Assay: JAK Caliper Enzyme Assay: Test article was solubilized in dimethyl sulfoxide (DMSO) to a stock concentration of 30 mM. An 11-point half log dilution series was created in DMSO with a top concentration of 600 μM. The test compound plate also contained positive control wells containing a known inhibitor to define 100% inhibition and negative control wells containing DMSO to define no inhibition. The compound plates were diluted 1 to 60 resulting in a top final assay compound concentration of 10 μM and a 2% DMSO concentration.Test article and assay controls were added to a 384-well plate. Reaction mixtures contained 20 mM HEPES, pH 7.4, 10 mM magnesium chloride, 0.01% bovine serum albumin (BSA), 0.0005% Tween 20, 4 μM ATP and 1 μM peptide substrate. The JAK3 assays contained 1 μM of the JAKtide peptide (FITC-KGGEEEEYFELVKK). The assays were initiated by the addition 1 nM JAK3 enzyme and were incubated at room temperature 75 minutes for JAK3. Enzyme concentrations and incubation times were optimized for each new enzyme preps and were modified slightly over time to ensure 20%-30% phosphorylation. The assays were stopped with a final concentration of 10 mM EDTA, 0.1% Coating Reagent and 100 mM HEPES, pH=7.4. The assay plates were placed on a Caliper Life Science Lab Chip 3000 (LC3000) instrument, and each well was sampled using appropriate separation conditions to measure the unphosphorylated and phosphorylated peptide.

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: Cytokine Assays: Cytokine inhibitory activity is determined by measuring the effect of test agent on the release of the cytokines IL-4, IL-13 and IFNγ from human peripheral blood mononuclear cells (PBMCs) stimulated with the T-cell mitogen phytohemagglutinin-L (PHA-L). At the time of assay, human PBMCs (Astarte Biologics) are removed from cryopreservation, thawed quickly at 37° C., diluted in assay medium (RPMI-Gibco 1640 medium, 10% heat inactivated fetal bovine serum (HIFBS), 2 mM glutamine and 10 mM HEPES pH 7.4) and then centrifuged at 250×g for 5 minutes. The resulting cell pellet is re-suspended in assay medium to a concentration of approximately 5×106 cells/mL and 50 μL of this cell suspension (approximately 250,000 cells) is added to each well of a 384-well cell culture microtiter plate (Perkin Elmer). Varying concentrations of test compound are then diluted in assay medium and added to the assay plate wells in a volume of 25 μL. After −10 minutes at room temperature (21° C.) the cells are stimulated by the addition of 25 μL of PHA-L (14 μg/mL; Millipore) and the assay plate is placed in an incubator at 37° C. in a humidified environment in 5% carbon dioxide. The final assay conditions are approximately 250,000 human PBMCs per well in assay medium containing 3.5 μg/mL PHA-L and the indicated final concentration of test compound (approximately 10 μM to 9.5 μM by 4-fold dilution). The final concentration of DMSO in the assay is approximately 0.25%. After 48 hours, the assay plate is removed from the incubator and centrifuged at 250×g for 5 minutes. A portion of the resulting cell supernatant is then used to determine the amount of IL-4, IL-13 and IFNγ in each well. Cytokine measurements are made using human IL-4, IL-13 or IFNγ HTRF assay kits (CisBio) following the manufacturer's assay protocol. The concentrations and resulting effect values for tested compounds are plotted and the concentration of compound required for 50% effect (IC50) is determined with a four-parameter logistic dose response equation (E-WorkBook, ID Business Solutions Ltd.).

Assay: Binding Assay: Receptor binding was performed using membrane fractions prepared from the HEK-293 cell line recombinantly expressing rat 5-HT7 receptors (NCBI accession NM_022938). Compound affinity for the rat 5-HT7 receptor subtype was evaluated by competitive radioligand binding assays using 5-carboxamido[3H]tryptamine ([3H]5-CT) (Amersham Biosciences, cat. 90000403) detection. HitHunter cAMP assays are in-vitro based competitive immunoassays. The assay was performed on the HEK-293 cell line stably transfected with r5-HT7 receptor. Cells were pre-incubated with test compounds for 10 minutes. For antagonist testing, the cells were then challenged with 100 nM 5-CT for 20 minutes. Cells were then lysed and cAMP measured according to manufacturers protocol (Amersham, cat. NET791250UC) or [3H]mesulergine (Amersham, cat. TRK1041). The assay was performed on membranes prepared from HEK-293 cells stably transfected with h5-HT6. Following centrifugation, membranes were resuspended and incubated for 60 min at room temperature with 1.7 nM [3H]LSD in the presence of increasing concentration of test compounds. Nonspecific binding was defined in the presence of 10 μM clozapine (Tocris, cat. TRK1068). Homogenized HEK-293 membranes expressing the human SERT were incubated in 50 mM Tris-HCl (pH 7.5), 120 mM NaCl, 5 mM KCl with [3H]-citalopram (3 nM) with or without test compounds. Nonspecific binding was determined in the presence of 10 μM fluoxetine. Radioactivity readouts and Ki values were performed as previously described for r5-HT7.

The reaction was stopped after 2 hours with a 20 μL addition of Quanta Red Stop solution (1:20 dilution in distilled water). The above-described mixture with DMSO alone was used as a positive control whereas that with DMSO alone without ATX was taken as a negative control. For each test compound, ten concentrations were measured covering a range of 6.1 nM to 120 μM to determine IC50 values. The top concentration was decreased to 1.2 μM when a test compound's IC50 value was evaluated in low nanomolar range. Fluorescence was determined in a BMG Labtech Pherastar plus plate reader (λ emission=540 nm, λ excitation=590 nm). Data were analysed using Excel fit software.

Assay: Biochemical Assay: The biochemical assay is in a AlphaScreen format. The kinase reaction is based on the IRAK-4 phosphorylation of a biotin labeled peptide. The phosphopeptide is incubated with anti-phosphothreonine antibody as well as streptavidin- and protein A-coated beads. Binding of the protein-A coated beads to the antibody and the streptavidin beads to the peptide, leads to an energy transfer from one bead to the other, ultimately producing a luminescent/fluorescent signal.Generally, the kinase reaction is carried out at 1 nM IRAK4, 1.6 μM peptide, 1 mM ATP in reaction buffer 50 mM Hepes, 60 mM NaCl, 5 mM MgCl2, 0.25 mM MnCl2, 2 mM DTT, 0.01% BSA, 0.01% Tween-20) for 3.5 h at RT.

Assay: Scintillation Proximity Assay (SPA): HIF-2a: The total assay volume was about 100 uL in the following configuration: 2 uL compound in 100% DMSO, 88 uL buffer with protein and probe and 10 uL of SPA beads. The compound was diluted in a master plate consisting of a 10-point dose response with a 3-fold compound dilution from 100 nM to 5 nM. Assays were run on a 96-well plate in which one column, designated as the high signal control, contained DMSO with no compound and another column, designated as the low signal control, contained no protein. Prior to plating out of compound, a buffer solution, consisting of 25 mM TRIS pH 7.5 (Sigma), 150 mM NaCl (Sigma), 15% Glycerol (Sigma), 0.15% BSA (Sigma), 0.001% Tween-20 (Sigma), 150 nM Compound 183 and 100 nM HIF-2Î± HIS TAG-PASB Domain, was made and allowed to equilibrate for 30 minutes. Compounds that were to be tested were then plated in to a 96-well white clear bottom Isoplate-96 SPA plate (Perkin Elmer). To the compounds, 88 uL of the buffer solution was then added, the plate was covered with a plastic cover and then aluminum foil, placed onto a shaker and equilibrated for 1 hour. After equilibration, 10 uL of a 2 mg/mL solution of YSi Cu His tagged SPA beads (Perkin Elmer) were then added to each well of the plate, covered and equilibrated for another 2 hours. The plates were then removed from the shaker, placed into a 1450 LSC and luminescence counter MicroBeta Trilux (Perkin Elmer) to measure the extent of probe displacement.

Compounds in 100% DMSO (1 ul) were spotted into a 384-well white opaque OptiPlate using a Bravo automated liquid handling platform outfitted with a 384-channel head (Agilent Technologies). DMSO (1 ul) was added to Columns 11, 12, 23, 24, rows A-H for the maximum signal control and 1 ul of SAH, a known product and inhibitor of SMYD3, was added to columns 11, 12, 23, 24, rows I-P for the minimum signal control. A cocktail (40 ul) containing the SMYD3 enzyme was added by Multidrop Combi (Thermo-Fisher). The compounds were allowed to incubate with SMYD3 for 30 min at room temperature, then a cocktail (10 ul) containing SAM and MEKK2 was added to initiate the reaction (final volume=51 ul). The final concentrations of the components were as follows: SMYD3 was 0.4 nM, 3H-SAM was 8 nM, MEKK2 was 12 nM, SAH in the minimum signal control wells was 1 mM, and the DMSO concentration was 2%. The assays were stopped by the addition of non-radiolabeled SAM (10 ul) to a final concentration of 100 uM, which dilutes the 3H-SAM to a level where its incorporation into MEKK2 is no longer detectable. Radiolabeled MEKK2 was detected using a scintillation proximity assay (SPA). 10 uL of a 10 mg/mL solution of SPA beads in 0.5 M citric acid was added and the plates centrifuged at 600 rpm for 1 min to precipitate the radiolabeled MEKK2 onto the SPA beads. The plates were then read in a PerkinElmer TopCount plate reader to measure the quantity of 3H-labeled MEKK2 as disintegrations per minute (dpm) or alternatively, referred to as counts per minute (cpm).

Assay: Inhibition Assay: Class I PI3-Ks can be either purchased (p110α/p85α, p110β/p85α, p110δ/p85α from Upstate, and p110γ from Sigma) or expressed as previously described (Knight et al., 2004). IC50 values are measured using either a standard TLC assay for lipid kinase activity (described below) or a high-throughput membrane capture assay. Kinase reactions are performed by preparing a reaction mixture containing kinase, inhibitor (2% DMSO final concentration), buffer (25 mM HEPES, pH 7.4, 10 mM MgCl2), and freshly sonicated phosphatidylinositol (100 μg/ml). Reactions are initiated by the addition of ATP containing 10 μCi of γ-32P-ATP to a final concentration 10 or 100 μM and allowed to proceed for 5 minutes at room temperature. For TLC analysis, reactions are then terminated by the addition of 105 l 1N HCl followed by 160 μl CHCl3:MeOH (1:1). The biphasic mixture is vortexed, briefly centrifuged, and the organic phase is transferred to a new tube using a gel loading pipette tip precoated with CHCl3. This extract is spotted on TLC plates and developed for 3-4 hours in a 65:35 solution of n-propanol:1M acetic acid. The TLC plates are then dried, exposed to a phosphorimager screen (Storm, Amersham), and quantitated. For each compound, kinase activity is measured at 10-12 inhibitor concentrations representing two-fold dilutions from the highest concentration tested (typically, 200 μM). For compounds showing significant activity, IC50 determinations are repeated two to four times, and the reported value is the average of these independent measurements.

Assay: PDK1 kinase assay: PDK1 (amino acids 51-359) and AKT2 (amino acids 140-467 fused to PIFtide, amino acids EEQEMFRDFDYIADW) were expressed as N-terminally tagged GST fusion proteins in insect cells and purified to homogeneity. Enzyme activity was determined in a coupled PDK1/AKT/FAM-crosstide assay and phosphorylation of FAM-crosstide was determined by standard IMAP protocol (Molecular Devices). For inhibition studies, compounds were titrated 4-fold in DMSO and diluted 40-fold into assay buffer (10 mM Tris HCl pH7.2; 10 mM MgCl2; 0.01% Triton X-100; 1 mM DTT) containing PDK1, AKT2, and FAM-crosstide (final concentrations: 0.75 nM PDK1, 10 nM unphosphorylated AKT2, and 100 nM crosstide substrate). The kinase reaction was initiated by adding ATP to a final concentration of 40 μM of PDK1 and incubated at 25° C. for 30 min. To detect assay product, the kinase reaction was combined with Progressive Binding Solution (1:600 Progressive Binding Reagent, 50% Buffer A, 50% Buffer B, Molecular Devices) in a 1:3 ratio. The mixture was incubated for 2 hours at 25° C. and the plate was scanned on an Analyst AD with excitation at 485 nm and emission at 530 nm. The fluorescence polarization value P is defined by the equation below. The value mP is generated by multiplying the P value for each reaction well by a factor of 1000. The value ΔmP for each well is the mP value for that well minus the mP value for the average negative control. P=(Fpar−Fperp)/(Fpar+Fperp)  Eq.:Where par is fluorescence intensity parallel to the excitation plane; and perp is fluorescence intensity perpendicular to the excitation plane. ΔmP values were plotted as a function of compound concentration and the data were analyzed with a 4-parameter fit using GraphPad Prism software.

Briefly, N-terminal GST tagged recombinant human RET cytoplasmic domain (aa 658-end) from Eurofins (0.25 nM RET; Catalog No. 14-570M) or N-terminal GST tagged recombinant human V804M mutant RET cytoplasmic domain (aa 658-end) from Millipore (0.25 nM enzyme; Catalog No. 14-760) was incubated with 250 nM TK-substrate biotin (CisBio, part of Catalog No. 62TK0PEC) and 1 mM ATP along with test compound in a buffer consisting of 25 mM HEPES pH 7.4, 10 mM MgCl2, 0.01% Triton X-100, and 2% DMSO in a volume of 8 μL. Compounds were typically prepared in a threefold serial dilution in DMSO and added to the assay to give the appropriate final concentration. After a 30-minute incubation at 22° C., the reaction was quenched by adding 8 μL of quench solution containing 31.25 nM Sa-XL665 and 1×TK-ab-Cryptate in HTRF detection buffer (all from CisBio, part of Cat. No. 62TK0PEC). After a 1 hour incubation at 22° C., the extent of reaction was determined using a PerkinElmer EnVision multimode plate reader via HTRF dual wavelength detection, and the percent of control (POC) was calculated using a ratiometric emission factor. 100 POC was determined using no test compounds and 0 POC was determined using pre-quenched control reactions. The POC values were fit to a 4 parameter logistic curve, and the IC50 is defined as the concentration of inhibitor at which the POC equals 50 for the fitted curve.
Measurement: IC50 = 340 nM (pChEMBL 6.46999979019165)
