Target: Methionine aminopeptidase 2 (SINGLE PROTEIN), Homo sapiens
UniProt: P50579
Assay: Enzymatic Screening Assay: The enzymatic test is a test in two steps.In a first step, it consists in placing in contact the compound according to the invention, the dialysed MetAP2 protein and the substrate (Met-Pro-Arg-pNa peptide synthesized by Neosystem), the N-terminal methionine of which can be cleaved with MetAP2, and which bears at the C-terminal end a para-nitroaniline (pNa) chromophore, which can itself be released by another peptidase only when the N-terminal methionine has been cleaved beforehand.Consequently, the second step consists in reacting the peptides cleaved in the preceding step with a second peptidase in order to release the chromophore. The peptidase used in this second step is cathepsin, which comes from the TagZyme DAPase kit (Quiagen, 34366).The MetAP2 activity is proportional to the amount of para-nitroaniline released, which is measured by absorbance at 405 nm.

Assay: Functional Assay: The functional activity of compounds of the formula (I) was determined by measuring changes in intracellular calcium concentration using a Ca2+-sensitive fluorescent dye. The changes in fluorescent signal were monitored by a fluorescence plate reader, either a FLIPR (Molecular Devices) or FDSS (Hamamatsu). Increases in intracellular Ca2+ concentration were readily detected upon activation with icilin.At 24 hrs prior to assay, HEK293 cells stably expressing canine TRPM8 were seeded in culture medium in black wall, clear-base poly-D-lysine coated 384-well plates (BD Biosciences, NJ, USA) and grown overnight in 5% CO2 at 37° C. On assay day, growth media was removed and cells were loaded with Calcium 3 Dye (Molecular Devices) for 35 min at 37° C., under 5% CO2 and then for 25 min at room temperature and atmosphere. Subsequently, cells were tested for agonist-induced increases in intracellular Ca2+ levels using FLIPR or FDSS. Cells were challenged with a compound of the Formula (I) (at varying concentrations) and intracellular Ca2+ was measured for 5 min prior to the addition of icilin to all wells to achieve a final concentration that produces approximately an 80% maximal response. EC50 or IC50 values for compounds of the present invention were determined from eight-point dose-response studies.

Cover with a new adhesive strip and incubate 2 hours at room temperature. Repeat the aspiration/wash as in step 2 of Plate Preparation. Add 100 μL of the working dilution of Streptavidin-HRP to each well. Cover the plate and incubate for 20 minutes at room temperature. Avoid placing the plate in direct light. Repeat the aspiration/wash as in step 2. Add 100 μL of Substrate Solution to each well. Incubate for 20 minutes at room temperature. Avoid placing the plate in direct light. Add 50 μL of Stop Solution to each well. Gently tap the plate to ensure thorough mixing. Determine the optical density of each well immediately, using a microplate reader set to 450 nm. If wavelength correction is available, set to 540 nm or 570 nm. If wavelength correction is not available, subtract readings at 540 nm or 570 nm from the readings at 450 nm. This subtraction will correct for optical imperfections in the plate. Readings made directly at 450 nm without correction may be higher and less accurate.

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: In Vitro Enzymatic BACE FRET Assay: The assay buffer used in this screen is 0.05 M acetate, pH 4.2, 10% DMSO final, 100 uM genapol (which is a nonionic detergent, below its Critical Micelle Concentration). The Beta Secretase enzyme (0.2 nM) is pre-incubated for one hour with inhibitors, typically in about 1 uL of DMSO according to a serial dilution, are added thereto. This assay is effectively started by the addition of FRET substrate (50 nM) and the combination is incubated for one hour.

The FRET substrate is a peptide with commercially available fluorophore and quencher, on opposite sides of the BACE cleavage site. Proteolytic cleavage of the FRET substrate releases quenching of fluorescence (excitation 488 nm and emission 425 nm).

Assay: Biochemical HTRF Assay: The ability of compounds to inhibit the activity of JAK1, JAK2, JAK3, and Tyk2 was measured using a recombinant purified GST-tagged catalytic domain for each enzyme (Invitrogen JAK1 #M4290, JAK2 #M4290, JAK3 #M4290, Tyk2 #M4290) in an HTRF format biochemical assay. The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 μL of 1.11× enzyme and 1.11× substrate in 1× assay buffer (Invitrogen kinase buffer # PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at ambient temperature to allow compound binding to equilibrate. After equilibration, 2 μL of 10×ATP in 1× assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at ambient temperature for 120 minutes. At the end of the incubation, 20 μL of 2× stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction.

Compound (SMILES): COCCNc1cc(NC(=O)N2CCCc3cc(CN4CCCC45COC5)c(C=O)nc32)ncc1C#N
InChIKey: NQUXUVXCMJRKGW-UHFFFAOYSA-N
Target: Fibroblast growth factor receptor 4 (SINGLE PROTEIN), Homo sapiens
UniProt: P22455
Assay: Biochemical Kinase Assay: Liquid handling and incubation steps were done on an Innovadyne Nanodrop Express equipped with a robotic arm (Thermo CatX, Caliper Twister II) and an incubator (Liconic STX40, Thermo Cytomat 2C450). The assay plates were prepared by addition of 50 nl per well of compound solution in 90% DMSO. The kinase reactions were started by stepwise addition of 4.5 ul per well of peptide/ATP-solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% Tween20, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 uM sodium orthovanadate, 16 mM MgCl2, 1122 uM ATP, 4 uM peptide (5-Fluo-Ahx-KKKKEEIYFFFG-NH2, Biosyntan GmbH) and 4.5 ul per well of enzyme solution (50 mM HEPES, pH 7.5, 1 mM DTT, 0.02% Tween20, 0.02% BSA, 0.6% DMSO, 10 mM beta-glycerophosphate, and 10 uM sodium orthovanadate, 16 mM MgCl2, 6 nM FGFR4 (GST-FGFR4(388-802), produced in-house by expression in insect cells and affinity chromatography). Kinase reactions were incubated at 30° C. for 60 minutes and subsequently terminated by addition of 16 ul per well of stop solution (100 mM HEPES pH 7.5, 5% DMSO, 0.1% Caliper coating reagent, 10 mM EDTA, and 0.015% Brij35).

InChIKey: KGCJPLPXHXENIS-UHFFFAOYSA-N
Target: Dihydrolipoyl dehydrogenase (SINGLE PROTEIN), Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
UniProt: P9WHH9
Assay: Inhibition Assay: The assay was performed in a manner similar to that described in Bryk et al., Biochemistry (2010) 49:1616-1627 and modified for an online robotics screening system.A solution containing Lpd (100 nM) and 100 mM sodium phosphate buffer (pH 7.0) was prepared. Another solution containing the substrate lipoamide (2 mM), 100 mM sodium phosphate buffer (pH 7.0), EDTA (4 mM), and NADH (200 uM) was also prepared. The detection reagent, DTNB was dissolved in DMSO and diluted to a concentration of 375 uM with a 100 mM sodium phosphate buffer (pH 7.0).4 uL/well of Lpd solution was dispensed into 1536-well clear bottom plates. Next, 50 nL of each test compounds (1 mM dissolved in DMSO) was added into each well. After one hour of incubation, 4 uL/well of lipoamide (LPA) solution was added, so that in each well, the concentrations of Lpd, LPA, and the test compound were 50 nM, 1 mM, and 6.25 uM, respectively.
