Assay: VEGFR2 Kinase Assay: Biochemical KDR kinase assays were performed in 96 well microtiter plates that were coated overnight with 75 ug/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 uL reaction volumes containing 2.7 uM 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 ul 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 ul 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 mls per well wash with PBS-Tween-20, 100 ul of 0-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 ul of 2.5N H2SO4 to each well and read using a microplate ELISA reader set at 492 nm.

Assay: B-RAF (V600E) Kinase Assay: In a dilution series 10 uL/well of test substance solution are placed in a multiwell plate. The dilution series is selected so that generally a range of concentrations of 2 uM to 0.119 nM or 0.017 nM is covered. If necessary the initial concentration of 2 uM is changed to 50 uM, 10 uM or 0.4 uM or 0.2857 uM and further dilution is carried out accordingly. The final concentration of DMSO is 5%. 10 uL/well of the B-Raf (V600E)-kinase solution are pipetted in (containing 0.5 ng B-Raf (V600E)-kinase (e.g. from Upstate) in 20 mM Tris-HCl pH 7.5, 0.1 mM EDTA, 0.1 mM EGTA, 0.286 mM sodium orthovanadate, 10% glycerol, 1 mg/mL bovine serum albumin, 1 mM dithiothreitol) and the mixture is incubated for 1 h at RT under with shaking. The kinase reaction is started by the addition of 20 uL/well ATP solution [final concentration: 250 uM ATP, 30 mM Tris-HCl pH 7.5, 0.02% Brij, 0.2 mM sodium orthovanadate, 10 mM magnesium acetate, 0.1 mM EGTA, phosphatase cocktail (Sigma, #P2850, dilution recommended by the manufacturer)] and 10 uL/well MEK1 solution [containing 50 ng biotinylated MEK1 (prepared from purified MEK1 according to standard procedure, e.g. with EZ-Link Sulpho-NHS-LC-Biotin reagent, Pierce, #21335)] and carried out for 60 min at RT with constant shaking. The reaction is stopped by the addition of 12 uL/well of a 100 mM EDTA solution and incubation is continued for a further 5 min. 55 uL/well of the reaction solution are transferred into a streptavidin-coated plate (e.g. Streptawell HighBond, Roche, #11989685001) and shaken gently for 1 h at RT, in order to bind biotinylated MEK1 to the plate. After elimination of the liquid the plate is washed five times with 200 uL/well of 1Ã¿PBS and 100 uL/well solution of primary antibody plus europium-labelled secondary antibody [Anti Phospho-MEK (Ser217/221), Cell Signaling, #9121 and Eu-N1 labelled goat-anti-rabbit antibody, Perkin Elmer, #AD0105] is added, the primary antibody is diluted 1:2000 and the secondary antibody is diluted to 0.4-0.5 ug/mL in Delfia Assay Buffer (Perkin Elmer, #1244-111). After 1 h shaking at RT the solution is poured away and washed five times with 200 uL/well Delfia Wash Buffer (Perkin Elmer, #4010-0010/#1244-114). After the addition of 200 uL/well Enhancement Solution (Perkin Elmer, #4001-0010/#1244-105) the mixture is shaken for 10 min at RT and then measured in a Wallac Victor using the program "Delfia Time Resolved Fluorescence (Europium)". IC50 values are obtained from these dosage-activity curves using a software program (GraphPadPrizm).

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: 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.

Target: Tyrosine-protein kinase BTK (SINGLE PROTEIN), Homo sapiens
UniProt: Q06187
Assay: Recombinant Human BTK Inhibition Assay: The inhibition assays were performed using the generic tyrosine kinase assay kit from C is Bio (HTRF KinEASE-TK #62TK0PEB). The assay is based on the principle of fluorescence resonance energy transfer (FRET) between the Europium Cryptate labeled anti-phosphotyrosine antibody and streptavidin labeled fluorophore, XL-665. In an uninhibited kinase reaction the biotinylated peptide substrate (Tk-Biotin) gets phosphorylated at an intermediate tyrosine site which is captured by anti-phosphotyrosine antibody which eventually acts as a FRET donor. The streptavidin labeled XL-665 binds strongly to the Tk-Biotin substrate and act as a FRET acceptor. The resultant FRET signal is measured at 665 nm. A ratio of this specific fluorescence (665 nm) to the background fluorescence (620 nm), conferred by the free antibody, is directly proportional to the kinase activity. Inhibition of the kinase activity by a pharmacological intervention such as a Btk inhibitor of the present disclosure will result into decreased FRET signal.

Target: Prokineticin receptor 1 (SINGLE PROTEIN), Homo sapiens
UniProt: Q8TCW9
Assay: Biological Assay: Prokineticin receptor 1 (PKR1) antagonists may be functionally assessed by measurement of change in intracellular calcium levels induced by Gq mediated increase in inositol triphosphate (IP3) levels. The ability of a compound to block the intracellular release of calcium mediated by PK1 in RBL2H3 cells expressing human PKR1 receptors is determined as a measure of the compound's antagonist activity in vitro. Approximately 10,000 cells per assay well are seeded in normal culture medium in a 384 well plate (Corning). Twenty-four hours after seeding, the cells are loaded with a calcium sensitive fluorescent dye by replacing the culture medium with assay buffer (1xHanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH 7.4) containing 1 mM probenecid and 1x Calcium 5 Reagent (Molecular Devices). Cells are incubated at 37° C. for 1 hour to allow for dye uptake.To test for antagonist activity, test compounds at a final concentration range between 0.32 nM-10 uM (diluted in assay buffer) are added to the assay wells and allowed to incubate for 10 minutes prior to stimulation with PK1. After incubation with test compounds the assay plate is placed in a FLIPR Tetra (Molecular Devices) and PK1 (diluted in assay buffer) is added at the determined EC80 concentration (final). Ligand-dependent changes in intracellular calcium levels are determined by measuring changes in fluorescence of the dye at 525 nM following excitation at 485 nM. Readings from wells that do not contain antagonist enable percentage inhibition curves to be plotted using 4-parameter fit algorithm and IC50 values are calculated for each test compound.

Assay: Mps-1 Kinase Assay: For the assay 50 nL of a 100-fold concentrated solution of the test compound in DMSO was pipetted into a black low volume 384 well microtiter plate (Greiner Bio-One, Frickenhausen, Germany), 2 ul of a solution of Mps-1 in assay buffer [0.1 mM sodium- ortho-vanadate, 10 mM MgCl2, 2 mM DTT, 25 mM Hepes pH 7.7, 0.05% BSA, 0.001% Pluronic F-127] were added and the mixture was incubated for 15 min at 22° C. to allow pre-binding of the test compounds to Mps-1 before the start of the kinase reaction. Then the kinase reaction was started by the addition of 3 ul of a solution of 16.7 adenosine-tri-phosphate (ATP, 16.7 uM=> final conc. in the 5 ul assay volume is 10 uM) and peptide substrate (1.67 uM=> final conc. in the 5 ul assay volume is 1 uM) in assay buffer and the resulting mixture was incubated for a reaction time of 60 min at 22° C. The concentration of Mps-1 in the assay was adjusted to the activity of the enzyme lot and was chosen appropriate to have the assay in the linear range, typical enzyme concentrations were in the range of about 1 nM (final conc. in the 5 ul assay volume). The reaction was stopped by the addition of 3 ul of a solution of HTRF detection reagents (100 mM Hepes pH 7.4, 0.1% BSA, 40 mM EDTA, 140 nM Streptavidin-XLent [#61GSTXLB, Fa. Cis Biointernational, Marcoule, France], 1.5 nM anti-phospho(Ser/Thr)-Europium-antibody [#AD0180, PerkinElmer LAS, Rodgau-Jugesheim, Germany]. The resulting mixture was incubated 1 h at 22° C. to allow the binding of the phosphorylated peptide to the anti-phospho(Ser/Thr)-Europium-antibody. Subsequently the amount of phosphorylated substrate was evaluated by measurement of the resonance energy transfer from the Europium-labelled anti-phospho(Ser/Thr) antibody to the Streptavidin-XLent. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm was measured in a Viewlux TR-FRET reader (PerkinElmer LAS, Rodgau-Jugesheim, Germany).

Target: Cathepsin D (SINGLE PROTEIN), Homo sapiens
UniProt: P07339
Assay: In-Vitro Fluorescence Assay: In order to identify modulators of cathepsin D activity, a continuous enzymatic test was carried out with a synthetic peptide which carries a fluorescent group (MCA=(7-methoxycoumarin-4-yl)acetyl) which is quenched by energy transfer from a Dpn (2,4 dinitrophenyl) group on the same molecule, in Greiner 384-well nb microtitre plates. Cleavage of the peptidic substrate by cathepsin D causes an increase in the fluorescence intensity. In order to determine the efficacy of substances, the time-dependent increase in the fluorescence intensity in the presence of the substance was compared with the time-dependent increase in fluorescence in the absence of substances. The reference substance used was pepstatin A (Sigma-Aldrich). The substrate used was MCAGKPILFFRLK(Dnp)d-R-NH2 (Enzo Life Sciences, Lorrach). The enzyme employed was cathepsin D isolated from the human liver (Sigma-Aldrich) in a final concentration of 1.4 nM. The test was carried out in 100 mM sodium acetate buffer, 1.25% (v/v) of DMSO, 0.25% (w/v) of Chaps, pH 5.5. 2 ul of each substance solution with serially diluted substance concentration were added to in each case 4 ul of cathepsin D solution and incubated at room temperature for 10 min. The reaction was started by addition of 2 ul of substrate solution (final concentration 5 uM). After carrying out a starting-point fluorescence measurement (excitation wavelength 340 nm/emission wavelength 450 nm) using an Envision multilabel reader (Perkin Elmer), the reaction was incubated at room temperature for 60 min. The amount of peptide fragment cleaved off during the reaction time was subsequently measured by determination of the increase in the fluorescence intensity at 450 nm (excitation wavelength 340 nm).

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.

UniProt: P41594
Assay: Intracellular Ca2+ Mobilization Assay: A monoclonal HEK-293 cell line stably transfected with a cDNA encoding for the human mGlu5a receptor was generated; for the work with mGlu5 Positive Allosteric Modulators (PAMs), a cell line with low receptor expression levels and low constitutive receptor activity was selected to allow the differentiation of agonistic versus PAM activity. Cells were cultured according to standard protocols (Freshney, 2000) in Dulbecco's Modified Eagle Medium with high glucose supplemented with 1 mM glutamine, 10% (vol/vol) heat-inactivated bovine calf serum, Penicillin/Streptomycin, 50 μg/ml hygromycin and 15 μg/ml blasticidin (all cell culture reagents and antibiotics from Invitrogen, Basel, Switzerland). bout 24 hrs before an experiment, 5×104 cells/well were seeded in poly-D-lysine coated, black/clear-bottomed 96-well plates. The cells were loaded with 2.5 μM Fluo-4AM in loading buffer (1×HBSS, 20 mM HEPES) for 1 hr at 37 °C. and washed five times with loading buffer. The cells were transferred into a Functional Drug Screening System 7000 (Hamamatsu, Paris, France), and 11 half logarithmic serial dilutions of test compound at 37 °C. were added and the cells were incubated for 10-30 min. with on-line recording of fluorescence. Following this pre-incubation step, the agonist L-glutamate was added to the cells at a concentration corresponding to EC20 (typically around 80 μM) with on-line recording of fluorescence; in order to account for day-to-day variations in the responsiveness of cells, the EC20 of glutamate was determined immediately ahead of each experiment by recording of a full dose-response curve of glutamate. Responses were measured as peak increase in fluorescence minus basal (i.e. fluorescence without addition of L-glutamate), normalized to the maximal stimulatory effect obtained with saturating concentrations of L-glutamate.

Assay: Receptor Assay: Engagement of the LPA5 receptor by its ligand, oleoyl-L-Î±-lysophosphatidic acid (LPA), leads to the release of intracellular stores of calcium into the cytoplasm mediated through a Gq-driven increase in inositol triphosphate (IP3) levels. Gq is a heterotrimeric G protein subunit that activates phospholipase C.The ability of test compounds to prevent LPA-driven intracellular release of stored calcium from RH7777 cells expressing human LPA5 receptors was assayed by stimulating the cells with LPA in the presence of various test compounds to measure the test compounds' antagonism, i.e. activity in vitro. Approximately 10,000 cells in normal culture medium (Minimal Essential Media, 10% Foetal Calf Serum) were dispensed per assay well in a black clear bottom poly-D-lysine coated 384 well plate (Corning). Cells were allowed to settle for thirty minutes at room temperature before being incubated overnight at 37° C., 5% CO2.

Binding of the tracer and antibody to a kinase results in a high degree of FRET, whereas displacement of the tracer with a kinase inhibitor results in a loss of FRET.Assay conditions and materials used were as follows: Final Assay Conditions:GST-LRRK2 G2019S 10 nM; Eu-anti-GST-antibody 2 nMKinase tracer 236 8.5 nM; Kinase reaction time: 1 hour; Temperature: ambient; Total volume: 15 ul; DMSO: 1%; Materials: 384 well proxiplates F black shallow well Perkin Elmer cat#6008260Kinase: LRRK2 G2019S Invitrogen cat #PV4882(LOT 567054A). Eu-labeled anti-GST antibody Invitrogen cat #PV5594Alexa Fluor.

Assay: LANCE ULight TR-FRET Kinase Assay : CDK9 enzyme activities were measured using LANCE ULight TR-FRET kinase assay reagents (PerkinElmer, Waltham, Mass.). Compounds were diluted in 100% DMSO then diluted with 1:10 in serine/threonine kinase assay buffer containing 20 mM HEPES, 10 mM MgCl2, 100 mM Na3VO4, and 0.0075% Triton X-100. Equal volume of the compound dilutions was added to a final reaction mixture containing LANCE detection buffer (PerkinElmer CR97-100), 100 nM ULight MBP (PerkinElmer TRF0109M), 1000 μM ATP, and CDK9/Cyclin T1 (Carna Biosciences 04-110). The kinase reaction was carried out for 1 hour before addition of stopping buffer to a final of 20 mM EDTA and 0.5 nM of LANCE Ultra Europium anti-phospho-MBP antibody (PerkinElmer TRF0201M) in LANCE detection buffer. The reaction was incubated for 1 hour and the signal was read in Envision in TR-FRET mode (excitation at 320 nm and emission at 615/665 nm).
