UniProt: P43405
Assay: Homogeneous Time-Resolved Fluorescence (HTRF) Assay: A recombinant GST-hSyk fusion protein was used to measure potency of compounds to inhibit human Syk activity. The recombinant human GST-Syk (Carna Biosciences #08-176) (5 pM final concentration) was incubated with various concentrations of the inhibitor diluted in DMSO (0.1% final concentration) for 10 minutes at room temperature in 15 mM Tris-HCl (pH 7.5), 0.01% tween 20, 2 mM DTT in 384 well plate format. To initiate the reaction the biotinylated substrate peptide (250 nM final concentration) that contains the phosphorylation site for Syk was added with magnesium (5 mM final concentration) and ATP (25 uM final concentration). Final volume of the reaction was 10 uL. Phosphorylation of the peptide was allowed to proceed for 45x at room temperature. To quench the reaction and detect the phosphorylated product, 2 nM of a Europium-anti-phosphotyrosine antibody (Perkin Elmer #AD0161) and 70 nM SA-APC (Perkin-Elmer #CR130-100) were added together in 15 mM Tris pH 7.5.

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.

Assay: Kinase Assay (New): Compound potency against activated ERK2 is determined using a kinase assay that measures ERK2-catalyzed phosphorylation of biotinylated ERKtide peptide substrate ([Biotin]-AHA-K-R-E-L-V-E-P-L-T-P-S-G-E-A-P-N-Q-A-L-L-R-[NH2], the peptide sequence derived from EGF receptor: SEQ ID NO:1). The assay is carried out in 50 mM HEPES [pH 7.5], 5 mM MgCl2, 1 mM DTT, 0.01% Tween-20, 0.05% BSA using 0.25 nM ERK2, 200 nM ERKtide peptide and 35 uM ATP (all concentrations are final in the reaction) in a total volume of 10.25 uL. A 16-point, half-log dilution series of compounds at 41x final concentration is used for generating IC50 curves. Compound dilution series are prepared in 100% DMSO. ERK2 is preincubated with compounds for 30 minutes at ambient temperature. Reaction is initiated by addition of a substrate cocktail of ERKtide peptide and ATP and is allowed to proceed for 2-3 hours at ambient temperature. Reaction is terminated by addition of 10 uL of a 2x stop buffer consisting of 100 mM Tris-Cl [pH 7.5], 25 mM EDTA, 0.01% Tween 20, 10 ug/mL of AlphaScreen Protein A Acceptor Beads, 10 ug/mL of Streptavidin Donor Beads (PerkinElmer, Waltham, Mass.), and 1.4 ug/mL phospho-EGF Receptor (Thr669) antibody (Cat #3056, Cell Signaling Technology, Danvers, Mass.). Terminated reactions are read, after overnight incubation in the dark, on an EnVision Multilabel Plate Reader (PerkinElmer, Waltham, Mass.), with excitation and emission wavelengths set to 680 nm and 570 nm, respectively. IC50 values are determined using a four-parameter fit.

Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
Assay: PIM Enzyme Assay: 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 96-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 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.

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: 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.

First, 25 ul of test compound, previously diluted in Binding-Buffer (Binding-Buffer: 50 mM Tris-Base, 100 mM NaCl, 1 mM EDTA, 0.1% BSA (protease free), 0.01% NaN3, 10 mM MnCl2, pH 7.0) was placed into each well. After addition of 75 ul Binding-Buffer, 50 ul of the radioligand 3H-PGD2 (at 2.5 nM (220.000 dpm/well) from ANAWA ART0662) was added to each well. Binding assay was started by addition of 100 ul CRTH2 membrane fragments, reaching a final concentration of 20 ug/well. For non-specific binding, PGD2 was added to the reaction mixture to 10 mM final concentration. This assay mix was incubated for 90 minutes at room temperature and then filtered through a GF/C filter 96-well plate which was pre-soaked for 3 hours in 0.5% polyethyleneimine (PEI). The filter-wells were washed three times with ice cold Binding-Buffer. Then, 40 ul of Microscint-40 (Packard) was added to each well and the retained radioactivity quantified in a Topcount (Packard).

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: Renin (SINGLE PROTEIN), Homo sapiens
UniProt: P00797
Assay: Inhibitory Assay: A substrate of synthetic peptide (Nma-KHPFHLVIHK(Dnp)-NH2) and test compound were mixed, and fluorescence intensity was assayed using a fluorophotometer before staring an enzymatic reaction (exciting wavelength: 340 nm, measuring wavelength: 460 nm). Recombinant human renin was added and the mixture was incubated at 37° C. for 1 hour, and the fluorescence intensity was measured after the reaction using a fluorophotometer (exciting wavelength: 340 nm, measuring wavelength: 460 nm). Renin activity was evaluated on the ground of fluorescence intensity which was obtained by deduction of the intensity before the reaction from the intensity after the reaction, and 50% inhibitory concentration (IC50) was calculated from renin activities under the existence of various concentration of the test compound.
