InChIKey: OIDHYGPWCABWGM-UHFFFAOYSA-N
Target: Aurora kinase A (SINGLE PROTEIN), Homo sapiens
UniProt: O14965
Assay: Enzyme Assay: The Aurora assays described here are performed on two Caliper Life Sciences systems: the LC3000 and the Desktop Profiler. These provide data on enzyme activity via measurement of the relative amounts of phosphorylated or unphosphorylated fluorescently labelled substrate peptide at the end of an enzymatic reaction. These different states of peptide are resolved by applying a potential difference across the sample. The presence of the charged phosphate group on the product (as opposed to the substrate) causes a different peptide mobility between the two peptides. This is visualized by excitation of the fluorescent label on the substrate and product peptides and represented as peaks within the analysis software.

UniProt: O75116
Assay: Kinase Inhibition Assay: The following assay protocol is for measuring the phosphorylation of a peptide substrate (FAM-KKLRRTLSVA-OH wherein FAM is carboxyfluorescein). The peptide is >98% purity by Capillary Electrophoresis. The peptide is phosphorylated by the protein kinase ROCK1 or ROCK2. The ROCK1 or ROCK2 enzyme, substrate, and cofactors (ATP and Mg2+) are combined in a well of a microtiter plate and incubated for 3 hours at 25° C. in the presence or absence of an inhibitor compound. At the end of the incubation, the reaction is quenched by the addition of an EDTA-containing buffer. The substrate and product are separated and quantified electrophoretically using the microfluidic-based LABCHIP® 3000 Drug Discovery System from Caliper Life Sciences (Hopkinton, Mass.).The components of the assay mixture are:100 mM HEPES, pH 7.50.1% BSA0.01% Triton X-1001 mM DTT10 mM MgCl210 μM Sodium Orthovanadate10 LM Beta-Glycerophosphate5 μM ATP (for ROCK1) or 7 μM ATP (for ROCK2)1% DMSO (from compound)1.25 μM FAM-KKLRRTLSVA-OH3 nM ROCK1 or 2.5 nM ROCK2 enzymeSubstrate and product peptides present in each sample are separated electrophoretically using the LABCHIP® 3000 capillary electrophoresis instrument. As substrate and product peptides are separated two peaks of fluorescence are observed. Change in the relative fluorescence intensity of the substrate and product peaks is the parameter measured reflecting enzyme activity. Capillary electrophoregramms (RDA acquisition files) are analyzed using HTS Well Analyzer software (Caliper Life Sciences, Hopkinton, Mass.). The kinase activity in each sample is determined as the product to sum ratio (PSR): P/(S+P), where P is the peak height of the product peptide and S is the peak height of the substrate peptide. For each compound, enzyme activity is measured at various concentrations (12 concentrations of compound spaced by 3× dilution intervals).

Assay: Recombinant Enzyme Assa: Compounds were assessed for their ability to inhibit the enzymatic activity of a recombinant form of Glutaminase 1 (GAC) using a biochemical assay that couples the production of glutamate (liberated by GAC) to glutamate dehydrogenase (GDH) and measuring the change in absorbance for the reduction of NAD+ to NADH. Substrate solution was prepared (50 mM Tris-HCl pH 8.0, 0.2 mM EDTA, 150 mM K2HPO4, 0.1 mg/ml BSA, 1 mM DTT, 20 mM L-glutamine, 2 mM NAD+, and 10 ppm antifoam) and 50 μL added to a 96-well half area clear plate (Corning #3695). Compound (2 μL) was added to give a final DMSO concentration of 2% at 2× the desired concentration of compound. Enzymatic reaction was started with the addition of 50 μL of enzyme solution (50 mM Tris-HCl pH 8.0, 0.2 mM EDTA, 150 mM K2HPO4, 0.1 mg/ml BSA, 1 mM DTT, 10 ppm antifoam, 4 units/ml GDH, 4 mM adenosine diphosphate, and 4 nM GAC) and read in a Molecular Devices M5 plate reader at 20° C. The plate reader was configured to read absorbance (λ=340 nm) in kinetic mode for 15 minutes. Data was recorded as milli-absorbance units per minute and slopes were compared to a control compound and a DMSO-only control on the same plate. Compounds with slopes less than the DMSO control were considered inhibitors and plate variability was assessed using the control compound.

Assay: Pharmacological Assay: For TLR8 and TLR7 activity testing, HEK-Blue human TLR8 or TLR7 cells (Invivogen, San Diego, Calif., USA) are used, respectively. These cells are designed for studying the stimulation of human TLR8 or TLR7 by monitoring the activation of NF-κB. A SEAP (secreted embryonic alkaline phosphatase) reporter gene is placed under the control of the IFN-b minimal promoter fused to five NF-κB and AP-1-binding sites. Therefore the reporter expression is regulated by the NF-κB promoter upon stimulation of human TLR8 or TLR7 for 20 hours. The cell culture supernatant SEAP reporter activity was determined using Quanti Blue kit (Invivogen, San Diego, Ca, USA) at a wavelength of 640 nm, a detection medium that turns purple/blue in the presence of alkaline phosphatase.

Target: Bromodomain-containing protein 4 (SINGLE PROTEIN), Homo sapiens
UniProt: O60885
Assay: Bromodomain Domain Binding Assay: A time-resolved fluorescence resonance energy transfer (TR-FRET) assay was used to determine the affinities of compounds of the Examples listed in Table 1 for each bromodomain of human BRD4. His-tagged first (BD1: amino acids K57-E168) and second (BD2: amino acids E352-E168) bromodomains of human BRD4 were expressed and purified. An Alexa647-labeled BET-inhibitor was used as the fluorescent probe in the assay. Compound dilution series were prepared in DMSO via a 3-fold serial dilution from 2.5 mM to 42 nM. Compounds were then diluted 6:100 in assay buffer (20 mM Sodium Phosphate, pH 6.0, 50 mM NaCl, 1 mM Ethylenediaminetetraacetic acid disodium salt dihydrate, 0.01% Triton X-100, 1 mM DL-Dithiothreitol) to yield 3× working solutions. Six microliters (L) of the working solution was then transferred to white, low-volume assay plates (Costar #3673). A 1.5× assay mixture containing His-tagged bromodomain, Europium-conjugated anti-His antibody (Invitrogen PV5596) and the Alexa-647-conjugated probe molecule was also prepared. Twelve L of this solution were added to the assay plate to reach a final volume of 18 L. The final concentration of 1× assay buffer contains 2% DMSO, 50 M-0.85 nM compound, 8 nM His-tagged bromodomain, 1 nM Europium-conjugated anti-His-tag antibody and 100 nM or 30 nM probe (for BDI or BDII, respectively). After a one-hour incubation at room temperature, TR-FRET ratios were determined using an Envision multilabel plate reader (Ex 340, Em 495/520).

Target: Kappa-type opioid receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P41145
Assay: Radioligand Dose-Displacement Binding Assay: Radioligand dose displacement assays used 0.4 nM [3H]-U69,593 (GE Healthcare, Piscataway, N.J.; 40 Ci/mmole) with 15 μg membrane protein (recombinant κ opioid receptor expressed in HEK 293 cells; in-house prep) in a final volume of 200 μl binding buffer (5% DMSO, 50 mM Trizma base, pH 7.4). Non-specific binding was determined in the presence of 10 μM unlabeled naloxone or U69,593. All reactions were performed in 96-well polypropylene plates for 1 hr at a temperature of about 25° C. Binding reactions were terminated by rapid filtration onto 96-well Unifilter GF/C filter plates (Perkin Elmer, Shelton, Conn.) presoaked in 0.5% polyethylenimine (Sigma). Harvesting was performed using a 96-well tissue harvester (Perkin Elmer, Shelton, Conn.) followed by five filtration washes with 2001 ice-cold binding buffer. Filter plates were subsequently dried at 50° C. for 1-2 hours.
