Assay: FRET-Based Membrane Potential Assay: Two days prior to the experiment, frozen HEK293 cells stably expressing recombinant human Nav1.7 were quickly thawed and plated at 25,000 cells/well in growth medium [DMEM (Invitrogen #11965) with 10% HI FBS (Invitrogen #10082), 2 mM glutamine, 100 units/mL penicillin, 0.1 mg/mL streptomycin (PSG, Sigma #G1146), and 500 ug/mL Geneticin (Invitrogen #10131)] in black-walled, clear-bottom 384-well poly-D-lysine-coated assay plates (Greiner Bio-One, Frickenhausen, Germany) and incubated in a humidified 5% CO2 incubator at 37° C. On the day of the assay, medium was removed by aspiration, and cells were washed with assay buffer [HBSS (Invitrogen, Carlsbad, Calif.) containing 20 mM HEPES (Invitrogen, Carlsbad, Calif.)]. After washing, 30 uL assay buffer containing the fluorescent voltage-sensor probe CC2-DMPE (Invitrogen, Carlsbad, Calif.) at 20 uM and 0.01% pluronic F-127 (Invitrogen, Carlsbad, Calif.) was added to the cells. Cells were incubated for 40 minutes at room temperature in the dark. Following the incubation, the cells were washed and 30 uL assay buffer containing 2.5 uM DiSBAC2(3) substrate (Invitrogen, Carlsbad, Calif.) and 0.5 mM VABSC-1 (Invitrogen, Carlsbad, Calif.) was added to the cells. The cells were incubated for 90 minutes at room temperature in the dark. Fluorescence readings were made using a FLIPR TETRA (Molecular Devices, Sunnyvale Calif.) equipped with voltage-sensor probe optics. At the start of each experiment the optimal (EC80) concentration of depolarizing agent (veratridine) was determined by testing a dilution curve of assay buffer containing veratridine (Sigma-Aldrich, St. Louis, Mo.) and 1 mg/mL scorpion venom (SVqq, from Leiurus quinquestriatus; Sigma-Aldrich, St. Louis, Mo.). Compounds were dissolved in dimethyl sulfoxide, and 8-point, 1:3 dilution concentration-response curves were prepared in duplicate in dimethyl sulfoxide, followed by preparation of 0.8 uL/well daughter plates of the dilutions. Test compounds in the daughter plate were diluted to (Ë¿3x) solutions in assay buffer immediately before assaying. Using the FLIPR TETRA, 20 uL of the (3x) compound solutions were first added to the cells, then 20 uL of depolarizing solution (3xEC80 veratridine+SVqq) were added 3 minutes later to activate the channel. Changes in fluorescence were measured at wavelengths of 440-480 nm and 565-625 nm over the course of the experimental run. Membrane depolarization was expressed as a ratio of the maximum F440-480 nm/F565-625 nm reading above average baseline F440-480 nm/F565-625 nm reading. IC50 values were calculated from curve fits of the ratio data using a four-parameter logistic Hill equation (Accelrys Assay Explorer 3.3 Client, Accelrys, San Diego, Calif.) with percent inhibition plotted against compound concentration.

Assay: Biotin Assay: A streptavidin-coated plate (Thermo Scientific, NUNC #436014) was washed three times with 300 μL of PBS-0.05% Tween solution. A biotinylated twenty-six amino acid peptide, corresponding to the BH3 domain of Bim, with the sequence biotin-(β)A-D-M-R-P-E-I-W-I-A-Q-E-L-R-R-I-G-D-E-F-N-A-Y-Y-A-R-R-amide (SEQ ID No. 14), hereafter referred to as biotin-Bim, was obtained (Tufts). The biotin-Bim peptide was diluted to 0.018 μg/mL (5 nM) in SuperBlock blocking buffer in PBS (Thermo Scientific, #37515), and 100 μL of this solution was incubated in the streptavidin-coated plate for 2.5 hours while shaking. Separately, a compound of Formula I or Formula II, which had been prepared in a 10 mM stock DMSO solution, was then incubated with 20 nM GST-Mcl-1 fusion protein in PBS. Compounds were tested in six three-fold dilutions ranging from 20 μM to 0.6 μM, 10 μM to 0.3 or 5 μM to 0.15 μM. In addition, Bim peptide (New England Peptide) was utilized as a control and tested in six-fold dilutions ranging from 100 nM to 3.3 nM. The streptavidin-coated plate which had previously been treated with biotin-Bim peptide was then washed three times with 300 μL of PBS-0.05% Tween solution. A solution of GST-MCL-1 and a compound of Formula I or Formula II (100 μL) was then added to the streptavidin-coated plate, with two wells utilized as controls (PBS buffer only, no GST-MCL-1 or biotin-Bim) and two wells as an alternative control (containing GST-MCL-1 but no biotin-Bim), and four three-fold dilutions of DMSO (0.2%, 0.06%, 0.02%, and 0.008%). All wells containing compounds of Formula I or Formula II were loaded in duplicate. The plate was incubated for 2 hours at RT, then washed three times with 300 μL of PBS-0.05% Tween solution. Anti-GST HRP (GE Healthcare, #RPN1236) is diluted 1:20,000 in freshly prepared PBS, 0.1% Tween20, and 0.5% BSA was then added to the plate and the plate was incubated for 30 minutes. The plate was then washed five times with 300 μL of PBS-0.05% Tween solution. A solution of color reagents A (stabilized peroxide solution) and B (stabilized chrommogen solution) (R&D Systems, #DY999) is mixed in a 1:1 ratio and added to each well in a quantity of 80 μL. The wells were allowed to develop until control wells containing DMSO are blue (approximately 5-10 minutes). A solution of ELISA stop solution (1M sulfuric acid, 20 μL per well) was then added. Absorbance at 450 nM was read on a Tecan GeniosPro plate reader.

Assay: Fluorescence Polarization Assays: In another embodiment, Fluorescence Polarization ("FP") based assays may be used to detect and monitor ligand binding. Fluorescence polarization is a versatile laboratory technique for measuring equilibrium binding, nucleic acid hybridization, and enzymatic activity. Fluorescence polarization assays are homogeneous in that they do not require a separation step such as centrifugation, filtration, chromatography, precipitation, or electrophoresis. These assays are done in real time, directly in solution and do not require an immobilized phase. Polarization values can be measured repeatedly and after the addition of reagents since measuring the polarization is rapid and does not destroy the sample. Generally, this technique can be used to measure polarization values of fluorophores from low picomolar to micromolar levels.

Assay: Transactivation Assay: For determining the androgen receptor-dependent transcription, a cellular assay system was used, consisting of PC-3 cells (Kaighn et al., Invest. Urol. 17: 16-23, 1979), which express the human androgen receptor stably and recombinantly (full length, wild-type form, see Swiss-Prot Acc. No. P10275, Entry Version 159, Sequence Version 2). In addition, these PC3 cells contain a stably integrated reporter gene plasmid, which is based on the commercially available plasmid pGL4.14 (#E6691, Promega Corporation, Madison, Wis., USA) and contains the luciferase gene from the American firefly (Photinus pyralis) under the control of the MMTV promoter (Cato et al., EMBO J. 6: 363-368, 1987). These cells were propagated in routine cell culture at 37° C. and 5% CO2 in a medium containing 90% RPMI 1640 (Invitrogen GmbH, Darmstadt, Germany), 100 U penicillin, 100 μg/ml streptomycin (Invitrogen), 4 mM L-glutamine (Invitrogen), 10% fetal calf serum (FCS Serum Gold, PAA Laboratories GmbH, Cölbe, Germany), 600 μg/ml Geneticin (G418-sulphate, Invitrogen) and 10 μg/ml puromycin (Sigma Aldrich GmbH, Germany). For carrying out the transactivation assays, approx. 1000 cells per well were plated out in a 384-well cell culture plate in a medium that contained activated charcoal-treated calf serum (FCS Serum Gold, PAA Laboratories) at a concentration of 5% (v/v). The test substances were added in a concentration series from 5.12×10^−12 to 1×10^−5 M in the presence of 1×10^−1° R1881 (methyltrienolone). The test plates were incubated overnight at 37° C. and 5% CO2. After 16 hours, 15 μl of Steady Glo Lysis and Detection reagent (E2550, Promega Corporation, Madison, Wis., USA) was added per well and the luminescence was read in a Topcount Luminometer (PerkinElmer, Waltham, Mass., USA) for 4 seconds per well. The luminescence values obtained were normalized, wherein 100% corresponded to the effect of the unstimulated control (without R1881), and 0% corresponded to the effect of the stimulated control (R1881 plus DMSO instead of test substance).

Assay: TR-FRET Assay: The peptide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA ("Peptide A") was identified as a substrate for the TR-FRET assay by screening the 6× Histidine-tagged BIR2 domain and BIR3 domain of XIAP against a set of 29 peptides synthesized based on sequences reported by Sweeny et al. (Biochemistry, 2006, 45, 14740 14748). The peptides were labeled with the fluorescent tags FITC or TAMRA and Kd values were determined by fluorescence polarization assay. The sequence AVPIAQKSEK was identified as optimal for using in an assay. The peptide sequence was derivatized with biotin to provide AVPIAQKSEK-(Îµ-biotin)-OH 1:2 TFA as the substrate for the TR-FRET assay. Ten nanomolar of 6× Histidine-tagged BIR2 domain, corresponding to amino acids 124-240 of XIAP, or BIR3 domain, corresponding to amino acids 241-356 of XIAP, was mixed with 20 nM of the peptide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA, in the presence of 50 mM Tris-Cl, pH 7.5, 100 mM NaCl, 1 mM dithiothreitol (DTT) and 0.1 mg/mL bovine serum albumin (BSA). Following a 45 min. incubation at 37° C., Europium-Streptavidin and Allophycocyanin conjugated anti-Histidine antibody were added to a final concentration of 1.5 nM and 15 nM, respectively.

UniProt: P52792
Assay: Activation Assay: The final assay volume was 200 uL and the final buffer conditions used in this assay were as follows: 25 mM HEPES, 5 mM glucose, 1 mM ATP, 2 mM MgCl2, 1 mM NAD, 1 mM DTT, 8.5 U/mL G6PDH, 100 nM glucokinase, and 25 mM KCl. The buffer pH was 7.1. The mixture A was first made containing KCl, MgCl2, DTT and Glucose in HEPES buffer. The mixture B was made containing NAD and ATP. The test compound in DMSO solution, the mixture A, the mixture B and G6PDH were first mixed in a 96-well plate. Glucokinase was then added to initiate the reaction, and the absorbance at 340 nm was monitored every 5 mins. The activity of glucokinase was represented by the initial generation rate of glucose-6-phosphate, which was calculated by drawing the slope values from the absorbance changing curve at 340 nm vs. the time points. Compounds of this invention have an EC50 value as measured using the assay described herein of less than 50 μM.

Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P11309
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
