UniProt: O14649
Assay: In Vitro Electrophysiological Assay: Table 1: In Vitro Electrophysiological Analysis of the Human TASK-1 and TASK-3 Channels Via Two-Electrode Voltage Clamp Technique in Xenopus laevis Oocytes. Xenopus laevis oocytes were selected as described elsewhere by way of illustration [Decher et al., FEBS Lett. 492, 84-89 (2001)]. Subsequently, the oocytes were injected with 0.5-5 ng of a cRNA solution coding for TASK-1 or TASK-3. For the electrophysiological analysis of the channel proteins expressed in the oocytes, the two-electrode voltage clamp technique [Stühmer, Methods Enzymol. 207, 319-339 (1992)] was used. The measurements were conducted as described [Decher et al., FEBS Lett. 492, 84-89 (2001)] at room temperature (21-22° C.) using a Turbo TEC 10CD amplifier (NPI), recorded at 2 kHz and filtered with 0.4 kHz. Substance administration was performed using a gravitation-driven perfusion system. Here, the oocyte is located in a measuring chamber and exposed to the solution stream of 10 ml/min. The level in the measuring chamber is monitored and regulated by sucking off the solution using a peristaltic pump.

Assay: Inhibitory Effect on hCYP11B2: The pcDNA3.1-human CYP11B2 plasmid was transfected into a Chinese hamster lung fibroblast V79 cell line to produce a cell line stably expressing human CYP11B2 gene.The cells were cultured and grown in the Dulbecco's modified Eagle's/Ham's medium supplemented with 10% fetal bovine serum and 1% G418 disulfate solution under the environment of 37° C., 95% air, and 5% CO2, and the grown cells were harvested.Then, the cells were fractionated to obtain mitochondria by reference to a method described in Chabre et al. JCE 86 M 85 (11) 4060-68, 2000. In particular, the cells suspended in a 5 mmol/L Tris-HCl buffer (pH 7.4) containing 250 mmol/L sucrose were homogenized in a Teflon (Registered Trademark) Potter Elvehjem homogenizer, and then the suspension was centrifuged (800×g, 15 min.). The supernatant was separated and again centrifuged (10000×g, 15 min.) to obtain a pellet (mitochondrial fraction).The mitochondrial fraction diluted with a buffer containing 10 mmol/L KH2PO4, 10 mmol/L Tris, 20 mmol/L KCl, 25 mmol/L sucrose, 5 mmol/L MgCl2, and 0.05% bovine serum albumin was dispensed to a 96-well plate. 0.5 μmol/L Deoxycorticosterone, 150 μmol/L NADPH and a compound of each concentration were added to each well, and incubated for 1.5-2 hours at room temperature to produce aldosterone. An amount of the produced aldosterone in the incubated solution was determined by using HTRF (Homogeneous Time Resolved Fluorescence) method.IC 50 (nmol/L) was calculated by analyzing the aldosterone production inhibition rate (%) of each concentration of compounds by non-linear regression to a logistic curve.

Assay: transient transactivation assay: The primary screen was performed by transient transactivation assays. These cell-based assays were carried out using Cos-7 cells transfected with a chimeric human RORγ-Gal4 receptor expression plasmid and a 5Gal4 pGL3 TK Luc reporter plasmid. Transfections were performed by a chemical agent (Jet PEI). Transfected cells were distributed in 384-wells plates and were allowed to recover for 24 h. The culture medium was then removed and fresh medium containing the compounds to be tested was added (final concentration ranging from 10−4 M to 3 10−10 M). After an overnight incubation, luciferase expression was measured by adding SteadyGlo according to the manufacturer's instructions (Promega). T0901317 at 10−5 M was used as reference. Results were expressed as fold induction compared to basal level or as percentage activity compared to references taken as 100% (basal) or 0% (T0901317). Dose-effect curves and IC50 were calculated using the software Assay Explorer (MDL).

Assay: CFTR-YFP Assay: This protocol is designed to selectively screen small molecule compounds for F508del CFTR corrector activities in the YFP (yellow fluorescent protein) flux assay. In this protocol, the cells are incubated with testing compounds for 24 hours, washed with PBS, stimulated with forskolin and a standard potentiator, and fluorescence in each plate well is measured kinetically read on a 384-well plate reader, such as the Hamamatsu FDSS-6000. YFP fluorescence intensity values are acquired at high speed before and after iodide buffer is injected to the assay cells. Iodide enters the cells via active CFTR channels in the plasma membrane, and quenches the YFP fluorescence. The rate of fluorescence quenching is proportionate to the total CFTR activity in the cell membrane. F508del CFTR correctors increase the number of CFTR molecules in the testing cell plasma membrane, and thereby accelerate YFP quenching.

Assay: 3H-cGAMP Filtration Binding Assay (HAQ STING): The compounds were serially titrated by the Hamilton STARPlus CORE in a 96-well plate (Greiner, #651201) using a 1:3 ten-point dose response format. After compound preparation, a 2.2 ug/ml working concentration of STING membrane (SEQ. ID. No. 2) was prepared by diluting concentrated membrane into assay buffer (1×PBS; Invitrogen #SH30028.02) and douncing 7× using a manual tissue homogenizer (Wheaton, #357546). 148 uL of prepared membrane was then manually added to each well of a 96-well deep-well polypropylene plate (Fisher Scientific, #12-566-121). Following membrane addition, 2 uL of either titrated test compound, DMSO control (Sigma #276855), or cold cGAMP control (prepared in-house) was added to the appropriate wells using a Biomek FX. Compound and membrane then preincubated for 60 min at RT to allow compound binding to equilibrate. Following equilibration, 8 nM of [3H] c-GAMP ligand was prepared by diluting into assay buffer, and 50 uL of this working stock was then manually added to each well of the assay plate. Plates were then incubated at RT for 60 min, and the contents of each assay plate were then filtered through a 96-well GF/B filter plate (PerkinElmer, #6005250) using a TomTec MachIII Cell Harvester equipped with 20 mM HEPES buffer (Fisher Scientific, #BP299500). The filter plates were then dried at 55° C. for 30 min using a pressurized VWR oven before 30 uL of Ultima GoldF scintillate was added to each well. Tritium levels for each reaction well were then measured using a PerkinElmer TopCount plate reader.

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))The Examples were tested in triplicates per plate and mean values were plotted in Excel XLFit to determine IC50 values at the human P2X3 and human P2X2/3 receptors, percentage of maximal inhibition and the Hill coefficients.

Assay: Exemplary c-Kit Mutant Biochemical Assay: The c-kit mutant D816V (or kinase domain thereof) is an active kinase in AlphaScreen. IC50 values are determined with respect to inhibition of c-Kit mutant D816V kinase activity, where inhibition of phosphorylation of a peptide substrate is measured as a function of compound concentration. Compounds to be tested were dissolved in DMSO to a concentration of 20 mM. These were diluted 30 μl into 120 μl of DMSO (4 mM) and 1 μl was added to an assay plate. These were then serially diluted 1:3 (50 μl to 100 μl DMSO) for a total of 8 points. Plates were prepared such that each kinase reaction is 20 μl in 1× kinase buffer (25 mM HEPES, pH 7.2, 8 mM MgCl2, 2 mM MnCl2, 50 mM NaCl, 0.01% Brij, 1 mM DTT, 0.01% BSA), 5% DMSO and 10 μM ATP. Substrate was 30 nM biotin-(E4Y)10 (EMD Millipore, Cat#12-440). C-kit mutant D816V kinase was at 0.75 ng per sample. After incubation of the kinase reaction for 30 minutes at room temperature, 5 μl of donor beads (Streptavidin coated beads (Perkin Elmer Life Science) final concentration 7.5 μg/ml) in stop buffer (25 mM Hepes pH 7.5, 100 mM EDTA, 0.01% BSA) was added, the sample was mixed and incubated for 20 minutes at room temperature before adding 5 μl of acceptor beads (PY20 coated beads (Perkin Elmer Life Science) final concentration 7.5 ug/ml) in stop buffer. The samples were incubated for 60 minutes at room temperature and the signal per well was read on EnVision reader. Phosphorylated substrate results in binding of the PY20 antibody and association of the donor and acceptor beads such that signal correlates with kinase activity.

Assay: Homogeneous Time Resolved Fluorescence (HTRF) Assay: To determine the potency of compounds for inhibiting nucleotide exchange, various concentrations were incubated with K-Ras G12C (25 nM in reaction, 12.5 nM final). After 18 hours at room temperature, the SOS1 GTP exchange factor (1.67 nM during exchange, 1.25 nM final) was added to initiate nucleotide exchange to GTP (200 μM during exchange, 150 M final). The level of GTP exchange was assessed by addition of a Ras binding domain derived from C-Raf and the HTRF detection antibodies Tb-anti-FLAG and D2-anti-his (Cis-Bio) at 50 nM, 1 nM and 12.5 nM, respectively. After 2 hours, the ratio of 665 nm to 615 nM emission with 320 nM excitation was measured on an Envision plate reader (Perkin Elmer).The final reaction volume was 20l in a ProxiPlate-384F Plus (Perkin Elmer), in buffer containing 20 mM HEPES, 150 mM NaCl, 1 mM MgCl2, 0.1% BSA, 0.03% Tween-20 and 1 mM DTT. K-Ras G12C (residues 2-188) and SOS1 (residues 564-1049) had N-terminal 6-His and the Raf-RBD construct (residues 51-186 of RAFI) had an N-terminal Flag-tag. All constructs were expressed in E. coli and had a Tev cleavage site between the tag and protein of interest that was not used during purification.

Assay: In Vitro Assay: MALT1 protease activity was assessed in an in vitro assay using a tetrapeptide as substrate and full-length MALT1 protein (Strep-MALT1(1-824)-His) purified from baculovirus-infected insect cells. The tetrapeptide LRSR is coupled to AMC (7-amino-4-methylcoumarin) and provides a quenched, fluorescent substrate for the MALT1 protease (SM Biochemicals). Cleavage of AMC from the Arginine residue results in an increase in coumarin fluorescence measured at 460 nm (excitation 355 nm). The final assay buffer consisted of 10 nM FL MALT1 protein, 200 μM Ac-LRSR-AMC, 50 mM Tris pH 7.5, 0.6 M Citrate, 1 mM DTT, 1 mM EDTA, 0.05% BSA and 1.5% DMSO. Test compounds were spotted at 50 nL in 100% DMSO per well of a black 384-Proxiplate (Perkin Elmer). Test compound concentrations ranged from 30 μM to 0.5 nM using 11 dilution steps (1:3). Background signal was measured from control wells containing assay buffer without enzyme which functions as low control (LC). High control (HC) values were generated using the reaction with enzyme but no compound treatment. Compounds were pre-incubated with MALT1 enzyme for 50 minutes at RT. Substrate was added subsequently and fluorescence was measured in Labsystems fluoroskan at excitation 355 nm and emission 460 nm to determine time 0. The reaction was subsequently incubated for 4 h at RT and fluorescence was measured.
