Assay: B-RAF (V600E) Kinase Assay: In a dilution series 10 uL/well of test substance solution are placed in a multiwell plate. The dilution series is selected so that generally a range of concentrations of 2 uM to 0.119 nM or 0.017 nM is covered. If necessary the initial concentration of 2 uM is changed to 50 uM, 10 uM or 0.4 uM or 0.2857 uM and further dilution is carried out accordingly. The final concentration of DMSO is 5%. 10 uL/well of the B-Raf (V600E)-kinase solution are pipetted in (containing 0.5 ng B-Raf (V600E)-kinase (e.g. from Upstate) in 20 mM Tris-HCl pH 7.5, 0.1 mM EDTA, 0.1 mM EGTA, 0.286 mM sodium orthovanadate, 10% glycerol, 1 mg/mL bovine serum albumin, 1 mM dithiothreitol) and the mixture is incubated for 1 h at RT under with shaking. The kinase reaction is started by the addition of 20 uL/well ATP solution [final concentration: 250 uM ATP, 30 mM Tris-HCl pH 7.5, 0.02% Brij, 0.2 mM sodium orthovanadate, 10 mM magnesium acetate, 0.1 mM EGTA, phosphatase cocktail (Sigma, #P2850, dilution recommended by the manufacturer)] and 10 uL/well MEK1 solution [containing 50 ng biotinylated MEK1 (prepared from purified MEK1 according to standard procedure, e.g. with EZ-Link Sulpho-NHS-LC-Biotin reagent, Pierce, #21335)] and carried out for 60 min at RT with constant shaking. The reaction is stopped by the addition of 12 uL/well of a 100 mM EDTA solution and incubation is continued for a further 5 min. 55 uL/well of the reaction solution are transferred into a streptavidin-coated plate (e.g. Streptawell HighBond, Roche, #11989685001) and shaken gently for 1 h at RT, in order to bind biotinylated MEK1 to the plate. After elimination of the liquid the plate is washed five times with 200 uL/well of 1Ã¿PBS and 100 uL/well solution of primary antibody plus europium-labelled secondary antibody [Anti Phospho-MEK (Ser217/221), Cell Signaling, #9121 and Eu-N1 labelled goat-anti-rabbit antibody, Perkin Elmer, #AD0105] is added, the primary antibody is diluted 1:2000 and the secondary antibody is diluted to 0.4-0.5 ug/mL in Delfia Assay Buffer (Perkin Elmer, #1244-111). After 1 h shaking at RT the solution is poured away and washed five times with 200 uL/well Delfia Wash Buffer (Perkin Elmer, #4010-0010/#1244-114). After the addition of 200 uL/well Enhancement Solution (Perkin Elmer, #4001-0010/#1244-105) the mixture is shaken for 10 min at RT and then measured in a Wallac Victor using the program "Delfia Time Resolved Fluorescence (Europium)". IC50 values are obtained from these dosage-activity curves using a software program (GraphPadPrizm).

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.

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: YO-PRO Assay: HEK cells stably expressing P2X7 were used to screen drugs using the YO-PRO1 assay. Cells were grown to confluency in adherent culture at 37° C. in a humidified 5% CO2 incubator (split ⅕ every 3-4 days with DMEM, 10% FCS, 1% Penicillin/Streptomycin, 250 μg/ml Geneticin). Adherent cells were detached by incubation with Trypsine (1 ml per 165 cm2 dish) for 2 minutes, then washed off with 10 ml PBS (without Mg2+ and Ca2+), and resuspended in DMEM, 10% FCS, 1% Penicillin/Streptomycin, no Geneticin. 10,000 cells per well (48 hours before the assay) or 25,000 cells per well (Vi-cell XR (Beckman Coulter) (24 hours before the assay) in 50 μl full medium were seeded on 384-well black-wall, clear bottom plates, that were coated before with 10 μl per well Poly-L-Lysine, incubated for 30-60 minutes at 37° C. and washed once with PBS. Medium was removed from cells and 50 μl of assay buffer containing 0.5 μM YO-PRO-1 was added into the wells. Solutions of antagonist compounds were prepared by serial dilutions of a 10 mM DMSO solution of the antagonist into PBS using a BioMek (Beckman Coulter). Each concentration was performed in duplicate. For IC50 measurements 10 concentration points were measured (10 μM being the highest concentration followed by 9 serial dilution steps ⅓). The cells were incubated with the antagonists of the present invention together with ATP at a final concentration of 250 μM for 90 minutes. During this time period, four time points were taken. Each time point comprised the average of several measurements made within a few seconds. Fluorescence was measured in the FLIPR tetra (Molecular Devices) using the filters appropriate for YO-PRO-1 fluorescence (excitation485/20, emission 530/25).
