Assay: PI3-Kinase HTRF Assay: A PI3-Kinase HTRF® assay kit (cat No. 33-016) purchased from Millipore Corporation is used to screen compounds provided herein. This assay uses specific, high affinity binding of the GRP1 pleckstrin homology (PH) domain to PIP3, the product of a Class 1A or 1B PI3 Kinase acting on its physiological substrate PIP2. During the detection phase of the assay, a complex is generated between the GST-tagged PH domain and biotinylated short chain PIP3. The biotinylated PIP3 and the GST-tagged PH domain recruited fluorophores (Streptavidin-Allophycocyanin and Europium-labeled anti-GST respectively) to form the fluorescence resonance energy transfer (FRET) architecture, generating a stable time-resolved FRET signal. The FRET complex is disrupted in a competitive manner by non-biotinylated PIP3, a product formed in the PI3 Kinase assay.PI3 Kinase α, γ or δ activity is assayed using the PI3 Kinase HTRF® assay kit (catalogue No. 33-016) purchased from Millipore Corporation. Purified recombinant PI3Kα (catalogue No. 14-602-K), PI3Kβ (catalogue No. 14-603-K), PI3Kγ (catalogue No. 14-558-K), and PI3Kδ (catalogue No. 14-604-K) are obtained from Millipore Corporation. Purified recombinant PI3K enzyme is used to catalyze the phosphorylation of phosphatidylinositol 4,5-bisphosphate (PIP2 at 10 μM) to phosphatidylinositol 3,4,5-trisphosphate (PIP3) in the presence of 10 μM ATP. The assay is carried out in 384-well format and detected using a Perkin Elmer EnVision Xcite Multilabel Reader. Emission ratios are converted into percent inhibitions and imported into GraphPad Prism software. The concentration necessary to achieve inhibition of enzyme activity by 50% (IC50) is calculated using concentrations ranging from 20 μM to 0.1 nM (12-point curve). IC50 values are determined using a nonlinear regression model available in GraphPad Prism 5.

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: 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.

Final concentration of DMSO in the reaction was 0.5% (v/v). Human TRPA1 expressing CHO cells were grown in F-12 DMEM medium with 10% FBS, 1% penicillin-streptomycin solution, and 400 ug/ml of G-418. Cells were seeded 24 h prior to the assay in 96 well plates so as to get 50,000 cells per well on the day of experiment. Cells were treated with test compounds for 10 min followed by addition of AITC at a final concentration of 30 micromolar and 5 uCi/ml 45Ca+2 for 3 min at 25° C. Cells were washed and lysed using buffer containing 1% Triton X-100, 0.1% deoxycholate and 0.1% SDS. Radioactivity in the lysate was measured in Packard Top count.

Assay: Biochemical Assay: The autoparsylation activity of the TNKS 1/2 or PARP1/2 enzymes was measured by the liquid chromatography-mass spectrometry (LC/MS) detection of nicotinamide as readout. Compound activity in inhibiting the TNKS and PARP autoparsylation was evaluated by IC50 measurements. In the compound screening assays, the reaction is composed of 5 μL of compound in 8-point serial dilutions with concentrations ranging from 0.0086 to 18.75 μM, 20 nM of purified enzyme, and 250 μM of β-NAD+ in the 1× Assay Buffer. After 60 min incubation at room temperature, the reactions were quenched by the addition of 10 μL of 5× quenching solution (20% formic acid and 500 nM [d]-nicotinamide in water). For the background control wells, 10 μL of the 5× quenching solution per well was added prior to the addition of β-NAD+.

Assay: In Vitro Raf Activity: Raf and biotinylated Mek, kinase dead, were combined at 2× final concentrations in assay buffer (50 mM Tris, pH 7.5, 15 mM MgCl2, 0.01% BSA and 1 mM DTT) and dispensed 5 ml per well in assay plates (Greiner white 384 well assay plates #781207) containing 0.25 ml of 40× of a Raf kinase inhibitor test compound diluted in 100% DMSO. The plate was incubated for 60 minutes at room temperature. The Raf kinase activity reaction was started by the addition of 5 mL per well of 2×ATP diluted in assay buffer. After 3 hours (b-Raf(V600E)) or 1 hour (c-Raf). The reactions were stopped and the phosphorylated product was measured using a rabbit anti-p-MEK (Cell Signaling, #9121) antibody and the Alpha Screen IgG (ProteinA) detection Kit (PerkinElmer #6760617R), by the addition of 10 mL to the well of a mixture of the antibody (1:2000 dilution) and detection beads (1:2000 dilution of both beads) in Stop/bead buffer (25 mM EDTA, 50 mM Tris, pH 7.5, 0.01% Tween20). The additions were carried out under dark conditions to protect the detection beads from light. A lid was placed on top of the plate and incubated for 1 hour at room temperature, then the luminescence was read on a PerkinElmer Envision instrument. The concentration of each compound for 50% inhibition (IC50) was calculated by non-linear regression using XL Fit data analysis software.

Assay: cytomteric bead array (CBA) assay: The Fix buffer I was warmed up to 37° C. in an incubator or water bath prior to use. The Perm Buffer III was chilled in a â¿¿20° C. freezer prior to use. The cells were collected at the end of treatment with testing compounds. One volume of the pre-warmed Fix Buffer I was mixed with one volume of cell suspension. If the volume of the cell suspension is greater than 100 uL, the cells were spun and resuspended in 100 uL medium or PBS. The buffer and the cell suspension were mixed well and incubated in a 37° C. water bath for 10 min. The cells were spun down at 250Ã¿g for 10 min and the supernatant was aspirated. The cells were washed once with BD Stain Buffer. The pellet was spun and the supernatant was removed. The cells were vortexed to be loosened, and permeabilized by slowly adding cold Perm Buffer III while vortexing or mixing. Subsequently, the cells were incubated on ice for 30 min. The cells were then spun down and washed twice with Stain Buffer. The supernatant was spun and aspirated. The cells were resuspended in a small volume of Stain buffer (50 or 100 uL containing from 200,000 to 1 million cells). Anti-IKFZ3 antibody was added to the cell suspension at 1:1000 dilution and incubated for 45 min at 4° C. The cells were then spun down and washed once with stain buffer. Secondary antibody was added to the cells at 1:5000 dilution and incubated at room temperature for 20 min in the dark. The cells were washed once with stain buffer prior to analysis by FACS.

Assay: Enzymatic IDO Assay: The IC50 values for each compound were determined by testing the activity of IDO in a mixture containing 50 mM potassium phosphate buffer at pH 6.5; 70 nM purified human IDO protein, 200 μM L-tryptophan, 20 mM ascorbate, 20 μM methylene blue, 0.1% DMSO. The inhibitors were initially diluted in DMSO at 100 mM and were diluted in potassium phosphate 50 mM, added to the reaction mixture at final concentrations raging from 1 mM to 5 nM and preincubated with the enzyme for 5 min at 25° C. The reaction was started by addition of L-tryptophan to 200 μM and incubated 15 min at 37° C. The reaction was stopped by addition of 0.5 vol of 30% trichloroacetic acid and incubated 30 min at 60° C. to hydrolyze N-formylkynurenine to kynurenine. The reaction was centrifuged at 3400 g for 5 min to remove precipitated protein and the supernatant was reacted with 2% (w/v) of p-dimethylaminobenzaldehyde in acetic acid. The reaction was incubated 10 min at 25° C. and read at 480 nm in a spectrophotometer. Control samples with no IDO inhibitor, or with no IDO enzyme or with the reference inhibitors 1-methyl-tryptophan (200 μM) and menadione (1.2 μM) were used as controls to set the parameters for the non-linear regressions necessary for determination of the IC50 for each compound. Nonlinear regressions and determination of the IC50 values were performed using the GraphPad Prism 4 software. Compounds with an IC50 of less than 500 μM were considered as active inhibitors in this assay.

Target: Tyrosine-protein kinase JAK1 (SINGLE PROTEIN), Homo sapiens
UniProt: P23458
Assay: In vitro JAK Kinase Assay: The catalytic domains of human JAK1 (a.a. 837-1142), Jak2 (a.a. 828-1132) and Jak3 (a.a. 781-1124) with an N-terminal His tag were expressed using baculovirus in insect cells and purified. The catalytic activity of JAK1, JAK2 or JAK3 was assayed by measuring the phosphorylation of a biotinylated peptide. The phosphorylated peptide was detected by homogenous time resolved fluorescence (HTRF). IC50s of compounds were measured for each kinase in the 40 microL reactions that contain the enzyme, ATP and 500 nM peptide in 50 mM Tris (pH 7.8) buffer with 100 mM NaCl, 5 mM DTT, and 0.1 mg/mL (0.01%) BSA. For the 1 mM IC50 measurements, ATP concentration in the reactions was 1 mM. Reactions were carried out at room temperature for 1 hr and then stopped with 20 μL 45 mM EDTA, 300 nM SA-APC, 6 nM Eu-Py20 in assay buffer (Perkin Elmer, Boston, Mass.). Binding to the Europium labeled antibody took place for 40 minutes and HTRF signal was measured on a Fusion plate reader (Perkin Elmer, Boston, Mass.)

Target: Sodium/hydrogen exchanger 3 (SINGLE PROTEIN), Homo sapiens
UniProt: P48764
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.
