Assay: In Vitro Canine TRPM8 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-TM (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-TM 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. Curves were generated using the average of quadruplicate wells for each data point.

UniProt: Q13547
Assay: Enzyme Assay: Enzyme activity of HDAC1,3 is determined using the substrate Ac-Lys-Tyr-Lys(Ac)-AMC while the enzyme activity of HDAC6 is assayed using the substrate Boc-lys(Ac)-AMC. The reaction is carried out in flat-bottom, 96-well, or 384-well microplates. After the substrate was deacetylated by HDACs, the product AMC which was obtained from hydrolysis by trypsin can generate fluorescence signal. Measurement is taken in using an multilabe plate reader a 355 nm excitation filter and a 460 nm emission filter. The initial rate of fluorescence should accurately reflect the rate of product formation and enzyme activity. Sample processing: The sample was dissolved in DMSO and kept at a low temperature. DMSO in the final system is limited under a low concentration which won't affect the enzyme activity.

Assay: Time-Resolved Fluorescence Resonance Energy Transfer Assay: Compounds disclosed herein were tested for inhibition of Btk kinase activity in an assay based on time-resolved fluorescence resonance energy transfer methodology. Recombinant Btk was pre-incubated with the compounds disclosed herein at room temperature for 1 hour in an assay buffer containing 50 mM Tris pH7.4, 10 mM MgCl2, 2 mM MnCl2, 0.1 mM EDTA, 1 mM DT, 20 nM SEB, 0.1% BSA, 0.005% tween-20. The reactions were initiated by the addition of ATP (at the concentration of ATP Km) and peptide substrate (Biotin-AVLESEEELYSSARQ-NH2). After incubating at room temperature for 1 h, an equal volume of stop solution containing 50 mM HEPES pH7.0, 800 mM KF, 20 mM EDTA, 0.1% BSA, Eu cryptate-conjugated p-Tyr66 antibody and streptavidin-labeled XL665 was added to stop the reaction. Plates were further incubated at room temperature for 1 hour, and then the TR-FRET signals (ex337 nm, em 620 nm/665 nm) were read on BMG PHERAstar FS instrument. The residual enzyme activity in presence of increasing concentrations of compounds was calculated based on the ratio of fluorescence at 615 nm to that at 665 nm. The IC50 for each compound was derived from fitting the data to the four-parameter logistic equation by Graphpad Prism software.

UniProt: Q9NR97
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.

Assay: Cell Based Assay: TRKA co-expressed with p75: The assays are based upon DiscoveRx's proprietary Enzyme Fragment Complementation (EFC) technology. In the case of the TRK cell lines, the enzyme acceptor (EA) protein is fused to a SH2 protein and the TRK receptor of interest has been tagged with a Prolink tag. Cryopreserved PathHunter cells are used from either in-house produced batches or bulk batches bought directly from DiscoveRx. Cryopreserved cells are resuscitated, spun 1000 rpm for 4 min to remove freezing media, and resuspended in MEM+0.5% horse serum (both Invitrogen) to 5e^5 cells/ml. The cells are then plated using a Multidrop into Greiner white tissue culture treated plates at 20 μl/well and incubated for 24 h at 37 °C., 5% CO2, high humidity. On the day of the assay, the cell plates are allowed to cool to room temperature for 30 min prior to the assay. 4 mM stock solutions of test compounds are prepared and serially diluted in 100% DMSO. A standard curve using the compound of Example 135, WO2005/116035 at a top concentration of 150 μM is also prepared on each test plate. High percentage effect (HPE) is defined by 150 μM of the compound of Example 135, WO2005/116035 and 0% effect (ZPE) is defined by 100% DMSO. Plates containing 1 μl of serially diluted compound, standard and HPE/ZPE are diluted 1/66 in assay buffer (PBS minus Ca2+, minus Mg2+ with 0.05% pluronic F127) using a Wellmate. Using a Platemate Plus, 5 μl of 1/66 diluted test compounds is then transferred to the cell plate and allowed to reach equilibrium by incubating for 30 min at room temperature before addition of agonist stimulus: 10 μl/well of 2 nM (0.571 nM FAC) of the cognate neurotrophin (Peprotech) diluted in agonist buffer (HBSS with 0.25% BSA). Final assay concentration of the test compounds is 8.66 μM, (the compound of Example 135, WO2005/116035 FAC is 0.325 μM). The plates are left at room temperature for a further 2 hours before addition of 10 μl of the DiscoveRx PathHunter detection reagent (made up by adding 1 part Galacton Star, 5 parts Emerald II and 19 parts Cell Assay Buffer as per the manufacturer's instructions). After reagent addition, plates are covered and incubated at room temperature for 60 minutes. Luminescence signal is read using an Envision.

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.

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.

Target: Leukotriene C4 synthase (SINGLE PROTEIN), Homo sapiens
UniProt: Q16873
Assay: In Vitro hLTC4 Synthase Enzyme Assay (Test A): In the assay, LTC4 synthase catalyses the reaction where the substrate LTA4 is converted to LTC4. Recombinant human LTC4 synthase is expressed in Piccia pastoralis and the purified enzyme is dissolved in 25 mM tris-buffer pH 7.8 supplemented with 0.1 mM glutathione (GSH) and stored at −80 °C. In order to obtain IC50-values for the compounds, the following procedure was used: A volume (24 μL) of 0.25 g/mL LTC4 synthase in 75 mM tris (pH ~8.5), 0.5 mM MgCl2 and 3 mM GSH was preincubated for 10 min with 0.5 μL of compound of interest in DMSO at ten different concentrations, typically in the range 10^−9,5-10^−5 M as well as with DMSO only. The buffer is used as background. Runs are performed in duplicates. The enzymatic reaction is initiated by addition of 0.5 μL LTA4 in diglyme (final assay concentration 8 μM). The reaction is stopped after 1 min by addition of double the reaction volume of a stop solution (MeOH:H2O:acetic acid 70:30:1).

Assay: In Vitro Assay: CHO-K1 CXCR7 b-arrestin cells are detached from culture dishes with a cell dissociation buffer (Invitrogen, #13151-014) and collected in growing medium (F12 HAMS 90% (v/v)/FCS 10% (v/v), Penicilin/streptomycin 1% (v/v)). 5000 cells per well (in 20 μl) are seeded in a 384 well plate (white-walled, clear bottom; BD Falcon #353274). The plate is incubated at 37° C./5% CO2 for 24 hours. Medium is then replaced by 20 μl OPTIMEM (Invitrogen #31985) for 3 to 4 hours. Test compounds are dissolved at 10 mM in DMSO and serially diluted in DMSO to 200× of the final concentration for dose response curves. Compounds are then diluted 1:33.3 in HBSS1×. 5 μl/well of HBSS1×/20 mM HEPES/0.2% BSA are added to the assay plate followed by addition of 5 μl/well of diluted compounds. CXCL12 (Peprotech #300-28A) may be used as a reference agonist. The plate is incubated for 90 minutes at 37° C. 12 μl of detection reagent (Path Hunter Detection Kit, DiscoveRx, #93-0001) is transferred to the assay plate and to the plate is incubated for 1 hour at room temperature. Luminescent signal is read in a microplate reader (FLUOstar Optima, bmg).
