Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P11309
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): 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 384-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 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer]. Final concentrations either Pim-1 enzyme [5 pM], or Pim-2 enzyme [0.5 pM], DMSO [1%], BLC BAD (S112) [0.5 μM], ATP [1.5 μM], streptavidin:Allophycocyanin [0.002 mg/mL] and biotinylated-BAD (S112) mAb [100 pM]. Initial incubations were carried out at RT (22° C.) for 30 min for both Pim-1 and for Pim-2. Pim enzyme is added to compound in buffer, and plates are incubated of 30 min. Biotinylated BAD and ATP are added and plates are incubated for 1 h. A mixture of labeled p-BAD (S112) mAb and quench/detection buffer are added and incubated for 2 h. Fluorescence was measured by an HTRF® Envision microplate reader.

Assay: Scintillation Proximity Assay (SPA): A SPA membrane binding assay was used to identify inhibitors of [33P] 2MeS-ADP binding to cloned human P2Y1 receptors (The P2Y1 receptor membranes were provided by Biology and the cloning of the receptor and P2Y1 receptor membrane preparation is same as described by Biology). Binding reactions were performed in 384-well OptiPlates (PerkinElmer Life Sciences, Cat #6007299) in a volume of 50 uL containing 15 fmol of P2Y1 receptor (1.7 ug of total protein), 0.3 nM [33P] 2MeS-ADP (PerkinElmer; 2,000 Ci/mmol), various concentrations of the test compound (usually between 10 uM and 160 pM) in Buffer B containing 1% DMSO in assay buffer (15 mM, HEPES, 145 mM potassium chloride, 5 mM sodium Chloride, 5 mM EDTA, 0.1 mM MgCl2, pH 7.4) and 100 ug of SPA bead (WGA polystyrene Image beads, #RPNQ 0260V, Amersham). Reactions were allowed to proceed to completion at room temperature for 1 hour followed by centrifugation of the plate for 5 min. About 40 uL of the aqueous soluttion was aspirated. Plates were sealed and the [33P] 2MeS-ADP bound to the P2Y1 receptor membranes that were bound to the SPA bead were determined in a Gen 4 LEADSEEKERSM (Amersham) Image Reader. Dose-response curves (IC50) were fit by non-linear regression (Toolset an in house data processing program) and binding constants (Ki) calculated using the Cheng-Prusoff relationship (Ki=IC50/(1+L/Kd) in which a Kd for 2MeS-ADP to the P2Y1 receptor was determined to be 14 nM.

Assay: Fluorescence Polarization (FP) Assay: Fluorescent polarization experiments were performed as follows. Briefly, the fluorescence polarization experiments were read on an Ultra Evolution 384-well plate reader (Tecan) with the 485 nm excitation and 535 nm emission filters. The fluorescence intensities parallel (Intparallel) and perpendicular (Intperpedicular) to the plane of excitation were measured in parallel perpendicular black 384-well NBS assay plates (Corning) at room temperature (20° C). The background fluorescence intensities of blank samples containing the references buffer were subtracted and steady-state fluorescence polarization was calculated using the equation: P=(Intparallel Gintperpendicular)/(Intparallel+Gintperpendicular), and the correction factor G (G=0.998 determined empirically) was introduced to eliminate differences in the transmission of vertically and horizontally polarized light. All fluorescence polarization values were expressed in millipolarization units (mP).

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: [35S]GTPgammaS Binding Assay: The frozen cell membrane fraction prepared as described above was thawed before use, and the resultant was diluted with a buffer for a binding assay (final concentrations: 20 mM HEPES, 100 mM NaCl, 1 mM MgCl2, 3 uM GDP, 300 ug/mL saponin, 0.1% BSA). The compound of each example was added to a cell membrane fraction containing 1.8 to 3 ug/assay of membrane protein on a plate, followed by incubation at room temperature for 30 minutes. Thereafter, with glutamic acid (in a final concentration of 10 uM) added thereto, incubation was performed at room temperature for 15 minutes, and thereafter, [35S]GTPγS (in a final concentration of 0.8 kBq) and 588 ug WGA-SPA beads were added thereto, followed by incubation at room temperature for 1 hour. After the incubation, the plate was subjected to the centrifugal separation at 2,500 rpm and room temperature, and then, membrane cell binding radioactivity was measured with a top count. A [35S]GTPγS binding amount obtained in the presence of glutamic acid was defined as specific binding. On the basis of ratios of inhibiting the specific binding at various concentrations of the compounds of the respective examples, inhibition curves were obtained. Concentrations of the compounds of the respective examples at which the specific [35S]GTPγS binding amount was suppressed by 50% (IC50 values) were calculated on the basis of the inhibition curves.

Assay: Radioligand Binding Assay: Assessments of compound binding to human MC5R (hMC5R)) by displacement of an 125I-labeled NDP-MSH receptor ligand peptide were performed essentially as described in the data sheets produced by Perkin Elmer to accompany their frozen hMC5R membranes (Perkin Elmer catalog number RBXMC5M400UA). [125I] NDP-MSH: Radiolabeled in House and Purified by HPLC: Na125I (0.5 mCi, 17.4 Ci/mg) was added to 50 μL sodium phosphate (50 mM, pH 7.4) in an eppendorf tube precoated with IODOGEN. After incubation for 10 mins the phosphate buffer containing the iodine was added to NDP-MSH (10 μl at 1 mg/mL) in a separate eppendorf tube. This was incubated for a further 10 mins. The iodinated NDP-MSH was purified by HPLC on a Zorbax SB 300 column using solvent A: 0.05% TFA and solvent B: 90% acetonitrile 0.045% TFA with a linear gradient, 0-67% B over 60 mins. The 125I NDP-MSH eluted at 52 mins after the unlabeled starting material (48 min) and was counted and stored in the freezer. It was used within 48 hrs, as radioactive decay and ligand decomposition resulted in greatly reduced specific binding observed after 72 hrs. Incubation buffer: 25 mM HEPES-KOH (pH 7.0), 1.5 mM CaCl2, 1 mM MgSO4, 0.1 M NaCl, 1 mM 1,10-phenanthroline, and 1 Complete™ protease inhibitor tablet/100 mL (Roche, catalog number 1873580). Perkin Elmer frozen hMC5 membranes: catalog number RBXMC5M400UA, 0.4 mL/vial; 400 microassays/vial, 0.78 mg/mL protein concentration. Vials of frozen membranes were thawed rapidly immediately before use, diluted with binding buffer and vortexed. Resuspended membranes were kept on ice until they were added to the wells of the plate. Assays were performed in 96 well polypropylene plates. Membranes (0.78 μg 40 μL of a 1:40 dilution in incubation buffer) were added to [125I] NDP-MSH (0.84 nM; 2200 Ci/mmol) and test compounds in a total volume of 140 μL. This was incubated for 1 hr at 37° C. Non-specific binding was determined with 3 mM NDP-MSH. Plates were filtered using a Tomtec cell harvester with GF/A filters (Wallac) (presoaked in 0.6% polyethylenimine) and washed three times with 1.0 mL ice-cold wash buffer (the above incubation buffer without 1,10-phenanthroline and Complete™ protease inhibitor tablet). The filters were dried in a 37° C. oven, placed in a sample bag and 5 mL Betaplatescint (Wallac) was added. Prepared filters were counted in cassettes in a Microbeta Trilux (Wallac) for 1 min.

Assay: Enzyme Assay: JAK1, JAK2, JAK3 and Tyk2 were purchased from Carna Biosciences, Inc. As the substrate, LANCE Ultra ULight-JAK1 Peptide (manufactured by PerkinElmer Co., Ltd. (PE)) was used. Dilute solutions of compounds and enzymes in assay buffer (50 mM HEPES pH7.5, 1 mM EGTA, 1 mM MgCl2, 2 mM DTT, 0.01% Tween20) were dispensed into wells of a 384-well black plate. After 5 minutes of preincubation, dilute solutions of the substrate and ATP (adenosine triphosphate) were added at a final concentration of 100 μM, and the plate was incubated at room temperature for 2 hours. After addition of a termination reagent containing EDTA (ethylenediamine tetraacetic acid) at a final concentration of 10 mM, LANCE Eu-W1024 Anti-phosphotyrosine (PT66) (manufactured by PE) was added, and after 1 hour of incubation, the fluorescences were measured with ARVO-HTS.

Assay: Biochemical Assay: A solution of test compound was added to a diluted microsome preparation containing human mPGES-1 and pre-incubated for 15 minutes in potassium phosphate buffer pH 6.8 with cofactor glutathione (GSH). Corresponding solutions without test compound were used as positive controls, and corresponding solutions without test compound and without microsomes were used as negative controls. The enzymatic reaction was then started by addition of the substrate PGH2 in an organic solution (dry acetonitrile).The typical reaction conditions of the enzymatic reaction were thus: Test compound: ranging from 60 uM to 0.002 uM, or zero in positive and negative controls; potassium phosphate buffer pH 6.8: 50 mM; GSH: 2.5 mM; mPGES-1-containing microsomes: 2 ug/mL (sample and positive controls) or 0 ug/mL (negative control); PGH2: 10.8 uM; Acetonitrile: 7.7% (v/v); DMSO: 0.6% (v/v). The reaction was stopped after one minute by adding an acidic solution (pH 1.9) of ferric chloride.
