Assay: MGAT LCMS Assay: The MGAT enzyme reactions were performed in CORNING Falcon 96-well Polypropylene plates, in a total volume of 60 uL of 50 mM Potassium Phosphate buffer pH 7.4, containing a final concentration of 100 uM 2-oleoylglycerol, 15 uM oleoyl-Coenzyme A and 0.0013 ug/uL Human or Mouse MGAT-2 or 0.0026 ug/uL Rat recombinant MGAT-2 membranes expressed in Sf9 cells. Assay plates were run through a fully automated robotics system and shaken for 5 seconds every minute for a total 10 minutes. The reactions were then quenched with 120 uL of ice cold methanol containing 1 ug/mL 1,2-distearoyl-rac-glycerol as the internal standard. Plates were shaken for 2 minutes and spun down to remove protein precipitation. After the spin, samples were transferred to LC/MS compatible PCR plates. For LC/MS analysis, a ThermoFisher Surveyor pump, utilizing a Waters Symmetry C8, 50x2.1 mm column, was used for the chromatography of enzyme products.

Assay: ThermoFluor® Assay: Bar-coded assay plates are robotically loaded onto a thermostatically controlled PCR-type thermal block and then heated at a typical ramp-rate of 1 °C./min for all experiments. Fluorescence was measured by continuous illumination with UV light (Hamamatsu LC6) supplied via fiber optic and filtered through a band-pass filter (380-400 nm; >6 OD cutoff). Fluorescence emission of the entire 384-well plate was detected by measuring light intensity using a CCD camera (Sensys, Roper Scientific) filtered to detect 500±25 nm, resulting in simultaneous and independent readings of all 384 wells. Images were collected at each temperature, and the sum of the pixel intensity in a given area of the assay plate was recorded versus temperature. Reference wells contained RORγt without compounds, and the assay conditions were as follows: 0.065 mg/mL RORγt, 60 μM 1,8-ANS, 100 mM Hepes, pH 7.0, 10 mM NaCl, 2.5 mM GSH, 0.002% Tween-20. Project compounds were arranged in a pre-dosed mother plate (Greiner Bio-one) wherein compounds are serially diluted in 100% DMSO by 1:2 from a high concentration of 10 mM over 12 columns within a series (column 12 is a reference well containing DMSO, no compound). The compounds were robotically dispensed directly into assay plates (1×=46 nL) using a Hummingbird capillary liquid handling instrument (Digilab). Following compound dispense, protein and dye in buffer was added to achieve the final assay volume of 3 μL, followed by 1 μL of silicone oil.

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: Kinase Assay (New): Compound potency against activated ERK2 is determined using a kinase assay that measures ERK2-catalyzed phosphorylation of biotinylated ERKtide peptide substrate ([Biotin]-AHA-K-R-E-L-V-E-P-L-T-P-S-G-E-A-P-N-Q-A-L-L-R-[NH2], the peptide sequence derived from EGF receptor: SEQ ID NO:1). The assay is carried out in 50 mM HEPES [pH 7.5], 5 mM MgCl2, 1 mM DTT, 0.01% Tween-20, 0.05% BSA using 0.25 nM ERK2, 200 nM ERKtide peptide and 35 uM ATP (all concentrations are final in the reaction) in a total volume of 10.25 uL. A 16-point, half-log dilution series of compounds at 41x final concentration is used for generating IC50 curves. Compound dilution series are prepared in 100% DMSO. ERK2 is preincubated with compounds for 30 minutes at ambient temperature. Reaction is initiated by addition of a substrate cocktail of ERKtide peptide and ATP and is allowed to proceed for 2-3 hours at ambient temperature. Reaction is terminated by addition of 10 uL of a 2x stop buffer consisting of 100 mM Tris-Cl [pH 7.5], 25 mM EDTA, 0.01% Tween 20, 10 ug/mL of AlphaScreen Protein A Acceptor Beads, 10 ug/mL of Streptavidin Donor Beads (PerkinElmer, Waltham, Mass.), and 1.4 ug/mL phospho-EGF Receptor (Thr669) antibody (Cat #3056, Cell Signaling Technology, Danvers, Mass.).

[Materials]: Optiplate-384 well plate (PerKinElmer), kinase buffer (50 mM Hepes pH7.5, 0.25 mM EGTA, 2 mM DTT, 0.01% Tween 20, 10 mM Mg2+, 0.5 mM Mn2+), KDR kinase (790-1356 AA, Crown Bioscience), KDR kinase substrate (PerKinElmer catalogue # TRF0127-M), Lance@Eu-W1024-anti-phosphotyrosine (PT66) (PerKinElmer, catalogue #AD0068), ATP (Invitrogen), DMSO (Sigma, catalogue #34869), purified water (Millipore, type: Milli-Q). [Study conditions]: Mix KDR (final concentration: 20 nM) and compound (final DMSO: 0.5%), pre-incubate for 20 min at 30° C.; then add ATP (final concentration: 90 μM) and the substrate (final concentration 50 μM). React for 2 hrs at 30° C. After the reaction, add antibody and reaction for 60 min at 30° C. Read the plate (615 nm, 665 nm), calculate the ratio of the value at 665 nm vs 615 nm and analyze the data.

Target: Plasma kallikrein (SINGLE PROTEIN), Homo sapiens
UniProt: P03952
Assay: In-vitro Plasma Kallikrein Inhibition: Enzymatic reactions were conducted in â¿¿assay bufferâ¿¿, comprising 50 mM Hepes/NaOH at pH 7.8, 150 mM NaCl, 1 mM EDTA and 0.05% (w/v) CHAPS. For the determination of IC50 values, the assays were performed at room temperature in 384-well plates with a total assay volume of 25.25 ul per well. The test compound was dissolved in 90% (v/v) DMSO/water. For the assays, 250 nL of the 90% (v/v) DMSO/water solution or compound solution were added per well, followed by the addition of 12.5 ul protease solution (protease in assay buffer). The final assay concentration of the human plasma kallikrein was nominally 25 pM, the 11 compound concentrations in the dilution series were in the range form 1 nM to 100 uM. After 1 hour of pre-incubation at room temperature, the reactions were started by the addition of 12.5 ul substrate solution (in assay buffer, final assay concentration was 0.5 uM). After the addition of the substrate solution, the final DMSO concentration in the assay was 0.9% (v/v).

Assay: Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay: The inhibition constant (Ki) is the dissociation constant of an enzyme-inhibitor complex or a protein/small molecule complex, wherein the small molecule is inhibiting binding of one protein to another protein or peptide. Where the Ki for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-XL) is greater than the limits of detection of the assay used. Where the binding selectivity ratio for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the selectivity of a particular compound for Bcl-2 over Bcl-XL is at least as great as the number indicated. Where the Ki for a compound is represented as < (less than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-2) is lower than the limit of detection of the assay used. Inhibition constants were determined using Wang's equation (Wang Z-X).
