Target: Serine/threonine-protein kinase B-raf (SINGLE PROTEIN), Homo sapiens
UniProt: P15056
Assay: Raf Activity Assay: Raf and biotinylated Mek, kinase dead, were combined at 2x final concentrations in assay buffer (50 mM Tris, pH 7.5, 15 mM MgCl2, 0.01% BSA and 1 mM DTT) and dispensed 5 ml per well in assay plates (Greiner white 384 well assay plates #781207) containing 0.25 ml of 40x of a Raf kinase inhibitor test compound diluted in 100% DMSO. The plate was incubated for 60 minutes at room temperature. The Raf kinase activity reaction was started by the addition of 5 mL per well of 2xATP diluted in assay buffer. After 3 hours (b-Raf(V600E)) or 1 hour (c-Raf). The reactions were stopped and the phosphorylated product was measured using a rabbit anti-p-MEK (Cell Signaling, #9121) antibody and the Alpha Screen IgG (ProteinA) detection Kit (PerkinElmer #6760617R), by the addition of 10 mL to the well of a mixture of the antibody (1:2000 dilution) and detection beads (1:2000 dilution of both beads) in Stop/bead buffer (25 mM EDTA, 50 mM Tris, pH 7.5, 0.01% Tween20). The additions were carried out under dark conditions to protect the detection beads from light. A lid was placed on top of the plate and incubated for 1 hour at room temperature, then the luminescence was read on a PerkinElmer Envision instrument. The concentration of each compound for 50% inhibition (IC50) was calculated by non-linear regression using XL Fit data analysis software.

Plates were incubated over night at 4° C. The next day the plates were washed with PBS buffer containing 0.05% Tween 20 and further incubated with a mouse monoclonal anti-phospho AKT T308 for 2 h. Plates were washed again as above before addition of a horse anti-mouse-HRP conjugated secondary antibody. Following a 2 h incubation at r.t., plates were washed and QuantaBlu substrate working solution (Thermo Scientific #15169, prepared according to provider's instructions) was added to each well.

Assay: HDAC enzyme inhibitionAssay: HDAC enzyme inhibition assays were performed using purified HDACs 1-10 essentially as described in Beckers et al., 2007, Int. J. Cancer., 121:1138-48 and Perez-Balado et al., 2007, J. Med. Chem., 50:2497-2505. Inhibition assays using nuclear extract were performed essentially as described in Herman et al., 2006, Nat. Chem.

Assay: VEGFR2: Adult human umbilical vein endothelial cells (HUVEC) (Cat# CC-2519, Lonza) were seeded into clear-bottom, TC treated 12 well plates (Cat #665180, Greiner Bio-One) in EGM-2 (Cat# CC-3162, Lonza) at 180,000 cells/well (volume 1 mL), and the plates incubated at 37° C. and 5% CO2 for 6 hours. The media was replaced with EBM-2 (Cat # CC-3156, Lonza)+0.1% BSA (Cat# A8412, Sigma) and cells incubated for a further period (overnight at 37° C. and 5% CO2).96 well Maxisorp immuno plates (Cat #439454, Nunc) were coated with 100 Î¼L of Total VEGFR2 capture antibody (Part #841434, Human Total VEGFR2/FLT4 ELISA Kit, Cat # DYC1780, R&D Systems), or Phospho VEGFR2 Capture antibody (Part #841419, Human Phospho VEGFR2/FLT4 ELISA Kit, Cat# DYC1766, R&D Systems). The plates were covered and incubated at room temperature overnight. The coating antibody was flicked out and the plates washed three times with Wash Buffer (Phosphate buffered saline (137 mM NaCl, 2.7 nM KCl, 8.1 nM Na2HPO4, 1.5 mL KH2PO4, pH 7.2-7.4), 0.05% Tween 20). 300 uL of blocking buffer (5% v/v Tween 20, 5% w/v sucrose in PBS) was then added to wells and plate incubated for 2 hours at room temperature.

Target: Sodium channel protein type 9 subunit alpha (SINGLE PROTEIN), Homo sapiens
UniProt: Q15858
Assay: Nav1.7 In Vitro PX Assay: HEK 293 cells stably transfected with human Nav1.7 were recorded in whole cell voltage clamp mode with the PatchXpress automated electrophysiology system (Molecular Devices, LLC, Sunnyvale, Calif.). Compound effects were measured on a partially inactivated state of the sodium channel. Cells were clamped to a holding potential yielding 20 to 50% inactivation. To elicit sodium current, channels were activated by pulsing to -10 mV for 20 msec. This voltage protocol was repeated at a rate of 0.1 Hz throughout the experiment. A single concentration of test compound was applied to cells for a duration of 3 minutes.

Target: Tyrosine-protein kinase JAK1 (SINGLE PROTEIN), Homo sapiens
UniProt: P23458
Assay: In vitro JAK Kinase Assay: 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.)
