Assay: OPR Mu Antagonist Assay: The purpose of this assay is to confirm the potency and selectivity of compounds synthesized to be OPRK1 Antagonists. This assay monitors the OPRMu1 activation, in membrane recruitment of β-arrestin. The assay monitors GPCR-β-arrestin proximity using low affinity fragment complementation of beta-galactosidase (beta-gal). It employs U20S cells which express OPRMu1 fused to the complementary beta-gal fragment (enzyme acceptor). As designed, compounds that act as antagonists will prevent receptor activation resulting in reduce well luminescence. Compounds were tested in triplicate using a 10-point, 1:3 dilution series starting at a nominal concentration of 10 micromolar.The Discover X OPRMu1-U20S cell line was routinely cultured in T175 flasks at 37° C., 5% CO2 and 95% relative humidity (RH). The growth media consisted of DMEM/F12 1:1 Media supplemented with 10% v/v heat inactivated fetal bovine serum, 25 mM HEPES, Non-essential amino acids, 1 mM Sodium Pyruvate, 1× antibiotic mix (penicillin streptomycin) plus 500 ug/mL Geneticin and 300 ug/mL Hygromycin (selection antibiotics).On Day 1 of the assay, 5000 cells in 20 ul of assay buffer (Discover X's Cell Plating Reagent 5) were seeded into each well of a 384 Corning 3570 standard white plate, and incubated 16-24 hours at 37° C., 5% CO2 and 95% (RH). On Day 2, 100 nl of test compound in DMSO was added to the appropriate wells, 100 nl of DMSO added to control wells and plates were incubated for 30 min at 37° C., 5% CO2 and 95% (RH). Next 100 nl of DAMGO OPRMu1 or DMSO in assay media (EC80 Challenge consists of 100 nl of 50 uM DAMGO, final assay concentration=250 nM, 100% Response wells receive 100 nl 200 uM DAMGO). After incubation for 3 hours at 37° C., 5% CO2 and 95% (RH), 10 ul of Path Hunter Detection Mix is added to each well, plate placed on a plate rotator/mixer for 10 minutes and then incubated at room temperature, in the dark for 1 hour. Well luminescence was measured on Perkin Elmer's Envision.The Percent Inhibition was calculated from the median ratio as follows:% ⁢ ⁢ Inhibition = 100 - ( 1 ⁢ 0 ⁢ 0 ⁢ ( Compound ⁢ ⁢ Well - 0 ⁢ % ⁢ ⁢ Response ⁢ ⁢ Well EC ⁢ ⁢ 80 ⁢ ⁢ Control ⁢ ⁢ Well - 0 ⁢ % ⁢ ⁢ Response ⁢ ⁢ Well ) )where:    COMPOUND WELL is defined as the well containing test compound;    EC80 CONTROL WELL is defined as wells containing DAMGO challenge (250 nM final)=0% inhibition; and    0% RESPONSE WELL is defined as wells containing DMSO=100% inhibition.IC50 is defined as the concentration of compound required to achieve 50% inhibition.

Assay: Inhibition Assay of PI3K: An exemplary system is PI 3-Kinase (human) HTRF Assay from Upstate. The assay can be carried out according to the procedures suggested by the manufacturer. Briefly, the assay is a time resolved FRET assay that indirectly measures PIP3 product formed by the activity of a PI3-K. The kinase reaction is performed in a microtitre plate (e.g., a 384 well microtitre plate). The total reaction volume is approximately 20 ul per well. In the first step, each well receives 2 ul of test compound in 20% dimethylsulphoxide resulting in a 2% DMSO final concentration. Next, approximately 14.5 ul of a kinase/PIP2 mixture (diluted in 1× reaction buffer) is added per well for a final concentration of 0.25-0.3 ug/ml kinase and 10 μM PIP2. The plate is sealed and incubated for 15 minutes at room temperature. To start the reaction, 3.5 ul of ATP (diluted in 1× reaction buffer) is added per well for a final concentration of 10 μM ATP. The plate is sealed and incubated for 1 hour at room temperature. The reaction is stopped by adding 5 ul of Stop Solution per well and then 5 ul of Detection Mix is added per well. The plate is sealed, incubated for 1 hour at room temperature, and then read on an appropriate plate reader.

Assay: Monoamine Oxidase Assays for Determining the Selectivity of the Compounds of the Invention for LSD1: Human recombinant monoamine oxidase proteins MAO-A and MAO-B were purchased from Sigma Aldrich. MAOs catalyze the oxidative deamination of primary, secondary and tertiary amines. In order to monitor MAO enzymatic activities and/or their inhibition rate by inhibitor(s) of interest, a fluorescent-based (inhibitor)-screening assay was set up. 3-(2-Aminophenyl)-3-oxopropanamine (kynuramine dihydrobromide, Sigma Aldrich), a non fluorescent compound was chosen as a substrate. Kynuramine is a non-specific substrate for both MAOs activities. While undergoing oxidative deamination by MAO activities, kynuramine is converted into 4-hydroxyquinoline (4-HQ), a resulting fluorescent product.The monoamine oxidase activity was estimated by measuring the conversion of kynuramine into 4-hydroxyquinoline. Assays were conducted in 96-well black plates with clear bottom (Corning) in a final volume of 100 μL. The assay buffer was 100 mM HEPES, pH 7.5. Each experiment was performed in triplicate within the same experiment.Briefly, a fixed amount of MAO (0.25 μg for MAO-A and 0.5 μg for MAO-B) was incubated on ice for 15 minutes in the reaction buffer, in the absence and/or in the presence of various concentrations of inhibitor (e.g., from 0 to 50 μM, depending on the inhibitor strength). Tranylcypromine (Biomol International) was used as a control for inhibition.After leaving the enzyme(s) interacting with the inhibitor, 60 to 90 μM of kynuramine was added to each reaction for MAO-B and MAO-A assay respectively, and the reaction was left for 1 hour at 37° C. in the dark. The oxidative deamination of the substrate was stopped by adding 50 μL (v/v) of NaOH 2N. The conversion of kynuramine to 4-hydroxyquinoline, was monitored by fluorescence (excitation at 320 nm, emission at 360 nm) using a microplate reader (Infinite 200, Tecan). Arbitrary units were used to measure levels of fluorescence produced in the absence and/or in the presence of inhibitor.The maximum of oxidative deamination activity was obtained by measuring the amount of 4-hydroxyquinoline formed from kynuramine deamination in the absence of inhibitor and corrected for background fluorescence in the absence of MAO enzymes.

Assay: In Vitro DGK Inhibition Assay: The reactions were carried out in 50 mM MOPS pH 7.5, 100 mM NaCl, 10 mM MgCl2, 1 μM CaCl2, and 1 mM DTT (assay buffer). The reactions using a detergent/lipid micelle substrate also contained 50 mM octyl B-D-glucopyranoside. The lipid substrate concentrations were 11 mM PS and 1 mM DAG for the detergent/lipid micelle reactions. The lipid substrate concentrations were 2 mM PS, 0.25 mM DAG, and 2.75 mM PC for the extruded liposome reactions (5 mM total lipid). The reactions were carried out in 150 μM ATP. The enzyme concentrations for the DGKα and DGKζ were 5 nM. The compound inhibition studies were carried out as follows: 25 nL (ADPGLO assay) or 50 nL (LIPGLO assay) droplets of each test compound (top concentration 10 mM with 11 point, 3-fold dilution series for each compound) solubilized in DMSO were transferred to wells of a white 1536 well plate (Corning 3725). A 5 mL enzyme/lipid substrate solution at 2× final reaction concentration was prepared by combining 2.5 mL 4× enzyme solution (20 nM DGKα or DGKζ (prepared as described below) in assay buffer) and 2.5 mL of either 4× liposome or 4× detergent/lipid micelle solution (compositions described below) and incubated at room temperature for 10 minutes. Next, 1 μL 2× enzyme/lipid substrate solution was added to wells containing the test compound and reactions were initiated with the addition of 1 μL 300 uM ATP. The reactions were allowed to proceed for 2 hr (ADPGLO assay) or 1 hr (LIPGLO assay), after which 2 μL Glo Reagent (Promega V9101) was added and incubated for 40 minutes. Next, 4 μL Kinase Detection Reagent was added and incubated for 30 minutes. Luminescence was recorded using an EnVision microplate reader. The percent inhibition was calculated from the ATP conversion generated by no enzyme control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition.

Assay: PI3K-gamma Selective Assay: A compound's ability in selectively inhibiting PI3K-γ can be assessed using RAW264.7 macrophages. Briefly, serum-starved RAW264.7 cells are stimulated with a known GPCR agonist C5a. See, e.g., Camps et al., Nature Medicine (2005) 11(9):936-943. Cells can be treated with test compounds prior to, simultaneously with, or subsequent to the stimulation by C5a. RAW 264.7 cells respond to the complement component fragment C5a through activation of the C5a receptor, and the C5a receptor activates macrophages and induces cell migration. Test compounds' ability to inhibit C5a-mediated AKT phosphorylation is indicative of selective inhibition of PI3K-γ. Thus, by monitoring the reduction of phospho-AKT in stimulated RAW 264.7 cells (using for example, phospho-AKT antibodies), a compound's potential efficacy in selectively inhibiting PI3Kγ can be assessed.

Assay: IMAP (Immobilized Metal Ion Affinity-Based Fluorescence Polarization) Assay: TXK enzyme activity is measured using the IMAP (immobilized metal ion affinity-based fluorescence polarization) assay as outlined below.TXK enzyme (Millipore #14-761), is diluted to 2.5 U/mL in KR buffer (10 mM Tris-HCl, 10 mM MgCl2, 0.01% Tween-20, 0.1% NaN3, 1 mM DTT, 2 mM MnCl2, pH 7.5).Serial dilutions log 10 from 2 mM to 63.2 nM of test compounds are made in 100% DMSO. The dilutions in DMSO are then diluted 50-fold in KR-buffer. Final compound concentration range in the assay ranged from 10 μM to 0.316 nM.The assay is performed as follows: 5 μL/well of test compound in KR buffer (final DMSO concentration in the assay is 1%) is mixed with 5 μL/well of 2.5 U/mL TXK enzyme (final concentration in the assay is 0.625 U/mL (4.4 nM)). Test compounds and TXK enzyme are pre-incubated 60 minutes at room temperature, before adding 5 μL/well of 200 nM Fluorescin labeled substrate peptide (Blk/Lyntide substrate #R7188, Molecular Devices) in KR-buffer. Final peptide substrate concentration in assay is 50 nM. The kinase assay is started by adding 5 μL/well of 4 μM ATP in KR-buffer (final ATP concentration is 1 μM ATP, Km ATP in TXK IMAP assay). Following incubation for 2 hours at room temperature the enzyme reaction is stopped by adding 40 μL/well IMAP Progressive Binding Solution (according to suppliers (Molecular Devices) protocol using 60% 1× buffer A and 40% 1× buffer B with 800× diluted beads (Progressive Binding System, Molecular Devices). After 60 min incubation at room temperature in the dark the FP signal is read. Fluorescence at 535 nm is measured using parallel and perpendicular filters to determine differences in rotation due to binding of the phosphorylated substrate peptide to the beads.

Briefly, cells are seeded into Greiner 384 well plates (15000 cells per well for TLR7, 20,000 for TLR8 and 25,000 for TLR9) and then treated with test compounds in DMSO to yield a final dose response concentration range of 0.05 nM-50 μM. After a 30 minute compound pre-treatment at room temperature, the cells are then stimulated with a TLR7 ligand (gardiquimod at a final concentration of 7.5 μM), TLR8 ligand (R848 at a final concentration of 15.9 μM) or TLR9 ligand (ODN2006 at a final concentration of 5 nM) to activate NF-κB and AP-1 which induce the production of SEAP. After a 22 hour incubation at 37° C., 5% CO2, SEAP levels are determined with the addition of HEK-Blue Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications. The percent inhibition is determined as the % reduction in the HEK-Blue signal present in wells treated with agonist plus DMSO alone compared to wells treated with a known inhibitor.
