UniProt: P19099
Assay: Inhibition Assay: G-402 cells can be obtained from ATCC (CRL-1440) and were originally derived from a renal leiomyoblastoma.The expression plasmids contains the ORF for either human/cyno CYP11B1 or CYP11B2 under the control of a suitable promoter (CMV-promoter) and a suitable resistance marker (neomycin). Using standard techniques the expression plasmid is transfected into G-402 cells and these cells are then selected for expressing the given resistance markers. Individual cell-clones are then selected and assessed for displaying the desired enzymatic activity using 11-Deoxycorticosterone (Cyp11B2) or 11-Deoxycortisol (Cyp11B1) as a substrate.G-402 cells expressing CYP11 constructs were established as described above and maintained in McCoy's 5a Medium Modified, ATCC Catalog No. 30-2007 containing 10% FCS and 400 μg/ml G418 (Geneticin) at 37° C. under an atmosphere of 5% CO2/95% air. Cellular enzyme assays were performed in DMEM/F12 medium containing 2.5% charcoal treated FCS and appropriate concentration of substrate (0.3-10 uM 11-Deoxycorticosterone, 11-Deoxycortisol or Corticosterone). For assaying enzymatic activity, cells were plated onto 96 well plates and incubated for 16 h. An aliquot of the supernatant is then transferred and analyzed for the concentration of the expected product (Aldosterone for CYP11B2; Cortisol for CYP11B1). The concentrations of these steroids can be determined using HTRF assays from CisBio analyzing either Aldosterone or Cortisol.

Assay: HBV DNA Quantification Assay: A HepG2 cell line overexpressing the HBV virus attachment receptor sodium-taurocholate cotransporting polypeptide (NTCP) was grown to confluency in DMEM growth medium, Dulbecco's Modified Eagle Medium without sodium pyruvate (Life Technologies, Rockville, Md.) supplemented with 10% FBS (Thermo Scientific, Waltham, Md.), 1% penicillin/streptomycin (Life Technologies, Rockville, Md.) and 2 mM L-glutamine (Life Technologies, Rockville, Md.) in T175 flasks. Cells were infected with HBV AD38 viral particles (Texcell, Frederick, USA) at 4000 genome equivalents per cell. After allowing viral infection to take place for 4 days, the infected cells were harvested from the flasks by trypsinization, washed twice with OptiMEM (Life Technologies, Rockville, Md.) and re-suspended in DMEM containing 2% FBS and 1% DMSO at a density of 0.25E6 cells/ml. Infected cells were seeded on 384 well collagen coated plates (Greiner, Austria) at a density of 20,000 cells/well containing serially diluted compounds of the present disclosure or DMSO (0.5%) in a final volume of 80 μl. The assay plates were incubated for a period of 5 days and the antiviral activity of the test compounds were assayed by detecting the presence of HBV DNA in the culture supernatant using the QuantiGene 2.0 nucleic acid quantification kit (Affymetrix, Santa Clara, Calif.).The culture supernatant was harvested and treated with lysis buffer containing Proteinase K (Affymetrix, Santa Clara, Calif.). The supernatant was incubated with HBV viral DNA specific probes (Affymetrix, Santa Clara, Calif.) for 30 minutes at 55° C. This was followed by addition of 0.2M NaOH for 30 minutes at room temperature to denature the DNA, followed by addition of Neutralization buffer (Affymetrix, Santa Clara, Calif.). The resulting lysed and neutralized supernatant was then added to QuantiGene 2.0 384 well plates coated with capture oligonucleotides and incubated overnight at 55° C. The HBV specific probe set consists of Capture Extender oligonucleotides (CE's) and blocking probes. Following the overnight incubation, the wells were incubated for one hour sequentially with a Pre-Amplifier, Amplifier and Labeled probes conjugated to alkaline phosphatase with a wash step between incubations. After the final wash step, the alkaline phosphatase substrate (Luminol APS5) was added and the resulting luminescence signal was read in an EnVision Multilabel Plate Reader (PerkinElmer, Santa Clara, Calif.). The EC50 values were calculated from the fit of the doseresponse curves to a four-parameter equation. All EC50 values represent geometric mean values of a minimum of four determinations.

Target: Proto-oncogene Wnt-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P04628
Assay: The screening assay for Wnt activity: The screening assay for Wnt activity is described as follows. Reporter cell lines can be generated by stably transducing cancer cell lines (e.g., colon cancer) or primary cells (e.g., IEC-6 intestinal cells) with a lentiviral construct that includes a Wnt-responsive promoter driving expression of the firefly luciferase gene.SW480 colon carcinoma cells were transduced with a lentiviral vector expressing luciferase with a human Sp5 promoter consisting of a sequence of eight TCF/LEF binding sites. SW480 cells stably expressing the Sp5-Luc reporter gene and a hygromycin resistance gene were selected by treatment with 150 μg/ml of hygromycin for 7 days. These stably transduced SW480 cells were expanded in cell culture and used for all further screening activities. For Sp5-Luc reporter gene assays, the cells were plated at 10,000 cells/well in 96-well plates with growth medium containing 10% fetal calf serum and incubated overnight at 37° C. and 5% CO2. Each compound was dissolved in DMSO as a 10 mM stock in standard j-vials and used to prepare compound source plates in dose-response format with 3-fold serial dilutions and a 10 mM top concentration. Compound transfer from serially diluted source plates to assay plates containing the cells was accomplished using a pintool (Multimek 96, Beckman equipped with V&P Scientific FP1S50H pins) based liquid handling protocol. This protocol used a slotted pin to transfer 50 nl of compound from a source plate well to an assay plate well containing 50 μl of cells in growth medium. The 1000-fold dilution resulted in a final DMSO concentration of 0.1% on the cells in each well. Control wells received 50 nl of DMSO treatment for normalization and calculating IC50 values. The treated cells were incubated at 37° C. and 5% CO2 for an additional forty-two hours. Following incubation, the growth medium was removed and 50 μl of BrightGlo luminescence reagent (Promega) was added to each well of the 96-well assay plates. The plates were placed on an orbital shaker for 5 min and then luminescence was quantified on the Victor3 (Perkin Elmer) plate reader. Readings were normalized to DMSO only treated cells, and normalized activities were utilized for IC50 calculations using the dose-response log (inhibitor) vs. response-variable slope (four parameters) nonlinear regression feature available in GraphPad Prism 5.0 or 6.0.

Assay: Class B Enzyme Assay: The Class B enzyme activities were measured in the presence of the test inhibitor in a fluorescence assay against a commercially available substrate consisting of a cephalosporin core linking 7-hydroxycoumarin to fluorescein (CCF2-FA). The enzyme (NDM-1, IMP-1 or VIM-1) and the substrate were diluted in 100 mM KH2PO4 buffer (pH 7) containing 0.005% Tween-20 and 10 μM ZnSO4. In the assay, the final concentration of enzyme was 1 pM, 2 pM and 30 pM for NDM-1, IMP-1 and VIM-1, respectively, and the final concentration of CCF2-FA was 1.25 μM. The test inhibitor was dissolved in dimethylsulfoxide and diluted 1:50 in the assay, resulting in a final concentration range of 20 uM to 0.00063 uM. In a 384-well microplate, the test inhibitor was incubated with the metallo-β-lactamase enzyme and the substrate for 2 hours at 25° C. Fluorescence at 460 nm following excitation at 405 nm was measured. The IC50 value was determined from semi-logarithmic plots of enzyme inhibition versus inhibitor concentration, with a curve generated using a 4-parameter fit.

Target: cGMP-dependent 3',5'-cyclic phosphodiesterase (SINGLE PROTEIN), Homo sapiens
UniProt: O00408
Assay: Enzymatic Assay: An IMAP TR-FRET-based phosphodiesterase assay was developed using the PDE2A isoform. IMAP technology is based on high-affinity binding of phosphate by immobilized metal (MIII) coordination complexes on nanoparticles. The IMAP binding reagent recognizes phosphate groups on AMP or GMP generated from cAMP or cGMP in a PDE reaction. Cyclic nucleotides that carry a phosphodiester bond and not a free phosphate are not recognized by the binding reagent. The time resolved fluorescence resonance energy transfer (TR-FRET) is afforded by a Terbium (Tb)-Donor pre-bound to the nanoparticles. FRET occurs when the fluorescent-labeled AMP or GMP product of a PDE reaction binds and comes into close proximity to the Tb-Donor complex. Due to the long lifetime of Tb fluorescence, detection can be run in time-resolved mode to reduce or eliminate interference from auto-fluorescent compounds.The IMAP TR-FRET PDE2A assay was performed in 1536-well white plates. A total of 250 pg per well of FLAG-tagged PDE2A1 (amino acids 2-941) was dispensed in 2.5 μL IMAP assay buffer consisting of 10 mM Tris pH 7.2, 10 mM MgCl2, 1 mM DTT, and 0.1% fatty acid free BSA. 30 nL of compound was then added from 1 mM stocks in DMSO using a Kalypsys Pintool. Plates were incubated for 5 min at room temperature before dispensing 1.5 μL of 533 nM FAM-cAMP substrate for a final concentration of 200 nM. Following a brief centrifugation, plates were incubated for 30 min at room temperature. The assay was terminated by adding 5 μL IMAP binding reagent Tb complex to each well which was prepared according to manufacturer's recommendations (Molecular Devices). Plates were incubated an additional 90 minutes at room temperature and read on a Viewlux plate reader. All compounds were solvated at a concentration of 10 mM in DMSO and tested in 11-point half-log dose-response. Curve fitting and IC50 values were determined using a standard four parameter fit.PDE2

Target: Glutaminase kidney isoform, mitochondrial (SINGLE PROTEIN), Homo sapiens
UniProt: O94925
Assay: Enzymatic Activity Assay: The inhibition of purified recombinant human GAC by varying concentrations of inhibitors is assessed via a dual-coupled enzymatic assay. The glutamate produced by the glutaminase reaction is used by glutamate oxidase to produce α-ketoglutarate, ammonia, and hydrogen peroxide, with this hydrogen peroxide subsequently being used by horseradish peroxidase to produce resorufin in the presence of Amplex UltraRed. The assay buffer consisted of 50 mM Hepes (pH 7.4), 0.25 mM EDTA and 0.1 mM Triton X-100. GAC was incubated with potassium phosphate (10 minutes at room temperature) prior to incubation with inhibitor (10 minutes at room temperature). The final reaction conditions were as follows: 2 nM GAC, 50 mM potassium phosphate, 100 mU/mL glutamate oxidase (Sigma), 1 mM glutamine (Sigma), 100 mU/mL horseradish peroxidase (Sigma), 75 μM Amplex UltraRed (Life Technologies), and 1% (v/v) DMSO. The production of resorufin was monitored on a Perkin Elmer Envision plate reader (excitation 530 nm, emission 590 nm) either in a kinetics or endpoint mode (at 20 minutes). IC50 values were calculated using a four-parameter logistic curve fit.

Assay: Biochemical JAK Kinase Assays: A panel of four LanthaScreen JAK biochemical assays (JAK1, 2, 3 and Tyk2) were carried in a common kinase reaction buffer (50 mM HEPES, pH 7.5, 0.01% Brij-35, 10 mM MgCl2, and 1 mM EGTA). Recombinant GST-tagged JAK enzymes and a GFP-tagged STAT1 peptide substrate were obtained from Life Technologies.Serially diluted compounds were pre-incubated with each of the four JAK enzymes and the substrate in white 384-well microplates (Corning) at ambient temperature for 1 h. ATP was subsequently added to initiate the kinase reactions in 10 μL total volume, with 1% DMSO. The final enzyme concentrations for JAK1, 2, 3 and Tyk2 are 4.2 nM, 0.1 nM, 1 nM, and 0.25 nM respectively; the corresponding Km ATP concentrations used are 25 μM, 3 μM, 1.6 μM, and 10 μM; while the substrate concentration is 200 nM for all four assays. Kinase reactions were allowed to proceed for 1 hour at ambient temperature before a 10 μL preparation of EDTA (10 mM final concentration) and Tb-anti-pSTAT1 (pTyr701) antibody (Life Technologies, 2 nM final concentration) in TR-FRET dilution buffer (Life Technologies) was added. The plates were allowed to incubate at ambient temperature for 1 h before being read on the EnVision reader (Perkin Elmer). Emission ratio signals (520 nm/495 nm) were recorded and utilized to calculate the percent inhibition values based on DMSO and background controls.For dose-response analysis, percent inhibition data were plotted vs. compound concentrations, and IC50 values were determined from a 4-parameter robust fit model with the Prism software (GraphPad Software). Results were expressed as pIC50 (negative logarithm of IC50) and subsequently converted to pKi (negative logarithm of dissociation constant, Ki) using the Cheng-Prusoff equation.

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.

Target: Tyrosine-protein kinase BTK (SINGLE PROTEIN), Homo sapiens
UniProt: Q06187
Assay: In Vitro Kinase Assay: The purpose of the BTK in vitro assay is to determine compound potency against BTK through the measurement of IC50. Compound inhibition is measured after monitoring the amount of phosphorylation of a fluorescein-labeled polyGAT peptide (Invitrogen PV3611) in the presence of active BTK enzyme (Upstate 14-552), ATP, and inhibitor. The BTK kinase reaction was done in a black 96 well plate (costar 3694). For a typical assay, a 24 pL aliquot of a ATP/peptide master mix (final concentration; ATP 10 kM, polyGAT 100 nM) in kinase buffer (10 mM Tris-HCl pH 7.5, 10 mM MgCl2, 200 μM Na3PO4, 5 mM DTT, 0.01% Triton X-100, and 0.2 mg/ml casein) is added to each well. Next, I pL of a 4-fold, 40× compound titration in 100% DMSO solvent is added, followed by adding 15 μL of BTK enzyme mix in 1× kinase buffer (with a final concentration of 0.25 nM). The assay is incubated for 30 minutes before being stopped with 28 μL of a 50 mM EDTA solution. Aliquots (5 μL) of the kinase reaction are transferred to a low volume white 384 well plate (Corning 3674), and 5 μL of a 2× detection buffer (Invitrogen PV3574, with 4 nM Tb-PY20 antibody, Invitrogen PV3552) is added. The plate is covered and incubated for 45 minutes at room temperature. Time resolved fluorescence (TRF) on Molecular Devices M5 (332 nm excitation; 488 nm emission; 518 nm fluorescein emission) is measured. IC50 values are calculated using a four parameter fit with 100% enzyme activity determined from the DMSO control and 0% activity from the EDTA control.
