InChIKey: XCIUIPKNQZQPPE-UHFFFAOYSA-N
Target: Galactokinase (SINGLE PROTEIN), Homo sapiens
UniProt: P51570
Assay: qHTS Assay: Assay details and protocol: The primary assay monitored ATP depletion using Promega's KinaseGlo technology, where ATP levels are measured through luminescence generated from firefly luciferase, a bioluminescent ATP-dependent enzymes. ATP was held at 35 μM, near its reported KM value, and the KM for galactose was determined under the 1536-well assay conditions to be 50-100M (FIG. 1A). As well, the IC50 for a commercially available CD45 inhibitor (N-(9,10-dioxo-9,10-dihydrophenanthren-2-yl)pivalamide) was confirmed (previously found to inhibit GALK (FIG. 1B)). This was used as the positive control for the assay. The assay used 5 nM GALK and a 1 hr incubation time, which gave sufficient signal:background and stability for the HTS.

UniProt: Q1A7N1
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.

The plates are left at room temperature for a further 2 hours before addition of 10 μl of the DiscoveRx PathHunter detection reagent (made up by adding 1 part Galacton Star, 5 parts Emerald II and 19 parts Cell Assay Buffer as per the manufacturer's instructions). After reagent addition, plates are covered and incubated at room temperature for 60 minutes. Luminescence signal is read using an Envision.

Target: Apoptosis regulator Bcl-2 (SINGLE PROTEIN), Homo sapiens
UniProt: P10415
Assay: Fluorescence Polarization Assay (FPA): The assays were performed in black flat-bottom 384-well plates. The final assay volume was 50 μl prepared from additions of Gst-Bcl-2 (Bcl-2: GENBANK® Accession No. P10415), fluoresceinated 18-mer BIM peptide (NH2-YYANFEDGIRRLEQAIWI-[FAM]) (SEQ ID NO: 1), and test compounds in assay buffer consisting of 20 mM Sodium Phosphate, 1 mM EDTA, 50 mM NaCl, and 0.05% Pluronic Acid. The reaction was incubated at room temperature for 60 minutes and fluorescence polarization of the reaction was detected on the LJL Plate Reader. Inhibition data were calculated from mP values generated by the no protein control reactions for 100% inhibition and vehicle-only reactions for 0% inhibition. The final concentrations of reagents in the assay were 4.9 nM BCL-2, 5 nM fluoresceinated 18-mer BIM peptide and 1% DMSO.

Target: Serine/threonine-protein kinase pim-1 (SINGLE PROTEIN), Homo sapiens
UniProt: P11309
Assay: Homogeneous Time Resolved Fluorescence Assay (HTRF): 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 μM. A reference compound was included on each assay plate in order to validate that plate; on one plate of every assay run, two additional reference compounds were included. The final buffer conditions were as follows: 60 mM Hepes, pH 7.0, 0.05% BSA, 2 mM DTT. Incubations were carried out at RT (22° C.) for 2 h for Pim-1, 1 hour and 30 min for Pim-3, and 45 min for Pim-2. The reaction was stopped by the addition of 3 mM EDTA, and fluorescence was measured by an HTRF® Rubystar microplate reader.

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).
