Assay: Fluorescence Polarization Competition Immunoassay: An autophosphorylation, fluorescence polarization competition immunoassay was used to determine the potency for c-fms inhibition exhibited by selected compounds of Formula I. The assay was performed in black 96-well microplates (LJL BioSystems). The assay buffer used was 100 mM 4-(2-hydroxyethyl)piperazine 1-ethanesulfonic acid (HEPES), pH 7.5, 1 mM 1,4-dithio-DL-threitol (DTT), 0.01% (v/v) Tween-20. Compounds were diluted in assay buffer containing 4% dimethylsulfoxide (DMSO) just prior to the assay. To each well, 5 μL of compound were added followed by the addition of 3 μL of a mix containing 33 nM c-fms (Johnson & Johnson PRD) and 16.7 mM MgCl2 (Sigma) in assay buffer. The kinase reaction was initiated by adding 2 μL of 5 mM ATP (Sigma) in assay buffer. The final concentrations in the assay were 10 nM c-fms, 1 mM ATP, 5 mM MgCl2, 2% DMSO. Control reactions were ran in each plate: in positive and negative control wells, assay buffer (made 4% in DMSO) was substituted for the compound; in addition, positive control wells received 1.2 μL of 50 mM ethylenediaminetetraaceticacid (EDTA). The plates were incubated at room temperature for 45 min. At the end of the incubation, the reaction was quenched with 1.2 μL of 50 mM EDTA (EDTA was not added to the positive control wells at this point; see above). Following a 5-min incubation, each well received 10 μL of a 1:1:3 mixture of anti-phosphotyrosine antibody, 10×, PTK green tracer, 10× (vortexed), FP dilution buffer, respectively (all from PanVera, cat. #P2837). The plate was covered, incubated for 30 min at room temperature and the fluorescence polarization was read on the Analyst. The instrument settings were: 485 nm excitation filter; 530 nm emission filter; Z height: middle of well; G factor: 0.93. Under these conditions, the fluorescence polarization values for positive and negative controls were approximately 300 and 150, respectively, and were used to define the 100% and 0% inhibition of the c-fms reaction.

Assay: Radioligand Binding Assay: Displacement assays for determination of Ki values of test compounds were performed with [3H]-NMS at 1 nM and eleven different test compound concentrations. The test compounds were initially dissolved to a concentration of 400 μM in dilution buffer and then serially diluted 5× with dilution buffer to final concentrations ranging from 10 pM to 100 μM. The order of addition and volumes added to the assay plates were as follows: 25 μL radioligand, 25 μL diluted test compound, and 50 μL membranes. Assay plates were incubated for 6 hours at 37° C. Binding reactions were terminated by rapid filtration over GF/B glass fiber filter plates (PerkinElmer, Inc.) pre-treated in 1% BSA. Filter plates were rinsed three times with wash buffer (10 mM HEPES) to remove unbound radioactivity. The plates were then air-dried and 50 μL Microscint-20 liquid scintillation fluid (PerkinElmer, Inc.) were added to each well. The plates were then counted in a PerkinElmer Topcount liquid scintillation counter (PerkinElmer, Inc.).

Assay: PIM Kinase Binding Assay: LC3K assay: PIM-1, -2, and -3 enzymes were generated as fusion proteins expressed in bacteria and purified by IMAC column chromatography (Sun, X., Chiu, J. F., and He, Q. Y. (2005) Expert Rev. Proteomics, 2:649-657). A fluorescent-labeled Pim-specific peptide substrate, was custom synthesized by American Peptide Company (Sunnyvale, Calif.). Reaction Buffer contained 10 mM HEPES, pH 7.2, 10 mM MgCl2, 0.01% Tween 20, 2 mM DTT. Termination Buffer contained 190 mM HEPES, pH 7.2, 0.015% Brij-35, 0.2% Coating Reagent 3 (Caliper Life Sciences, Hopkinton, Mass.), 20 mM EDTA. Separation Buffer contained 100 mM HEPES, pH 7.2, 0.015% Brij-35, 0.1% Coating Reagent 3, 1:200 Coating Reagent 8 (Caliper Life Sciences, Hopkinton, Mass.), 10 mM EDTA and 5% DMSO. PIM reactions were carried out in a final volume of 10 μL per well in a 384-well plate. A standard enzymatic reaction, initiated by the addition of 5 μL 2×ATP and test compound to 5 μL of 2× enzyme and FAM-peptide, contained 20 pM PIM1, 50 pM PIM2, or 55 pM PIM3, 1 μM FAM-peptide, and 10 μM ATP, in Reaction Buffer. After 90 minutes of incubation at room temperature, the phosphorylation reaction was stopped by the addition of 10 μL Termination Buffer. The product and substrate in each independent reaction were separated on a 12-sipper microfluidic chip (Caliper Life Sciences, Hopkinton, Mass.) run on a Caliper LC3000® (Caliper Life Sciences, Hopkinton, Mass.). The separation of product and substrate was optimized by choosing voltages and pressure using Caliper's Optimizer software (Hopkinton, Mass.). The separation conditions used a downstream voltage of −500V, an upstream voltage of −2150V, and a screening pressure of −1.2 psi. The product and substrate fluorophore were excited at 488 nm and detected at 530 nm.

Assay: FRET-Based Membrane Potential Assay: Two days prior to the experiment, frozen HEK293 cells stably expressing recombinant human Nav1.7 were quickly thawed and plated at 25,000 cells/well in growth medium [DMEM (Invitrogen #11965) with 10% HI FBS (Invitrogen #10082), 2 mM glutamine, 100 units/mL penicillin, 0.1 mg/mL streptomycin (PSG, Sigma #G1146), and 500 ug/mL Geneticin (Invitrogen #10131)] in black-walled, clear-bottom 384-well poly-D-lysine-coated assay plates (Greiner Bio-One, Frickenhausen, Germany) and incubated in a humidified 5% CO2 incubator at 37° C. On the day of the assay, medium was removed by aspiration, and cells were washed with assay buffer [HBSS (Invitrogen, Carlsbad, Calif.) containing 20 mM HEPES (Invitrogen, Carlsbad, Calif.)]. After washing, 30 uL assay buffer containing the fluorescent voltage-sensor probe CC2-DMPE (Invitrogen, Carlsbad, Calif.) at 20 uM and 0.01% pluronic F-127 (Invitrogen, Carlsbad, Calif.) was added to the cells. Cells were incubated for 40 minutes at room temperature in the dark. Following the incubation, the cells were washed and 30 uL assay buffer containing 2.5 uM DiSBAC2(3) substrate (Invitrogen, Carlsbad, Calif.) and 0.5 mM VABSC-1 (Invitrogen, Carlsbad, Calif.) was added to the cells. The cells were incubated for 90 minutes at room temperature in the dark. Fluorescence readings were made using a FLIPR TETRA (Molecular Devices, Sunnyvale Calif.) equipped with voltage-sensor probe optics. At the start of each experiment the optimal (EC80) concentration of depolarizing agent (veratridine) was determined by testing a dilution curve of assay buffer containing veratridine (Sigma-Aldrich, St. Louis, Mo.) and 1 mg/mL scorpion venom (SVqq, from Leiurus quinquestriatus; Sigma-Aldrich, St. Louis, Mo.). Compounds were dissolved in dimethyl sulfoxide, and 8-point, 1:3 dilution concentration-response curves were prepared in duplicate in dimethyl sulfoxide, followed by preparation of 0.8 uL/well daughter plates of the dilutions. Test compounds in the daughter plate were diluted to (Ë¿3x) solutions in assay buffer immediately before assaying. Using the FLIPR TETRA, 20 uL of the (3x) compound solutions were first added to the cells, then 20 uL of depolarizing solution (3xEC80 veratridine+SVqq) were added 3 minutes later to activate the channel. Changes in fluorescence were measured at wavelengths of 440-480 nm and 565-625 nm over the course of the experimental run. Membrane depolarization was expressed as a ratio of the maximum F440-480 nm/F565-625 nm reading above average baseline F440-480 nm/F565-625 nm reading. IC50 values were calculated from curve fits of the ratio data using a four-parameter logistic Hill equation (Accelrys Assay Explorer 3.3 Client, Accelrys, San Diego, Calif.) with percent inhibition plotted against compound concentration.

Assay: Activity Assay: A human acute lymphoblastic lymphoma T cell line MOLT-4 (which can be purchased under ATCC No. CRL-1582 from ATCC) was cultured in an RPMI1640 medium containing 10% fetal bovine serum to obtain 5108 MOLT-4 cells. The cells were recovered by centrifugation and suspended in 10 ml of buffer solution A (25 mM Tris-HCl, 5 mM 2-mercaptoethanol, 2 mM benzamidine, 2 mM EDTA, and 0.1 mM 4-(2-aminoethyl)benzenesulfonyl hydrochloride, pH 7.5). The cells were homogenized using a Polytron homogenizer and centrifuged (4° C., 25,000 g, 10 minutes). Then, the supernatant was further ultracentrifuged (4° C., 100,000 g, 60 minutes). The obtained supernatant was filtered through a 0.2um filter to obtain a soluble fraction.HiTrap Q HP column (5 ml2, GE Healthcare Japan Corp.) equilibrated with buffer solution A was charged with the obtained soluble fraction. Phosphodiesterase was eluted with 300 ml of buffer solution A containing a linear gradient solution of 0 to 0.8 M NaCl to recover sixty 5-ml fractions. Each fraction was tested for cAMP-metabolizing phosphodiesterase activity. In each fraction, a fraction eluted as an active peak centered around 250 mM NaCl was collected from fractions that had cAMP metabolic activity and did not lose the metabolic activity by 10uM rolipram (PDE4 selective inhibitor) and 10uM milrinone (PDE3 selective inhibitor). In order to confirm whether or not PDE10A mRNA was expressed in the MOLT-4 cells, total RNA was prepared from the MOLT-4 cells according to a standard method and analyzed by RT-PCR using PDE10A gene-specific primers (PDE10A sense primer: 5'-TGCTCCATGGTGGAAGTGGA-3' (SEQ ID NO: 1) and PDE10A antisense primer: 5'-CAACTGGAAGCATGCGGTCA-3' (SEQ ID NO: 2)). As a result, PDE10A mRNA was detected from the total RNA of the MOLT-4 cells. On the other hand, total RNA was prepared from Jurkat cells, one type of human T cell, and similarly subjected to RT-PCR. As a result, PDE10A mRNA was rarely detected. An active peak centered around 250 mM NaCl was not observed in fractions obtained by the treatment of Jurkat cells in the same way as above. Eur J Biochem. 1999, 266 (3), 1118-2 has reported that PDE10A from the rat striatum and testis is eluted as an active peak centered around 250 mM NaCl.

The ligand binding domain of human RORγ (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15 ug/well RORγ (A262-S507) is incubated with test compound at varying concentrations in 3-fold serial dilution, with final concentrations ranging from 16.6 uM to 0.28 nM for 10 min at room temperature in PBS buffer (Invitrogen #14190-144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% Glycerol (Sigma Cat#G5516). 10 nM of [3H] 25-hydroxycholesterol is then added, and the reaction is incubated for 10 min. 10 mg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat #RPNQ0095) are added, and the mixture is incubated for 60 min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC50 values were determined. The IC50 value is defined as the concentration of test compound needed to reduce [3H] 25-hydroxycholesterol specific binding by 50% and is calculated using the four parameter logistic equation to fit the normalized data.

Assay: Cell Based Assay: TRKA co-expressed with p75: The assays are based upon DiscoveRx's proprietary Enzyme Fragment Complementation (EFC) technology. In the case of the TRK cell lines, the enzyme acceptor (EA) protein is fused to a SH2 protein and the TRK receptor of interest has been tagged with a Prolink tag. Cryopreserved PathHunter cells are used from either in-house produced batches or bulk batches bought directly from DiscoveRx. Cryopreserved cells are resuscitated, spun 1000 rpm for 4 min to remove freezing media, and resuspended in MEM+0.5% horse serum (both Invitrogen) to 5e^5 cells/ml. The cells are then plated using a Multidrop into Greiner white tissue culture treated plates at 20 μl/well and incubated for 24 h at 37 °C., 5% CO2, high humidity. On the day of the assay, the cell plates are allowed to cool to room temperature for 30 min prior to the assay. 4 mM stock solutions of test compounds are prepared and serially diluted in 100% DMSO. A standard curve using the compound of Example 135, WO2005/116035 at a top concentration of 150 μM is also prepared on each test plate. High percentage effect (HPE) is defined by 150 μM of the compound of Example 135, WO2005/116035 and 0% effect (ZPE) is defined by 100% DMSO. Plates containing 1 μl of serially diluted compound, standard and HPE/ZPE are diluted 1/66 in assay buffer (PBS minus Ca2+, minus Mg2+ with 0.05% pluronic F127) using a Wellmate. Using a Platemate Plus, 5 μl of 1/66 diluted test compounds is then transferred to the cell plate and allowed to reach equilibrium by incubating for 30 min at room temperature before addition of agonist stimulus: 10 μl/well of 2 nM (0.571 nM FAC) of the cognate neurotrophin (Peprotech) diluted in agonist buffer (HBSS with 0.25% BSA). Final assay concentration of the test compounds is 8.66 μM, (the compound of Example 135, WO2005/116035 FAC is 0.325 μM). The plates are left at room temperature for a further 2 hours before addition of 10 μl of the DiscoveRx PathHunter detection reagent (made up by adding 1 part Galacton Star, 5 parts Emerald II and 19 parts Cell Assay Buffer as per the manufacturer's instructions). After reagent addition, plates are covered and incubated at room temperature for 60 minutes. Luminescence signal is read using an Envision.

Assay: Enzyme Assay: The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 96-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction.Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 10-point dosing curve having a high dose of 1 uM.

UniProt: Q15858
Assay: Cell-Based Assay: Compounds were tested on human Nav1.7 (hNav1.7) expressed stably in 293 cells, which have no endogenous sodium channels. Two forms of whole-cell patch-clamp assays were used. In both, peak current through Nav1.7 was evoked by a depolarizing voltage pulse, and currents were monitored as a function of time in response to exposure to several different concentrations of drug. Automated electrophysiology uses the PatchXpress 7000A system. Up to sixteen cells at a time were voltage-clamped in parallel, and the steady-state voltage dependence of inactivation was determined experimentally for each cell. For each cell, fractional inactivation was set at 20%, and peak current through Nav1.7 as a function of time was measured in response to increasing concentrations of test compound. Manual electrophysiology refers to conventional whole-cell patch-clamping (Hamill et al., 1981). After formation of the whole-cell clamp, cells were lifted off the bottom of the dish with the patch pipette and positioned directly in front of an array of glass microperfusion tubes each with internal diameter about 250 microns, with individual compound concentrations flowing from each tube. Current as a function of time in response to increasing drug concentrations was measured with Nav1.7 fully in the resting state (holding voltage set to −140 mV) and on the same cells with the holding voltage set to produce about 20% inactivation. Compounds were not applied for a prespecified time, but for as long as required to achieve a stable level of block.

Assay: Nav1.7 In Vitro PX Assay: HEK 293 cells stably transfected with human Nav1.7 were recorded in whole cell voltage clamp mode with the PatchXpress automated electrophysiology system (Molecular Devices, LLC, Sunnyvale, Calif.). Compound effects were measured on a partially inactivated state of the sodium channel. Cells were clamped to a holding potential yielding 20 to 50% inactivation. To elicit sodium current, channels were activated by pulsing to -10 mV for 20 msec. This voltage protocol was repeated at a rate of 0.1 Hz throughout the experiment. A single concentration of test compound was applied to cells for a duration of 3 minutes.
