Target: Tyrosine-protein kinase JAK1 (SINGLE PROTEIN), Homo sapiens
UniProt: P23458
Assay: Biochemical JAK and Tyk2 Kinase Assays: A panel of four LanthaScreen JAK biochemical assays (JAK1, 2, 3 and Tyk2) were carried in a common kinase reaction buffer (50 mM HEPES, pH 7.5, 0.01% Brij-35, 10 mM MgCl2, and 1 mM EGTA). Recombinant GST-tagged JAK enzymes and a GFP-tagged STAT1 peptide substrate were obtained from Life Technologies. Serially or discretely diluted compounds were pre-incubated with each of the four JAK enzymes and the substrate in white 384-well microplates (Corning) at ambient temperature for 1 h. ATP was subsequently added to initiate the kinase reactions in 10 μL total volume, with 1% DMSO. The final enzyme concentrations for JAK1, 2, 3 and Tyk2 are 4.2 nM, 0.1 nM, 1 nM, and 0.25 nM respectively; the corresponding Km ATP concentrations used are 25 μM, 3 μM, 1.6 μM, and 10 μM; while the substrate concentration is 200 nM for all four assays. Kinase reactions were allowed to proceed for 1 hour at ambient temperature before a 10 μL preparation of EDTA (10 mM final concentration) and Tb-anti-pSTAT1 (pTyr701) antibody (Life Technologies, 2 nM final concentration) in TR-FRET dilution buffer (Life Technologies) was added. The plates were allowed to incubate at ambient temperature for 1 h before being read on the EnVision reader (Perkin Elmer). Emission ratio signals (520 nm/495 nm) were recorded and utilized to calculate the percent inhibition values based on DMSO and background controls.For dose-response analysis, percent inhibition data were plotted vs. compound concentrations, and IC50 values were determined from a 4-parameter robust fit model with the Prism software (GraphPad Software). Results were expressed as pIC50 (negative logarithm of IC50) and subsequently converted to pKi (negative logarithm of dissociation constant, Ki) using the Cheng-Prusoff equation.

Assay: Cell Based Assay: Ca2+ signaling studies were performed using a FLIPR TETRA system (Molecular Devices, Sunnyvale, Calif., USA) in the 384-format. This is a high-throughput instrument for cell-based assays to monitor Ca2+ signaling associated with GPCRs and ion channels. Cells were seeded at a density of 5×104 cells/well in BioCoat poly-D-lysine coated, black wall, clear bottom 384-well plates (BD Biosciences, Franklin lakes, NJ, USA) and allowed to attach overnight in an incubator at 37° C. The cells were then washed twice with HBSS-HEPES buffer (Hanks' balanced salt solution without bicarbonate and phenol red, 20 mM HEPES, pH 7.4) using an ELx405 Select CW Microplate Washer (BioTek, Winooski, Vt., USA). After 60 min of dye-loading in the dark using the Ca2+-sensitive dye Fluo-4AM (Invitrogen, Carlsbad, Calif., USA), at a final concentration of 2×10^−6M, the plates were washed 4 times with HBSS-HEPES buffer to remove excess dye and leaving 50 μl of buffer in each well. The plates were then placed in the FLIPR TETRA instrument and allowed to equilibrate at 37° C. AGN-211377 was added in a 25 μl volume to each well to give final concentrations of 0.1 μM, 0.3 μM, 1 μM, 3 μM, 10 μM, and 30 μM; or 0.067 μM, 0.1 μM, 0.2 μM, 0.3 μM, 0.67 μM, and 1 μM for cells over-expressing TP receptors. After 4.5 minutes, a 7-point serial dilution of the standard agonist for the corresponding receptor, in a 25 μl volume was injected at the final concentrations from 10^−11M to 10^−5M in 10-fold serial dilution increments for cells expressing human recombinant DP1, EP1, EP2, EP3, EP4, FP, and IP receptors. The dose range for the standard agonist for human recombinant TP receptors was from 10^−12M to 10^−6M. HBSS-HEPES buffer was used as the negative control for the standard agonists. Cells were excited with LED (light emitting diode) excitation at 470-495 nm and emission was measured through an emission filter at 515-575 nm. Assay plates were read for 3.5 minutes using the FLIPRTETRA.

Assay: Binding Assay: The binding assays were performed by testing the ability of the new compounds to displace the radiolabeled synthetic non-selective cannabinoid agonist [3H]CP55940 (168 Ci/mmol; PerkinElmer) from the human CB1 (hCB1) or human CB2 (hCB2) receptors on membranes derived from stably transfected HEK-293 cells (PerkinElmer). Membranes were diluted in assay buffer (50 mM Tris-HCl, 1 mM EDTA, 1 mM MgCl2, 1 mg/ml BSA, pH=7.4). The amount of membrane was determined for each batch of membranes according to protein binding assay. The minimum amount of membrane that gave 50% specific binding was used for the binding assay. In most assays, binding was tested using 8 μg and 4 μg protein of hCB1 and hCB2 membranes, respectively. The tested compounds were dissolved in DMSO and diluted in assay buffer to a final concentration of 0.1% solvent. Total binding of [3H]CP55940 was evaluated with 1.5 nM to hCB1 and with 0.5 nM to hCB2, according to Kd affinity of [3H]CP55940 for the respective membranes. The ability of the tested compounds to displace [3H]CP55940 was evaluated first at a single concentration point of 100 nM for binding toward hCB2 or hCB1. In certain cases, the displacement was tested at compound concentrations ranging from 0.03 nM to 10 μM. Non-specific binding was measured by the addition of 1 μM of unlabelled CP55940 to the tubes. Binding assays were performed in triplicate in a total volume of 500 μl for 60 minutes at 30° C., in a shaking bath. Free and bound radioligands were separated by rapid filtration through GF/C filter plates (PerkinElmer) that had been presoaked with 0.1% Polyethylenimine (Sigma). Filters were shaken for 1 hour in 7 ml scintillation fluid (PerkinElmer) and radioactivity was determined by liquid scintillation counter (Wallac; PerkinElmer).

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.

Assay: ERK2 (20 pM) Kinase Assay: Compound potency against activated ERK2 was 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 was carried out in 20 mM HEPES [pH 7.5], 5 mM MgCl2, 1 mM DTT, 0.01% Tween-20, 0.05% BSA using 0.02 nM ERK2, 400 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 was used for generating IC50 curves. Compound dilution series were prepared in 100% DMSO. ERK2 was preincubated with compounds for 30 minutes at ambient temperature. Reaction was initiated by addition of a substrate cocktail of ERKtide peptide and ATP and was allowed to proceed for 4 hours at ambient temperature. Reaction was 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, 20 ug/mL of AlphaScreen Protein A Acceptor Beads, 20 ug/mL of Streptavidin Donor Beads (PerkinElmer, Waltham, Mass.), and 1:1000 dilution phospho-EGF Receptor (Thr669) antibody (Cat #8808, Cell Signaling Technology, Danvers, Mass.). Terminated reactions were 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 were determined using a four-parameter fit.

Assay: Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) Assay: The activities were measured using a time-resolved fluorescence resonance energy transfer (TR-FRET) assay. TR-FRET monitored the formation of 3,4,5-inositol triphosphate molecule that competed with fluorescently labeled PIP3 for binding to the GRP-1 pleckstrin homology domain protein. An increase in phosphatidylinositide 3-phosphate product resulted in a decrease in TR-FRET signal as the labeled fluorophore was displaced from the GRP-1 protein binding site. Class I PI3K isoforms were expressed and purified as heterodimeric recombinant proteins. All assay reagents and buffers for the TR-FRET assay were purchased from Millipore. PI3K isoforms were assayed under initial rate conditions in the presence of 25 mM Hepes (pH 7.4), and 2xKm ATP (75-500 uM), 2 uM PIP2, 5% glycerol, 5 mM MgCl2, 50 mM NaCl, 0.05% (v/v) Chaps, 1 mM dithiothreitol, and 1% (v/v) DMSO at the following concentrations for each isoform: PI3Kα, PI3Kβ, and PI3Kδ between 25 and 50 uM, and PI3Kγ at 2 nM. The compounds of Table 1 and Compound X ((S)-2,4-diamino-6-((1-(5-chloro-4-oxo-3-(pyridin-3-yl)-3,4-dihydroquinazolin-2-yl)ethyl)amino)pyrimidine-5-carbonitrile) and Compound Y ((S)-2,4-diamino-6-((1-(5-chloro-4-oxo-3-(pyridin-3-yl)-3,4-dihydroquinazolin-2-yl)ethyl)amino)pyrimidine-5-carbonitrile) were added to the assay solution and incubated for 30 minutes at 25° C. The reactions were terminated with a final concentration of 10 mM EDTA, 10 nM labeled-PIP3, and 35 nM Europium labeled GRP-1 detector protein before reading TR-FRET on an Envision plate reader (Ex: 340 nm; Em: 615/665 nm; 100 us delay and 500 us read window). The results were normalized based on positive (1 uM wortmanin) and negative (DMSO) controls, and the IC50 values for PI3K α, β, δ and γ were calculated from the fit of the dose-response curves to a four-parameter equation.

Assay: Binding Assay: The binding assays were performed by testing the ability of the new compounds to displace the radiolabeled synthetic non-selective cannabinoid agonist [3H]CP55940 (168 Ci/mmol; PerkinElmer) from the human CB1 (hCB1) or human CB2 (hCB2) receptors on membranes derived from stably transfected HEK-293 cells (PerkinElmer). Membranes were diluted in assay buffer (50 mM Tris-HCl, 1 mM EDTA, 1 mM MgCl2, 1 mg/ml BSA, pH=7.4). The amount of membrane was determined for each batch of membranes according to protein binding assay. The minimum amount of membrane that gave 50% specific binding was used for the binding assay. In most assays, binding was tested using 8 μg and 4 μg protein of hCB1 and hCB2 membranes, respectively. The tested compounds were dissolved in DMSO and diluted in assay buffer to a final concentration of 0.1% solvent. Total binding of [3H]CP55940 was evaluated with 1.5 nM to hCB1 and with 0.5 nM to hCB2, according to Kd affinity of [3H]CP55940 for the respective membranes. The ability of the tested compounds to displace [3H]CP55940 was evaluated first at a single concentration point of 100 nM for binding toward hCB2 or hCB1. In certain cases, the displacement was tested at compound concentrations ranging from 0.03 nM to 10 μM. Non-specific binding was measured by the addition of 1 μM of unlabelled CP55940 to the tubes. Binding assays were performed in triplicate in a total volume of 500 μl for 60 minutes at 30° C., in a shaking bath. Free and bound radioligands were separated by rapid filtration through GF/C filter plates (PerkinElmer) that had been presoaked with 0.1% Polyethylenimine (Sigma). Filters were shaken for 1 hour in 7 ml scintillation fluid (PerkinElmer) and radioactivity was determined by liquid scintillation counter (Wallac; PerkinElmer).

UniProt: P08684
Assay: CYP3A4 Inhibition Assay: The CYP3A4 inhibition assay was performed using human liver microsomes and testosterone 6'-hydroxylation as a P450 isoform-specific marker. In a total volume of 150 uL, 14C-testosterone at a final concentration of 40 uM in a 100 mM phosphate buffer (pH 7.4) was incubated in a 96-well plate with 0.3 mg/mL of human liver microsomes in an Eppendorf thermomixer at 37° C. and 400 rpm. A 1.0 uL-aliquot of the 150-fold concentrated compound stock solution, prepared in DMSO, was added to yield final inhibitor concentrations of 0, 0.1, 0.5, 1.0, 5.0, 10, 25, and 50 uM. The reaction was initiated by addition of 15 uL of the NADPH-regenerating system containing the glucose-6-phosphate dehydrogenase and terminated after 7 min with a 75 uL-aliquot of methanol. After centrifugation at 465 g and 4° C. for 20 min, a 50 uL-aliquot of the supernatant was submitted to HPLC according to the method described below.
