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.

Assay: Inhibition Assay: PI3 kinases catalyse the phosphorylation of phosphatidylinositol 4,5-biphosphate (PIP2) to phosphatidylinositol 3,4,5-triphosphate (PIP3) in the presence of ATP and Mg2+ ions. The PIP3 product can be detected by displacement of biotin-PIP3 from energy transfer complexes consisting of europium labelled anti-GST monoclonal antibody, a GST-tagged Pleckstrin homology (PH) domain, biotinylated PIP3 and streptavidin-allophycocyanin (APC) by the time-resolved fluorescence resonance energy transfer (TR-FRET) (HTRF® PI3K enzyme assay, Millipore). Excitation (330 nm) of europium in the complex results in an energy transfer to the APC and a fluorescent emission at 665 nm although europium itself emits at its characteristic 620 nm. The PIP3 product formed by PI3K activity displaces biotin-PIP3 from the complex and results in a loss of energy transfer (decreasing signal). The compound to be tested was added, at the desired final concentrations, to a mixture of PIP2 substrate and recombinant PI3 kinase α, δ or γ enzymes (Millipore), and the mixture incubated for 2 hr at RT. Following this incubation period, ATP (20 μM) was added to the enzyme/compound/PIP2 substrate mixture and the resulting mixture was incubated for 30 min at RT. A stopping solution containing biotinylated PIP3 and the detection mix containing the GST tagged GRP1 pleckstrin homology (PH) domain and fluorophores were then added and the mixture was incubated at RT for 15-18 hr, prior to detection in a fluorescence microplate reader (Varioskan® Flash, ThermoFisher Scientific).

Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P11309
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): 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 384-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 22-point dosing curve having a high dose of 1 μM. A reference compound was included on each assay plate [Costar 3658] in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The Reaction Buffer consisted of 45 mM Hepes, pH 7.0, 15 mM NaCl, and 1 mM MgCl. The quench/detection buffer consisted of 50 mM Tris, 100 mM NaCl, 0.05% BSA, 0.1% Tween and 3 mM EDTA. Biotinylated BAD peptide (Biopeptide), 10 mM ATP (Sigma), Labeled p-BAD (S112) mAb (Cell Signalling and Perkin Elmer) [with 0.05% BSA and 2 mM DTT added] streptavidin:Allophycocyanin [Perkin Elmer].

Assay: Radioligand Binding Assay: Assessments of compound binding to human MC5R (hMC5R)) by displacement of an 125I-labeled NDP-MSH receptor ligand peptide were performed essentially as described in the data sheets produced by Perkin Elmer to accompany their frozen hMC5R membranes (Perkin Elmer catalog number RBXMC5M400UA). [125I] NDP-MSH: Radiolabeled in House and Purified by HPLC: Na125I (0.5 mCi, 17.4 Ci/mg) was added to 50 μL sodium phosphate (50 mM, pH 7.4) in an eppendorf tube precoated with IODOGEN. After incubation for 10 mins the phosphate buffer containing the iodine was added to NDP-MSH (10 μl at 1 mg/mL) in a separate eppendorf tube. This was incubated for a further 10 mins. The iodinated NDP-MSH was purified by HPLC on a Zorbax SB 300 column using solvent A: 0.05% TFA and solvent B: 90% acetonitrile 0.045% TFA with a linear gradient, 0-67% B over 60 mins. The 125I NDP-MSH eluted at 52 mins after the unlabeled starting material (48 min) and was counted and stored in the freezer. It was used within 48 hrs, as radioactive decay and ligand decomposition resulted in greatly reduced specific binding observed after 72 hrs. Incubation buffer: 25 mM HEPES-KOH (pH 7.0), 1.5 mM CaCl2, 1 mM MgSO4, 0.1 M NaCl, 1 mM 1,10-phenanthroline, and 1 Complete™ protease inhibitor tablet/100 mL (Roche, catalog number 1873580). Perkin Elmer frozen hMC5 membranes: catalog number RBXMC5M400UA, 0.4 mL/vial; 400 microassays/vial, 0.78 mg/mL protein concentration. Vials of frozen membranes were thawed rapidly immediately before use, diluted with binding buffer and vortexed. Resuspended membranes were kept on ice until they were added to the wells of the plate. Assays were performed in 96 well polypropylene plates. Membranes (0.78 μg 40 μL of a 1:40 dilution in incubation buffer) were added to [125I] NDP-MSH (0.84 nM; 2200 Ci/mmol) and test compounds in a total volume of 140 μL. This was incubated for 1 hr at 37° C. Non-specific binding was determined with 3 mM NDP-MSH. Plates were filtered using a Tomtec cell harvester with GF/A filters (Wallac) (presoaked in 0.6% polyethylenimine) and washed three times with 1.0 mL ice-cold wash buffer (the above incubation buffer without 1,10-phenanthroline and Complete™ protease inhibitor tablet). The filters were dried in a 37° C. oven, placed in a sample bag and 5 mL Betaplatescint (Wallac) was added. Prepared filters were counted in cassettes in a Microbeta Trilux (Wallac) for 1 min.

Assay: Mps-1 Kinase Assay: For the assay 50 nL of a 100-fold concentrated solution of the test compound in DMSO was pipetted into a black low volume 384 well microtiter plate (Greiner Bio-One, Frickenhausen, Germany), 2 ul of a solution of Mps-1 in assay buffer [0.1 mM sodium- ortho-vanadate, 10 mM MgCl2, 2 mM DTT, 25 mM Hepes pH 7.7, 0.05% BSA, 0.001% Pluronic F-127] were added and the mixture was incubated for 15 min at 22° C. to allow pre-binding of the test compounds to Mps-1 before the start of the kinase reaction. Then the kinase reaction was started by the addition of 3 ul of a solution of 16.7 adenosine-tri-phosphate (ATP, 16.7 uM=> final conc. in the 5 ul assay volume is 10 uM) and peptide substrate (1.67 uM=> final conc. in the 5 ul assay volume is 1 uM) in assay buffer and the resulting mixture was incubated for a reaction time of 60 min at 22° C. The concentration of Mps-1 in the assay was adjusted to the activity of the enzyme lot and was chosen appropriate to have the assay in the linear range, typical enzyme concentrations were in the range of about 1 nM (final conc. in the 5 ul assay volume). The reaction was stopped by the addition of 3 ul of a solution of HTRF detection reagents (100 mM Hepes pH 7.4, 0.1% BSA, 40 mM EDTA, 140 nM Streptavidin-XLent [#61GSTXLB, Fa. Cis Biointernational, Marcoule, France], 1.5 nM anti-phospho(Ser/Thr)-Europium-antibody [#AD0180, PerkinElmer LAS, Rodgau-Jugesheim, Germany]. The resulting mixture was incubated 1 h at 22° C. to allow the binding of the phosphorylated peptide to the anti-phospho(Ser/Thr)-Europium-antibody. Subsequently the amount of phosphorylated substrate was evaluated by measurement of the resonance energy transfer from the Europium-labelled anti-phospho(Ser/Thr) antibody to the Streptavidin-XLent. Therefore, the fluorescence emissions at 620 nm and 665 nm after excitation at 350 nm was measured in a Viewlux TR-FRET reader (PerkinElmer LAS, Rodgau-Jugesheim, Germany).

Assay: Biochemical Assay: The FASN enzyme was isolated from SKBr3 cells. SKBr3 is a human breast cancer cell-line with high levels of FASN expression. It is estimated that FASN comprises about 25% of the cytosolic proteins in this cell line. SKBr3 cells were homogenized in a dounce homogenizer then centrifuged for 15 minutes at 4° C. to remove particulate matter. The supernatant was then analyzed for protein content, diluted to the appropriate concentration, and used to measure FASN activity. The presence of FASN was confirmed by western blot analysis. A similar method for isolation of FASN from SKBr3 cells is described in Teresa, P. et al. (Clin. Cancer Res. 2009; 15(24), 7608-7615). FASN activity of the SKBr3 cell extract was determined by measuring either NADPH oxidation or the amount of thiol-containing coenzyme A (CoA) released during the fatty acid synthase reaction. The dye CPM (7-diethylamino-3-(4'-maleimidyl-phenyl)-4-methylcoumarin) contains a thiol reactive group that increases its fluorescence emission on reaction with the sulfhydryl group of CoA.
