. Cells were passaged using a brief wash in 0.05% trypsin with 1 mM EDTA, followed by dissociation in divalent-free phosphate-buffered saline (Hyclone #SH30028.02). Dissociated cells were seeded onto poly-D-lysine coated black-walled 96-well plates (Biocoat; Becton Dickinson #354640) at about 40,000 cells per well and grown for approximately 1 day in culture medium to near confluency. The assay buffer was composed of 130 mM NaCl, 2 mM KCl, 2 mM MgCl2, 10 mM HEPES, 5 mM glucose, and either 2 mM or 20 μM CaCl2. On the day of the experiment, the culture medium was replaced with 2 mM calcium assay buffer using an automated plate washer (ELx405; Biotek, VT). The cells were incubated in 100 μL/well Fluo-3/AM (2 μM; TEFLabs #0116) with Pluronic F127 (100 μg/mL; Sigma #P2443) for 1 h at rt in the dark. After loading the cells, the dye solution was replaced with 50 μL/well of 20 μM calcium assay buffer using the ELx405 plate washer. Test compounds (50 μL/well) were added to the plate and incubated for 30 min. Intracellular Ca2+ levels were subsequently assayed using a Fluorometric Imaging Plate Reader (FLIPR™ instrument, Molecular Devices, CA) to simultaneously monitor Fluo-3 fluorescence in all wells (λexcitation=488 nm, λemission=540 nm) during challenge with agonist (capsaicin). The IC50 values were determined. Cells were challenged with 150 nM capsaicin and the fluorescence counts were captured following agonist addition at a sampling rate of 0.33 Hz. The contents of the wells were mixed 3 times (40 μL mix volume) immediately after the additions were made. Concentration dependence of block was determined by exposing each well of cells in duplicate rows of a 96 well plate to a serial dilution of test compound. The concentration series usually started at 10 Î¼M with a three-fold serial decrement in concentration. The magnitude of the capsaicin response was determined by measuring the change in fluo3 fluorescence before and 100 seconds after the addition of the agonist.

Target: Tyrosine-protein kinase JAK2 (SINGLE PROTEIN), Homo sapiens
UniProt: O60674
Assay: Enzyme Assay: JAK1, JAK2, JAK3 and Tyk2 were purchased from Carna Biosciences, Inc. As the substrate, LANCE Ultra ULight-JAK1 Peptide (manufactured by PerkinElmer Co., Ltd. (PE)) was used. Dilute solutions of compounds and enzymes in assay buffer (50 mM HEPES pH7.5, 1 mM EGTA, 1 mM MgCl2, 2 mM DTT, 0.01% Tween20) were dispensed into wells of a 384-well black plate. After 5 minutes of preincubation, dilute solutions of the substrate and ATP (adenosine triphosphate) were added at a final concentration of 100 μM, and the plate was incubated at room temperature for 2 hours. After addition of a termination reagent containing EDTA (ethylenediamine tetraacetic acid) at a final concentration of 10 mM, LANCE Eu-W1024 Anti-phosphotyrosine (PT66) (manufactured by PE) was added, and after 1 hour of incubation, the fluorescences were measured with ARVO-HTS.
