Target: Coagulation factor XI (SINGLE PROTEIN), Homo sapiens
UniProt: P03951
Assay: Measurement of FXIa Inhibition: To determine the factor XIa inhibition of the substances according to the invention, a biochemical test system is used which utilizes the reaction of a peptidic factor XIa substrate to determine the enzymatic activity of human factor XIa. Here, factor XIa cleaves from the peptic factor XIa substrate the C-terminal aminomethylcoumarin (AMC), the fluorescence of which is measured. The determinations are carried out in microtitre plates.Test substances are dissolved in dimethyl sulphoxide and serially diluted in dimethyl sulphoxide (3000 μM to 0.0078 μM; resulting final concentrations in the test: 50 μM to 0.00013 μM). In each case 1 μl of the diluted substance solutions are placed into the wells of white microtitre plates from Greiner (384 wells). 20 μl of assay buffer (50 mM of Tris/HCl pH 7.4; 100 mM of sodium chloride solution; 5 mM of calcium chloride solution; 0.1% of bovine serum albumin) and 20 μl of factor XIa from Kordia (0.45 nM in assay buffer) are then added successively. After 15 min of incubation, the enzyme reaction is started by addition of 20 μl of the factor XIa substrate Boc-Glu(OBzl)-Ala-Arg-AMC dissolved in assay buffer (10 μM in assay buffer) from Bachem, the mixture is incubated at room temperature (22° C.) for 30 min and fluorescence is then measured (excitation: 360 nm, emission: 460 nm). The measured emissions of the test batches with test substance are compared to those of control batches without test substance (only dimethyl sulphoxide instead of test substance in dimethyl sulphoxide), and the IC50 values are calculated from the concentration/activity relationships.

Assay: Biological Assay: 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 (1× Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH 7.4) containing 1 mM probenecid and 1× 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 μM (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 to excitation at 485 nM.

Assay: Fluorescence Assay A1 for Recombinant Human (RH) DPP1: The activity of DPP1 was determined by measuring the enzymatic release of aminomethyl coumarin (AMC) from the peptide substrate (H-Gly-Arg-AMC), which leads to an increase in fluorescence intensity at λex=350 nm and λem=450 nm. The assay was carried out in black 384 well plates in a final volume of 50 μl at 22° C. The assay conditions contained the following: 25 mM piperazine buffer pH 5.0; 50 mM NaCl, 5 mM DTT; 0.01% (v/v) Triton X-100; 100 μM H-Gly-Arg-AMC and rhDPP1 (50 pM). Potential inhibitors were made up in DMSO and then diluted in the assay to give a final concentration of not exceeding 1% (v/v) DMSO. A 10-point half-log dilution series of the inhibitors (highest concentration typically 10 μM) was tested and the pIC50 determined using a 4-paramater logistic equation in a non-linear curve fitting routine. A standard DPP1 inhibitor, 4-amino-N-[(1S)-1-cyano-2-(4′-cyanobiphenyl-4-yl)ethyl]tetrahydro-2H-pyran-4-carboxamide (WO2010/128324, Ex. 3) was used as a positive control in the assay. Routinely, inhibitors were pre-incubated with rhDPP1 for 30-60 min prior to the addition of the peptide substrate to start the reaction for a further 60 min at 22° C. After that the plates were immediately read in a fluorescence plate reader using the above emission and excitation wavelengths [modified from Kam, CM, Gotz, MG, Koot, G, McGuire, M J, Thiele, D L, Hudig, D & Powers, J C (2004).

Assay: Measurement of FXIa Inhibition: To determine the factor XIa inhibition of the substances according to the invention, a biochemical test system is used which utilizes the reaction of a peptidic factor XIa substrate to determine the enzymatic activity of human factor XIa. Here, factor XIa cleaves from the peptic factor XIa substrate the C-terminal aminomethylcoumarin (AMC), the fluorescence of which is measured. The determinations are carried out in microtitre plates.Test substances are dissolved in dimethyl sulphoxide and serially diluted in dimethyl sulphoxide (3000 μM to 0.0078 μM; resulting final concentrations in the test: 50 μM to 0.00013 μM). In each case 1 μl of the diluted substance solutions are placed into the wells of white microtitre plates from Greiner (384 wells). 20 μl of assay buffer (50 mM of Tris/HCl pH 7.4; 100 mM of sodium chloride solution; 5 mM of calcium chloride solution; 0.1% of bovine serum albumin) and 20 μl of factor XIa from Kordia (0.45 nM in assay buffer) are then added successively. After 15 min of incubation, the enzyme reaction is started by addition of 20 μl of the factor XIa substrate Boc-Glu(OBzl)-Ala-Arg-AMC dissolved in assay buffer (10 μM in assay buffer) from Bachem, the mixture is incubated at room temperature (22° C.) for 30 min and fluorescence is then measured (excitation: 360 nm, emission: 460 nm). The measured emissions of the test batches with test substance are compared to those of control batches without test substance (only dimethyl sulphoxide instead of test substance in dimethyl sulphoxide), and the IC50 values are calculated from the concentration/activity relationships.

Target: Bromodomain-containing protein 4 (SINGLE PROTEIN), Homo sapiens
UniProt: O60885
Assay: Amplified Luminescent Proximity Homogeneous Assay (ALPHA): Binding of the bromodomain BRD4-I to an acetylated histone H4 peptide was measured using a bead-based Amplified Luminescent Proximity Homogeneous Assay (ALPHA). The synthetic peptide containing amino acids 1-18 of histone H4 was acetylated at lysine 5, 8, 12, 16 and conjugated to biotin (SGRGACKGGACKGLGACKGGAACKRH-GSGSK-biotin[SEQ ID NO:1]) was purchased from Millipore. BRD4-I was expressed and purified from Escherichia coli as an N-terminal His6-tagged protein. Nickel-Chelate ALPHA acceptor beads (Perkin Elmer) were used to specifically bind BRD4-1 and ALPHA streptavidin donor beads (Perkin Elmer) were used because they specifically recognized the biotinylated H4 peptide. Binding of BRD4-1 to the peptide resulted in proximity of the donor and acceptor beads which leads to an increase in ALPHA signal whereas disruption of this protein-peptide interaction with a small molecule inhibitor resulted in a decrease in ALPHA signal. Assays were performed in 50 mM Hepes (pH 7.5), 150 mM NaCl, 0.1 mg/ml BSA, 0.01% (v/v) Brij, 0.5% (v/v) DMSO, 200 nM H4 peptide and 15 nM of BRD4-1 protein. After an assay reaction time of 60 minutes at 25° C., binding was measured with 20 ug/ml streptavidin donor beads and 20 ug/ml nickle-chelate acceptor beads. ALPHA signal was detected on an Envision plate reader (Ex: 320 nm; Em: 570 nm; Ex time: 180 ms). Data were normalized based on a positive (2 uM I-BET) and negative (DMSO) controls and IC50 values were calculated from the fit of the dose-response curves to a four-parameter equation. All IC50 values represent geometric mean values of a minimum of four determinations.

At the end of incubation (5 minutes for 3A4; 45 minutes for 2C19; 10 minutes for 1A2, 2C9, 2D6), 120 μL of acetonitrile was added into corresponding wells. After the final time point was sampled, the plates were shaken at a vibrator (IKA, MTS 2/4) for 10 mM (600 rpm/min) and then centrifuged at 5594 g for 15 mM (Thermo Multifuge×3R). Aliquots of the supernatant were removed, diluted 1:1 into distilled water, and analyzed by LC-MS/MS. The peak area response ratio to internal standard (PARR) of the compounds at 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, 0.122 μM, 0.041 μM, and 0.0136 μM was compared to the PARR at 0 μM to determine the percent of metabolite generation from substrate at each test compound concentration.

Assay: ADP-Glo Kinase Assay: Inhibitor Concentration at 50% enzyme inhibition (IC50) values were calculated by quantifying the end-point ADP production from each kinase reaction using the ADP-Glo Kinase Assay (Promega, Madison, Wis.) as described by the manufacturer. Reactions were performed in Tris buffer (50 mM pH 7.5, RT) containing 20 mM MgCl2 and 0.1% Bovine Serum Albumin. Each assay was performed in 60 uL of the solution in 10x75 mm borosilicate glass test tubes and allowed to continuously shake during the duration of the assay. The total ADP generated was quantified by transferring 25 uL (2x) of each assay to a 96-well luminescence assay plate, followed by the addition of 25 uL of ADP-Glo Reagent (45 min incubation) to remove any remaining ATP. For luminescence readings, 50 uL of Kinase Detection Reagent (45 min incubation) was added to convert the ADP generated from the kinase reaction to ATP, and luminescent intensity was measured using a luciferase/luciferin reaction.

UniProt: Q06187
Assay: Kinase Assay: Compounds disclosed herein were tested for inhibition of Btk kinase activity in an assay based on time-resolved fluorescence resonance energy transfer methodology. Recombinant Btk was pre-incubated with the compounds disclosed herein at room temperature for 1 hour in an assay buffer containing 50 mM Tris pH7.4, 10 mM MgCl2, 2 mM MnCl2, 0.1 mM EDTA, 1 mM DTT, 20 nM SEB, 0.1% BSA, 0.005% tween-20. The reactions were initiated by the addition of ATP (at the concentration of ATP Km) and peptide substrate (Biotin-AVLESEEELYSSARQ-NH2). After incubating at room temperature for 1 h, an equal volume of stop solution containing 50 mM HEPES pH7.0, 800 mM KF, 20 mM EDTA, 0.1% BSA, Eu cryptate-conjugated p-Tyr66 antibody and streptavidin-labeled XL665 was added to stop the reaction. Plates were further incubated at room temperature for 1 hour, and then the TR-FRET signals (ex337 nm, em 620 nm/665 nm) were read on BMG PHERAstar FS instrument. The residual enzyme activity in presence of increasing concentrations of compounds was calculated based on the ratio of fluorescence at 615 nm to that at 665 nm.
