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.

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]. Final concentrations either Pim-1 enzyme [5 pM], or Pim-2 enzyme [0.5 pM], DMSO [1%], BLC BAD (S112) [0.5 μM], ATP [1.5 μM], streptavidin:Allophycocyanin [0.002 mg/mL] and biotinylated-BAD (S112) mAb [100 pM]. Initial incubations were carried out at RT (22° C.) for 30 min for both Pim-1 and for Pim-2. Pim enzyme is added to compound in buffer, and plates are incubated of 30 min. Biotinylated BAD and ATP are added and plates are incubated for 1 h. A mixture of labeled p-BAD (S112) mAb and quench/detection buffer are added and incubated for 2 h. Fluorescence was measured by an HTRF® Envision microplate reader.

Assay: In Vitro ATP-33P Casein Assay: "U"-bottomed Falcon plates are prepared by placing 5 uL of solutions of the compounds according to the invention at concentrations of 10, 1, 0.1, 0.01 or 0.001 uM in different wells. The solutions of the compounds according to the invention at these various concentrations are prepared by diluting in a test buffer (Tris 50 mM pH 7.5, MgCl2 10 M, DTT 2 mM and EGTA 1 mM) a stock solution in DMSO at a concentration of 10 mM. Next, 5 uL of dephosphorylated casein are added to a final concentration of 0.2 ug/uL, 20 uL of CK1 epsilon to a final concentration of 3 ng/uL, and 20 uL of ATP-33P to a final concentration of 0.02 uCi/uL mixed with cold ATP (10 uM final approximately 2x106 CPM per well). The final total test volume per well is equal to 50 uL. The "U"-bottomed Falcon test plate mentioned above is vortexed, and then incubated at room temperature for 2 hours. After 2 hours the reaction is stopped by adding an ice-cold solution of 65 uL of cold ATP (2 mM) prepared in test buffer. 100 uL of the reaction mixture are then transferred from the "U"-bottomed Falcon plate into Millipore MAPH filter plates, preimpregnated with 25 uL of ice-cold 100% TCA. The Millipore MAPH filter plates are agitated gently and are left to stand at room temperature for at least 30 minutes to precipitate the proteins. After 30 minutes, the filter plates are sequentially washed and filtered with 2x150 uL of 20% TCA, 2x150 uL of 10% TCA and 2x150 uL of 5% TCA (6 washes in total per plate/900 uL per well). The plates are left to dry overnight at room temperature. Next, 40 uL of Microscint-20 Packard scintillation liquid are added per well and the plates are closed in a leaktight manner. The radiation emitted by each well is then measured for 2 minutes in a TopCount NXT Packard scintillation counter, in which the values of CPM/well are measured.

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. Plates were shaken and centrifuged and then incubated 60 minutes at ambient temperature and then read on a Perkin Elmer Envision (λex=337 nm, λem=665 and 615 nm, TRF delay time=20 μs). HTRF signal=10,000*665 nm reading/615 nm reading.

Assay: Glucokinase-Activating Assay: To test the exemplified compounds, the following assay was employed. Recombinant human liver glucokinase was expressed as a FLAG fusion protein in E. coli, and purified on ANTIFLAG M2 AFFINITY GEL (Sigma). The assay was carried out at 30° C. in a 96-well plate. In the plate was distributed 69 ul each of assay buffer (25 mM Hepes Buffer: pH=7.2, 2 mM MgCl2, 1 mM ATP, 0.5 mM TNAD, 1 mM dithiothreitol), to which was added 1 ul of a DMSO solution of the compound or DMSO as control. Then, 20 ul of pre-ice-cooled enzyme mixture (FLAG-GK, 20 U/ml G6PDH) was distributed thereto, to which was added 10 ul of 25 mM glucose as substrate to initiate the reaction (final glucose concentration=2.5 mM). After starting the reaction, the absorbance at 405 nm was measured every 30 seconds for 10 minutes to evaluate the compound based on the initial increase for 5 minutes. FLAG-GK was added so that the increase of absorbance after 5 minutes fell between 0.05 to 0.1 in the presence of 1% DMSO. The OD values of the respective compounds were measured in the respective concentrations, wherein the OD value of DMSO as control is regarded as 100%. From the OD values at the respective concentrations, Emax (%, 2.5 mM Glu) and EC50 (nM, 2.5 mM Glu) were calculated and used as indicators of the GK activation capability of the compounds. According to the above assay, the GK activation capability of the exemplified compounds of the present invention was determined. The following table shows the results. Where different enantiomers of the same compound were tested, two numbers are provided. Where 3 numbers are provided, for example, Ex. #30, data for the racemic form is also shown.

Assay: Two-Hybrid Assay: Detection of MEF2D and HDAC4 interactions. In this mammalian two-hybrid assay, HDAC4 and MEF2D proteins were used as representative members of their respective protein families because the protein-protein interactions involved in the recruitment of class IIa HDACs by MEF2 were highly conserved. Two separate DNA constructs were made with MEF2D fused with the GAL4 DNA binding domain (GAL4-MEF2D) and with the MEF2-binding motif of HDAC4 (AA 155-220) fused with the viral transactivator VP-16 (HDAC4-VP16) (FIG. 1). Human epithelial carcinoma cells (HeLa) were co-transfected with the two DNA constructs (GAL4-MEF2D and HDAC4-VP16) and a reporter plasmid (Gal4Luc). The DNA constructs resulted in expression of the GAL4-MEF2D and HDAC4-VP16 fusion proteins within the cell. MEF2D and HDAC4 protein interactions were detected as a result of the GAL4-MEF2D and HDAC4-VP16 protein complex binding a DNA promoter on the reporter plasmid (Gal4Luc) and driving cellular expression of a luciferase gene.

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.

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: Inhibition Assay: mPGES-1 microsome fractions were prepared from CHO-K1 cells transiently transfected with plasmid encoding the human mPGES-1cDNA. Microsomes were diluted with potassium phosphate buffer containing reduced glutathione (pH7.4), and DMSO containing test compound or DMSO alone was added (such that DMSO final concentration would be 1% in each) and incubated at 4° C. for 20 minutes. Then, the enzymatic reactions were initiated by the addition of PGH2 substrate (final concentration 1 μM) and incubated at 4° C. for 60 seconds. The reaction was terminated by the addition of a citrate solution (final citrate concentration 50 mM) containing ferric chloride (final concentration 1 mg/mL). PGE2 production in the enzyme reaction aliquot was measured using HTRF kit (Cisbio International, catalogue #62P2APEC).

Assay: Inhibition Assay: Recombinant human cathepsin A (residues 29-480, with a C-terminal 10-His tag; R&D Systems, #1049-SE) was proteolytically activated with recombinant human cathepsin L (R&D Systems, #952-CY). Briefly, cathepsin A was incubated at 10 ug/ml with cathepsin L at 1 ug/ml in activation buffer (25 mM 2-(morpholin-4-yl)-ethanesulfonic acid (MES), pH 6.0, containing 5 mM dithiothreitol (DTT)) for 15 min at 37° C. Cathepsin L activity was then stopped by the addition of the cysteine protease inhibitor E-64 (N-(trans-epoxysuccinyl)-L-leucine-4-guanidinobutylamide; Sigma-Aldrich, # E3132; dissolved in activation buffer/DMSO) to a final concentration of 10 uM.The activated cathepsin A was diluted in assay buffer (25 mM MES, pH 5.5, containing 5 mM DTT) and mixed with the test compound (dissolved in assay buffer containing (v/v) 3% DMSO) or, in the control experiments, with the vehicle in a multiple assay plate. After incubation for 15 min at room temperature.
