Assay: FRET-Based Membrane Potential Assay: Two days prior to the experiment, frozen HEK293 cells stably expressing recombinant human Nav1.7 were quickly thawed and plated at 25,000 cells/well in growth medium [DMEM (Invitrogen #11965) with 10% HI FBS (Invitrogen #10082), 2 mM glutamine, 100 units/mL penicillin, 0.1 mg/mL streptomycin (PSG, Sigma #G1146), and 500 ug/mL Geneticin (Invitrogen #10131)] in black-walled, clear-bottom 384-well poly-D-lysine-coated assay plates (Greiner Bio-One, Frickenhausen, Germany) and incubated in a humidified 5% CO2 incubator at 37° C. On the day of the assay, medium was removed by aspiration, and cells were washed with assay buffer [HBSS (Invitrogen, Carlsbad, Calif.) containing 20 mM HEPES (Invitrogen, Carlsbad, Calif.)]. After washing, 30 uL assay buffer containing the fluorescent voltage-sensor probe CC2-DMPE (Invitrogen, Carlsbad, Calif.) at 20 uM and 0.01% pluronic F-127 (Invitrogen, Carlsbad, Calif.) was added to the cells. Cells were incubated for 40 minutes at room temperature in the dark. Following the incubation, the cells were washed and 30 uL assay buffer containing 2.5 uM DiSBAC2(3) substrate (Invitrogen, Carlsbad, Calif.) and 0.5 mM VABSC-1 (Invitrogen, Carlsbad, Calif.) was added to the cells. The cells were incubated for 90 minutes at room temperature in the dark. Fluorescence readings were made using a FLIPR TETRA (Molecular Devices, Sunnyvale Calif.) equipped with voltage-sensor probe optics. At the start of each experiment the optimal (EC80) concentration of depolarizing agent (veratridine) was determined by testing a dilution curve of assay buffer containing veratridine (Sigma-Aldrich, St. Louis, Mo.) and 1 mg/mL scorpion venom (SVqq, from Leiurus quinquestriatus; Sigma-Aldrich, St. Louis, Mo.). Compounds were dissolved in dimethyl sulfoxide, and 8-point, 1:3 dilution concentration-response curves were prepared in duplicate in dimethyl sulfoxide, followed by preparation of 0.8 uL/well daughter plates of the dilutions. Test compounds in the daughter plate were diluted to (Ë¿3x) solutions in assay buffer immediately before assaying. Using the FLIPR TETRA, 20 uL of the (3x) compound solutions were first added to the cells, then 20 uL of depolarizing solution (3xEC80 veratridine+SVqq) were added 3 minutes later to activate the channel. Changes in fluorescence were measured at wavelengths of 440-480 nm and 565-625 nm over the course of the experimental run. Membrane depolarization was expressed as a ratio of the maximum F440-480 nm/F565-625 nm reading above average baseline F440-480 nm/F565-625 nm reading. IC50 values were calculated from curve fits of the ratio data using a four-parameter logistic Hill equation (Accelrys Assay Explorer 3.3 Client, Accelrys, San Diego, Calif.) with percent inhibition plotted against compound concentration.

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: LANCE-TR-FRET Assay: Assay Method B: BTK enzymatic activity was determined with the LANCE (Lanthanide Chelate Excite) TR-FRET (Time-resolved fluorescence resonance energy transfer) assay. In this assay, the potency (IC50) of each compound was determined from an eleven point (1:3 serial dilution; final compound concentration range in assay from 1 μM to 0.017 nM) titration curve using the following outlined procedure. To each well of a black non-binding surface Corning 384-well microplate (Corning Catalog #3820), 5 nL of compound (2000 fold dilution in final assay volume of 10 μL) was dispensed, followed by the addition of 7.5 μL of 1× kinase buffer (50 mM Hepes 7.5, 10 mM MgCl2, 0.01% Brij-35, 1 mM EGTA, 0.05% BSA & 1 mM DTT) containing 5.09 pg/μL (66.67 pM) of BTK enzyme (recombinant protein from baculovirus-transfected Sf9 cells: full-length BTK, 6HIS-tag cleaved). Following a 60 minute compound & enzyme incubation, each reaction was initiated by the addition of 2.5 μL 1× kinase buffer containing 8 μM biotinylated "A5" peptide (Biotin-EQEDEPEGDYFEWLE-NH2), and 100 μM ATP. The final reaction in each well of 10 μL consists of 50 pM hBTK, 2 μM biotin-A5-peptide, and 25 μM ATP. Phosphorylation reactions were allowed to proceed for 120 minutes. Reactions were immediately quenched by the addition of 20 μL of 1× quench buffer (15 mM EDTA, 25 mM Hepes 7.3, and 0.1% Triton X-100) containing detection reagents (0.626 nM of LANCE-Eu-W1024-anti-phosphoTyrosine antibody, PerkinElmer and 86.8 nM of Streptavidin-conjugated Dylight 650, Dyomics/ThermoFisher Scientific). After 60 minutes incubation with detection reagents, reaction plates were read on a PerkinElmer EnVision plate reader using standard TR-FRET protocol. Briefly, excitation of donor molecules (Eu-chelate:anti-phospho-antibody) with a laser light source at 337 nm produces energy that can be transferred to Dylight-650 acceptor molecules if this donor:acceptor pair is within close proximity. Fluorescence intensity at both 665 nm (acceptor) and 615 nm (donor) are measured and a TR-FRET ratio calculated for each well (acceptor intensity/donor intensity).

Assay: Calcium Mobilization Assay: Functional modulation of CXCR4 was determined by calcium mobilization assay using leukemic lymphoid CEM cells, which naturally express high levels of CXCR4. Generally, the assay is carried out as follows: Cells are grown in vitro to confluency. On the day of the assay, cells are removed from the incubator, culture medium removed and replaced with a calcium sensitive dye (Calcium3 assay kit; Molecular Devices, Sunnyvale, Calif.). The cells are allowed to dye load for 45-60 min at 37 °C. in the cell culture incubator and then allowed to equilibrate to room temperature for no more than 15 min before assay. Compound plates were generated containing up to 3% dimethyl sulfoxide in media kept at room temperature. Test compounds were added to the cells at a 1:3 dilution, and calcium mobilization was measured using a Flex Station fluorescence imager (Molecular Devices). This first read was used to determine direct agonist activation of the CXCR4 receptor by the test compounds.

UniProt: Q9H1C0
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. Sixteen to twenty hours after dispensing, the cells were loaded with a calcium-sensitive fluorescent dye by replacing the culture medium with assay buffer (1x Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH7.4) containing 1.25 mM probenecid and 1x Calcium 5 Reagent (Molecular Devices). Cells were incubated at 37° C. for one hour to allow for dye uptake.

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.

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.

UniProt: P03951
Assay: In Vitro Assay: The effectiveness of compounds of the present invention as inhibitors of the coagulation Factors XIa, VIIa, IXa, Xa, XIIa, plasma kallikrein or thrombin, can be determined using a relevant purified serine protease, respectively, and an appropriate synthetic substrate. The rate of hydrolysis of the chromogenic or fluorogenic substrate by the relevant serine protease was measured both in the absence and presence of compounds of the present invention. Hydrolysis of the substrate resulted in the release of pNA (para nitroaniline), which was monitored spectrophotometrically by measuring the increase in absorbance at 405 nm, or the release of AMC (amino methylcoumarin), which was monitored spectrofluorometrically by measuring the increase in emission at 460 nm with excitation at 380 nm. A decrease in the rate of absorbance or fluorescence change in the presence of inhibitor is indicative of enzyme inhibition. Factor XIa determinations were made in 50 mM HEPES buffer at pH 7.4.

UniProt: O75874
Assay: Fluorescence Biochemical Assay: The IDH1 (R132H) mutant catalyzes the reduced form of NADP+ (NADPH) and α-ketoglutarate (α-KG) to form nicotinamide adenine dinucleotide phosphate (NADP+) and R (−)-2-hydroxyglutarate (2HG). The reaction can be monitored kinetically by following the oxidation of NADPH to NADP+ which is measured using fluorescence, excitation at 355 nm and emission at 530 nm. Reactions were monitored using the Perkin-Elmer Envision, Model 2101. More specifically, the biochemical reactions were performed at room temperature in 384-well Greiner flat-bottom plates (Cat. No. 781076) using a final reaction volume of 20 μL and the following assay buffer conditions: 50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM DTT, 0.02% BSA, 0.02% Tween-20, 10 μM NADPH and 100 μM α-KG. The final reaction mixture contained 2.5% DMSO and test compounds with concentrations ranging 0.0000008-25 μM. The IDH1 (R132H) enzyme was used at a final concentration of 10 nM.
