Assay: In Vitro Inhibition of Ca Flux Assay: The 5HT3 antagonist activity of the compounds of the invention was determined by measuring the ability of the compounds to inhibit the calcium flux activity of 3HT3a receptor expressed in HEK-293T cells. HEK-293T cells were transfected with the 5HT3a expression construct using Xtreme Gene 9 (Roche) in 150 mm tissue culture treated plates and incubated for 24 hours at 37 °C. Cells were then split and plated at a density of 60K cells/well in poly-lysine coated, black 96-well plates with clear bottoms (BD BioSciences) and incubated overnight at 37 °C. Growth media was removed and cells loaded with 200 uL calcium indicator dye in HBSS containing 20 mM HEPES (Calcium 5 Assay kit, Molecular Devices) and incubated at 37 °C. for 1 hour. While cells were incubating, the 10× antagonist and agonist/antagonist addition plates were made. For 10× antagonist plate: half log serial dilutions (final concentrations range from 10−7 through 10−10 with the bottom well a negative, no ligand control) were made from test compounds in DMSO at a 1000× concentration and then diluted to 10× in HBSS/20 mM HEPES. For addition plate: 5HT was diluted to 100× in HBSS/20 mM HEPES (final concentration in the assay−216 nM) and 15 uL was added to each well of the addition plate, 15 uL of 10× compound was also added to the addition plate, and finally 120 uL of HBSS/20 mM HEPES (for a total of 150 uL). Cells were then removed from the incubator and equilibrated to room temperature for 10 minutes, then 22.5 uL of 10× test compounds were added in triplicate to the plates and incubated at room temperature for 10 minutes (Tropisetron was used as a positive control in every assay). Test plate and addition plate were loaded into the FlexStation III (Molecular Devices), and using the fluidics, 22.5 uL compound additions were made (at t=~17 seconds), and fluorescence was measured for 90 seconds, reading every 2.2 seconds.

Assay: HTRF FRET Assay: A homogeneous time-resolved FRET assay can be used to determine IC50 values for inhibitors of the soluble human BACE1 catalytic domain. This assay monitors the increase of 620 nm fluorescence that resulted from BACE1 cleavage of an APPswedish APPswe mutant peptide FRET substrate (QSY7-EISEVNLDAEFC-Europium-amide). This substrate contains an N-terminal QSY7 moiety that serves as a quencher of the C-terminal Europium fluorophore (620 nm Em). In the absence of enzyme activity, 620 nm fluorescence is low in the assay and increased linearly over 3 hours in the presence of uninhibited BACE1 enzyme. Inhibition of BACE1 cleavage of the QSY7-APPswe-Eu substrate by inhibitors is manifested as a suppression of 620 nm fluorescence.Varying concentrations of inhibitors at 3x the final desired concentration in a volume of 10 ul are preincubated with purified human BACE1 catalytic domain (3 nM in 10 ul) for 30 minutes at 30° C. in reaction buffer containing 20 mM Na-Acetate pH 5.0, 10% glycerol, 0.1% Brij-35 and 7.5% DSMO. Reactions are initiated by addition of 10 ul of 600 nM QSY7-APPswe-Eu substrate (200 nM final) to give a final reaction volume of 30 ul in a 384 well Nunc HTRF plate. The reactions are incubated at 30° C. for 1.5 hours. The 620 nm fluorescence is then read on a Rubystar HTRF plate reader (BMG Labtechnologies) using a 50 millisecond delay followed by a 400 millisecond acquisition time window. Inhibitor IC50 values are derived from non-linear regression analysis of concentration response curves. Ki values are then calculated from IC50 values using the Cheng-Prusoff equation using a previously determined um value of 8 uM for the QSY7-APPswe-Eu substrate at BACE1.

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: G402-Based Assay: Herein we identified the use of the G-402 cell line as a host cell to ectopically express (transiently or stably) enzymes of the CYP11 family. Specifically we developed stable G-402 cells expressing ectopically human CYP11B1, human CYP11B2, human CYP11A1, cynmolgus CYP11B1 or cynomolgus CYP11B2 enzyme activity. Importantly the identified cell line G-402 expresses co-factors (adrenodoxin and adrenodoxin reductase) important for the activity of the CYP11 family and no relevant enzyme activity of the CYP11 family (in comparison to H295R cells) was detected in these cells. Therefore the G-402 cell line is uniquely suited as a host cell for the ectopic expression of enzymes from the CYP11 family.Cellular enzyme assays were performed in DMEM/F12 medium containing 2.5% charcoal treated FCS and appropriate concentration of substrate (0.3-10 uM 11-Deoxycorticosterone, 11-Deoxycortisol or Corticosterone). For assaying enzymatic activity, cells were plated onto 96 well plates and incubated for 16 h. An aliquot of the supernatant is then transferred and analyzed for the concentration of the expected product (Aldosterone for CYP11B2; Cortisol for CYP11B1). The concentrations of these steroids can be determined using HTRF assays from CisBio analyzing either Aldosterone or Cortisol.

(3-NADH conversion to NAD+ is monitored by the decrease in absorbance at 340 nm (e=6.22 cm-1 mM-1) using a Molecular Devices SPECTRA max PLUS spectrophotometer.A typical assay was carried out on a 96-well, clear microtiter plate in a Molecular Devices spectrophotometer for 20 minutes at 30 C. in 0.1 mL of assay buffer containing 50 mM HEPES, pH 7.4, 5 nM PKC, 23 units of pyruvate kinase, 33 units of lactate dehydrogenase, 0.15 mM peptide, 0.1 mM ATP, 1 mM DTT, 4 mM PEP, 8 mM MgCl2, 0.3 mM NADH, 60 mM CaCl2, 10 mg/mL PS, 50 ng/mL PMA, 7.5% DMSO and from about 10,000 nM to 0.169 nM compound inhibitor.

Assay: Active ERK2 (aERK) Assay: Activated ERK2 activity was also determined in the IMAP assay format using the procedure outlined above. 1 μl of 25× compound was added to 14 μl of kinase buffer containing 0.25 ng fully phosphorylated, active Mouse ERK2 protein. Following a 30 minute incubation, the reactions were initiated by addition of 10 μl of kinase buffer containing 1 μM ERK2 IMAP substrate peptide (0.9 μM unlabeled IPTTPITTTYFFFK-CONH2 and 100 nM IPTTPITTTYFFFK(5-carboxyfluorescein)-CONH2) and 30 μM ATP. Reactions proceeded for 30 minutes before termination by addition of 60 μl IMAP detection beads in binding buffer. Plates were read as above after 30 minute binding equilibration. Active compounds were reconfirmed in an independent assay.

Assay: In Vitro Assay: FVIIa-Xase Ki (37° C.): S2765 (0.5 mM), PCPS (25 μM), calcium chloride (5 mM), full-length human TF (3 nM), human FVIIa (5 pM), and FVIIa inhibitor were incubated for 15 min at 37° C. Reactions were initiated by the addition of human FX (range of concentrations). Preliminary experiments revealed that the plasma purified FX contains a residual amount of human FVIIa which could not be removed by affinity chromatography. The residual FVIIa is sufficient, when combined with PCPS, calcium and TF to catalyze the conversion of FX to Xa, and was increased by the addition of 5 pM human FVIIa. FXa in turn hydrolyses S2765, which was monitored for 60 min at 405 nm.
