UniProt: Q13464
Assay: In Vitro Assay: The effectiveness of compounds of the present invention as ROCK inhibitors can be determined in a 30 μL assay containing 20 mM HEPES, pH 7.5, 20 mM MgCl2, 0.015% Brij-35, 4 mM DTT, 5 μM ATP and 1.5 μM peptide substrate (FITC-AHA-AKRRRLSSLRA-OH). Compounds were dissolved in DMSO so that the final concentration of DMSO was <2%, and the reaction was initiated with Rho kinase variants. After incubation, the reaction was terminated by the addition of EDTA and the phosphorylated and non-phosphorylated peptides separated using a LABCHIP® 3000 Reader (Caliper Life Sciences). Controls consisted of assays that did not contain compound, and backgrounds consisted of assays that contained enzyme and substrate but had EDTA from the beginning of the reaction to inhibit kinase activity. Compounds were tested in dose-response format, and the inhibition of kinase activity was calculated at each concentration of compound. The inhibition data were fit using a curve-fitting program to determine the IC50; i.e., the concentration of compound required to inhibit 50% of kinase activity.

Assay: Recombinant SSAO/VAP-1 Inhibition Assay in Rat Fat: Abdominal fat from BALB/c mice, Wistar or Sprague Dawley rats, which are tissues enriched with SSAO/VAP-1-were surgically removed. For every gram of animal abdominal fat tissue, 1 mL of 0.1 M NaPO4 buffer (pH 7.4) was added. Tissues were homogenized using IKA Ultra-Turrax T 10 homogenizer for 3 min, homogenate was centrifuged for 15 min at 3000×g. The middle layer (clear supernatant) was removed without disturbing the top layer (high fat content) or the debris on the bottom of the tube. SSAO/VAP-1 activity was determined by checking the fluorescent signal. Km/Vmax values were determined and the fat homogenate was aliquoted and stored at −80 °C until assays were performed. Assay was performed in a similar fashion as for human SSAO/VAP-1 (Example 5) except, the substrate (benzylamine) concentrations used for mouse fat homogenate and rat fat homogenate were 80 μM and 30 μM respectively: Briefly, in a standard 96 well plate assay 50 μL of purified human SSAO/VAP-1 (0.25 μg/mL) in 0.1 M NaPO4 buffer (pH 7.4) was added into each well. Test compounds were dissolved in DMSO and tested in a Concentration Response Curve (CRC) with 4-9 data points, typically in the micromolar or nanomolar range after incubation with human SSAO/VAP-1 for 30 min at 37 °C. After 30 min incubation, 50 μL of the reaction mixture containing 600 μM benzylamine (Sigma Aldrich), 120 μM Amplex Red (Sigma Aldrich) and 1.5 U/mL horseradish peroxidase (Sigma Aldrich) prepared in 0.1 M NaPO4 buffer (pH 7.4) were added to the corresponding well. The fluorescence unit (RFU) was read every 2.5 min for 30 min at 37 °C. excitation 565 nm and emission 590 (Optima; BMG labtech). The slope of the kinetics for each well was calculated using MARS data analysis software (BMG labtech) and this value was used to deduce the IC50 value (Dotmatics).

Target: Serine/threonine-protein kinase pim-3 (SINGLE PROTEIN), Homo sapiens
UniProt: Q86V86
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

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.

Assay: Enzyme Assay: Compounds for testing were diluted in DMSO to 50 fold the final concentration and a ten point three fold dilution series was made. The compounds were diluted in assay buffer (50 mM HEPES, pH 7.4, 100 mM KCl, 0.001% Tween-20, 0.05% BSA, 20 uM TCEP) to 6 fold their final concentration. The HDAC enzymes (purchased from BPS Biosciences) were diluted to 1.5 fold their final concentration in assay buffer. The tripeptide substrate and trypsin at 0.05 uM final concentration were diluted in assay buffer at 6 fold their final concentration. The final enzyme concentrations used in these assays were 3.3 ng/ml (HDAC1), 0.2 ng/ml (HDAC2), 0.08 ng/ml (HDAC3) and 2 ng/ml (HDAC6). The final substrate concentrations used were 16 uM (HDAC1), 10 uM (HDAC2), 17 uM (HDAC3) and 14 uM (HDAC6).Five ul of compounds and 20 ul of enzyme were added to wells of a black, opaque 384 well plate in duplicate. Enzyme and compound were incubated together at room temperature for 10 minutes. Five ul of substrate was added to each well, the plate was shaken for 60 seconds and placed into a Victor 2 microtiter plate reader. The development of fluorescence was monitored for 60 min and the linear rate of the reaction was calculated. The IC50 was determined using Graph Pad Prism by a four parameter curve fit.

InChIKey: FYATUSPSVPIDFE-UHFFFAOYSA-N
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.)
