Assay: In Vitro Assay: On day of the assay, 100 uL of 0.05% CHAPS (in deionized H2O) was added to all wells of the GFB Unifilter plate and allowed soak for 1 h. A wash buffer of 50 mM HEPES (pH 7.4), 150 mM NaCl, and 5 mM MgCl2 was prepared to wash the filter plate. To prepare an assay buffer, BSA was added to the wash buffer to reach 0.01% and DTT was added to reach 1 mM. For IC50 mode, 10 mM compound stocks were serially diluted in DMSO with DMSO to give 20x required final concentration in DMSO (15 uL compound+30 uL DMSO). The 20x compound stocks were diluted in DMSO with Assay Buffer 4-fold to reach 5x the final test concentration in 25% DMSO (10 uL compound+30 uL Assay Buffer). Solutions were mixed by aspiration several times with a pipette set on 50 uL volume. For the assay, 10 uL of 5x compound stock solutions in 25% DMSO were added to the assay plate in duplicate.

Assay: ELISA-Based Assay: Measurement of inhibition by compounds was performed using the HCV replicon system. Several different replicons encoding different HCV genotypes or mutations were used. In addition, potency measurements were made using different formats of the replicon assay, including different ways of measurements and different plating formats. See Jan M. Vrolijk et al., A replicons-based bioassay for the measurement of interferons in patients with chronic hepatitis C, 110 J. VIROLOGICAL METHODS 201 (2003); Steven S. Carroll et al., Inhibition of Hepatitis C Virus RNA Replication by 2'-Modified Nucleoside Analogs, 278(14) J. BIOLOGICAL CHEMISTRY 11979 (2003). However, the underlying principles are common to all of these determinations, and are outlined below.Stable neomycin phosphotransferase encoding replicons-harboring cell lines were used, so all cell lines were maintained under G418 selection prior to the assay. Potency was determined using a cell ELISA assay with an antibody to the replicons encoded NS3/4a protease. See Caterina Trozzi et al., In Vitro Selection and Characterization of Hepatitis C Virus Serine Protease Variants Resistant to an Active-Site Peptide Inhibitor, 77(6) J. Virol. 3669 (2003).

Target: Fatty acid synthase (SINGLE PROTEIN), Homo sapiens
UniProt: P49327
Assay: Biochemical Assay: The FASN enzyme was isolated from SKBr3 cells. SKBr3 is a human breast cancer cell-line with high levels of FASN expression. It is estimated that FASN comprises about 25% of the cytosolic proteins in this cell line. SKBr3 cells were homogenized in a dounce homogenizer then centrifuged for 15 minutes at 4° C. to remove particulate matter. The supernatant was then analyzed for protein content, diluted to the appropriate concentration, and used to measure FASN activity. The presence of FASN was confirmed by western blot analysis. A similar method for isolation of FASN from SKBr3 cells is described in Teresa, P. et al. (Clin. Cancer Res. 2009; 15(24), 7608-7615). FASN activity of the SKBr3 cell extract was determined by measuring either NADPH oxidation or the amount of thiol-containing coenzyme A (CoA) released during the fatty acid synthase reaction. The dye CPM (7-diethylamino-3-(4'-maleimidyl-phenyl)-4-methylcoumarin) contains a thiol reactive group that increases its fluorescence emission on reaction with the sulfhydryl group of CoA.

Fluo-4 NW dye mix (Molecular Probes, Inc., Eugene, Oreg., USA) was prepared in buffer (see manufacturer's instructions). Cell plates were removed from the 37° C. incubator, the media discarded and then 30 μL of dye was added to each well. Plates were placed in the 37° C., non-CO2 incubator for 30 minutes and then room temperature for 30 minutes. Two sets of drug plates were prepared: A) Mixtures of compound plus agonist were prepared as follows, in order to determine close response: BzATP: 11 point ½ log, diluted in buffer, starting from 1 mM. Testing compounds: 11 point ½ log, diluted in 2% DMSO buffer starting from 10 μM. B) Agonist only mixture was prepared with BzATP at a single concentration in buffer (concentration determined by dose response). Compound mixtures (A) were added to assay plates containing cells and placed at room temperature for 30 minutes, then BzATP (B) was added. Fluorescence was read using the Tetra FLIPR® (Molecular Devices, Inc., Sunnyvale, Calif., USA) and IC50 values were calculated by standard methods to determine antagonist activity.

UniProt: O60674
Assay: In Vitro JAK Kinase Assay: Compounds herein were tested for inhibitory activity of JAK targets according to the following in vitro assay described in Park et al., Analytical Biochemistry 1999, 269, 94-104. 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.).

UniProt: P34972
Assay: Binding Assay: The binding assays were performed by testing the ability of the new compounds to displace the radiolabeled synthetic non-selective cannabinoid agonist [3H]CP55940 (168 Ci/mmol; PerkinElmer) from the human CB1 (hCB1) or human CB2 (hCB2) receptors on membranes derived from stably transfected HEK-293 cells (PerkinElmer). Membranes were diluted in assay buffer (50 mM Tris-HCl, 1 mM EDTA, 1 mM MgCl2, 1 mg/ml BSA, pH=7.4). The amount of membrane was determined for each batch of membranes according to protein binding assay. The minimum amount of membrane that gave 50% specific binding was used for the binding assay. In most assays, binding was tested using 8 μg and 4 μg protein of hCB1 and hCB2 membranes, respectively. The tested compounds were dissolved in DMSO and diluted in assay buffer to a final concentration of 0.1% solvent. Total binding of [3H]CP55940 was evaluated with 1.5 nM to hCB1 and with 0.5 nM to hCB2, according to Kd affinity of [3H]CP55940 for the respective membranes. The ability of the tested compounds to displace [3H]CP55940 was evaluated first at a single concentration point of 100 nM for binding toward hCB2 or hCB1. In certain cases, the displacement was tested at compound concentrations ranging from 0.03 nM to 10 μM. Non-specific binding was measured by the addition of 1 μM of unlabelled CP55940 to the tubes. Binding assays were performed in triplicate in a total volume of 500 μl for 60 minutes at 30° C., in a shaking bath. Free and bound radioligands were separated by rapid filtration through GF/C filter plates (PerkinElmer) that had been presoaked with 0.1% Polyethylenimine (Sigma). Filters were shaken for 1 hour in 7 ml scintillation fluid (PerkinElmer) and radioactivity was determined by liquid scintillation counter (Wallac; PerkinElmer).

Assay: ADP Hunter Plus Assay: The kinase activity was measured by using the commercial ADP Hunter Plus assay available from DiscoveRx (#90-0083), which is a homogeneous assay to measure the accumulation of ADP, a universal product of kinase activity. The enzyme, DNA-PK was purchased from Promega (#V5811). The assay was done following the manufacturer recommendations with slight modifications: Mainly the kinase buffer was replace by 15 mM HEPES, pH 7.5, 10 mM MgCl2, 20 mM NaCl, 1 mM EGTA, 0.1 mg/mL BGG, 0.02% Tween 20. The DNA-PK was assayed in a titration experiment to determine the optimal protein concentration for the inhibition assay. To calculate the 1050 of the Compounds, serial 1:3 dilutions of the compounds were added to the enzyme at a fixed concentration (2 U/uL). The enzyme was preincubated with the inhibitor and 200 uM DNA substrate and then ATP was added to a final 75 uM concentration. Reaction was carried out for 1 hour at 37° C. Reagent A and B were sequentially added to the wells and plates were incubated for 30 min at RT. Fluorescence counts were read in a EnVision instrument (Perkin Elmer) with the recommended settings (550 and 590 nm as excitation and emission wavelengths, respectively). Values were normalized against the control activity included for each enzyme (i.e., 100% DNA_PK kinase activity, without compound). These values were plotted against the inhibitor concentration and were fit to a sigmoid dose-response curve by using the model sigmoidal Four-Parameter Logistc implement for Activity base - software.

Assay: ELISA-Based Assay: Measurement of inhibition by compounds was performed using the HCV replicon system. Several different replicons encoding different HCV genotypes or mutations were used. In addition, potency measurements were made using different formats of the replicon assay, including different ways of measurements and different plating formats. See Jan M. Vrolijk et al., A replicons-based bioassay for the measurement of interferons in patients with chronic hepatitis C, 110 J. VIROLOGICAL METHODS 201 (2003); Steven S. Carroll et al., Inhibition of Hepatitis C Virus RNA Replication by 2'-Modified Nucleoside Analogs, 278(14) J. BIOLOGICAL CHEMISTRY 11979 (2003). However, the underlying principles are common to all of these determinations, and are outlined below.Stable neomycin phosphotransferase encoding replicons-harboring cell lines were used, so all cell lines were maintained under G418 selection prior to the assay. Potency was determined using a cell ELISA assay with an antibody to the replicons encoded NS3/4a protease.

Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
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: 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: 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.
