Assay: RET Enzyme Assay: The potency of compounds inhibiting several different RET kinase forms (Wild Type, V804M, M918T, G810R, & G810S) were determined using CisBio's HTRF Kinease-TK assay technology. The kinases were incubated with 250 nM TK-substrate biotin (CisBio, part of cat #62TK0PEC) at Km ATP along with test compounds 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 as a three-fold serial dilution in DMSO and added to the assay to give the appropriate final concentration. After a 30-min 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 #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. One hundred POC was determined using DMSO only samples (no compound present), and 0 POC was determined using pre-quenched control reactions. A 4-parameter logistic curve was fit to the POC values as a function of the concentration of compound, and the IC50 value was the point where the best-fit curve crossed 50 POC.

Target: Orexin receptor type 2 (SINGLE PROTEIN), Homo sapiens
UniProt: O43614
Assay: Human Orexin 2 Receptor Radioligand Binding Assay: HEK293 stably expressing human orexin 2 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1× Pen/Strep, 1× NaPyruvate, 10 mM HEPES, 600 ug/ml G418 media on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1× with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2K×G, 5 min at 40° C.), the supernatant was aspirated and the pellets frozen and stored at −800° C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec just prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-EMPA (Moraveck Corporation, specific activity=29.6 Ci/mmol), diluted to a 5 nM concentration in PBS (2 nM final concentration). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentration (from 0.1 nM to 10 μM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 μM almorexant. The total volume of each reaction is 200 μL (20 μL of diluted compounds, 80 μL of [3H]-EMPA diluted in PBS and 100 μL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Target: Toll-like receptor 9 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9NR96
Assay: TLR7/8/9 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. 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.

Target: Tyrosine-protein kinase JAK3 (SINGLE PROTEIN), Homo sapiens
UniProt: P52333
Assay: Biochemical JAK Assay: 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 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 lh. 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 lh 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.Test compounds having a higher pKi value in each of the four JAK assays show greater inhibition of JAK activity. Compounds of the invention tested in this assay typically exhibited pKi values between about 7 and about 10.3

Assay: Human LXRalpha and LXRbeta Coactivator Recruitment FRET Assay: This assay is based on the ability of the LXR-LBDs (LXRα and LXRβ) to recruit and interact with a co-activator peptide. This assay was run in agonist mode, to characterize compounds of the invention that exhibit LXR agonist activity, and in antagonist mode to characterize compounds of the invention having LXR antagonist activity and which cause a concentration-dependent release of the co-activator peptide in the presence of the full LXR agonist T0901317. The interaction between glutathione S-transferase (GST)-tagged, recombinant human LXRα-LBD or LXRβ-LBD and fluorescein-conjugated co-activator peptide SRC2-3 (Cat# PV4588, Life Technologies, Grand Island, N.Y.) was measured via time resolved-fluorescence resonance energy transfer (TR-FRET). The assay was performed in 96-well half-area black Opti-plates (Cat# 3686, Corning, Lowell, Mass.) in 20 mM TRIS-HCl buffer, pH 8, containing 150 mM NaCl and 5 mM DDT in a total volume of 80 μL. Test compounds were dissolved in DMSO, and semi-log (3.162×) serial dilutions were also prepared in DMSO, as 40× solutions.

Assay: ADPGlo Assay: The assays were performed in 384-well, low volume microtiter assay plates in a final reaction volume of 6 ul. Dose-response curves were generated by incubating 10 nM of each kinase in 50 mM Hepes pH 7.5, 0.02% Tween 20, 0.02% BSA, 1 mM DTT, 10 μm Na3VO4, 10 mM β-Glycerolphosphate, 1 mM MgCl2, 12 mM MnCl2 and 15 μm ATP for 60 min at 32° C. in the presence or absence of compound diluted in DMSO. The amount of generated ADP is a measure of kinase activity and is quantified using the ADP-Glo™ Kinase Assay (Promega) according to manufacturer's instructions. ADP is converted to ATP by adding 3 ul of ADP-Glo™ Reagent and incubation at 32° C. for 60 min. ATP is subsequently converted into a bioluminescent signal by adding 6 ul luciferase assay reagents (Kinase detection buffer+Kinase Detection Substrate (Promega)) and further incubation at 32° C. for 60 min. For the measurement of luminescence a PHERAstar™ Multilabel Reader was used at a measurement interval time of 0.1 second (optical module for luminescence measurements in the 230 nm to 750 nm wavelength range).

Assay: OPR Mu Antagonist Assay: The purpose of this assay is to confirm the potency and selectivity of compounds synthesized to be OPRK1 Antagonists. This assay monitors the OPRMu1 activation, in membrane recruitment of β-arrestin. The assay monitors GPCR-β-arrestin proximity using low affinity fragment complementation of beta-galactosidase (beta-gal). It employs U20S cells which express OPRMu1 fused to the complementary beta-gal fragment (enzyme acceptor). As designed, compounds that act as antagonists will prevent receptor activation resulting in reduce well luminescence. Compounds were tested in triplicate using a 10-point, 1:3 dilution series starting at a nominal concentration of 10 micromolar.The Discover X OPRMu1-U20S cell line was routinely cultured in T175 flasks at 37° C., 5% CO2 and 95% relative humidity (RH). The growth media consisted of DMEM/F12 1:1 Media supplemented with 10% v/v heat inactivated fetal bovine serum, 25 mM HEPES, Non-essential amino acids, 1 mM Sodium Pyruvate, 1× antibiotic mix (penicillin streptomycin) plus 500 ug/mL Geneticin and 300 ug/mL Hygromycin (selection antibiotics).On Day 1 of the assay, 5000 cells in 20 ul of assay buffer (Discover X's Cell Plating Reagent 5) were seeded into each well of a 384 Corning 3570 standard white plate, and incubated 16-24 hours at 37° C., 5% CO2 and 95% (RH). On Day 2, 100 nl of test compound in DMSO was added to the appropriate wells, 100 nl of DMSO added to control wells and plates were incubated for 30 min at 37° C., 5% CO2 and 95% (RH). Next 100 nl of DAMGO OPRMu1 or DMSO in assay media (EC80 Challenge consists of 100 nl of 50 uM DAMGO, final assay concentration=250 nM, 100% Response wells receive 100 nl 200 uM DAMGO). After incubation for 3 hours at 37° C., 5% CO2 and 95% (RH), 10 ul of Path Hunter Detection Mix is added to each well, plate placed on a plate rotator/mixer for 10 minutes and then incubated at room temperature, in the dark for 1 hour. Well luminescence was measured on Perkin Elmer's Envision.The Percent Inhibition was calculated from the median ratio as follows:% ⁢ ⁢ Inhibition = 100 - ( 1 ⁢ 0 ⁢ 0 ⁢ ( Compound ⁢ ⁢ Well - 0 ⁢ % ⁢ ⁢ Response ⁢ ⁢ Well EC ⁢ ⁢ 80 ⁢ ⁢ Control ⁢ ⁢ Well - 0 ⁢ % ⁢ ⁢ Response ⁢ ⁢ Well ) )where:    COMPOUND WELL is defined as the well containing test compound;    EC80 CONTROL WELL is defined as wells containing DAMGO challenge (250 nM final)=0% inhibition; and    0% RESPONSE WELL is defined as wells containing DMSO=100% inhibition.IC50 is defined as the concentration of compound required to achieve 50% inhibition.

Assay: Biochemical JAK Assay: 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 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 lh. 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 lh 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.Test compounds having a higher pKi value in each of the four JAK assays show greater inhibition of JAK activity. Compounds of the invention tested in this assay typically exhibited pKi values between about 7 and about 10.3

Assay: Patch Clamp Assay: The patch-clamp measurement was carried out at room temperature in whole-cell configuration on human embryonic kidney cells (HEK293) which have been transfected in a stable manner with the hERG gene.The whole-cell configurations were carried out using an automated patch clamp device (Patchliner, Nanion Technologies, Munich). This is a glass chip-based system with which automated whole-cell measurements on up to 8 cells simultaneously are possible. The glass chip has a hole of defined size to which the cell is transferred into the Gigaseal by application of a reduced pressure and brought into the whole-cell configuration. Buffer, cell suspension and test substances were added to microchannels of the chip using a Teflon-coated pipette. The cells were clamped to a holding potential of -80 mV. For measurement of substance-promoted inhibition of the Kv11.1 channel, the following voltage protocol was applied at 10-second intervals: 51 ms/-80 mV, 500 ms/+40 mV, 500 ms/-40 mV, 200 ms/-80 mV. The leakage current is subtracted by means of the P4 method. The cells were resuspended in extracellular buffer (EC) and applied to the chip. After the cell had been collected, the seal was improved by addition of a seal enhancer buffer. As soon as the whole-cell configuration had been reached, the seal enhancer buffer was washed out and replaced by extracellular buffer. The measurement started in EC for 1.5 min. DMSO (vehicle control, 0.1% of DMSO) was then applied, and the control current was recorded for 3 min. The test substance was subsequently added twice in the same concentration, and the potassium current was measured for 3.5 min in each case.

Assay: In Vitro DGK Inhibition Assay: The reactions were carried out in 50 mM MOPS pH 7.5, 100 mM NaCl, 10 mM MgCl2, 1 μM CaCl2, and 1 mM DTT (assay buffer). The reactions using a detergent/lipid micelle substrate also contained 50 mM octyl B-D-glucopyranoside. The lipid substrate concentrations were 11 mM PS and 1 mM DAG for the detergent/lipid micelle reactions. The lipid substrate concentrations were 2 mM PS, 0.25 mM DAG, and 2.75 mM PC for the extruded liposome reactions (5 mM total lipid). The reactions were carried out in 150 μM ATP. The enzyme concentrations for the DGKα and DGKζ were 5 nM. The compound inhibition studies were carried out as follows: 25 nL (ADPGLO assay) or 50 nL (LIPGLO assay) droplets of each test compound (top concentration 10 mM with 11 point, 3-fold dilution series for each compound) solubilized in DMSO were transferred to wells of a white 1536 well plate (Corning 3725). A 5 mL enzyme/lipid substrate solution at 2× final reaction concentration was prepared by combining 2.5 mL 4× enzyme solution (20 nM DGKα or DGKζ (prepared as described below) in assay buffer) and 2.5 mL of either 4× liposome or 4× detergent/lipid micelle solution (compositions described below) and incubated at room temperature for 10 minutes. Next, 1 μL 2× enzyme/lipid substrate solution was added to wells containing the test compound and reactions were initiated with the addition of 1 μL 300 uM ATP. The reactions were allowed to proceed for 2 hr (ADPGLO assay) or 1 hr (LIPGLO assay), after which 2 μL Glo Reagent (Promega V9101) was added and incubated for 40 minutes. Next, 4 μL Kinase Detection Reagent was added and incubated for 30 minutes. Luminescence was recorded using an EnVision microplate reader. The percent inhibition was calculated from the ATP conversion generated by no enzyme control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition.

Assay: Enzymatic Inhibition Assay: 11-point dosing series were made for each compound by serially diluting 1:3 or 1:4 in DMSO, with point 12 being a DMSO control. From the serial dilution plates, sample was transferred to a 384 wells assay plate (#781280, Greiner, Monroe, N.C.) using Labcyte Echo (Sunnyvale, Calif.), or Biosero ATS (San Diego, Calif.). The compounds were tested in duplicate. Column 12 was used for positive controls, and column 24 contained negative controls with no enzyme added. A compound from our internal collection, with inhibitory activity for JAK isoforms, was used as a reference compound. The final concentration of DMSO was ≤0.25% in a 20 μL reaction. Assay conditions for each of the proteins are summarized in Table 3. The enzyme reaction was initiated by the addition of 10 μL of 2× enzyme and ATP mixture to 10 μL of 2× substrate solution prepared in reaction buffer (50 mM MOPS pH 7.5, 10 mM MgCl2, 1 mM EDTA, 2 mM DTT, 0.002% Tween-20). The Tyk2 enzyme was pre-incubated with 2 mM ATP for 30 min prior to the reaction initiation. Immediately after the addition of the enzyme to the reaction mixture, the plate was centrifuged at 1000 rpm for 1 minute and incubated at 25° C. for 45 minutes for JAK 3 and 90 minutes for JAK1, JAK2 and Tyk2. The reaction was quenched by the addition of 20 μL of 0.5% TFA containing 0.15 μM of internal standard peptide using Multidrop Combi reagent dispenser (Thermo Scientific, Waltham, Mass.). Several wells in column 24 were typically used for the product standard curve. After the quench, the assay plate was centrifuged at 3000 rpm for 3 minutes and sealed with pierceable aluminum foil (Cat #06644-001, Agilent) using a PlateLoc (Agilent Technologies, Santa Clara, Calif.). The plates then were transferred on to the RapidFire for the MS analysis. Compound inhibition was assessed by a decrease of the phosphorylated product levels in sample wells compared to the non-inhibited enzyme reaction.

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-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. 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.

In assay buffer containing 12.5 mM HEPES pH 7.4, 75 mM NaCl, 1 mM MgCl2, 1 mM BME, 5 uM Cyclophilin A and 2 uM test compound, a 5 uM stock of GMP-PNP-loaded K-Ras (1-169) G12C is diluted 10-fold to yield a final concentration of 0.5 uM; with final sample volume being 100 uL. The sample is incubated at 25�� C. for a time period of up to 24 hours prior to quenching by the addition of 10 uL of 5% Formic Acid. Quenched samples are centrifuged at 15000 rpm for 15 minutes in a benchtop centrifuge before injecting a 10 uL aliquot onto a reverse phase C4 column and eluting into the mass spectrometer with an increasing acetonitrile gradient in the mobile phase. Analysis of raw data may be carried out using Waters MassLynx MS software, with % bound calculated from the deconvoluted protein peaks for labeled and unlabeled K-Ras.

Assay: Binding Assay: Binding affinity (Ki) of compounds was measured by inhibition of radioligand binding to membranes from CHO cells expressing human M1, M2, M3, M4 and M5 receptors. Membranes were prepared by nitrogen cavitation and differential centrifugation as previously described (Hoare et al., Mol. Pharmacol. 2003 March; 63(3): 751-65). The radioligand employed was tritiated N-methylscopolamine, used at a concentration of 1.5 nM. A dose-response of twelve concentrations of compound was used, ranging from 10 Î¼M to 32 Î¼M. The assay buffer was 50 mM HEPES, 100 mM NaCl, 5 mM MgCl2, 1 mM ethylenediaminetetraacetic acid, pH-adjusted to pH 7.4.
