Target: MAP kinase-activated protein kinase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: P49137
Assay: Inhibition Assay: Kinase reactions is carried out in a 384-well plate (Matrical, MP101-1-PP) in 20 mM HEPES pH 7.5, 10 mM MgCl2, 0.0005% Tween-20, 0.01% BSA, 1 mM DTT, and 2% DMSO. The inhibitor concentration is varied between 0.02-30,000 nM, while the Hsp27 peptide substrate and MgATP are held constant at 1 μM and 10 μM, respectively. Activated p38α is added to a final concentration of 20 pM for reactions with nonphosphorylated 1 nM His6-MK2 in the cascade reaction. For the p38α/PRAK cascade, unactivated GST-PRAK is held constant at 1 nM while p38α is added in to a final concentration of 20 pM. Kinase reactions are incubated at room temperature and quenched after 30 minutes by the addition of stop buffer (180 mM HEPES, 30 mM EDTA, and 0.2% Coating Reagent-3). Under these conditions, approximately 20% of the substrate Hsp27 peptide is phosphorylated. Reactions are initiated by the addition of activated p38α except for preincubation experiments, where reactions are initiated by the addition of Hsp27 peptide and MgATP. Preincubation of p38α with inhibitor or p38α with unactivated His6-MK2 or unactivated GST-PRAK and inhibitor are performed at 2X final assay concentrations at room temperature 240 minutes prior to adding ATP and Hsp27 peptide to initiate catalysis.

Target: Serine/threonine-protein kinase pim-3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q86V86
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. A reference compound was included on each assay plate in order to validate that plate; on

Target: Coagulation factor XI (SINGLE PROTEIN), Homo sapiens
UniProt: P03951
Assay: Measurement of FXIa Inhibition: To determine the factor XIa inhibition of the substances according to the invention, a biochemical test system is used which utilizes the reaction of a peptidic factor XIa substrate to determine the enzymatic activity of human factor XIa. Here, factor XIa cleaves from the peptic factor XIa substrate the C-terminal aminomethylcoumarin (AMC), the fluorescence of which is measured. The determinations are carried out in microtitre plates.Test substances are dissolved in dimethyl sulphoxide and serially diluted in dimethyl sulphoxide (3000 μM to 0.0078 μM; resulting final concentrations in the test: 50 μM to 0.00013 μM). In each case 1 μl of the diluted substance solutions are placed into the wells of white microtitre plates from Greiner (384 wells). 20 μl of assay buffer (50 mM of Tris/HCl pH 7.4; 100 mM of sodium chloride solution; 5 mM of calcium chloride solution; 0.1% of bovine serum albumin) and 20 μl of factor XIa from Kordia (0.45 nM in assay buffer) are then added successively. After 15 min of incubation, the enzyme reaction is started by addition of 20 μl of the factor XIa substrate Boc-Glu(OBzl)-Ala-Arg-AMC dissolved in assay buffer (10 μM in assay buffer) from Bachem, the mixture is incubated at room temperature (22° C.) for 30 min and fluorescence is then measured (excitation: 360 nm, emission: 460 nm). The measured emissions of the test batches with test substance are compared to those of control batches without test substance (only dimethyl sulphoxide instead of test substance in dimethyl sulphoxide), and the IC50 values are calculated from the concentration/activity relationships.

Assay: Discontinuous Radiometric Assay: Compounds may be evaluated as selective reversible inhibitors of AKR1C3 by screening them against homogeneous recombinant AKR1C1-AKR1C4 expressed in E. coli. In each case, a discontinuous radiometric assay may be used to monitor the inhibition of progesterone reduction (20-ketosteroid reduction) catalyzed by AKR1C1, the inhibition of Δ4-AD reduction (17-ketosteroid reduction) catalyzed by AKR1C3, and the inhibition of 5α-DHT reduction (3-ketosteroid reduction) catalyzed by AKR1C2 and AKR1C4 (by measuring the formation of 20α-hydroxyprogesterone, testosterone or 3α-androstanediol by radiochromatography). Secondary screens of the compounds of interest include: (a) a full-screen against all nine human recombinant AKR enzymes to ensure there are no-intended off-target effects (in this context AKR1B10 (retinal reductase; SEQ ID NO:5) has been shown to be potently inhibited by N-phenylanthranilates) (Endo et al., 2010, Biol. Pharm. Bull. 33:886-90); (b) a screen against COX-1 and COX-2 to reaffirm that compounds do not act as NSAIDs; and (c) an expanded screen against other nuclear receptors (especially other steroid hormone receptors).

Assay: Cell-based activity under Prompt Conditions: Cell-based activity under Prompt Conditions. Rat or human NHE3-mediated Na+-dependent H+ antiport was measured using a modification of the pH sensitive dye method originally reported by Paradiso (PNAS USA. 81:7436-7440, 1984). Opossum kidney (OK) cells were obtained from the ATCC and propagated per their instructions. The rat NHE3 gene (GenBank M85300) or the human NHE3 gene (GenBank NM_004174.1) was introduced into OK cells via electroporation, and cells were seeded into 96 well plates and grown overnight. Medium was aspirated from the wells, cells were washed twice with NaCl-HEPES buffer (100 mM NaCl, 50 mM HEPES, 10 mM glucose, 5 mM KCl, 2 mM CaCl2, 1 mM MgCl2, pH 7.4), then incubated for 30 min at room temperature with NH4Cl-HEPES buffer (20 mM NH4Cl, 80 mM NaCl, 50 mM HEPES, 5 mM KCl, 2 mM CaCl2, 1 mM MgCl2, pH 7.4) containing 5 μM bis(acetoxymethyl) 3,3′-(3′,6′-bis(acetoxymethoxy)-5-((acetoxymethoxy)carbonyl)-3-oxo-3H-spiro[isobenzofuran-1,9′-xanthene]-2′,7′-diyl)dipropanoate (BCECF-AM).Cells were washed twice with Ammonium free, Na+-free HEPES (100 mM choline, 50 mM HEPES, 10 mM glucose, 5 mM KCl, 2 mM CaCl2, 1 mM MgCl2, pH 7.4) and incubated in the same buffer for 10 minutes at room temperature to lower intracellular pH. NHE3-mediated recovery of neutral intracellular pH was initiated by addition of Na-HEPES buffer containing 0.4 μM ethyl isopropyl amiloride (EIPA, a selective antagonist of NHE-1 activity that does not inhibit NHE3) and 0-30 μM test compound, or a pharmaceutically acceptable salt thereof, and monitoring the pH sensitive changes in BCECF fluorescence (λex 505 nm, λem, 538 nm) normalized to the pH insensitive BCECF fluorescence (λex 439 nm, λem, 538 nm). Initial rates were plotted as the average 2 or more replicates, and pIC50 values were estimated using GraphPad Prism.

Assay: Competition Binding Assay: For the binding assays, streptavidin-coated magnetic beads were treated with biotinylated affinity ligands for 30 min at room temperature to generate affinity resins. The liganded beads were blocked with excess biotin and washed with blocking buffer (SeaBlock (Pierce), 1% BSA, 0.05% Tween 20, 1 mM DTT) to remove unbound ligand and to reduce non-specific binding. Binding reactions were assembled by combining kinase, liganded affinity beads, and test compounds in 1x binding buffer (20% SeaBlock, 0.17xPBS, 0.05% Tween 20, 6 mM DTT). Test compounds were prepared as 100x stocks in DMSO and rapidly diluted into the aqueous environment. DMSO was added to control assays lacking a test compound. Primary screen interactions were performed in polypropylene 384-well plates in a final volume of 34 uL, while Kd determinations were performed in polystyrene 96-well plates in a final volume of 135 uL. The assay plates were incubated at room temperature with shaking for 1 hr, long enough for binding reactions to reach equilibrium, and the affinity beads were washed extensively with wash buffer (1xPBS, 0.05% Tween 20) to remove unbound protein. The beads were then resuspended in elution buffer (1xPBS, 0.05% Tween 20, 2 uM non-biotinylated affinity ligand) and incubated at room temperature with shaking for 30 min. The kinase concentration in the eluates was measured by quantitative PCR. Each kinase was tested individually against each compound.

Assay: AlphaScreen Assay: In AlphaScreen, when the donor and acceptor beads are close in proximity, a series of photochemical events will give rise to a fluorescent signal upon light activation. Here we use biotinylated poly-(Glu, Tyr) 4:1 as the kinase substrate, streptavidin-coated donor beads and anti-phosphortyrosine antibody PY100-coated acceptor beads. Upon phosphorylation, the peptide substrate can bind to both donor and acceptor beads, thus gives rise to fluorescence. Compounds, ATP, biotinylated poly-(Glu, Tyr) and kinases are mixed in a volume of 20 μL for 1 hr at ambient temperature using Greiner 384-well white clear bottom medium binding plates. Then 10 uL solution containing 15-30 mg/mL AlphaScreen beads, 75 mM Hepes, pH 7.4, 300 mM NaCl, 120 mM EDTA, 0.3% BSA and 0.03% Tween-20 is added to each well. After 2-16 hr incubation of the beads, plates are read in a Perkin Elmer AlphaQuest reader (available from PerkinElmer Life and Analytical Sciences, Inc., of Boston Mass.).

Target: Serine/threonine-protein kinase pim-3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q86V86
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. A reference compound was included on each assay plate in order to validate that plate; on

Assay: cAMP Assay: Accumulation of intracellular cAMP was examined as a measure of the ability of the peptides of the present invention to elicit a functional response in a human melanoma cell line, HBL, that express hMCR-1 (see Kang, L., et al., A selective small molecule agonist of melanocortin-1 receptor inhibits lipopolysaccharide-induced cytokine accumulation and leukocyte infiltration in mice, J. Leuk. Biol. 80:897-904 (2006)) or HEK-293 cells that express hMCR-4. Confluent HBL cells that express hMCR-1 or HEK-293 cells that express recombinant hMCR-4 were detached from culture plates by incubation in enzyme-free cell dissociation buffer. Dispersed cells were suspended in Earle's Balanced Salt Solution containing 10 mM HEPES (pH 7.5), 1 mM MgCl2, 1 mM glutamine, 0.5% albumin and 0.3 mM 3-isobutyl-1-methyl-xanthine (IBMX), a phosphodiesterase inhibitor. The cells were plated in 96-well plates at a density of 0.4Ã¿105 cells per well for HBL cells and 0.5x105 cells per well for HEK-293 cells and pre-incubated for 10 minutes. Cells were exposed for 15 minutes at 37° C. to peptides of the present invention dissolved in DMSO (final DMSO concentration of 1%) at a concentration range of 0.05-5000 nM in a total assay volume of 200 uL. NDP-α-MSH was used as the reference agonist. cAMP levels were determined by an HTRF cAMP cell-based assay system from Cisbio Bioassays utilizing cryptate-labeled anti-cAMP and d2-labeled cAMP, with plates read on a Perkin-Elmer Victor plate reader at 665 and 620 nM. Data analysis was performed by nonlinear regression analysis with Graph-Pad Prism software.

Assay: ThermoFluor® Assay: ThermoFluor® experiments were carried out using instruments owned by Janssen Research and Discovery, L.L.C. through its acquisition of 3-Dimensional Pharmaceuticals, Inc. 1,8-ANS (Invitrogen) was used as a fluorescent dye. Protein and compound solutions are dispensed into black 384-well polypropylene PCR microplates (Abgene) and overlayed with silicone oil (1 μL, Fluka, type DC 200) to prevent evaporation. 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; >60D 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 (1x=46 mL) 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.
