Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
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. A reference compound was included on each assay plate in order to validate that plate; on

Target: Tyrosine-protein kinase BTK (SINGLE PROTEIN), Homo sapiens
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: Scintillation Proximity Assay (SPA): First, low density lipoprotein (LDL) (Meridian) was biotinylated by incubating LDL with biotin for 1 hour on ice, after which it was dialyzed to remove free biotin. Then compounds at varying concentrations were incubated with 15 nM CETP (reagent production group, In Vitro Pharmacology, MRL Rahway) and 50 ug/ml of the biotinylated LDL in 50 mM HEPES, 150 mM NaCl, pH 7.4, for 1 hour at 37° C. The reaction was started by adding 3H-cholesterol ester high density lipoprotein (HDL) (American Radiochemicals Corp) at a concentration of 0.6 nM. The reaction proceeded for 2 hours at 37° C., after which time it was quenched by the addition of 12% acetic acid. PVT streptavadin-coated scintillation proximity beads, which had been brought to room temperature, were then added at a concentration of 4 mg/ml. The assay was then mixed and counted after one half hour in a Microbeta plate reader.

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: 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.
