Target: Interleukin-1 receptor-associated kinase 4 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NWZ3
Assay: Kinase Assay: The kinase activity of IRAK-4 is determined by its ability to catalyze the phosphorylation of a fluorescent polypeptide substrate. The extent of phosphorylation is measured using the IMAP technology (Molecular Devices) where the phosphorylated fluorescent substrate binds to the large M(III)-based nanoparticles which reduces the rotational speed of the substrate and thus increases its fluorescent polarization (FP). 20 μl reaction mixture contains 10 mM TriHCl, pH 7.2, 0.5 nM GST tagged IRAK-4 (SignalChem), 100 nM fluorescent peptide substrate (RP7030, Molecular Devices), 100 μM ATP, 1 mM DTT, 1 mM MgCl2, and 0.01% Tween 20. The reaction is initiated by the addition of ATP. After incubation for 30 minutes at 25° C., 60 μl of Progressive IMAP Reagent (Molecular Devices) is added to stop the reaction. Change in RP7030's FP is determined by a FP reader (Analyst HT, LH, BioSystems).

Assay: In Vitro ATP-33P Casein Assay: "U"-bottomed Falcon plates are prepared by placing 5 uL of solutions of the compounds according to the invention at concentrations of 10, 1, 0.1, 0.01 or 0.001 uM in different wells. The solutions of the compounds according to the invention at these various concentrations are prepared by diluting in a test buffer (Tris 50 mM pH 7.5, MgCl2 10 M, DTT 2 mM and EGTA 1 mM) a stock solution in DMSO at a concentration of 10 mM. Next, 5 uL of dephosphorylated casein are added to a final concentration of 0.2 ug/uL, 20 uL of CK1 epsilon to a final concentration of 3 ng/uL, and 20 uL of ATP-33P to a final concentration of 0.02 uCi/uL mixed with cold ATP (10 uM final approximately 2x106 CPM per well). The final total test volume per well is equal to 50 uL. The "U"-bottomed Falcon test plate mentioned above is vortexed, and then incubated at room temperature for 2 hours. After 2 hours the reaction is stopped by adding an ice-cold solution of 65 uL of cold ATP (2 mM) prepared in test buffer. 100 uL of the reaction mixture are then transferred from the "U"-bottomed Falcon plate into Millipore MAPH filter plates, preimpregnated with 25 uL of ice-cold 100% TCA. The Millipore MAPH filter plates are agitated gently and are left to stand at room temperature for at least 30 minutes to precipitate the proteins. After 30 minutes, the filter plates are sequentially washed and filtered with 2x150 uL of 20% TCA, 2x150 uL of 10% TCA and 2x150 uL of 5% TCA (6 washes in total per plate/900 uL per well). The plates are left to dry overnight at room temperature. Next, 40 uL of Microscint-20 Packard scintillation liquid are added per well and the plates are closed in a leaktight manner. The radiation emitted by each well is then measured for 2 minutes in a TopCount NXT Packard scintillation counter, in which the values of CPM/well are measured.

Assay: ThermoFluor® Assay: 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; >6 OD 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 (1×=46 nL) 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: Functional Assay: The functional activity of compounds of the formula (I) was determined by measuring changes in intracellular calcium concentration using a Ca2+-sensitive fluorescent dye. The changes in fluorescent signal were monitored by a fluorescence plate reader, either a FLIPR (Molecular Devices) or FDSS (Hamamatsu). Increases in intracellular Ca2+ concentration were readily detected upon activation with icilin.At 24 hrs prior to assay, HEK293 cells stably expressing canine TRPM8 were seeded in culture medium in black wall, clear-base poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) and grown overnight in 5% CO2 at 37° C. On assay day, growth media was removed and cells were loaded with Calcium 3 Dye (Molecular Devices) for 35 min at 37° C., under 5% CO2 and then for 25 min at room temperature and atmosphere. Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR or FDSS. Cells were challenged with a compound of the Formula (I) (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to all wells to achieve a final concentration that produces approximately an 80% maximal response. EC50 or IC50 values for compounds of the present invention were determined from eight-point dose-response studies.

Assay: Scintillation Proximity Assay (SPA): The binding of potential ligands to RORγ is measured by competition with [3H] 25-hydroxycholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA) binding assay. The ligand binding domain of human RORγ (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15 ug/well RORγ (A262-S507) is incubated with test compound at varying concentrations in 3-fold serial dilution, with final concentrations ranging from 16.6 uM to 0.28 nM for 10 min at room temperature in PBS buffer (Invitrogen #14190-144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% Glycerol (Sigma Cat#G5516). 10 nM of [3H] 25-hydroxycholesterol is then added, and the reaction is incubated for 10 min. 10 mg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat #RPNQ0095) are added, and the mixture is incubated for 60 min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC50 values were determined. The IC50 value is defined as the concentration of test compound needed to reduce [3H] 25-hydroxycholesterol specific binding by 50% and is calculated using the four parameter logistic equation to fit the normalized data.

Assay: VEGFR2 Kinase Assay: Biochemical KDR kinase assays were performed in 96 well microtiter plates that were coated overnight with 75 μg/well of poly-Glu-Tyr (4:1) in 10 mM Phosphate Buffered Saline (PBS), pH 7.4. The coated plates were washed with 2 mls per well PBS+0.05% Tween-20 (PBS-T), blocked by incubation with PBS containing 1% BSA, then washed with 2 mls per well PBS-T prior to starting the reaction. Reactions were carried out in 100 μL reaction volumes containing 2.7 μM ATP in kinase buffer (50 mM Hepes buffer pH 7.4, 20 mM MgCl2, 0.1 mM MnCl2 and 0.2 mM Na3VO4). Test compounds were reconstituted in 100% DMSO and added to the reaction to give a final DMSO concentration of 5%. Reactions were initiated by the addition 20 μl per well of kinase buffer containing 200-300 ng purified cytoplasmic domain KDR protein (BPS Bioscience, San Diego, Calif.). Following a 15 minute incubation at 30° C., the reactions were washed 2 mls per well PBS-T. 100 μl of a monoclonal anti-phosphotyrosine antibody-peroxidase conjugate diluted 1:10,000 in PBS-T was added to the wells for 30 minutes. Following a 2 mis per well wash with PBS-Tween-20, 100 μl of O-Phenylenediamine Dihydrochloride in phosphate-citrate buffer, containing urea hydrogen peroxide, was added to the wells for 7-10 minutes as a colorimetric substrate for the peroxidase. The reaction was terminated by the addition of 100 μl of 2.5N H2SO4 to each well and read using a microplate ELISA reader set at 492 nm.

Assay: Functional Assay: The functional activity of compounds of the formula (I) was determined by measuring changes in intracellular calcium concentration using a Ca2+-sensitive fluorescent dye. The changes in fluorescent signal were monitored by a fluorescence plate reader, either a FLIPR (Molecular Devices) or FDSS (Hamamatsu). Increases in intracellular Ca2+ concentration were readily detected upon activation with icilin.At 24 hrs prior to assay, HEK293 cells stably expressing canine TRPM8 were seeded in culture medium in black wall, clear-base poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) and grown overnight in 5% CO2 at 37° C. On assay day, growth media was removed and cells were loaded with Calcium 3 Dye (Molecular Devices) for 35 min at 37° C., under 5% CO2 and then for 25 min at room temperature and atmosphere. Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR or FDSS. Cells were challenged with a compound of the Formula (I) (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to all wells to achieve a final concentration that produces approximately an 80% maximal response. EC50 or IC50 values for compounds of the present invention were determined from eight-point dose-response studies.
