Target: Nuclear receptor ROR-gamma (SINGLE PROTEIN), Homo sapiens
UniProt: P51449
Assay: GAL4-RORgamma Transactivation: The RORγ transactivation model was developed from the line HG5LN, which is a HeLa line that stably expresses a luciferase reporter gene controlled by a pentamer of the GAL4 recognition domain of yeast and of a β-globin promoter. The HG5LN line was stably transfected by the DNA-binding domain (DBD) of GAL4 fused to the ROR gamma ligand-binding domain (LBD). Molecules that inhibit the ROR gamma constitutive activity reduce the luciferase expression, thus leading to a reduction in the emitted luminescence.The cells are seeded in 384-well plates (5000 cells in 45 μL/well of culture medium containing 10% fetal calf serum) and incubated for 4 hours at 37° C., 5% CO2. 5 μL of the test molecules (compounds described in the tables described above) are then added to each well and the plates are incubated for 18 hours at a temperature of 37° C. under 5% of CO2. 20 μL of luciferase substrate (Promega) are added to each well and the luminescence emitted is read by a microplate reader.The luminescence units (RLU) are normalized by positive controls (POS containing a saturated concentration of benzenesulfonamide, N-(2,2,2-trifluoroethyl)-N-[4-[2,2,2-trifluoro-1-hydroxy-1-(trifluoromethyl)ethyl]phenyl]) and negative controls (NEG containing DMSO): % inhibition=((RLU−NEG)*100)/(POS−NEG). The IC50 values are calculated from a 4-parameter logistic model using the XLFit software (IDBS).

Assay: Kinase Assay: The DYRK1A kinase assay was run using the Ser/Thr 18 peptide Z-lyte assay kit according to manufacturer's instructions (Life Technologiesa Division of Thermo-Fisher). This is a non-radioactive assay using fluorescence resonance energy transfer (FRET) between coumarin and fluorescein to detect kinase activity which is represented as a ratio of coumarin emission/fluorescein emission.Briefly, recombinant DYRK1A kinase, ATP and Ser/Thr peptide 18 were prepared in 1× Kinase buffer to final concentrations of 0.19 μg/mL, 30 μM, and 4 μM respectively. The mixture was allowed to incubate with the representative compounds for one hour at room temperature. All reactions were performed in duplicate. Unphosphorylated ("0% Control") and phosphorylated ("100% control") forms of Ser/Thr 18 served as control reactions. Additionally, an 11-point dose-response curve of Staurosporine (luM top) was run to serve as a positive compound control.

Assay: In Vitro Assay: Human orexin-A as an agonist is prepared as 1 mM stock solution in MeOH: water (1:1), diluted in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES for use in the assay at a final concentration of 3 nM.Antagonists are prepared as 10 mM stock solution in DMSO, then diluted in 384-well plates using DMSO followed by a transfer of the dilutions into in HBSS containing 0.1% bovine serum albumin (BSA), NaHCO3: 0.375 g/L and 20 mM HEPES. On the day of the assay, 50 uL of staining buffer (HBSS containing 1% FCS, 20 mM HEPES, NaHCO3: 0.375 g/L, 5 mM probenecid (Sigma) and 3 uM of the fluorescent calcium indicator fluo-4 AM (1 mM stock solution in DMSO, containing 10% pluronic) is added to each well. The 384-well cell-plates are incubated for 50 min at 37° C. in 5% CO2 followed by equilibration at rt for 30 min before measurement.Within the Fluorescent Imaging Plate Reader (FLIPR Tetra, Molecular Devices), antagonists are added to the plate in a volume of 10 uL/well, incubated for 120 min and finally 10 uL/well of agonist is added. Fluorescence is measured for each well at 1 second intervals, and the height of each fluorescence peak is compared to the height of the fluorescence peak induced by 3 nM orexin-A with vehicle in place of antagonist. The IC50 value (the concentration of compound needed to inhibit 50% of the agonistic response) is determined and may be normalized using the obtained IC50 value of an on-plate reference compound. Optimized conditions were achieved by adjustment of pipetting speed and cell splitting regime. The calculated IC50 values may fluctuate depending on the daily cellular assay performance. Fluctuations of this kind are known to those skilled in the art. In the case where IC50 values have been determined several times for the same compound, the geometric mean has been given.

Target: Proto-oncogene Wnt-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P04628
Assay: The screening assay for Wnt activity: The screening assay for Wnt activity is described as follows. Reporter cell lines can be generated by stably transducing cancer cell lines (e.g., colon cancer) or primary cells (e.g., IEC-6 intestinal cells) with a lentiviral construct that includes a Wnt-responsive promoter driving expression of the firefly luciferase gene.SW480 colon carcinoma cells were transduced with a lentiviral vector expressing luciferase with a human Sp5 promoter consisting of a sequence of eight TCF/LEF binding sites. SW480 cells stably expressing the Sp5-Luc reporter gene and a hygromycin resistance gene were selected by treatment with 150 μg/ml of hygromycin for 7 days. These stably transduced SW480 cells were expanded in cell culture and used for all further screening activities. For Sp5-Luc reporter gene assays, the cells were plated at 10,000 cells/well in 96-well plates with growth medium containing 10% fetal calf serum and incubated overnight at 37° C. and 5% CO2. Each compound was dissolved in DMSO as a 10 mM stock in standard j-vials and used to prepare compound source plates in dose-response format with 3-fold serial dilutions and a 10 mM top concentration. Compound transfer from serially diluted source plates to assay plates containing the cells was accomplished using a pintool (Multimek 96, Beckman equipped with V&P Scientific FP1S50H pins) based liquid handling protocol. This protocol used a slotted pin to transfer 50 nl of compound from a source plate well to an assay plate well containing 50 μl of cells in growth medium. The 1000-fold dilution resulted in a final DMSO concentration of 0.1% on the cells in each well. Control wells received 50 nl of DMSO treatment for normalization and calculating IC50 values. The treated cells were incubated at 37° C. and 5% CO2 for an additional forty-two hours. Following incubation, the growth medium was removed and 50 μl of BrightGlo luminescence reagent (Promega) was added to each well of the 96-well assay plates. The plates were placed on an orbital shaker for 5 min and then luminescence was quantified on the Victor3 (Perkin Elmer) plate reader. Readings were normalized to DMSO only treated cells, and normalized activities were utilized for IC50 calculations using the dose-response log (inhibitor) vs. response-variable slope (four parameters) nonlinear regression feature available in GraphPad Prism 5.0 or 6.0.

Assay: Biological Activity: Endothelial lipase (EL) and hepatic lipase (HL) activities were measured using a fluorescent substrate, A10070, (Invitrogen, CA) doped into an artificial vesicle containing DMPG (Avanti Polar Lipids) as the excipient. Vesicles were prepared by combining 571 μL of 29 mM DMPG in a 1:1 mixture of MeOH and CHCl3 with 2000 μL of 1 mM A10070 in a 1:1 mixture of MeOH and CHCl3. The mixture was dried under nitrogen in multiple vials then resuspended in 20 mL total volume of 50 mM HEPES pH 8.0 buffer containing 50 mM NaCl and 0.2 mM EDTA. The sample was allowed to sit at room temperature for 15 min and then was sonicated 3×4 mins on ice with a Branson Sonicator using duty cycle 1. This preparation provides vesicles with a mole fraction of 0.11 for the FRET substrate.The enzymatic assay was measured using 384-well white Optiplates. Each well contained 20 μL of assay buffer (50 mM HEPES pH 8.0, 50 mM NaCl and 1 mM CaCl2) and 0.25 μL of a DMSO solution containing a compound of interest. EL or HL (10 μL) was added and allowed to incubate with the compound for 30 min at 37° C. The source of EL was conditioned media obtained from HT-1080 cells that were transformed using RAGE technology (Athersys) to overexpress endogenous EL, and HL was partially purified from conditioned media obtained from COS cells overexpressing HL. The reaction was started by the addition of 10 μL of a 1:10 dilution of vesicles. The final total reaction volume was 20.25 μL. The reaction rates were measured on a Gemini plate reader with an excitation wavelength of 490 nm and an emission wavelength of 530 nm. Readings were taken over a period of 60 minutes, and the slope between 300 and 900 secs of the readout was used to calculate the rate of the reaction.

Assay: transient human FXR/Gal4-luciferase reporter assay: A Gal4-hFXR fusion construct reporter system was used as the primary assay to characterize compound activity. A construct including 5 copies of the Gal4 promoter response element upstream of a firefly luciferase reporter cDNA was stably expressed in HEK293 cells. This reporter cell line was maintained in Dulbecco's Modified Eagle's medium (DMEM; Gibco) supplemented with 1% penicillin-streptomycin (P/S) solution, 500 μg/mL Zeocin and 10% charcoal/dextran-treated fetal bovine serum (cs-FBS) at 37° C. in a humidified 5% CO2 atmosphere. Another plasmid was constructed in which the human cytomegalovirus promoter in the pcDNA3.1 vector directs the expression of the cDNA encoding a fusion protein comprised of the DNA binding domain from the Gal4 transcription factor fused to the ligand binding domain from human FXR.The day prior to transfection, the reporter cells in culture are detached from the plate with trypsin and plated into a T75 flask at a sufficient density to achieve approximately 90% confluence the next morning. The transfection reagents are prepared by separately diluting 25 μg of the pcDNA3.1-Gal4-FXR plasmid into 1.87 mL of Opti-MEM (Thermo-Fisher), and 40 μL of Lipofectamine 2000 (Thermo-Fisher) into 1.87 mL of Opti-MEM, and then adding the diluted DNA solution into the diluted Lipofectamine 2000 solution and incubating at room temperature for 15-20 minutes. The mixture is further diluted with 10 mL of a solution comprised of DMEM, 10% cs-FBS, and 1% P/S immediately prior to transferring to the cells. The maintenance culture media is aspirated from the cells and the final transfection mixture is added before the cells are incubated overnight at 37° C. in a humidified 5% CO2 atmosphere. This protocol can be scaled up, and the transiently transfected cells can be cryopreserved in an assay-ready format.For compound testing, 100 nL of the compounds (serial dilutions in DMSO) are dispensed with an Echo acoustic dispenser (Labcyte) into the wells of a Corning/Costar clear bottom 384-well white plate. The transfected cells are harvested, counted, and diluted such that 10-25,000 cells in 25 μL are plated into each well of the 384-well compound assay plate. The compound-treated cells are incubated overnight at 37° C. in a humidified 5% CO2 atmosphere. The next morning 25 μL of Steady-Glo (Promega) are added to each well of the plate, the mixture is incubated for 15 min. with shaking, and luminescence is measured on an Envision (Perkin Elmer) plate reader. Background counts from cells treated with DMSO alone are subtracted from all raw counts, and the corrected values are converted to a percentage of the control response attained with 8 μM GW-4064. These data are fit to a 4-parameter log agonist-response equation to calculate an EC50 value.

Assay: Biochemical Assay: Assays for biochemical cell-based activity of c-kit kinase are known in the art, for example, as described in U.S. Pat. Nos. 7,498,342 and 7,846,941, the disclosures of which are hereby incorporated by reference as it relates to such assays. The c-kit (or kinase domain thereof) is an active kinase in AlphaScreen. IC50 values are determined with respect to inhibition of c-Kit kinase activity, where inhibition of phosphorylation of a peptide substrate is measured as a function of compound concentration. Compounds to be tested were dissolved in DMSO to a concentration of 30 mM. These were diluted 30 μl into 130 μl of DMSO (4 mM) and 1 μl was added to an assay plate. These were then serially diluted 1:3 (50 μl to 100 μl DMSO) for a total of 8 points. Plates were prepared such that each kinase reaction is 30 μl in 1× kinase buffer (50 mM HEPES, pH 7.2, 5 mM MgCl2, 5 mM MnCl2, 0.01% NP-40, 0.2% BSA), 5% DMSO and 10 μM ATP. Substrate was 100 nM biotin-(E4Y)3 (Open Source Biotech, Inc.). C-kit kinase was at 0.1 ng per sample. After incubation of the kinase reaction for 1 hour at room temperature, 5 μl of donor beads (Streptavidin coated beads (Perkin Elmer Life Science) final concentration 1 μg/ml) in stop buffer (50 mM EDTA in 1× kinase buffer) was added, the sample was mixed and incubated for 30 minutes at room temperature before adding 5 ml of acceptor beads (PY30 coated beads (Perkin Elmer Life Science) final concentration 1 μg/ml) in stop buffer. The samples were incubated for 60 minutes at room temperature and the signal per well was read on AlphaQuest reader. Phosphorylated substrate results in binding of the PY30 antibody and association of the donor and acceptor beads such that signal correlates with kinase activity.

Assay: Enzymatic Reaction Assay: The NAMPT enzymatic reactions were carried out in Buffer A (50 mM Hepes pH 7.5, 50 mM NaCl, 5 mM MgCl2, and 1 mM THP) in 96-well V-bottom plates. The compound titrations were performed in a separate dilution plate by serially diluting the compounds in DMSO to make a 100× stock. Buffer A (89 μL) containing 33 nM of NAMPT protein was added to 1 μL of 100× compound plate containing controls (e.g. DMSO or blank). The compound and enzyme mixture was incubated for 15 min at rt, then 10 μL of 10× substrate and co-factors in Buffer A were added to the test well to make a final concentration of 1 μM NAM, 100 μM 5-Phospho-D-ribose 1-diphosphate (PRPP), and 2.5 mM Adenosine 5′-triphosphate (ATP). The reaction was allowed to proceed for 30 min at rt, then was quenched with the addition of 11 μL of a solution of formic acid and L-Cystathionine to make a final concentration of 1% formic acid and 10 μM L-Cystathionine. Background and signal strength was determined by addition (or non-addition) of a serial dilution of NMN to a pre-quenched enzyme and cofactor mix.

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.

Target: Catenin beta-1/Protein Wnt-3a (PROTEIN COMPLEX), Homo sapiens
UniProt: P56704
Assay: Evaluation of Biological Activity: Compounds that enhance the Wnt activity, or Activators, were assayed as follows. Reporter cell lines were generated by stably transducing cells of colon cancer cell lines (with a lentiviral construct that included a Wnt-responsive promoter driving expression of the firefly luciferase gene).Lentiviral constructs were made in which the SP5 promoter, a promoter having eight TCF/LEF binding sites derived from the SP5 promoter, was linked upstream of the firefly luciferase gene. The lentiviral constructs also included a hygromycin resistance gene as a selectable marker. The SP5 promoter construct was used to transduce SW480 cells, a colon cancer cell line having a mutated APC gene that generates a truncated APC protein, leading to de-regulated accumulation of β-catenin.Cultured SW480 cells bearing a reporter construct were distributed at approximately 10,000 cells per well into 384- or 96-well multiwell plates. Compounds from a small molecule compound library were then added to the wells in half-log dilutions using a maximum concentration of three or ten micromolar. A series of control wells for each cell type received only buffer and compound solvent DMSO. Twenty-four hours after the addition of compound, reporter activity for luciferase was assayed, for example, by addition of the BrightGlo luminescence reagent (Promega) and the Victor3 plate reader (Perkin Elmer). Readings were normalized to DMSO only treated cells, and any activities above DMSO were considered activation. Compounds were considered activators if reporter activities were 2× fold or greater than DMSO. EC50 is the concentration at half maximal activation.

Assay: TLR7/8/9 Inhibition Reporter Assays: HEK-Blue-cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors were used for screening inhibitors of these receptors using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of the IFN-β minimal promoter fused to five NF-κc Band AP-1-binding sites. Briefly, cells are seeded into Greiner 384 well plates (15000 cells per well for TLR7, 20,000 for TLR8 and 25,000 for TLR9) and then treated with test compounds in DMSO to yield a final dose response concentration range of 0.05 nM-50 μM. After a 30 minute compound pre-treatment at room temperature, the cells are then stimulated with a TLR7 ligand (gardiquimod at a final concentration of 7.5 μM), TLR8 ligand (R848 at a final concentration of 15.9 μM) or TLR9 ligand (ODN2006 at final concentration of 5 nM) to activate NF-κB and AP-1 which induce the production of SEAP. After a 22 hour incubation at 37° C., 5% CO2, SEAP levels are determined with the addition of HEK-Bue Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications. The percent inhibition is determined as the % reduction in the HEK-Blue signal present in wells treated with agonist plus DMSO alone compared to wells treated with a known inhibitor.

Assay: GLS Enzyme Potency Assay: A Glutamate Oxidase/AmplexRed coupled assay was used to measure the ability of compounds to bind to and inhibit the activity of GLS1 in vitro. 6His tagged GLS protein (amino acids 63-669) expressed in E. Coli was purified and stored at −80° C. in aliquots. GLS1 was diluted to 2× working concentration and incubated at r.t. to allow the tetrameric/dimeric forms to reach steady state. Assay measurements were performed in buffer comprising 50 mM TRIS pH 7.8, 100 mM NaPO4, pH 7.8, 0.001% v/v Tween20. Purified recombinant GLS1 protein was diluted in assay buffer to 12 nM and pre-incubated at r.t. for 30 minutes. Test compounds were prepared by dilution in 100% DMSO to give the correct dose range for 12 point concentration response and an appropriate volume (2.5-60 nl) dispensed into 384 well micro assay plates (Greiner product code 784900) using a Labcyte Echo 555 acoustic dispenser. DMSO concentration was maintained at 2% by back filling with DMSO solution. 3 μL of diluted GLS1 protein (12 nM) was then dispensed into each well using a BioRaptr automated dispenser (Beckman-Coulter) and incubated for 15 minutes at r.t. 3 μL of 100 mM glutamine diluted in assay buffer was then added and the reaction incubated at r.t. for 60 minutes. The reaction was then stopped by addition of 45 μM 6-(2-bromoethynyl)-2,3-dimethyl-quinazolin-4-one, 75 μM Amplex Red, 0.375 units/mL Horseradish Peroxidase, 0.12 units/mL Glutamate Oxidase in 100 mM TRIS pH7.5. After 30 minutes at room temp in the dark, plates were read on a Perkin Elmer EnVision using 535/590 nm optic filters and raw data analysed using Genedata to generate IC50 values. An artefact version of the assay where the 6His tagged GLS protein and glutamine were replaced with assay buffer was also used to rule out non specific effects on the assay components.
