Assay: Biological Assay: TAK1-TAB1 Binding Inhibitory Potency: The ability of candidate compounds to interact with TAK1-TAB1 is quantitated by a competitive binding assay using the LanthaScreen technology developed by Life Technologies. This assay is based on the binding of a proprietary, Alexa Fluor 647-labeled, ATP-competitive kinase inhibitor (kinase tracer-236) to the TAK1-TAB1 construct in presence of a europium-conjugated antibody, resulting in a FRET (fluorescence resonance energy transfer) signal. Displacement of the kinase tracer by compound results in a lower emission ratio upon excitation of the europium chelate. Candidate compounds are designed as potential irreversible inhibitors of TAK1-TAB1, capable of ligating to an active site cysteine residue. The time dependent nature of irreversible inhibition is investigated by performing the binding assay with and without a pre-incubation of compound and TAK1-TAB1. An increase in potency in the pre-incubated assay suggests the candidate compound could b of 10 nM TAK1-TAB1, 2 nM Eu-anti-his antibody, and 100 nM kinase tracer-236 using a 384-well plate format. Background signal is defined in the absence of TAK1-TAB1 and uninhibited signal is defined in the presence of vehicle (2% DMSO) alone. Compounds were evaluated in an 11 point dose-response ranging from 20 uM to 0.34 nM. The binding assays are performed under two conditions to evaluate time dependence of inhibition. For the pre-incubation assay, TAK1-TAB1 and Eu-anti-his antibody are preincubated with compound or vehicle for two hours prior to the addition of kinase tracer. The non-preincubated assay is run in which TAK1-TAB1 and Eu-anti-his antibody are added to a mixture of compound and kinase tracer. IC50 values of compounds are determined using a 4 parameter logistical fit of emission ratio as a function of the concentration of compound.

Assay: Radioligand Binding Assay: Radioligand binding assays at A1, A2A, and A3ARs were performed according to the procedures described previously. Each tube in the binding assay contained 100 uL of membrane suspension (20 ug of protein), 50 pt of a stock solution of agonist radioligand, and 50 uL of increasing concentrations of the test ligands in Tris-HCl buffer (50 mM, pH 7.5) containing 10 mM MgCl2. Nonspecific binding was determined using a final concentration of 10 uM NECA, a non-specific agonist, diluted with the buffer.The mixtures were incubated at 25° C. for 60 min. Binding reactions were terminated by filtration through Whatman GF/B filters under a reduced pressure using a MT-24 cell harvester (Brandell, Gaithersburg, Md.).

UniProt: P25090
Assay: Biological Assay: The ability of a compound to block the intracellular release of calcium mediated by PK1 in RBL2H3 cells expressing human PKR1 receptors is determined as a measure of the compound's antagonist activity in vitro.Approximately 10,000 cells per assay well are seeded in normal culture medium in a 384 well plate (Corning). Twenty-four hours after seeding, the cells are loaded with a calcium sensitive fluorescent dye by replacing the culture medium with assay buffer (1× Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH 7.4) containing 1 mM probenecid and 1× Calcium 5 Reagent (Molecular Devices). Cells are incubated at 37° C. for 1 hour to allow for dye uptake.To test for antagonist activity, test compounds at a final concentration range between 0.32 nM-10 μM (diluted in assay buffer) are added to the assay wells and allowed to incubate for 10 minutes prior to stimulation with PK1. After incubation with test compounds the assay plate is placed in a FLIPR Tetra (Molecular Devices) and PK1 (diluted in assay buffer) is added at the determined EC80 concentration (final). Ligand-dependent changes in intracellular calcium levels are determined by measuring changes in fluorescence of the dye at 525 nM following to excitation at 485 nM.

Assay: Ligand KI Assay: The labeled ligand specifically binds BRD4-1 and BRD4-2 and can be displaced by a small molecule inhibitor that shares a similar or overlapping binding site. BRD4-I and BRD4-2 were expressed and purified from Escherichia coli as N-terminal His6, tagged proteins. A Eu-cryptate labeled anti-His antibody (Perkin Elmer) was used to specifically bind BRD4. Binding of BRD4 to the labeled probe/ligand resulted in an increase in FRET signal whereas displacement of this labeled ligand from BRD4 with a small molecule inhibitor resulted in a decrease in FRET signal. Assays were performed in 50 mM Hepes (pH 7.5), 150 mM NaCl, 0.1 mg/ml BSA, 0.01% (v/v) Brij, 0.5% (v/v) DMSO and 10 nM labeled ligand at the following concentrations for each BRD4 isoform: 2 nM BRD4-1 and 0.5 nM BRD4-2. After an assay reaction time of 60 minutes at 25° C., binding was measured with 2 nM Eu-cryptate labeled anti-His antibody. TR-FRET signal was detected on an Envision plate reader (Ex: 320 nm; Em: 615/665 nm; 100 us delay and 200 us read window). Data were normalized based on a positive (2 uM I-BET) and negative (DMSO) controls and IC50 values were calculated from the fit of the dose-response curves to a four-parameter equation. All IC50 values represent geometric mean values of a minimum of four determinations. The IC50 values were converted to Ki values (dissociation constant for BRD4-inhibitor complex) using the Cheng and Prusoff equation for a competitive inhibitor mode of action.

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.

Twenty-four hours after seeding, the cells are loaded with a calcium sensitive fluorescent dye by replacing the culture medium with assay buffer (1× Hanks buffered saline, 25 mM HEPES, 0.1% w/v fatty acid free BSA (bovine serum albumin), pH 7.4) containing 1 mM probenecid and 1× Calcium 5 Reagent (Molecular Devices). Cells are incubated at 37° C. for 1 hour to allow for dye uptake.To test for antagonist activity, test compounds at a final concentration range between 0.32 nM-10 μM (diluted in assay buffer) are added to the assay wells and allowed to incubate for 10 minutes prior to stimulation with PK1. After incubation with test compounds the assay plate is placed in a FLIPR Tetra (Molecular Devices) and PK1 (diluted in assay buffer) is added at the determined EC80 concentration (final). Ligand-dependent changes in intracellular calcium levels are determined by measuring changes in fluorescence of the dye at 525 nM following to excitation at 485 nM.

Target: Genome polyprotein (SINGLE PROTEIN), Hepatitis C virus genotype 1b (isolate Japanese) (HCV)
UniProt: P26662
Assay: ELISA-Based Assay: Measurement of inhibition by compounds was performed using the HCV replicon system. Several different replicons encoding different HCV genotypes or mutations were used. In addition, potency measurements were made using different formats of the replicon assay, including different ways of measurements and different plating formats. See Jan M. Vrolijk et al., A replicons-based bioassay for the measurement of interferons in patients with chronic hepatitis C, 110 J. VIROLOGICAL METHODS 201 (2003); Steven S. Carroll et al., Inhibition of Hepatitis C Virus RNA Replication by 2'-Modified Nucleoside Analogs, 278(14) J. BIOLOGICAL CHEMISTRY 11979 (2003). However, the underlying principles are common to all of these determinations, and are outlined below.Stable neomycin phosphotransferase encoding replicons-harboring cell lines were used, so all cell lines were maintained under G418 selection prior to the assay. Potency was determined using a cell ELISA assay with an antibody to the replicons encoded NS3/4a protease.
