UniProt: O60674
Assay: HTRF Biochemical Assay: The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 uL of 1.11x enzyme and 1.11x substrate in 1x assay buffer (Invitrogen kinase buffer # PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at room temperature to allow compound binding to equilibrate. After equilibration, 2 uL of 10xATP in 1x assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at room temperature for 120 minutes. At the end of the incubation, 20 uL of 2x stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction.

Assay: PDGFRbeta: Automated FLIPR (Fluorometric Imaging Plate Reader) technology was used to screen for inhibitors of VEGF induced increases in intracellular calcium levels in fluorescent dye loaded endothelial cells. HUVEC (human umbilical vein endothelial cells) (Clonetics) were seeded in 384-well fibronectin coated black-walled plates overnight at 37° C./5% CO2. Cells were loaded with calcium indicator Fluo-4 for 45 minutes at 37° C. Cells were washed 2 times (Elx405, Biotek Instruments) to remove extracellular dye. For screening, cells were pre-incubated with test agents for 30 minutes, at a single concentration (10 uM) or at concentrations ranging from 0.0001 to 10.0 uM followed by VEGF165 stimulation (10 ng/mL). Changes in fluorescence at 516 nm were measured simultaneously in all 384 wells using a cooled CCD camera. Data were generated by determining max-min fluorescence levels for unstimulated, stimulated, and drug treated samples.

Assay: In Vitro JAK Kinase Assay: Compounds herein were tested for inhibitory activity of JAK targets according to the following in vitro assay described in Park et al., Analytical Biochemistry 1999, 269, 94-104. The catalytic domains of human JAK1 (a.a. 837-1142), Jak2 (a.a. 828-1132) and Jak3 (a.a. 781-1124) with an N-terminal His tag were expressed using baculovirus in insect cells and purified. The catalytic activity of JAK1, JAK2 or JAK3 was assayed by measuring the phosphorylation of a biotinylated peptide. The phosphorylated peptide was detected by homogenous time resolved fluorescence (HTRF). IC50s of compounds were measured for each kinase in the 40 microL reactions that contain the enzyme, ATP and 500 nM peptide in 50 mM Tris (pH 7.8) buffer with 100 mM NaCl, 5 mM DTT, and 0.1 mg/mL (0.01%) BSA. For the 1 mM IC50 measurements, ATP concentration in the reactions was 1 mM. Reactions were carried out at room temperature for 1 hr and then stopped with 20 μL 45 mM EDTA, 300 nM SA-APC, 6 nM Eu-Py20 in assay buffer (Perkin Elmer, Boston, Mass.). Binding to the Europium labeled antibody took place for 40 minutes and HTRF signal was measured on a Fusion plate reader (Perkin Elmer, Boston, Mass.).

Assay: Fluorescence-Polarization Binding Assay: The binding affinity of the MDM2 inhibitors was determined using an optimized, sensitive and quantitative fluorescence polarization-based (FP-based) binding assay using a recombinant human His-tagged MDM2 protein (residues 1-118) and a fluorescently tagged p53-based peptide.The design of the fluorescence probe was based upon a previously reported high-affinity p53-based peptidomimetic compound (5-FAM-beta Ala-beta Ala-Phe-Met-Aib-pTyr-(6-Cl-LTrp)-Glu-Ac3c-Leu-Asn-NH2 (SEQ ID NO: 1)) Garcia-Echeverria et al., J. Med. Chem. 43: 3205-3208 (2000)). This tagged peptide is called PMDM6-F. The Kd value of PMDM6-F with the recombinant MDM2 protein was determined from the saturation curve. MDM2 protein was serially double diluted in a Dynex 96-well, black, round-bottom plate, and the PMDM6-F peptide was added at 1 nM concentration. The assay was performed in the buffer: 100 mM potassium phosphate, pH 7.5; 100 ug/mL bovine gamma globulin; 0.02% sodium azide, 0.01% Triton X-100).

Target: N-formyl peptide receptor 2 (SINGLE PROTEIN), Homo sapiens
UniProt: P25090
Assay: Electrophysiology Assay: Cells: The hNav1.7 expressing HEK-293 cells were plated on 35 mm culture dishes pre-coated with poly-D-lysine in standard DMEM culture media (Mediatech, Inc., Herndon, Va.) and incubated in a 5% CO2 incubator at 37° C. CuItured cells were used approximately 12-48 h after plating.Electrophysiology: On the day of experimentation, the 35 mm dish was placed on the stage of an inverted microscope equipped with a perfusion system that continuously perfuses the culture dish with fresh recording media. A gravity driven superfusion system was used to apply test solutions directly to the cell under evaluation. This system consists of an array of glass pipette glass connected to a motorized horizontal translator. The outlet of the shooter was positioned approximately 100 μm from the cell of interest.Whole cell currents were recorded using the whole-cell patch clamp configuration using an Axopatch 200B amplifier (Axon Instruments, Foster City Calif.), 1322A A/D converter (Axon Instruments) and pClamp software (v. 8; Axon Instruments) and stored on a personal computer. Gigaseals were formed and the whole-cell configuration was established in voltage clamp mode, and membrane currents generated by hNav1.7 were recorded in gap-free mode. Borosilicate glass pipettes have resistance values between 1.5 and 2.0 MΩ when filled with pipette solution and series resistance (<5 MΩ) was compensated 75-80%. Signals were sampled at 50 kHz and low pass filtered at 3 kHz.Voltage Protocols: After establishing the whole-cell configuration in voltage clamp mode, two voltage protocols were run to establish: 1) the holding potential; and 2) the test potential for each cell.

Assay: Biochemical JAK and Tyk2 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 or discretely 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: Cellular Enzyme Assay: 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 μM 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.

Target: Sodium channel protein type 5 subunit alpha (SINGLE PROTEIN), Homo sapiens
UniProt: Q14524
Assay: In Vitro Assay: HEK 293 cells stably transfected with either Nav 1.7 or with Nav 1.5 were recorded in population patch-clamp mode with the IonWorks® Quattro automated electrophysiology system in accordance with the manufacturer's specifications (Molecular Devices, LLC, Sunnyvale, Calif.). Sodium channel currents were measured in response to a train of depolarizations that induced successively greater inactivation. Cells were held at −110 mV for three seconds (Nav 1.7) or half a second (Nav 1.5) from a holding voltage of −15 mV, then put through a series of 26 pulses of 150 msec duration to −20 mV at a frequency of 5 Hz. Cells were then left unclamped for a period of 3 to 8 minutes while a single concentration of test compound was added. Cells were then reclamped and put through the same voltage protocol. Current at the end of the 26th pulse to −20 mV was subtracted from the peak current evoked by the 26th pulse to −20 mV to correct for leak current.

Target: Non-receptor tyrosine-protein kinase TYK2 (SINGLE PROTEIN), Homo sapiens
UniProt: P29597
Assay: Enzyme Assay: JAK1, JAK2, JAK3 and Tyk2 were purchased from Carna Biosciences, Inc. As the substrate, LANCE Ultra ULight-JAK1 Peptide (manufactured by PerkinElmer Co., Ltd. (PE)) was used. Dilute solutions of compounds and enzymes in assay buffer (50 mM HEPES pH7.5, 1 mM EGTA, 1 mM MgCl2, 2 mM DTT, 0.01% Tween20) were dispensed into wells of a 384-well black plate. After 5 minutes of preincubation, dilute solutions of the substrate and ATP (adenosine triphosphate) were added at a final concentration of 100 μM, and the plate was incubated at room temperature for 2 hours. After addition of a termination reagent containing EDTA (ethylenediamine tetraacetic acid) at a final concentration of 10 mM, LANCE Eu-W1024 Anti-phosphotyrosine (PT66) (manufactured by PE) was added, and after 1 hour of incubation, the fluorescences were measured with ARVO-HTS.
