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: 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.

Compound dilutions were made in 100% DMSO (VWR Chemicals 23500.297) in a polypropylene plate in 3-fold dilution steps to give a final concentration range in the assay from 25 μM to 1.7 nM. 1 μL compound dilutions (100% DMSO) were added to 19 μL MAGL (recombinant wild-type) in assay buffer (50 mM TRIS (GIBCO, 15567-027), 1 mM EDTA (Fluka, 03690-100 ml)). The plate was shaked for 1 min at 2000 rpm (Variomag Teleshake) and then incubated for 15 min at RT. To start the reaction, 20 μL 4-Nitrophenlyacetate (Sigma N-8130) in assay buffer with 6% EtOH was added. The final concentrations in the assay were 1 nM MAGL and 300 μM 4-Nitrophenylacetate. After shaking (1 min, 2000 rpm) and 5 min incubation at RT, the absorbance at 405 nm was measured for a fist time (Molecular Devices, SpectraMax Paradigm). A second measurement was then done after incubation for 80 min at RT. From the two measurements, the slope was calculated by subtracting the first from the second measurement.

Target: Estrogen receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P03372
Assay: Estrogen Receptor Coactivator Assay: It is a competition assay, where binding of a test compound to a complex comprised of (i) His6-ERα298-554 protein representing ERα ligand-binding domain, (ii) Tb-labeled His6 antibody, (iii) a fluorescein-labeled PGC1α coactivator peptide (EAEEPSLLKKLLLAPANTQ), and (iv) estradiol, results in a decrease of the TR-FRET signal due to dissociation of the coactivator peptide. His6-ERα298-554 proteins were expressed as WT or D538G or Y537S mutants in E. coli and purified by affinity chromatography. The assay works in a homogeneous mix-and-read format. In a typical experiment, a 4 μL mixture of 0.5 nM His6-ERα298-554, 0.5 nM Tb-labeled His6 antibody, 250 nM PGC1a peptide, and 3 nM estradiol in 100 mM potassium phosphate, pH 7.4, 0.01% Tween-20, 0.02% NaN3, 5 mM DTT, was added to 40 nL test compound in DMSO and incubated overnight at room temperature. The TR-FRET 520:495 nm emission ratio was calculated and used to determine the IC50 value from a dose response curve fit to the 4-parameter logistic equation. The antagonist activity with respect to estrogen receptors in this test is given by the concentration which inhibits 50% of the estrogen receptor activity (or IC50) in nM.

Assay: Cell-Based Assays of c-Kit Mutant Kinase Activity: The c-Kit mutant D816V inhibitors were assessed using an engineered BaF3-FL KIT D816V or BaF3-FL KIT V560G/D816V cell line. The BaF3-FL KIT D816V cell lines were created by introduction of KIT mutant (D816V) full length constructs that render the cells dependent on the introduced kinase for growth. Inhibitors of c-Kit mutant D816V kinase reduce or eliminate the mediated c-kit mutant D816V kinase activation, resulting in reduced cell proliferation of the BaF3-FL Kit mutant D816V cells. This inhibition is measured by the effect of compound concentration on cell growth to assess IC50 values. BaF3-FL KIT D816V cells were seeded at 1×104 cells per well of a 96 well cell culture plate in 50 μl of cell culture medium of RPMI Medium 1× (Invitrogen #11875-093) supplemented with 10% FBS (Invitrogen #10438), 1% Non Essential Amino Acids (Invitrogen #11140), 1% Penicillin Streptomycin (Invitrogen #15140), 1% L-Glutamine (Invitrogen #25030-081). Compounds were dissolved in DMSO at a concentration of 5 mM and were serially diluted 1:3 for a total of eight points and added to the cells to a final maximum concentration of 10 μM in 100 μl cell culture medium (final concentration 0.2% DMSO). Cells were also treated with Dasatinib as a positive control. The cells were incubated at 37° C., 5% CO2 for three days. ATPlite Buffer (Perkin Elmer #6016739) and substrate were equilibrated to room temperature, and enzyme/substrate Recombinant Firefly Luciferase/D-Luciferin was reconstituted. The cell plates were equilibrated to room temperature for 30 minutes, then lysed by addition of 25 uL per well of the ATPlite Reagent. The plate was mixed for 5 minutes on a plate shaker to lyse the cells. The plates were read on a Tecan Safire using Luminescence protocol modified to read 0.1s per well. The luminescence reading assesses the ATP content, which correlates directly with cell number such that the reading as a function of compound concentration is used to determine the IC50 value.

Assay: Intracellular Calcium Measurement to Assess Antagonist Activity at Human P2X3 and Human P2X2/3 Receptors: A fluorescent imaging plate reader (FLEX/FLIPR station; Molecular Devices) was used to monitor intracellular calcium levels using the calcium-chelating dye Fluo-4 (Molecular Probes). The excitation and emission wavelengths used to monitor fluorescence were 470-495 nm and 515-575 nm, respectively. Cells expressing purinergic receptors P2X3 (human) or P2X2/3 (human) were plated at a density of 15,000 cells/well in collagen-coated 384-well plates approximately 20 hours before beginning the assay. On the day of the assay, 20 μl of Loading buffer (Hank's balanced salt solution, 20 mM HEPES, 0.5 mM CaCl2, 0.5 mM MgCl2, 0.1% BSA, 5 mM probenecid, 10 mM D-glucose monohydrate, 2 μM Fluo-4, and 5 units/mL, hexokinase, pH=7.4) was added and cells dye-loaded for 90 min at 37° C. The dye supernatant was removed and replaced with 45 μl probenecid buffer (Hank's balanced salt solution, 20 mM HEPES, 0.5 mM CaCl2, 0.5 mM MgCl2, 0.1% BSA, 5 mM probenecid, 10 mM D-glucose monohydrate, pH=7.4). The test compound was added in a volume of 5 μl and allowed to incubate for 30 min at 37° C. The final assay DMSO concentration is 1%. The agonist, α,β-Me-ATP, was added in a volume of 20 μl at a concentration representing the EC80 value. The fluorescence was measured for an interval of 90 sec at 2 sec intervals and analyzed based on the increase in peak relative fluorescence units (RFU) compared to the basal fluorescence. Peak fluorescence was used to determine the response to agonist obtained at each concentration of test compound by the following equation: % Response=100*(RFU(test compound)−RFU(control)/RFU(DMSO)−RFU(control)).

Assay: Intracellular cAMP Accumulation Assay: HEK293 cells stably expressing human APJ receptor were used to assess the activity of compounds. Cultured cells were detached and resuspended in the cAMP Homogeneous Time-Resolved Fluorescence (HTRF) assay buffer (Cisbio cat; #62AM4PEJ). The assay was performed in 384-well assay plates (Perkin-Elmer; cat #6008289) according to assay protocol provided by the manufacturer. Serial dilutions of a compound together with assay buffer containing 0.2 nM IBMX and 2 μM forskolin were added to each well containing 5,000 cells and incubated for 30 minutes at room temperature. Subsequently, cAMP D2 reagent was added in the lysis buffer followed by the EuK antibody (Cisbio; cat #62AM4PEJ) and incubated for 60 min. The fluorescence emission ratio was measured using fluorometer. The intracellular cAMP concentrations (compound-stimulated inhibition of forskolin-mediated cAMP production) were calculated by extrapolation from a standard curve using known cAMP concentrations. The EC50 values were obtained by fitting the data to a sigmoidal concentration-response curve with variable slope. The maximal achievable inhibition of forskolin-induced cAMP levels (Ymax) for each compound was expressed as relative percentage of inhibition attained using pyroglutamated apelin-13 ((Pyrl)apelin-13) peptide, which was set to 100%.

Assay: Biological Activity: Endothelial lipase (EL) and hepatic lipase (HL) activities were measured using a fluorescent substrate, A10070, (Invitrogen, CA) doped into an artificial vesicle containing DMPG (Avanti Polar Lipids) as the excipient. Vesicles were prepared by combining 571 μL of 29 mM DMPG in a 1:1 mixture of MeOH and CHCl3 with 2000 μL of 1 mM A10070 in a 1:1 mixture of MeOH and CHCl3. The mixture was dried under nitrogen in multiple vials then resuspended in 20 mL total volume of 50 mM HEPES pH 8.0 buffer containing 50 mM NaCl and 0.2 mM EDTA. The sample was allowed to sit at room temperature for 15 min and then was sonicated 3×4 mins on ice with a Branson Sonicator using duty cycle 1. This preparation provides vesicles with a mole fraction of 0.11 for the FRET substrate.The enzymatic assay was measured using 384-well white Optiplates. Each well contained 20 μL of assay buffer (50 mM HEPES pH 8.0, 50 mM NaCl and 1 mM CaCl2) and 0.25 μL of a DMSO solution containing a compound of interest. EL or HL (10 μL) was added and allowed to incubate with the compound for 30 min at 37° C. The source of EL was conditioned media obtained from HT-1080 cells that were transformed using RAGE technology (Athersys) to overexpress endogenous EL, and HL was partially purified from conditioned media obtained from COS cells overexpressing HL. The reaction was started by the addition of 10 μL of a 1:10 dilution of vesicles. The final total reaction volume was 20.25 μL. The reaction rates were measured on a Gemini plate reader with an excitation wavelength of 490 nm and an emission wavelength of 530 nm. Readings were taken over a period of 60 minutes, and the slope between 300 and 900 secs of the readout was used to calculate the rate of the reaction.

Assay: Transactivation Assay: In the presence of an activator (agonist), the melanocortin receptor will activate the cAMP pathway which, via the CRE-Luc vector, will result in the synthesis of luciferase. After the addition of a lysis buffer containing a luminescent substrate for luciferase, it will be possible to measure the luminescence proportional to the degree of activation or of inhibition of the receptor. The products are solubilized at 10 mM in DMSO. They are tested in the form of dose-response at a final DMSO concentration of 0.1%. The range comprising 10 points and one zero begins at 10 μM with 4-fold dilutions. For testing agonists, the products are tested alone. For determining the behaviour of antagonists, the products of interest are tested in the presence of 1 nM NDP-MSH (reference agonist). The cells are seeded at a rate of 5000 cells per well (384 well plate) in serum-free DMEM medium, and incubated overnight at 37° C., 5% CO2.The products and the reference ligand (NDP-MSH) are added the following day, and the plates are again incubated for 6 h at 37° C., 5% CO2. After the addition of lysis buffer containing luciferin, the plates are read on a Top-Count instrument. The results are standardized as % activity using the 100% (cells+NDP-MSH at 10 nM) and 0% (cells alone) controls. An EC50 is calculated for each product using the XLFit software. The results are given in nM.

Assay: Cell-Based Assay of NHE-3 Activity (Pre-Incubation Inhibition): Rat and human NHE-3-mediated Na+-dependent H+ antiport was measured using a modification of the pH sensitive dye method originally reported by Paradiso (Proc. Natl. Acad. Sci. USA. (1984) 81(23): 7436-7440). PS120 fibroblasts stably expressing human NHE3 and NHERF2 were obtained from Mark Donowitz (Baltimore, Md.). Opossum kidney (OK) cells were obtained from the ATCC and propagated per their instructions. The rat NHE-3 gene (GenBank M85300) was introduced into OK cells via electroporation, and cells were seeded into 96 well plates and grown overnight. Medium was aspirated from the wells then incubated for 30 min at 37° C. 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 BCECF-AM. Cells were washed once 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 with 0-30 μM test compound. After incubation, NHE-3-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 NHE-3). Changes in intracellular pH were monitored using a FLIPR Tetra® (Molecular Devices, Sunnyvale, Calif.) by excitation at λex 439 to 505 nm, and measuring BCECF fluorescence at λem 538 nm. The initial rate of the fluorescence ratio change was used as a measure of NHE-mediated Na+/H+ activity, and reported as the change in fluorescence ratio per minute. Initial rates were plotted as the average of 2 or more replicates, and pIC50 values were estimated using GraphPad Prism.

UniProt: P41145
Assay: OPRK1 antagonist assay: The cell line for the OPRK1 antagonist assay stably expresses the following elements. The carboxy terminus of the OPRK1 receptor has a 7 amino acid linker, followed by the TEV protease cleavage site and a GAL4-VP16 fusion protein. The cell line also expresses a b-arrestin-2-TEV protease fusion protein and contains a reporter construct consisting of the UAS response element and the b-lactamase (bla) reporter gene. Upon activation of the receptor, g-protein receptor kinase (GRK) phosphorylates specific intracellular residues of OPKR1 and this induces recruitment of B-arrestin2-TEV protease fusion protein. The TEV protease recognizes and cleaves the TEV site, releasing the GAL4-VP16 fusion protein, which then translocates to the nucleus. The GAL4-V16 binds to the UAS element, driving expressing of the b-lactamase gene. B-lactamase expression is detected with the cell permeable, fluorescent substrate, CCF4-AM. This substrate consists of coumarin tethered to fluoroscein via a b-lactam ring. In the absence of b-lactamase, excitation of the dye with 405 nm light results in FRET from the coumarin to fluoroscein and emission of green (525 nm maximum) light. B-lactamase cleavage of the substrate separates the courmarin fluorophore from the fluorscein, and 405 nm excitation results in blue (460 nm maximum) emission. The assay is monitored by the blue/green emission ratio. The antagonist assay is performed by seeding the cells into 384 well plates and incubating them 16-24 hours at 37° C. Test antagonist compounds are added and incubated for 30 minutes at 37° C. Next an EC80 challenge of U-50488 (OKRK1 agonist) is added and the samples are incubated for 4 hours at 37° C., followed by addition of CCF4-AM substrate. The plates are then incubated 2 hours at room temperature in the dark and the blue/green ratio determined on a fluorescent plate reader. See J Biomol Screen April 2009, vol. 14 no. 4, pp 381-394.
