Assay: Biochemical Assay: The autoparsylation activity of the TNKS 1/2 or PARP1/2 enzymes was measured by the liquid chromatography-mass spectrometry (LC/MS) detection of nicotinamide as readout. Compound activity in inhibiting the TNKS and PARP autoparsylation was evaluated by IC50 measurements. In the compound screening assays, the reaction is composed of 5 μL of compound in 8-point serial dilutions with concentrations ranging from 0.0086 to 18.75 μM, 20 nM of purified enzyme, and 250 μM of β-NAD+ in the 1× Assay Buffer. After 60 min incubation at room temperature, the reactions were quenched by the addition of 10 μL of 5× quenching solution (20% formic acid and 500 nM [d]-nicotinamide in water). For the background control wells, 10 μL of the 5× quenching solution per well was added prior to the addition of β-NAD+.

UniProt: P98170
Assay: TR-FRET Assay: The peptide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA ("Peptide A") was identified as a substrate for the TR-FRET assay by screening the 6× Histidine-tagged BIR2 domain and BIR3 domain of XIAP against a set of 29 peptides synthesized based on sequences reported by Sweeny et al. (Biochemistry, 2006, 45, 14740 14748). The peptides were labeled with the fluorescent tags FITC or TAMRA and Kd values were determined by fluorescence polarization assay. The sequence AVPIAQKSEK was identified as optimal for using in an assay. The peptide sequence was derivatized with biotin to provide AVPIAQKSEK-(Îµ-biotin)-OH 1:2 TFA as the substrate for the TR-FRET assay. Ten nanomolar of 6× Histidine-tagged BIR2 domain, corresponding to amino acids 124-240 of XIAP, or BIR3 domain, corresponding to amino acids 241-356 of XIAP, was mixed with 20 nM of the peptide AVPIAQKSEK-(ε-biotin)-OH 1:2 TFA, in the presence of 50 mM Tris-Cl, pH 7.5, 100 mM NaCl, 1 mM dithiothreitol (DTT) and 0.1 mg/mL bovine serum albumin (BSA). Following a 45 min. incubation at 37° C., Europium-Streptavidin and Allophycocyanin conjugated anti-Histidine antibody were added to a final concentration of 1.5 nM and 15 nM, respectively. Time-resolved fluorescence resonance energy transfer (TR-FRET) signals were measured 1 hour later at room temperature. Test compound potency was assessed at 10 serially diluted concentrations.

Assay: Homogeneous Time Resolved Fluorescence Assay: The ability of the compounds of the present invention to inhibit the activity of four PI3K isoforms, PI3Kα, PI3Kβ, PI3Kγ, and PI3Kδ, were determined using a commercially available lipid kinase assay run in Homogeneous Time Resolved Fluorescence (HTRF) format. Assay DescriptionAssay principle: The PIP3 product is detected by displacement of biotin-PIP3 from an energy transfer complex consisting of Europium labeled anti-GST monoclonal antibody, a GST-tagged pleckstrin homology (PH) domain, biotinylated PIP3 and Streptavidin-Allophycocyanin (APC). Excitation of Europium in the complex results in an energy transfer to the APC and a fluorescent emission at 665 nm. The PIP3 product formed by PI 3-Kinase(h) activity displaces biotin-PIP3 from the complex resulting in a loss of energy transfer and thus a decrease in signal.This is a 3-step reaction: First, the kinase reaction with PIP2 substrate is carried out in the presence of ATP, and the reaction is quenched.

Assay: In Vitro Canine TRPM8 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-TM (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-TM 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. Curves were generated using the average of quadruplicate wells for each data point.

Assay: Glucokinase-Activating Assay: To test the exemplified compounds, the following assay was employed. Recombinant human liver glucokinase was expressed as a FLAG fusion protein in E. coli, and purified on ANTIFLAG M2 AFFINITY GEL (Sigma). The assay was carried out at 30° C. in a 96-well plate. In the plate was distributed 69 ul each of assay buffer (25 mM Hepes Buffer: pH=7.2, 2 mM MgCl2, 1 mM ATP, 0.5 mM TNAD, 1 mM dithiothreitol), to which was added 1 ul of a DMSO solution of the compound or DMSO as control. Then, 20 ul of pre-ice-cooled enzyme mixture (FLAG-GK, 20 U/ml G6PDH) was distributed thereto, to which was added 10 ul of 25 mM glucose as substrate to initiate the reaction (final glucose concentration=2.5 mM). After starting the reaction, the absorbance at 405 nm was measured every 30 seconds for 10 minutes to evaluate the compound based on the initial increase for 5 minutes. FLAG-GK was added so that the increase of absorbance after 5 minutes fell between 0.05 to 0.1 in the presence of 1% DMSO. The OD values of the respective compounds were measured in the respective concentrations, wherein the OD value of DMSO as control is regarded as 100%. From the OD values at the respective concentrations, Emax (%, 2.5 mM Glu) and EC50 (nM, 2.5 mM Glu) were calculated and used as indicators of the GK activation capability of the compounds.

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: DELFIA Assay: The kinase activity is measured by DELFIA assay (dissociation-enhanced lanthanide fluorescence immunoassay, Perkin Elmer). The cytoplasmic kinase domain of human IGF-1R (amino acids 964-1370) is expressed as a fusion protein with a glutathione-S-transferase tag (IGF-1R-GST) in High Five.TM. Cells (Invitrogen). Enzyme activity is measured in the presence of substances and a control substance. Poly-glutamate-tyrosine peptide (pEY, Sigma Aldrich) and biotinylated pEY (bio-pEY) are used as reaction substrates.10 uL of substance in 25% DMSO are mixed with 30 uL of IGF-1R-GST solution (67 mM HEPES pH 7.4, 15 ug/mL pEY, 1.7 ug/mL bio-pEY, 13.3 mM MgCl2, 3.3 mM dithiothreitol, 0.0033% Brij 35, 2 ng IGF-1R-GST) in 96-well plates. The reactions are started with 10 uL of a 750 uM ATP solution. After 40 min at RT the reactions are stopped with 50 .mu.L of stop solution (250 mM EDTA, 20 mM HEPES pH 7.4). 90 uL from each reaction are transferred.
