Target: Prokineticin receptor 1 (SINGLE PROTEIN), Homo sapiens
UniProt: Q8TCW9
Assay: Biological Assay: Prokineticin receptor 1 (PKR1) antagonists may be functionally assessed by measurement of change in intracellular calcium levels induced by Gq mediated increase in inositol triphosphate (IP3) levels. The ability of a compound to block the intracellular release of calcium mediated by PK1 in RBL2H3 cells expressing human PKR1 receptors is determined as a measure of the compound's antagonist activity in vitro. Approximately 10,000 cells per assay well are seeded in normal culture medium in a 384 well plate (Corning). Twenty-four hours after seeding, the cells are loaded with a calcium sensitive fluorescent dye by replacing the culture medium with assay buffer (1xHanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH 7.4) containing 1 mM probenecid and 1x Calcium 5 Reagent (Molecular Devices). Cells are incubated at 37° C. for 1 hour to allow for dye uptake.To test for antagonist activity, test compounds at a final concentration range between 0.32 nM-10 uM (diluted in assay buffer) are added to the assay wells and allowed to incubate for 10 minutes prior to stimulation with PK1. After incubation with test compounds the assay plate is placed in a FLIPR Tetra (Molecular Devices) and PK1 (diluted in assay buffer) is added at the determined EC80 concentration (final). Ligand-dependent changes in intracellular calcium levels are determined by measuring changes in fluorescence of the dye at 525 nM following excitation at 485 nM. Readings from wells that do not contain antagonist enable percentage inhibition curves to be plotted using 4-parameter fit algorithm and IC50 values are calculated for each test compound.

Assay: Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay: The inhibition constant (Ki) is the dissociation constant of an enzyme-inhibitor complex or a protein/small molecule complex, wherein the small molecule is inhibiting binding of one protein to another protein or peptide. Where the Ki for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-XL) is greater than the limits of detection of the assay used. Where the binding selectivity ratio for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the selectivity of a particular compound for Bcl-2 over Bcl-XL is at least as great as the number indicated. Where the Ki for a compound is represented as < (less than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-2) is lower than the limit of detection of the assay used. Inhibition constants were determined using Wang's equation (Wang Z-X).

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: 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: Scintillation Proximity Assay (SPA): The binding of potential ligands to RORγ is measured by competition with [3H] 25-hydroxycholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA) binding assay. 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: Functional Assay: HEK293 cells were transfected with human TRPV1 cloned in pcDNA3.1zeo(+) using the Effectene non-liposomal lipid based transfection kit (Qiagen) (hTRPV1/HEK293). hTRPV1/HEK293 cells were routinely grown as monolayers under selection in zeocin (200 μg/mL; Invitrogen) in Dulbecco's Modified Eagle Medium (DMEM, Gibco BRL) supplemented with 10% fetal bovine serum, and penicillin/streptomycin (50 units/mL) in 5% CO2 at 37° C. Cells were passaged frequently, every 3-5 days, to avoid overgrowth, depletion of essential medium components, or acidic medium exposure. Cells were passaged using a brief wash in 0.05% trypsin with 1 mM EDTA, followed by dissociation in divalent-free phosphate-buffered saline (Hyclone #SH30028.02). Dissociated cells were seeded onto poly-D-lysine coated black-walled 96-well plates (Biocoat; Becton Dickinson #354640) at about 40,000 cells per well and grown for approximately 1 day in culture medium to near confluency. The assay buffer was composed of 130 mM NaCl, 2 mM KCl, 2 mM MgCl2, 10 mM HEPES, 5 mM glucose, and either 2 mM or 20 μM CaCl2. On the day of the experiment, the culture medium was replaced with 2 mM calcium assay buffer using an automated plate washer (ELx405; Biotek, VT). The cells were incubated in 100 μL/well Fluo-3/AM (2 μM; TEFLabs #0116) with Pluronic F127 (100 μg/mL; Sigma #P2443) for 1 h at rt in the dark. After loading the cells, the dye solution was replaced with 50 μL/well of 20 μM calcium assay buffer using the ELx405 plate washer. Test compounds (50 μL/well) were added to the plate and incubated for 30 min. Intracellular Ca2+ levels were subsequently assayed using a Fluorometric Imaging Plate Reader (FLIPR™ instrument, Molecular Devices, CA) to simultaneously monitor Fluo-3 fluorescence in all wells (λexcitation=488 nm, λemission=540 nm) during challenge with agonist (capsaicin). The IC50 values were determined. Cells were challenged with 150 nM capsaicin and the fluorescence counts were captured following agonist addition at a sampling rate of 0.33 Hz. The contents of the wells were mixed 3 times (40 μL mix volume) immediately after the additions were made. Concentration dependence of block was determined by exposing each well of cells in duplicate rows of a 96 well plate to a serial dilution of test compound. The concentration series usually started at 10 Î¼M with a three-fold serial decrement in concentration. The magnitude of the capsaicin response was determined by measuring the change in fluo3 fluorescence before and 100 seconds after the addition of the agonist.

Assay: Kinase Assay: For the assay 50 nL of a 100-fold concentrated solution of the test compound in DMSO was pipetted into a black low volume 384 well microtiter plate (Greiner Bio-One, Frickenhausen, Germany), 2 μl of a solution of Mps-1 in assay buffer [0.1 mM sodium-ortho-vanadate, 10 mM MgCl2, 2 mM DTT, 25 mM Hepes pH 7.7, 0.05% BSA, 0.001% Pluronic F-127] were added and the mixture was incubated for 15 min at 22° C. to allow pre-binding of the test compounds to Mps-1 before the start of the kinase reaction. Then the kinase reaction was started by the addition of 3 μl of a solution of 16.7 adenosine-tri-phosphate (ATP, 16.7 μM=>final conc. in the 5 μl assay volume is 10 μM) and peptide substrate (1.67 μM=>final conc. in the 5 μl assay volume is 1 μM) in assay buffer and the resulting mixture was incubated for a reaction time of 60 min at 22° C. The concentration of Mps-1 in the assay was adjusted to the activity of the enzyme lot and was chosen appropriate to have the assay in the linear range, typical enzyme concentrations were in the range of about 1 nM (final conc. in the 5 μl assay volume). The reaction was stopped by the addition of 3 μl of a solution of HTRF detection reagents (100 mM Hepes pH 7.4, 0.1% BSA, 40 mM EDTA, 140 nM Streptavidin-XLent [#61GSTXLB, Fa. Cis Biointernational, Marcoule, France], 1.5 nM anti-phospho(Ser/Thr)-Europium-antibody [#AD0180, Perkin Elmer LAS, Rodgau-Jügesheinn, Germany]. The resulting mixture was incubated 1 h at 22° C. to allow the binding of the phosphorylated peptide to the anti-phospho(Ser/Thr)-Europium-antibody. Subsequently the amount of phosphorylated substrate was evaluated by measurement of the resonance energy transfer from the Europium-labelled anti-phospho(Ser/Thr) antibody to the Streptavidin-XLent. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm was measured in a Viewlux TR-FRET reader (PerkinElmer LAS, Rodgau-Jügesheinn, Germany).

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: Electrophysiology Assay: Block of Kir1.1 (ROMK1) currents was examined by whole cell voltage clamp (Hamill et. al. Pfluegers Archives 391:85-100 (1981)) using the IonWorks Quattro automated electrophysiology platform (Molecular Devices, Sunnyvale, Calif.). Chinese hamster ovary cells stably expressing Kir1.1 channels were maintained in T-75 flasks in cell culture media in a humidified 10% CO2 incubator at 37 °C. Prior to an experiment, Kir1.1 expression was induced by overnight incubation with 1 mM sodium butyrate. On the day of the experiment, cells were dissociated with 2.5 ml of Versene (Invitrogen 15040-066) for approximately 6 minutes at 37 °C. and suspended in 10 ml of bath solution containing (in mM): 150 NaCl, 10 KCl, 2.7 CaCl2, 0.5 MgCl2, 5 HEPES, pH 7.4. After centrifugation, the cell pellet was resuspended in approximately 4.0 ml of bath solution and placed in the IonWorks instrument. The intracellular solution consisted of (in mM): 80 K gluconate, 40 KCl, 20 KF, 3.2 MgCl2, 3 EGTA, 5 Hepes, pH 7.
