Assay: Inhibitory Activity on Human ACC1 and the ACC2: Recombinant human ACC1 and recombinant human ACC2, which were prepared by the method mentioned above, were preincubated with assay buffer solution (50 mM HEPES-KOH (pH 7.4), 10 mM magnesium chloride, 6-10 mM potassium citrate, 4 mM reduced form of glutathione, 1.5 mg/ml bovine serum albumin) for one hour. Then, 0.2 μL of each this invention compound solution (in DMSO) were dispensed to 384-well microplate, 5 μL of the preincubated enzyme solution and 5 μL of substrate solution (50 mM HEPES-KOH (pH 7.4), 1 mM ATP, 0.8 mM acetyl CoA and 25-50 mM potassium bicarbonate) were added to microplate. After centrifugation and shaking, the reaction mixtures were incubated in a humidified box at room temperature for 1 to 3 hours. After the incubation, the enzyme reactions were stopped by the addition of EDTA. Then, after the samples were cocrystallized with CHCA (α-cyano-4-hydroxy cinnamic acid) matrices on MALDI target plate, by using the matrix assist laser deionization time-of-flight mass spectrometer (MALDI-TOF MS), samples were measured in reflector negative mode. Deprotonated ions of acetyl CoA (AcCoA) of substrate and malonyl CoA (MalCoA) of the reaction product were detected, then, the conversion rates of acetyl CoA to malonyl CoA was calculated by the intensity of [MalCoA-H]−/(Intensity of [MalCoA-H]−+Intensity of [AcCoA-H]−) using each signal strength. The 50% inhibitory concentration (IC50) was calculated from the inhibition rate of the enzymatic reaction at each concentration of the compounds. In addition, potassium citrate concentrations in assay buffer solution, potassium hydrogen carbonate concentrations in substrate solution and incubation time were adjusted by each lot of enzyme.

Assay: High Throughput Biochemical Assay: EGFR activity was measured using KinEASE (Cisbio), a time-resolved fluorescence resonance energy transfer (TR-FRET) immunoassay. In this assay, EGFR-catalyzes the phosphorylation of a universal Tyrosine kinase peptide substrate labeled with XL665. Europium conjugated phosphor-tyrosine specific antibody binds the resulting phosphorylated peptide. Formation of phosphorylated peptide is quantified by TR-FRET with Europium as the donor and XL665 the acceptor. The assay was performed in two main steps. The first step is the kinase reaction step and the second step is the detection step with TR-FRET reagents. In brief, test compounds 1:3 serially diluted in DMSO were delivered into Corning white, low volume, non-binding 384 well plates using the Echo 550 acoustic liquid dispenser (Labcyte®). EGFR enzyme (Human EGFR, cytoplasmic domain [669-1210] from Carna Biosciences Cat. No. 08-115) and substrates TK substrate-biotin (included in Cisbio HTRF KinEASE-TK kit Cat. No. 62TK0PEJ) were dispensed into assay plates using a Multi-Flo (Bio-Tek Instruments). The standard 10 μL reaction mixture contained 6 μM ATP (1×Km) or 12 μM ATP (2×Km), 1 μM biotinylated peptide, 0.3 nM EGFR (for 1×Km ATP) or 0.1 nM EGFR (for 2×Km ATP) in reaction buffer (10 mM MOPs, pH 7.0, 1.5% Glycerol, 0.5 mg/ml BSA, 10 mM Mg-Acetate, 1 mM DTT, 0.025% NP-40). After 60 min of incubation at room temperature, 10 μL of Stop and Detect Solution (1:400 Europium Cryptate labeled anti-phosphorylated peptide antibody solution and 125 nM strepavidin-XL665 Tracer in a 50 mM Hepes pH 7.0 detection buffer containing sufficient EDTA) was added. The plate was then further incubated for over 60 minutes at room temperature and read using an Envision 2103 Multilabeled reader (PerkinElmer) with excitation/emission/FRET emission at 340 nm/615 nm/665 nm, respectively.

Assay: V9103X ADP-Glo Kinase Assay Custom: In a 384-well plate, test compound diluted in assay buffer (1% DMSO final) is mixed with 8His-RIPK2 FL enzyme (final concentration of 8 nM). After 15 minutes of pre-incubation at RT, ATP dissolved in assay buffer is added (final concentration 5 μM). The mixture is incubated for 60 minutes at 37° C. in a humidified incubator. Then, ADP Glo Reagent is added, followed by a 40 minute incubation at rt. Finally, Kinase Detection Reagent is added and the entire mixture is incubated for 40 min at RT. The luminescence signal is measured with an Envision reader to determine the amount of ADP produced. Assay buffer: 25 mM HEPES (4-(2-hydroxyethyl)-1-piperazinethanesulfonic acid), 0.1% BSA (bovine serum albumin), 10 mM MgCl2, 5 mM MnCl2, 50 mM KCl, 0.01% CHAPS (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate), 10 μM Na3VO4, 1 mM DTT (dithiothreitol), pH 7.5 All plates contain wells with vehicle controls instead of compound (1% DMSO) as reference for the high signal (100% CTL (100% of control), high signal), and wells without enzyme as reference for low signal (0% CTL, low signal). The luminescent signal generated is proportional to the ADP produced and is correlated with enzyme activity. The analysis of the data is performed by the calculation of the percentage of ADP production in the presence of the test compound and RIPK2 as compared to the ADP production in the presence of RIPK2 plus 50 μM Gefitinib.

Assay: Serum Binding Analysis: In order to more properly assess the binding efficacy of the compounds, radioligand binding assays were carried out in the presence of 100% human serum to more accurately reflect the in vivo environment. While observed IC50 values are typically lower than those reported for buffer binding assays, the relevance of the assay for ranking of compound efficacy is enhanced. Target compounds were tested to determine their ability to bind with CXCR7 sites on MCF-7 and/or MDA-MB-435S CXCR7 transfected cells. Efficiency-maxim/zed radioligand binding using filtration protocols as described in Dairaghi D J, et al., HHV8-encoded vMIP-I selectively engages chemokine receptor CCR5. Agonist and antagonist profiles of viral chemokines., J. Biol. Chem. 1999 Jul. 30; 274(31): 21569-74 and Gosling J, et al., Cutting edge: identification of a novel chemokine receptor that binds dendritic cell- and T cell-active chemokines including ELC, SLC, and TECK, J. Immunol. 2000 Mar. 15; 164(6):2851-6 was used.In these assays, MCF-7 and/or MDA-MB-435S cells were interrogated with the target compounds and the ability of these compounds to displace 125 I radiolabeled SDF-1 was assessed using the protocol described in Dairaghi and Gosling. The target compounds were added to the plate to the indicated concentration followed by addition of cells and radiolabeled chemokine (125I SDF-1), both in the following medium (human AB serum with 10 mM HEPES added to stabilize at pH 7.4). All assays were then incubated for 3 hrs at 4° C. with gentle agitation. Following incubation in all binding assays, reactions were aspirated onto PEI-treated GF/B glass filters (Packard) using a cell harvester (Packard) and washed twice (25 mM HEPES, 500 mM NaCl, 1 mM CaCl2, 5 mM MgCl2, adjusted to pH 7.1). Scintillant (MicroScint 10, Packard) was added to the wells, and the filters were counted in a Packard Topcount scintillation counter. Data were analyzed and plotted using GraphPad Prism (GraphPad Software).

Target: Nuclear receptor ROR-gamma (SINGLE PROTEIN), Homo sapiens
UniProt: P51449
Assay: Biological Assay: The compounds of the invention inhibit RORgammaT activity. Activation of RORgammaT activity can be measured using, e.g., a biochemical TR-FRET assay. In such an assay, interaction of cofactor-derived peptides with human RORgammaT-Ligand Binding Domain (LBD) can be measured. The TR-FRET technique is a sensitive biochemical proximity assay that will give information concerning the interaction of a ligand with the LBD, in the presence of cofactor-derived peptides (Zhou et al., Methods 25:54-61, 2001).To identify novel antagonists of RORgammaT, an assay was developed which employs the interaction of RORgammaT with its co-activator peptide SRC1_2. This peptide mimics the recruitment of co-activators to RORgammaT through its interaction with the LXXLL (SEQ ID NO:1) (e.g., NR box) motifs (Xie et al., J. Immunol. 175: 3800-09, 2005; Kurebayashi et al., Biochem. Biophys. Res. Commun. 315: 919-27, 2004; Jin et al., Mol. Endocrinology 24:923-29, 2010). The RORγ-Ligand Binding Domain TR-FRET Assay was run according to the following protocol.

Assay: Inhibitory Activity Assay: The conditions for measuring inhibitory activity of compounds against LSD1 activity were determined with reference to a document available from the website of PerkinElmer (U-TRF #38) and a patent of GlaxoSmithKline (WO2012135113).To measure the inhibitory activity, first, the compound of the present invention was serially diluted in dimethylsulfoxide (DMSO). Sequentially, the solution of the compound of the present invention in DMSO (final concentration of DMSO: 5%) and human LSD1 protein (Abcam, ab80379) were added to a reaction buffer (25 mM Tris-HCl (pH 7.5), 50 mM KCl, 2 mM CHAPS, 1 mM DTT, 0.02% BSA). The mixture was preincubated at 25° C. for 30 minutes. Thereafter, a H3K4 (Me1)-biotin-labeled peptide (Anaspec #64355) (final concentration: 200 nM) was added thereto and reacted for 60 minutes. Tranylcypromine (final concentration: 3 mM) was then added thereto to terminate the reaction. Thereafter, a detection solution containing an Eu-labeled anti-H3K4 antibody (PerkinElmer, TRF0404) and Streptavidin Alexa Fluor 647 (Thermo Fisher Scientific, 521374) was added thereto, and the mixture was allowed to stand at room temperature for 1 hour. Finally, the intensity of fluorescence under the excitation light with a wavelength of 337 nm was measured with a PHERAstar FS (BMG Labtech) at two wavelengths: 620 nm and 665 nm. The demethylation level was calculated from the ratio of the fluorescence intensity at the two wavelengths, and the compound concentration at which demethylation was inhibited by 50% was defined as IC50 (nM).

Assay: Radioligand Binding Assay: Radioligand binding assays for Sigma-1 receptors and Sigma-2 receptors were carried out by a commercial contract research organization. For Sigma-1 binding, various concentrations of test compounds from 100 μM to 1 nM were used to displace 8 nM [3H](+)pentazocine from endogenous receptors on Jurkat cell membranes (Ganapathy M E et al. 1991, J Pharmacol. Exp. Ther. 289:251-260). 10 μM Haloperidol was used to define non-specific binding. For Sigma-2 receptors various concentrations of test compounds from 100 μM to 1 nM were used to displace 5 nM [3H] 1,3-Di-(2-tolyl)guanidine from endogenous receptors on membranes from rat cerebral cortex in the presence of 300 nM (+)pentazocine to mask Sigma-1 receptors. (Bowen W D, et al. 1993, Mol. Neuropharmcol 3:117-126). 10 μM Haloperidol was used to define non-specific binding. Reactions were terminated by rapid filtration through Whatman GF/C filters using a Brandel 12R cell harvester followed by two washes with ice-cold buffer. Radioactivity on the dried filter discs was measured using a liquid scintillation analyzer (Tri-Carb 2900TR; PerkinElmer Life and Analytical Sciences). The displacement curves were plotted and the Ki values of the test ligands for the receptor subtypes were determined using GraphPad Prism (GraphPad Software Inc., San Diego, Calif.). The percentage specific binding was determined by dividing the difference between total bound (disintegrations per minute) and nonspecific bound (disintegrations per minute) by the total bound (disintegrations per minute).

Assay: TLR7/8/9 Inhibition Reporter Assays: HEK-Blue-cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors were used for screening inhibitors of these receptors using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of the IFN-β minimal promoter fused to five NF-κB and AP-1-binding sites. 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.

Assay: BINDING ASSAY: The following assay can be used for determination of GPR43 activation. When a GPCR is in its active state, either as a result of ligand binding or constitutive activation, the receptor couples to a G protein and stimulates the release of GDP and subsequent binding of GTP to the G protein. The alpha subunit of the G protein-receptor complex acts as a GTPase and slowly hydrolyses the GTP to GDP, at which point the receptor normally is deactivated. Activated receptors continue to exchange GDP for GTP. The non-hydrolysable GTP analog, [35S]GTPγS, was used to demonstrate enhance binding of [35S]GTPγS to membranes expressing receptors. The assay uses the ability of GPCR to stimulate [35S]GTPγS binding to membranes expressing the relevant receptors. The assay can, therefore, be used in the direct identification method to screen candidate compounds to endogenous or not endogenous GPCR.

Assay: Enzymatic Activity Assay: The compounds were tested for serum and glucocorticoid-regulated kinase 1 (SGK-1) inhibitory activity in a substrate phosphorylation assay designed to measure the ability of the isolated enzyme to catalyze the transfer of phosphate from ATP to serine/threonine residues in a fluorescein-labeled substrate peptide, using recombinant human SGK-1 enzyme produced in a baculovirus system (Biomol, Hamburg, Germany, Cat. No. 4-331). The synthesized fluorescent labeled peptide substrate contained (5(6)-Carboxyfluorescein)-RPRAATF-NH2. The phosphorylated substrate peptide and non-phosphorylated substrate peptide were separated with caliper life science's lab-chip technology based on a micro fluidics method. All fluid flow was established on the chip by applying a vacuum of a few psi to the waste well transporting fluid from various sources through interconnecting channels. Because the phosphoryl group is doubly negatively charged, under the pressure-driven hydrodynamic flow and the voltage-driven flow within the electric field, the fluorescent labeled peptide substrate and its phosphorylation product appear at different times in the detection window to the detection point. Substrate turnover can thus be determined as the ratio of the product peak area and the sum of substrate peak area and product peak area.The enzyme reaction was carried out in a buffer containing 25 mM Tris-HCl (pH 7.4), 5 mM MgCl2, 2 mM MnCl2, 2 mM DTT, and 0.03% bovine serum albumine. The enzyme was pre-incubated with the test compound for 30 min at 24° C. The kinase reaction was initiated by addition of the substrate mixture containing the peptide substrate (final concentration 1 μM) and ATP (final concentration 10 μM). After 60 min incubation at 37° C., the enzyme reaction was terminated by adding a buffer containing 100 mM Hepes (pH 7.4) and 35 mM EDTA.

Assay: BACE1 HTRF FRET Assay: A homogeneous time-resolved FRET assay can be used to determine IC50 values for inhibitors of the soluble human BACE1 catalytic domain. This assay monitors the increase of 620 nm fluorescence that resulted from BACE1 cleavage of an APPswedish APPswe mutant peptide FRET substrate (QSY7-EISEVNLDAEFC-Europium-amide). This substrate contains an N-terminal QSY7 moiety that serves as a quencher of the C-terminal Europium fluorophore (620 nm Em). In the absence of enzyme activity, 620 nm fluorescence is low in the assay and increased linearly over 3 hours in the presence of uninhibited BACE1 enzyme. Inhibition of BACE1 cleavage of the QSY7-APPswe-Eu substrate by inhibitors is manifested as a suppression of 620 nm fluorescence.Varying concentrations of inhibitors at 3Ã¿ the final desired concentration in a volume of 10 ul are preincubated with purified human BACE1 catalytic domain (3 nM in 10 ul) for 30 minutes at 30° C. in reaction buffer containing 20 mM Na-Acetate pH 5.0, 10% glycerol, 0.1% Brij-35 and 7.5% DSMO. Reactions are initiated by addition of 10 ul of 600 nM QSY7-APPswe-Eu substrate (200 nM final) to give a final reaction volume of 30 ul in a 384 well Nunc HTRF plate. The reactions are incubated at 30° C. for 1.5 hours. The 620 nm fluorescence is then read on a Rubystar HTRF plate reader (BMG Labtechnologies) using a 50 millisecond delay followed by a 400 millisecond acquisition time window. Inhibitor IC50 values are derived from non-linear regression analysis of concentration response curves. Ki values are then calculated from IC50 values using the Cheng-Prusoff equation using a previously determined um value of 8 uM for the QSY7-APPswe-Eu substrate at BACE1. The compounds of Examples 1, 2, and 3 were measured in this assay and each exhibited a Ki value of less than about 5 nM.

Assay: In Vitro c-Met Kinase Enzyme Assay: Compounds were screened in vitro for their ability to inhibit c-Met kinase activity. The IC50 values of compounds for the inhibition of c-Met kinase were determined as described in the literature with some modifications (Wang, X. et al, Mol. Cancer Ther. 2003, 2(11):1085-1092; Calic, M. et al., Croatica Chemical ACTA. 2005, 78(3):367-374). Briefly, histidine-tagged c-Met catalytic domain fusion protein (Invitrogen, #PV3143) was used for the assay. IC50 measurements were based on the degree of phosphorylation of poly Glu-Tyr (Sigma-Aldrich, #P0275) that was coated (0.01 mg/per well) on 96-well microplates (R&D systems, #DY990). The reaction was carried out in a 50 μL solution containing 50 mM HEPES (pH 7.5), 10 mM MnCl2, 10 mM MgCl2, 0.5 mM DTT, 100 μM Na3VO4, 5 μM ATP (Cell Signaling Technology, #9804) and serial dilutions of individual compounds. The reaction lasted for 25 minutes at 30° C. After the reaction was completed, the contents of the plates was discarded. Plates were then washed with TBS-T (250 μL/well, 5×) and then blocked with TBS-T containing 1% BSA for 2 hours. The contents of the plates was discarded, and 100 μL (per well) of peroxidase-labeled anti-phospho-tyrosine antibody (Sigma, #A5964) diluted (1:60,000) in 1% BSA containing TBS-T were then added and incubated for 1 hour. Plates were washed with TBS-T (250 mL/well, 5×) and followed by the color reaction using 100 μL (1:1 mixture) of H2O2 and tetramethylbenzidine (R&D Systems, #DY999). The reaction was stopped in minutes with 100 μL of 2 N H2SO4. The optical density was measured immediately using a microplate reader at 450 nm with wavelength correction at 540 nm. IC50 values were calculated with the GraphPad Prism software. The linear range (i.e., the time period over which the rate remained equivalent to the initial rate) was determined for the kinase and IC50 determinations were performed within this range.
