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.

Target: Fatty acid synthase (SINGLE PROTEIN), Homo sapiens
UniProt: P49327
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: 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.

UniProt: Q06187
Assay: Recombinant Human BTK Inhibition Assay: The inhibition assays were performed using the generic tyrosine kinase assay kit from C is Bio (HTRF KinEASE-TK #62TK0PEB). The assay is based on the principle of fluorescence resonance energy transfer (FRET) between the Europium Cryptate labeled anti-phosphotyrosine antibody and streptavidin labeled fluorophore, XL-665. In an uninhibited kinase reaction the biotinylated peptide substrate (Tk-Biotin) gets phosphorylated at an intermediate tyrosine site which is captured by anti-phosphotyrosine antibody which eventually acts as a FRET donor. The streptavidin labeled XL-665 binds strongly to the Tk-Biotin substrate and act as a FRET acceptor. The resultant FRET signal is measured at 665 nm. A ratio of this specific fluorescence (665 nm) to the background fluorescence (620 nm), conferred by the free antibody, is directly proportional to the kinase activity. Inhibition of the kinase activity by a pharmacological intervention such as a Btk inhibitor of the present disclosure will result into decreased FRET signal.

Assay: HTRF FRET Assay: 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 3× the final desired concentration in a volume of 10 ul are preincubated with purified human BACE1 catalytic domain (3 nM in 10 μl) 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 μl of 600 nM QSY7-APPswe-Eu substrate (200 nM final) to give a final reaction volume of 30 μl 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.

Assay: Radioligand Displacement Assay: Binding assay was performed in a final assay volume of 250 ul. First, 25 ul of test compound, previously diluted in Binding-Buffer (Binding-Buffer: 50 mM Tris-Base, 100 mM NaCl, 1 mM EDTA, 0.1% BSA (protease free), 0.01% NaN3, 10 mM MnCl2, pH 7.0) was placed into each well. After addition of 75 ul Binding-Buffer, 50 ul of the radioligand 3H-PGD2 (at 2.5 nM (220.000 dpm/well) from ANAWA ART0662) was added to each well. Binding assay was started by addition of 100 ul CRTH2 membrane fragments, reaching a final concentration of 20 ug/well. For non-specific binding, PGD2 was added to the reaction mixture to 10 mM final concentration. This assay mix was incubated for 90 minutes at room temperature and then filtered through a GF/C filter 96-well plate which was pre-soaked for 3 hours in 0.5% polyethyleneimine (PEI). The filter-wells were washed three times with ice cold Binding-Buffer. Then, 40 ul of Microscint-40 (Packard) was added to each well and the retained radioactivity quantified in a Topcount (Packard).
