UniProt: P17948
Assay: FLIPR (Fluorometric Imaging Plate Reader) Technology Assay: Automated FLIPR (Fluorometric Imaging Plate Reader) technology was used to screen for inhibitors of PDGF induced increases in intracellular calcium levels in fluorescent dye loaded endothelial cells. NHDF-Ad (Normal human dermal fibroblasts) (Lonza) were seeded in 384-well fibronectin coated black-walled plates overnight at 37° C./5% CO2. Cells were loaded with calcium indicator Fluo-4 for 45 minutes at 37° C. Cells were washed 4 times (ELx405-CW, Bio-Tek) to remove extracellular dye. Test compounds were reconstituted in 100% DMSO and added to the cells to give a final DMSO concentration of 0.1%. For screening, cells were pre-incubated with test agents for 30 minutes, at a single concentration (10 μM) or at concentrations ranging from 0.001 nM to 10 μM followed by PDGF stimulation (10 ng/mL). Changes in fluorescence at 515 nm were measured simultaneously in all 384 wells using a cooled CCD camera.

Target: Lysophosphatidic acid receptor 1 (SINGLE PROTEIN), Homo sapiens
UniProt: Q92633
Assay: In Vitro LPA1 Receptor Assay: Engagement of the LPA1 receptor by its ligand, oleoyl-L-α-lysophosphatidic acid (LPA), leads to the release of intracellular stores of calcium into the cytoplasm mediated through a Gq-driven increase in inositol triphosphate (IP3) levels. Gq is a heterotrimeric G protein subunit that activates phospholipase C.The ability of test compounds to prevent LPA-driven intracellular release of stored calcium from RH7777 cells expressing human LPA1 receptors was assayed by stimulating the cells with LPA in the presence of various test compounds to measure the test compounds' antagonism, i.e. activity in vitro. Approximately 10,000 cells in normal culture medium (Dulbecco's Modified Eagle Media, 10% Foetal Calf Serum) were dispensed per assay well in a black clear bottom collagen coated 384 well plate (Beckton Dickinson). Cells were allowed to settle for thirty minutes at room temperature before being incubated overnight at 37° C., 5% CO2. Sixteen to twenty hours after dispensing, the cells were loaded with a calcium-sensitive fluorescent dye by replacing the culture medium with assay buffer (1× Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH7.4) containing 1.25 mM probenecid and 1× Calcium 5 Reagent (Molecular Devices). Cells were incubated at 37° C. for one hour to allow for dye uptake. To test for antagonist activity, test compounds at a final concentration range between 0.32 nM-10 μM (diluted in assay buffer) were added to the assay wells and allowed to incubate for twenty five minutes. After incubation with test compounds the assay plate was placed in a FLIPR Tetra system (Molecular Devices) and LPA (diluted in assay buffer) was added to give a final concentration equivalent to its determined EC80 against LPA1 receptor. Ligand-dependent changes in intracellular calcium levels were determined by measuring changes in fluorescence of the dye over 515-575 nM following excitation over 470-495 nM.

Assay: cAMP Assay: CHO cells expressing human CB1 or CB2 receptors are seeded 17-24 hours prior to the experiment 50.000 cells per well in a black 96 well plate with flat clear bottom (Corning Costar #3904) in DMEM (Invitrogen No. 31331), 1×HT supplement, with 10% fetal calf serum and incubated at 5% CO2 and 37° C. in a humidified incubator. The growth medium was exchanged with Krebs Ringer Bicarbonate buffer with 1 mM IBMX and incubated at 30° C. for 30 min. Compounds were added to a final assay volume of 100 μl and incubated for 30 min at 30° C. Using the cAMP-Nano-TRF detection kit the assay (Roche Diagnostics) was stopped by the addition of 50 μl lysis reagent (Tris, NaCl, 1.5% Triton X100, 2.5% NP40, 10% NaN3) and 50 μl detection solutions (20 μM mAb Alexa700-cAMP 1:1, and 48 μM Ruthenium-2-AHA-cAMP) and shaken for 2 h at room temperature. The time-resolved energy transfer is measured by a TRF reader (Evotec Technologies GmbH), equipped with a ND:YAG laser as excitation source. The plate is measured twice with the excitation at 355 nm and at the emission with a delay of 100 ns and a gate of 100 ns, total exposure time 10 s at 730 (bandwidth 30 nm) or 645 nm (bandwidth 75 nm), respectively. The FRET signal is calculated as follows: FRET=T730-Alexa730-P(T645-B645) with P=Ru730-B730/Ru645-B645, where T730 is the test well measured at 730 nM, T645 is the test well measured at 645 nm, B730 and B645 are the buffer controls at 730 nm and 645 nm, respectively. cAMP content is determined from the function of a standard curve spanning from 10 μM to 0.13 nM cAMP.

Assay: In Vitro Assay: Human recombinant PDE10A2 was expressed in Sf9 cells, using a recombinant baculovirus construct containing the full length sequence containing a 6Ã¿His sequence following the start Met to allow metal affinity purification of the recombinant protein. Cells were harvested and the phosphodiesterase protein was purified by metal chelate chromatography on Ni-sepharose 6FF.The affinity of the compounds of Formula (I) for phophodiesterases (PDE) was measured by a scintillation proximity assay (SPA). PDE Yttrium Silicate SPA beads allow PDE activity to be measured by direct binding of the primary phosphate groups of non-cyclic AMP or GMP to the beads via a complex iron chelation mechanism. The amount of bound tritiated product ([3H]-AMP) is measured by liquid scintillation counting.The compounds were dissolved and diluted in 100% DMSO in polystyrene plates to a concentration of 100-fold the final concentration in the assay. Human PDE10A enzyme solution (10 uL) was added.

Target: Dihydroorotate dehydrogenase (quinone), mitochondrial (SINGLE PROTEIN), Homo sapiens
UniProt: Q02127
Assay: Method for Testing Activities of Compounds at Enzyme Level: Principles of activity test at enzyme level: firstly, dihydroorotate (DHO) is oxidatively dehydrogenated by DHODH to form orotic acid (Orotate, OA), accompanied by reduction of Flavin mononucleotide (FMN) into reduced flavin mononucleotide (FMNH2) by accepting 2H+ and 2e−, then coenzyme Q (CoQ) as hydrogen acceptor accepting electron and proton from FMNH2 is reduced into reduced coenzyme Q (CoQH2), reduced coenzyme Q transfers electrons to a chromogenic substrate, diclofenac sodium salt (DCIP), and finally DCIP was reduced. DCIP shows maximum absorption at 600 nm, while the reduced DCIP does not show absorption at 600 nm. The degree to which the substrate DHO is oxidized can be judged based on the degree of decrease in absorbance. The degree of oxidation of the substrate DHO per unit time is the initial rate of the enzymatic reaction. Upon addition of a inhibitor, the initial rate of the enzymatic reaction is reduced.The purified DHODH was diluted to 10 nM with a test buffer (50 mM HEPES, pH 8.0, 150 mM KCl, 0.1% Triton X-100), and coenzyme Q and DCIP were added to a final concentration of 100 μM and 120 μM, respectively, mixed well, added into a 96-well plate and incubated for 5 min at room temperature. Substrate DHO was added to start the reaction with a DHO final concentration of 500 μM. The absorbance was read at 600 nm using a BioTek microplate reader and read every 30 s for 6 min. For inhibitor activity test, different concentrations of inhibitors were added into the above reaction system, the initial rate of enzymatic reaction when no inhibitor was added was V0, and the initial rate of enzymatic reaction after an inhibitor was added was Vi, and the inhibition rate of a compound was calculated by the formula (1−Vi/V0)×100%. For calculating IC50 of a compound, Origin 8.0 was used to test the inhibition rate at least 8 concentrations. In the experimental procedure, Brequinar (purchased from Sigma-Aldrich Reagent) was used as a positive control and at least three parallels were set in each experiment.

Assay: Biological Assay: 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 (1× Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH 7.4) containing 1 mM probenecid and 1× 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 μM (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 to excitation at 485 nM.

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: Cytochrome P450 Inhibition: Protocol 1: Studies were carried out in human liver microsomes. Human liver microsomes were purchased from BD Gentest. DMSO stocks were prepared for the test compounds. Aliquots of the DMSO solutions were diluted 1:3 by acetonitrile:ACN mixture (v/v: 40:60) to "400×" intermediate solutions, then further diluted by liver microsomes/buffer to "2×" intermediate solutions. "2×" intermediate solutions were mixed with "2×" NADPH/substrate solutions, which had been pre-warmed to 37° C. (final test compound concentrations were 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, 0.122 μM, 0.041 μM, 0.0136 μM, and 0 μM). The plates were kept in a 37° C. water bath for the duration of the experiment. At the end of incubation (5 minutes for 3A4; 45 minutes for 2C19; 10 minutes for 1A2, 2C9, 2D6), 120 μL of acetonitrile was added into corresponding wells. After the final time point was sampled, the plates were shaken at a vibrator (IKA, MTS 2/4) for 10 mM (600 rpm/min) and then centrifuged at 5594 g for 15 mM (Thermo Multifuge×3R). Aliquots of the supernatant were removed, diluted 1:1 into distilled water, and analyzed by LC-MS/MS. The peak area response ratio to internal standard (PARR) of the compounds at 10 μM, 3.3 μM, 1.1 μM, 0.37 μM, 0.122 μM, 0.041 μM, and 0.0136 μM was compared to the PARR at 0 μM to determine the percent of metabolite generation from substrate at each test compound concentration.

Assay: ThermoFluor® Assay: Bar-coded assay plates are robotically loaded onto a thermostatically controlled PCR-type thermal block and then heated at a typical ramp-rate of 1 °C./min for all experiments. Fluorescence was measured by continuous illumination with UV light (Hamamatsu LC6) supplied via fiber optic and filtered through a band-pass filter (380-400 nm; >6 OD cutoff). Fluorescence emission of the entire 384-well plate was detected by measuring light intensity using a CCD camera (Sensys, Roper Scientific) filtered to detect 500±25 nm, resulting in simultaneous and independent readings of all 384 wells. Images were collected at each temperature, and the sum of the pixel intensity in a given area of the assay plate was recorded versus temperature. Reference wells contained RORγt without compounds, and the assay conditions were as follows: 0.065 mg/mL RORγt, 60 μM 1,8-ANS, 100 mM Hepes, pH 7.0, 10 mM NaCl, 2.5 mM GSH, 0.002% Tween-20. Project compounds were arranged in a pre-dosed mother plate (Greiner Bio-one) wherein compounds are serially diluted in 100% DMSO by 1:2 from a high concentration of 10 mM over 12 columns within a series (column 12 is a reference well containing DMSO, no compound). The compounds were robotically dispensed directly into assay plates (1×=46 nL) using a Hummingbird capillary liquid handling instrument (Digilab). Following compound dispense, protein and dye in buffer was added to achieve the final assay volume of 3 μL, followed by 1 μL of silicone oil.

Assay: Competitive Inhibition Binding Assay: A competitive inhibition binding assay was performed using membrane homogenates prepared from HEK-293 cells that express recombinant hMCR-1a or hMCR-4 (in each instance where the h prefix refers to human), or alternatively membrane homogenates from B16-F10 mouse melanoma cells containing endogenous murine MCR-1. In the examples that follow, all MCR-1 and MCR-4 values are for human recombinant receptors, unless otherwise noted. Assays were performed in 96 well polypropylene round-bottom plates (VWR catalog number 12777-030). Membrane homogenates were incubated with 0.1 nM [I125]-NDP-α-MSH (Perkin Elmer) and increasing concentrations of test peptides of the present invention in buffer containing 25 mM HEPES buffer (pH 7.5) with 100 mM NaCl, 2 mM CaCl2, 2 mM MgCl2, 0.3 mM 1,10-phenanthroline, and 0.2% bovine serum albumin. After incubation for 90 minutes at 37° C., the assay mixture was filtered onto GF/B Unifilter plates (Perkin-Elmer catalog number 6005177) and washed with 3 mL of ice-cold buffer per well. Filters were air dried and 35 uL of scintillation cocktail added to each well. Plates were counted in a Microbeta counter for bound radioactivity. Non-specific binding was measured by inhibition of binding of [I125]-NDP-α-MSH in the presence of 1 uM NDP-α-MSH. Maximal specific binding (100%) was defined as the difference in radioactivity (cpm) bound to cell membranes in the absence and presence of 1 uM NDP-α-MSH. Each assay was conducted in duplicate and the actual mean values are described, with results less than 0% reported as 0%. Ki values for peptides of the present invention were determined using Graph-Pad Prism curve-fitting software.

Target: Sodium channel protein type 5 subunit alpha (SINGLE PROTEIN), Homo sapiens
UniProt: Q14524
Assay: In Vitro Assay: HEK 293 cells stably transfected with either Nav 1.7 or with Nav 1.5 were recorded in population patch-clamp mode with the IonWorks® Quattro automated electrophysiology system in accordance with the manufacturer's specifications (Molecular Devices, LLC, Sunnyvale, Calif.). Sodium channel currents were measured in response to a train of depolarizations that induced successively greater inactivation. Cells were held at −110 mV for three seconds (Nav 1.7) or half a second (Nav 1.5) from a holding voltage of −15 mV, then put through a series of 26 pulses of 150 msec duration to −20 mV at a frequency of 5 Hz. Cells were then left unclamped for a period of 3 to 8 minutes while a single concentration of test compound was added. Cells were then reclamped and put through the same voltage protocol. Current at the end of the 26th pulse to −20 mV was subtracted from the peak current evoked by the 26th pulse to −20 mV to correct for leak current.
