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.

Assay: Enzyme Inhibition Assay: Measurements were performed using a modification of the scintillation proximity assay platform described previously by Georgopapadakou, N. H. et al. (22nd International Congress on Chemotherapy, 2001, Abstract P16.001). Compounds were solubilised in DMSO at a top concentration of 10 mM and serially diluted in half log steps to achieve a range of final assay concentrations of 100 uM to 1 nM. Compound at each concentration (100-fold final) was added to white 384 well plates in a volume of 0.5 ml. Human, A. fumigatus, T. brucei or L. major N-myristoyl transferase enzyme, dissolved to a working concentration of 10 nM in assay buffer (30 mM Tris/HCl pH 7.4, 0.5 mM EGTA, 0.5 mM EDTA, 1.25 mM DTT, 0.1% Triton X-100), was then added to columns 1 to 11 and 13 to 23 of the plates in a volume of 20 ml. To columns 12 and 24, 20 ml assay buffer was added to provide a no enzyme control. Following a 5 minute incubation at room temperature the substrates (GCGGSKVKPQPPQAK(Biotin)-Amide and myristoyl coenzyme A), dissolved in assay buffer, were added to all wells in a volume of 20 ml to start the reaction. The final concentrations of peptide and 3H-myristoyl coenzyme A were 0.5 mM and 125 nM respectively and the specific activity of the radiolabel was 8 Ci/mmol. Plates were then incubated at room temperature for up to 50 minutes (dependant upon the period of linearity for the different enzyme species) before SPA beads, suspended to 1 mg/ml in a stop solution (200 mM Phosphoric Acid/NaOH pH 4, 750 mM MgCl2), were added in a volume of 40 ml.

Assay: Enzyme Assay: The assay for the determination of Pim activity is based on the formation of phosphorylated biotinylated-BAD peptide at the Serine 112 residue (S112) and employs HTRF® (homogeneous time resolved fluorescence) technology to detect the product in a 96-well plate format. The phosphorylation of biotinylated-BAD (S112) peptide by full length recombinant Pim-1, Pim-2, or Pim-3 protein was detected with streptavidin:Allophycocyanin (APC) conjugate and a europium (Eu) labeled antibody directed against phosphorylated-BAD (S112). Excitation of Eu by a high energy laser light (337 nm) leads to a transfer of energy to the APC molecule, and results in an emission at 665 nm. The fluorescence is directly proportional to the amount of phosphorylated BAD peptide present in the reaction.Compounds were prepared in DMSO by conducting 3-fold serial dilutions to give a 10-point dosing curve having a high dose of 1 uM. A reference compound was included on each assay plate in order to validate that plate; on

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.)
