Assay: Radioligand Binding Assay: Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat #SH30022), 10% FBS, 1x Pen/Strep, 1x sodium pyruvate, 10 mM HEPES, 600 ug/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1x Pen/Strep, 600 ug/mL G418 media, respectively on 150 cm^2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1x with Calcium and Magnesium, Cat #SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2KxG, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at -80\°C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 uM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 uM almorexant. The total volume of each reaction is 200 uL (20 uL of diluted compounds, 80 uL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 uL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).

Assay: AlphaLISA Assay: An in-vitro AlphaLISA assay (Perkin Elmer) was developed in order to quantitate the level of PCSK9 secreted into the cell culture media following compound treatment. To detect and measure PCSK9 protein an in-house generated anti-PCSK9 antibody was coupled to AlphaLISA acceptor beads by an external vendor (PerkinElmer) and a second internally developed anti-PCSK9 antibody with an epiptope distinct from that of the acceptor beads was biotinylated in house. Streptavidin coated-donor beads (Perkin Elmer) are also included in the assay mixture which then binds the biotinylated anti-PCSK9 antibody and in the presence of PCSK9 this donor complex and acceptor beads are brought into close proximity. Upon excitation of the donor beads at 680 nm singlet oxygen molecules are released that trigger an energy transfer cascade within the acceptor beads resolving as a single peak of light emitted at 615 nm. The ability of compound to modulate PCSK9 protein levels in conditioned media by AlphaLISA was assessed in the human hepatocellular carcinoma cell line Huh7, stably over-expressing human PCSK9.

Assay: Beta1-AR Binding Assay: Beta1-AR binding was done on rat cortical membrane following a previously described procedure (Beer et al., Biochem. Pharmacol. 37: 1145-1151, 1988). In brief, male Sprague-Dawley rats weighing 250-350 g were decapitated and their brains quickly removed. The cerebral cortices were dissected on ice, weighed and promptly transferred to a 50 ml test tube containing approximately 30 ml of 50 mM Tris-HCl, pH 7.8 (at room temperature). The tissues were homogenized with a polytron and centrifuged at 20,000xg for 12 min at 4° C. The pellet was washed again in the same manner and resuspended at a concentration of 20 mg (original wet wt) per 1 ml in the assay buffer (20 mM Tris-HCl, 10 mM MgCl2, 1 mM EDTA, 0.1 mM ascorbic acid at pH 7.8). To block the beta2 sites present in the cortical membrane preparation, 30 nM ICI 118-551 was also added to the assay buffer. To wells containing 100 ul of the test drug and 100 ul of [3H]CGP-12177 (1.4 nM final concentration), 0.8 ml of tissue homogenate was added. After 2 hours at 25° C., the incubation was terminated by rapid filtration. Nonspecific binding was determined by 10 uM propranolol.

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: FLIPR Assay: The bioactivity of compounds is tested in a fluorometric imaging plate reader (FLIPR: Molecular Devices) using engineered CHO-K1 cells expressing the human CXCR3A coupled to a G protein (Galpha(16)). Cells are plated the day prior to bioassay in F12 medium supplemented with 10% FBS and G418 and hygromycin antibiotics to maintain recombinant selection. At the day of bioassay, cells are washed and dye loaded for one hour with Fluo-4-AM (Invitrogen) in Hanks Balanced Salt Solution (Invitrogen), buffered with 20 mM Hepes at pH 7.4 and sodium bicarbonate (0.015%), containing 5 mM probenecid. This buffer, but lacking the dye and containing probenecid at a concentration of 2.5 nM, is also is used for washing steps (wash buffer); or lacking both dye and probenecid but supplemented with 0.1% BSA for compound dilution steps (dilution buffer). Cells are washed free of excess dye and 60 microliter of wash buffer is added. Stock solutions of test compounds are made up at a concentration of 10 mM in DMSO, and serially diluted in dilution buffer to concentrations required for inhibition dose response curves. After a 10 minute incubation period at 37° C., 10 microliters of each compound dilution are transferred from a compound plate to the plate containing the recombinant cells in the FLIPR instrument according to the manufacturer's instructions. Following basal readings, 10 microliter CXCL10 agonist at a concentration of 20 nM (from Peprotech) is added, again using the FLIPR instrument. Changes in fluorescence are monitored before and after addition of the test compounds.

Target: Estrogen receptor (SINGLE PROTEIN), Homo sapiens
UniProt: P03372
Assay: Luciferase Assay: Estrogen receptor-negative CV-1 kidney cells are maintained in Dulbecco's modified Eagle's medium with 4.5 g/L glucose supplemented with 10% fetal bovine serum and 100 units/ml penicillin-streptomycin at 37° C. in a humidified 5% CO2 atmosphere. The cells are then plated in 6-well dishes at a density of 2×10^5 cells per well in phenol-red free Dulbecco's modified Eagle's medium containing 10% charcoal-dextran-stripped fetal bovine serum. CV-1 cells are transfected using LipofectAMINE reagent according to the manufacturer's protocol. Transfections containing 1.5 μg of reporter plasmid (containing ERE-tk-luciferase containing a single ERE cloned upstream of the thymidine kinase promoter and luciferase gene) and 0.5 μg of either ERα or ERβ expression vector (containing CMV-ERα or CMV-ERβ full length coding sequence respectively). The next day, cells receive no treatment (controls) or are treated with estradiol alone (1 nM) or estradiol plus a compound of the invention (at varying concentrations). After 16-24 hours, cells are harvested and assayed for luciferase activity. At the outset, cell monolayers are washed twice with ice-cold phosphate-buffered saline and incubated for 15 minutes in 250 μl of 1× cell culture lysis reagent (Promega, Madison, Wis.). Cell extracts are transferred to a fresh tube and assayed using the luciferase assay system (Promega). For each assay, 10 μl of extract is diluted with 90 μl of 1× cell culture lysis reagent. Luminescence is read using an AutoLumat LB953 luminometer.

Assay: Biochemical Inhibition Assay: The NAMPT enzymatic reactions were carried out in Buffer A (50 mM Hepes pH 7.5, 50 mM NaCl, 5 mM MgCl2, and 1 mM THP) in 96-well V-bottom plates. The compound titrations were performed in a separate dilution plate by serially diluting the compounds in DMSO to make a 100x stock. Buffer A (89 uL) containing 33 nM of NAMPT protein was added to 1 uL of 100x compound plate containing controls (e.g. DMSO or blank). The compound and enzyme mix was incubated for 15 minutes at room temperature, then 10 uL of 10x substrate and co-factors in Buffer A were added to the test well to make a final concentration of 1 uM NAM, 100 uM 5-Phospho-D-ribose 1-diphosphate (PRPP), and 2.5 mM Adenosine 5'-triphosphate (ATP). The reaction was allowed to proceed for 30 minutes at room temperature, then was quenched with the addition of 11 uL of a solution of formic acid and L-Cystathionine to make a final concentration of 1% formic acid and 10 uM L-Cystathionine.
