Target: Toll-like receptor 9 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NR96
Assay: Inhibition Reporter Assay: 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-κB and 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 a 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-Blue Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications.

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: Intracellular Calcium Measurement to Assess Antagonist Activity at Human P2X3 and Human P2X2/3 Receptors: A fluorescent imaging plate reader (FLEX/FLIPR station; Molecular Devices) was used to monitor intracellular calcium levels using the calcium-chelating dye Fluo-4 (Molecular Probes). The excitation and emission wavelengths used to monitor fluorescence were 470-495 nm and 515-575 nm, respectively. Cells expressing purinergic receptors P2X3 (human) or P2X2/3 (human) were plated at a density of 15,000 cells/well in collagen-coated 384-well plates approximately 20 hours before beginning the assay. On the day of the assay, 20 μl of loading buffer (Hank's balanced salt solution, 20 mM HEPES, 0.5 mM CaCl2, 0.5 mM MgCl2, 0.1% BSA, 5 mM probenecid, 10 mM D-glucose monohydrate, 2 μM Fluo-4, and 5 units/mL, hexokinase, pH=7.4) was added and cells dye-loaded for 90 min at 37° C. The dye supernatant was removed and replaced with 45 μl probenecid buffer (Hank's balanced salt solution, 20 mM HEPES, 0.5 mM CaCl2, 0.5 mM MgCl2, 0.1% BSA, 5 mM probenecid, 10 mM D-glucose monohydrate, pH=7.4). The test compound was added in a volume of 5 μl and allowed to incubate for 30 min at 37° C. The final assay DMSO concentration is 1%. The agonist, α,β-Me-ATP, was added in a volume of 20 μl at a concentration representing the EC80 value. The fluorescence was measured for an interval of 90 sec at 2 sec intervals and analyzed based on the increase in peak relative fluorescence units (RFU) compared to the basal fluorescence. Peak fluorescence was used to determine the response to agonist obtained at each concentration of test compound by the following equation: % Response=100*(RFU(test compound)−RFU(control))/(RFU(DMSO)−RFU(control))The Examples were tested in triplicates per plate and mean values were plotted in Excel XLFit to determine IC50 values at the human P2X3 and human P2X2/3 receptors, percentage of maximal inhibition and the Hill coefficients.

The IC50 values were derived by fitting the data to the equation for a sigmoidal dose-response with a variable slope. Y=Bottom+(Top−Bottom)/(1+10^((Log IC50−X)*HillSlope)) where X is the logarithm of concentration and Y is the response. Compounds having an IC50 of 1 μM or less are considered active. The compounds of the invention were found to be selective inhibitors of FGFR3 and/or FGFR4 according to the FGFR Enzymatic Assays. Compounds of Formula (I′) and (I) and all the compounds as described herein have been tested and exhibit an IC50 of less than 1 μM. Table 1 provides IC50 data for compounds of the invention assayed in the FGFR Enzymatic Assay after dilution in assay buffer, added to the plate and pre-incubated for 4 hours.

Target: Fatty-acid amide hydrolase 1 (SINGLE PROTEIN), Homo sapiens
UniProt: O00519
Assay: FAAH Assay: All reagents were purchased from Sigma-Aldrich unless specified. Human and Rat Fatty Acid Amide Hydrolase (FAAH) genes used in assay have been described by Patricelli et al. (Biochemistry. 1998, 37(43), 15177-87). The transmembrane domain-deleted Fatty Acid Amide Hydrolase (FAAH) genes were cloned into pET15b (Novagen, #69661) (human FAAH)/pET 28a (Novagen, #69864-3) (rat FAAH gene) plasmids and expressed in E coli BL21 DE3. Chaperone protein groEL-groES in pGRO7 plasmid (Takara Bio Inc, Japan) was co-expressed with Fatty Acid Amide Hydrolase (FAAH) to improve solubility of the protein expressed in E coli. The protein was expressed and enriched as described in Mileni et al. (Proc Natl Acad Sci USA. 2008, 105(35),12820-4). Briefly, the bacterial cultures in Luria Broth (2 L) were induced with arabinose (2 mM) and Isopropyl (β-D-1-thiogalactopyranoside, IPTG (1 mM), for 20 h at room temperature. The cultures were centrifuged at 1200×g for 10 min and the cell pellet was resuspended in 100 mL buffer containing of 20 mM NaPi (pH 7.4), 100 mM NaCl, Benzonase (500u), Aprotinin (1 μg/mL) and Leupeptin (1 μg/mL). Cells were lyzed by sonication (Amp 20%, Pulse 15 s×15, on ice) and the cell debris removed by centrifugation at 5000×g for 20 min. The supernatant was enriched via ultracentrifugation at 100,000×g for 1 h and the cell pellet was resuspended in 16 mL buffer containing 20 mM NaPi (pH 7.8), 500 mM NaCl, 1% Triton X-100. The resuspended cell extract was subjected to ultra-centrifugation at 100,000×g for 1 h and the enriched supernatant was used in the in vitro assay. All protein extraction steps were carried out on ice or at 4° C.
