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.

Target: Lysine-specific histone demethylase 1A (SINGLE PROTEIN), Homo sapiens
UniProt: O60341
Assay: Biological Assay: The compounds of the invention can be tested for their ability to inhibit LSD1. The ability of the compounds of the invention to inhibit LSD1 can be tested as follows. Human recombinant LSD1 protein was purchased from BPS Bioscience Inc (catalog reference number 50100: human recombinant LSD1, GenBank accession no. NM_015013, amino acids 158-end with N-terminal GST tag, MW: 103 kDa). In order to monitor LSD1 enzymatic activity and/or its inhibition rate by our inhibitor(s) of interest, di-methylated H3-K4 peptide (Anaspec) was chosen as a substrate. The demethylase activity was estimated, under aerobic conditions, by measuring the release of H2O2 produced during the catalytic process, using the Amplex Red hydrogen peroxide/peroxidase assay kit (Invitrogen).Briefly, a fixed amount of LSD1 was incubated on ice for 15 minutes, in the absence and/or in the presence of at least eight 3-fold serial dilutions of the respective inhibitor (e.g., from 0 to 75 uM, depending on the inhibitor strength). Tranylcypromine (Biomol International) was used as a control for inhibition. Within the experiment, each concentration of inhibitor was tested in duplicate. After leaving the enzyme interacting with the inhibitor, KM of di-methylated H3-K4 peptide was added to each reaction and the experiment was left for 30 minutes at 37° C. in the dark. The enzymatic reactions were set up in a 50 mM sodium phosphate, pH 7.4 buffer. At the end of the incubation, Amplex Red reagent and horseradish peroxidase (HPR) solution were added to the reaction according to the recommendations provided by the supplier (Invitrogen), and left to incubate for 5 extra minutes at room temperature in the dark. A 1 uM H2O2 solution was used as a control of the kit efficiency. The conversion of the Amplex Red reagent to resorufin due to the presence of H2O2 in the assay, was monitored by fluorescence (excitation at 540 nm, emission at 590 nm) using a microplate reader (Infinite 200, Tecan). Arbitrary units were used to measure level of H2O2 produced in the absence and/or in the presence of inhibitor. The maximum demethylase activity of LSD1 was obtained in the absence of inhibitor and corrected for background fluorescence in the absence of LSD1. The IC50 value of each inhibitor was calculated with GraphPad Prism Software.

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.

Assay: Homogeneous Time Resolved Fluorescence Assay: The ability of the compounds of the present invention to inhibit the activity of four PI3K isoforms, PI3Kα, PI3Kβ, PI3Kγ, and PI3Kδ, were determined using a commercially available lipid kinase assay run in Homogeneous Time Resolved Fluorescence (HTRF) format. Assay DescriptionAssay principle: The PIP3 product is detected by displacement of biotin-PIP3 from an energy transfer complex consisting of Europium labeled anti-GST monoclonal antibody, a GST-tagged pleckstrin homology (PH) domain, biotinylated PIP3 and Streptavidin-Allophycocyanin (APC). Excitation of Europium in the complex results in an energy transfer to the APC and a fluorescent emission at 665 nm. The PIP3 product formed by PI 3-Kinase(h) activity displaces biotin-PIP3 from the complex resulting in a loss of energy transfer and thus a decrease in signal.This is a 3-step reaction: First, the kinase reaction with PIP2 substrate is carried out in the presence of ATP, and the reaction is quenched.

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.).

Assay: Functional Assay: The assay was performed as described below, using HEK293 cells transfected with rat TRPV1 (rTRPV1/HEK293). These cells had a geneticin selection marker and were grown in Dulbecco's Modified Eagle Medium (DMEM, Gibco BRL) supplemented with 10% fetal bovine serum, penicillin/streptomycin (50 units/mL), and 500 μg/mL geneticin in 5% CO2 at 37° C. Cells were passaged frequently, every 3-5 days, to avoid overgrowth, depletion of essential medium components, or acidic medium exposure. Cells were passaged using a brief wash in 0.05% trypsin with 1 mM EDTA, followed by dissociation in divalent-free phosphate-buffered saline (Hyclone #SH30028.02). Dissociated cells were seeded onto poly-D-lysine coated black-walled 96-well plates (Biocoat; Becton Dickinson #354640) at about 40,000 cells per well and grown for approximately 1 day in culture medium to near confluency. The assay buffer was composed of 130 mM NaCl, 2 mM KCl, 2 mM MgCl2, 10 mM HEPES, 5 mM glucose, and either 2 mM or 20 μM CaCl2. On the day of the experiment, the culture medium was replaced with 2 mM calcium assay buffer using an automated plate washer (ELx405; Biotek, VT). The cells were incubated in 100 μL/well Fluo-3/AM (2 μM; TEFLabs #0116) with Pluronic F127 (100 μg/mL; Sigma #P2443) for 1 h at rt in the dark. After loading the cells, the dye solution was replaced with 50 μL/well of 20 μM calcium assay buffer using the ELx405 plate washer. Test compounds (50 μL/well) were added to the plate and incubated for 30 min. Intracellular Ca2+ levels were subsequently assayed using a Fluorometric Imaging Plate Reader (FLIPR™ instrument, Molecular Devices, CA) to simultaneously monitor Fluo-3 fluorescence in all wells (λexcitation=488 nm, λemission=540 nm) during challenge with agonist (capsaicin). The IC50 values were determined. Cells were challenged with 150 nM capsaicin and the fluorescence counts were captured following agonist addition at a sampling rate of 0.33 Hz. The contents of the wells were mixed 3 times (40 μL mix volume) immediately after the additions were made. Concentration dependence of block was determined by exposing each well of cells in duplicate rows of a 96 well plate to a serial dilution of test compound. The concentration series usually started at 10 Î¼M with a three-fold serial decrement in concentration. The magnitude of the capsaicin response was determined by measuring the change in fluo3 fluorescence before and 100 seconds after the addition of the agonist.

UniProt: Q9UBN7
Assay: Enzyme Assay: Enzyme activity of HDAC1,3 is determined using the substrate Ac-Lys-Tyr-Lys(Ac)-AMC while the enzyme activity of HDAC6 is assayed using the substrate Boc-lys(Ac)-AMC. The reaction is carried out in flat-bottom, 96-well, or 384-well microplates. After the substrate was deacetylated by HDACs, the product AMC which was obtained from hydrolysis by trypsin can generate fluorescence signal. Measurement is taken in using an multilabe plate reader a 355 nm excitation filter and a 460 nm emission filter. The initial rate of fluorescence should accurately reflect the rate of product formation and enzyme activity. Sample processing: The sample was dissolved in DMSO and kept at a low temperature. DMSO in the final system is limited under a low concentration which won't affect the enzyme activity.

Target: Tyrosine-protein kinase JAK3 (SINGLE PROTEIN), Homo sapiens
UniProt: P52333
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.

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.)
