Assay: DELFIA Assay: R3 domains of human XIAP (covering amino acids 241 to 356; XIAP BIR3) and cIAPl (covering amino acids 256 to 363; cIAPl BIR3) were expressed and purified from Ecoli as GST-fusion proteins. Peptide AVPIAQKSE-Lys(Biotin), representing the N-terminus of mature human SMAC (SMAC peptide), was used as interaction partner in the protein- peptide interaction assay.BIR3 domains (10 nM) were incubated with SMAC peptide (10 nM) in assay buffer (50 mM Tris, 120 mM NaCl, 0.1% BSA, 1 mM DTT, 0.05% TritonXlOO) for one hour at room temperature in the presence of inhibitiory compounds. The assay mixture was transferred to a strepatvidin coated plate and incubated for one hour at room temperature to allow binding of the biotinylated peptide and associated BIR3 domains to the plate. After several washing steps Eu labeled anti-GST antibody (e.g. Perkin Elmer DELFIA Eu-Nl- antiGST AD0250) was added to detect BIR3 domain-SMAC peptide interactions according to Perkin Elmer's instructions. Briefly, the antibody was added (dilution 1:5000 in Perkin Elmer DELFIA Assay Buffer 2013-01) and incubated for one hour. After 3 washing steps using Delfia Washing Buffer (Perkin Elmer DELFIA Wash 2013-05), Enhancement Solution (Perkin Elmer Enhancement Asolution 2013-02) was added and incubation continued for 10 minutes. Time resolved Europium fluoresecence was measured in a Wallac Victor using Standard assay settings.

Target: Serine/threonine-protein kinase pim-2 (SINGLE PROTEIN), Homo sapiens
UniProt: Q9P1W9
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): 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 384-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 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer]. Final concentrations either Pim-1 enzyme [5 pM], or Pim-2 enzyme [0.5 pM], DMSO [1%], BLC BAD (S112) [0.5 μM], ATP [1.5 μM], streptavidin:Allophycocyanin [0.002 mg/mL] and biotinylated-BAD (S112) mAb [100 pM]. Initial incubations were carried out at RT (22° C.) for 30 min for both Pim-1 and for Pim-2. Pim enzyme is added to compound in buffer, and plates are incubated of 30 min. Biotinylated BAD and ATP are added and plates are incubated for 1 h. A mixture of labeled p-BAD (S112) mAb and quench/detection buffer are added and incubated for 2 h. Fluorescence was measured by an HTRF® Envision microplate reader.

UniProt: O60674
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: Trans-Phosphorylation Assay: The inhibitory activity of putative kinase inhibitors and the potency of selected compounds were determined using a trans-phosphorylation assay.Specific peptide or protein substrates were trans-phosphorylated by their specific ser-thr or tyr kinase in the presence of ATP traced with 33P-gamma-ATP, and in the presence of their own optimal buffer and cofactors. At the end of the phosphorylation reaction, more than 98% unlabeled ATP and radioactive ATP were captured by an excess of the ion exchange dowex resin; the resin then settled down to the bottom of the reaction plate by gravity. Supernatant was subsequently withdrawn and transferred into a counting plate, then evaluated by beta-counting. Kinase Buffer (KB):The buffer for PIM2 assay was composed of HEPES 50 mM, at pH 7.5, with 1 mM MgCl2, 1 mM DTT, 3 uM Na3VO4, and 0.2 mg/mL BSA.Â  Full-length human PIM2 was expressed and purified as described in Fedorov O, et al., PNAS 2007 104, 51, 20523-28.

UniProt: Q92633
Assay: Receptor Assay: Engagement of the LPA1 receptor by its ligand, oleoyl-L-Î±-lysophosphatidic acid (LPA), leads to the release of intracellular stores of calcium into the cytoplasm mediated through a Gq-driven increase in inositol triphosphate (IP3) levels. Gq is a heterotrimeric G protein subunit that activates phospholipase C. The ability of test compounds to prevent LPA-driven intracellular release of stored calcium from RH7777 cells expressing human LPA1 receptors was assayed by stimulating the cells with LPA in the presence of various test compounds to measure the test compounds' antagonism, i.e. activity in vitro.Â  Approximately 10,000 cells in normal culture medium (Dulbecco's Modified Eagle Media, 10% Foetal Calf Serum) were dispensed per assay well in a black clear bottom collagen coated 384 well plate (Beckton Dickinson). Cells were allowed to settle for thirty minutes at room temperature before being incubated overnight at 37° C., 5% CO2. Sixteen to twenty hours after dispensing, the cells were loaded with a calcium-sensitive fluorescent dye by replacing the culture medium with assay buffer (1x Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH7.4) containing 1.25 mM probenecid and 1x Calcium 5 Reagent (Molecular Devices). Cells were incubated at 37° C. for one hour to allow for dye uptake.

Assay: Luciferase Assay: The Huh-7 cells transfected with HCV replicons system were seeded into 96-well plates (8,000 cells in 125 μL/well) respectively; each test compound was diluted to desired concentration using 5-fold serial dilutions protocol, 10 doses in duplicate, and added to wells with POD™ 810 Plate Assembler. The plates were incubated in a CO2 incubator for 72 hours; after that, 40 μL of Luciferase assay substrate (Promega Bright-Glo) was added to each well, and detected by a chemiluminescence detection system (Topcount Microplate Scintillation and Luminescence Counter) 5 minutes later; the EC50 (half-maximal effective concentration, concentration for 50% of maximal effect) values of test compounds were analyzed by GraphPad Prism software, respectively. In this paper, experiments were repeated twice and set the holes without compounds as negative control.

UniProt: Q64373
Assay: Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay: The inhibition constant (Ki) is the dissociation constant of an enzyme-inhibitor complex or a protein/small molecule complex, wherein the small molecule is inhibiting binding of one protein to another protein or peptide. Where the Ki for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-XL) is greater than the limits of detection of the assay used. Where the binding selectivity ratio for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the selectivity of a particular compound for Bcl-2 over Bcl-XL is at least as great as the number indicated. Where the Ki for a compound is represented as < (less than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-2) is lower than the limit of detection of the assay used. Inhibition constants were determined using Wang's equation (Wang Z-X).
