Assay: In Vitro DGAT2 Assay: For determination of IC50 values, the reactions were carried out in 384-well white Polyplates (Perkin Elmer) in a total volume of 20 uL. To 1 uL of compounds dissolved in 100% DMSO and spotted at the bottom of each well, 5 uL of 0.04% bovine serum albumin (BSA) (fatty acid free, Sigma Aldrich) was added and the mixture was incubated at room temperature for 20 minutes. To this mixture, 10 uL of hDGAT2 membrane fraction (0.01 mg/mL) diluted in 100 mM Hepes-NaOH, pH 7.4, 20 mM MgCl2 containing 200 nM methyl arachidonyl fluorophosphonate (Cayman Chemical; dried from ethyl acetate stock solution under argon gas and dissolved in DMSO as 5 mM stock) was added. After this mixture was preincubated at room temperature for 2 hours, DGAT2 reactions were initiated by the addition of 4 uL of substrates containing 30 uM [1-14C]decanoyl-CoA (custom-synthesized by Perkin Elmer, 50 mCi/mmol) and 125 uM 1,2-didecanoyl-sn-glycerol (Avanti Polar Lipids) dissolved in 12.5% acetone. The reaction mixtures were incubated at room temperature for 40 min and the reactions were stopped by addition of 5 uL of 1% H3PO4. After the addition of 45 uL MicroScint-E (Perkin-Elmer), plates were sealed with Top Seal-A covers (Perkin-Elmer) and phase partitioning of substrates and products was achieved using a HT-91100 microplate orbital shaker (Big Bear Automation, Santa Clara, Calif.). Plates were centrifuged at 2,000×g for 1 min in an Allegra 6R Centrifuge (Beckman Coulter) and then were sealed again with fresh covers before reading in a 1450 Microbeta Wallac Trilux Scintillation Counter (Perkin Elmer). DGAT2 activity was measured by quantifying the generated product [14C]tridecanoylglycerol in the upper organic phase.

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.

UniProt: P11309
Assay: Enzyme Assay: 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 96-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 10-point dosing curve having a high dose of 1 uM.

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: Lantha Screen Technology Assay: LRRK2 kinase activity was measured using Lantha Screen technology from Invitrogen. GST-tagged truncated LRRK2 from Invitrogen (Cat # PV4874) was incubated with a fluorescein-labeled peptide substrate based upon ezrin/radixin/moesin (ERM), also known as LRRKtide (Invitrogen cat #PR8976A), in the presence of a dose response of compound. Upon completion, the assay was stopped and detected with a terbium labeled anti-phospho-ERM antibody (Invitrogen, cat #PR8975A). The assay was carried out under the following protocol: 3 uL of a working solution of substrate (233 nM LRRKtide, 117 uM ATP) prepared in assay buffer (50 mM HEEPES, pH 7.5, 3 mM MgCl2, with 2 mM DTT and 0.01% Brij35 added fresh) was added to a low volume Greiner 384-well plate. The compound dose response was prepared by diluting compound to a top concentration of 3.16 mM in 100% DMSO and serial diluted by half-log in DMSO 11 times. Aliquots (3.5 uL) of the 100% DMSO dose response were mixed with 46.5 uL water.

Assay: FRET Assay: Methods: An HDM2 FRET assay was developed to assess the compounds' inhibitory activity towards binding of p53 protein. A truncated version of HDM2 with residues 17 to 125 (containing p53 binding surface, Science (1994) 265, 346-355), with N-terminal His and Thioredoxin tag was generated in pET32a expression vector and expressed in E. coli strain BL21(DE3)Rosetta. Protein was purified using Ni-affinity chromatography, followed by size exclusion chromatography using Superdex 75 26/60 column. To assess inhibition of p53 binding to HDM2, a FITC labeled 8-mer peptide (SEQ ID NO:1: Ac-Phe-Arg-Dpr-Ac6c-(6-Br)Trp-Glu-Glu-Leu-NH2; Anal Biochem. 2004 Aug. 1; 331(1):138-46) with strong affinity towards the p53 binding pocket of HDM2 was used. The HDM2 assay buffer contained 1x Phosphate Buffered Saline (Invitrogen, Cat#14190), 0.01% BSA (Jackson ImmunoResearch, Cat#001-000-162), 0.01% Tween-20. In the 1x assay buffer recombinant HDM2 protein, peptide and Lumi-4-Tb Cryptate-conjugate mouse.
