UniProt: Q15858
Assay: FRET-Based Membrane Potential Assay: Two days prior to the experiment, frozen HEK293 cells stably expressing recombinant human Nav1.7 were quickly thawed and plated at 25,000 cells/well in growth medium [DMEM (Invitrogen #11965) with 10% HI FBS (Invitrogen #10082), 2 mM glutamine, 100 units/mL penicillin, 0.1 mg/mL streptomycin (PSG, Sigma #G1146), and 500 ug/mL Geneticin (Invitrogen #10131)] in black-walled, clear-bottom 384-well poly-D-lysine-coated assay plates (Greiner Bio-One, Frickenhausen, Germany) and incubated in a humidified 5% CO2 incubator at 37° C. On the day of the assay, medium was removed by aspiration, and cells were washed with assay buffer [HBSS (Invitrogen, Carlsbad, Calif.) containing 20 mM HEPES (Invitrogen, Carlsbad, Calif.)]. After washing, 30 uL assay buffer containing the fluorescent voltage-sensor probe CC2-DMPE (Invitrogen, Carlsbad, Calif.) at 20 uM and 0.01% pluronic F-127 (Invitrogen, Carlsbad, Calif.) was added to the cells. Cells were incubated for 40 minutes at room temperature in the dark. Following the incubation, the cells were washed and 30 uL assay buffer containing 2.5 uM DiSBAC2(3) substrate (Invitrogen, Carlsbad, Calif.) and 0.5 mM VABSC-1 (Invitrogen, Carlsbad, Calif.) was added to the cells. The cells were incubated for 90 minutes at room temperature in the dark. Fluorescence readings were made using a FLIPR TETRA (Molecular Devices, Sunnyvale Calif.) equipped with voltage-sensor probe optics. At the start of each experiment the optimal (EC80) concentration of depolarizing agent (veratridine) was determined by testing a dilution curve of assay buffer containing veratridine (Sigma-Aldrich, St. Louis, Mo.) and 1 mg/mL scorpion venom (SVqq, from Leiurus quinquestriatus; Sigma-Aldrich, St. Louis, Mo.). Compounds were dissolved in dimethyl sulfoxide, and 8-point, 1:3 dilution concentration-response curves were prepared in duplicate in dimethyl sulfoxide, followed by preparation of 0.8 uL/well daughter plates of the dilutions. Test compounds in the daughter plate were diluted to (Ë¿3x) solutions in assay buffer immediately before assaying. Using the FLIPR TETRA, 20 uL of the (3x) compound solutions were first added to the cells, then 20 uL of depolarizing solution (3xEC80 veratridine+SVqq) were added 3 minutes later to activate the channel. Changes in fluorescence were measured at wavelengths of 440-480 nm and 565-625 nm over the course of the experimental run. Membrane depolarization was expressed as a ratio of the maximum F440-480 nm/F565-625 nm reading above average baseline F440-480 nm/F565-625 nm reading. IC50 values were calculated from curve fits of the ratio data using a four-parameter logistic Hill equation (Accelrys Assay Explorer 3.3 Client, Accelrys, San Diego, Calif.) with percent inhibition plotted against compound concentration.

Assay: Scintillation Proximity Assay (SPA): The binding of potential ligands to RORγ is measured by competition with [3H] 25-hydroxycholesterol (Perkin Elmer NET674250UC) using a scintillation proximity assay (SPA) binding assay. The ligand binding domain of human RORγ (A262-S507) with an N-terminal His tag is expressed in E. coli and purified using nickel affinity chromatography. 15 ug/well RORγ (A262-S507) is incubated with test compound at varying concentrations in 3-fold serial dilution, with final concentrations ranging from 16.6 uM to 0.28 nM for 10 min at room temperature in PBS buffer (Invitrogen #14190-144) containing 0.5% fatty acid free BSA (Gemini Bio-Products, Cat. #700-107P) and 0.1% Glycerol (Sigma Cat#G5516). 10 nM of [3H] 25-hydroxycholesterol is then added, and the reaction is incubated for 10 min. 10 mg/mL of Copper-His Tag-PVT beads (Perkin Elmer cat #RPNQ0095) are added, and the mixture is incubated for 60 min. The reaction is read on a TopCount Microplate scintillation plate reader (Perkin Elmer). The competition data of the test compound over a range of concentrations was plotted as percentage inhibition of radioligand specifically bound in the absence of test compound (percent of total signal). After correcting for non-specific binding, IC50 values were determined. The IC50 value is defined as the concentration of test compound needed to reduce [3H] 25-hydroxycholesterol specific binding by 50% and is calculated using the four parameter logistic equation to fit the normalized data.

UniProt: O00311
Assay: Inhibition Assay: 11 data point. Cdc7 kinase assays were carried out in 25 mM HEPES, pH 7.5, 1 mM DTT, 10 mM MgCl2, 100 μM Na3VO4, and 0.075 mg/ml Triton X-100 using 12 ng baculovirus-expressed Cdc7/Dbf4 and 2 μM Jerini peptide substrate A-A11 (biotin-C6linker-TPSDSLIYDDGLS) (SEQ ID NO:5). Reactions were initiated with λ-[33P]-ATP (1 μM, 20 mCi/μmol) and quenched after 1 hour with 5 volumes of stop buffer (50 mM EDTA, 2 M NaCl). The reactions were incubated for 30 minutes on streptavidin-coated plates, washed, and quantified using a TopCount scintillation plate reader (Packard). IC50 values are determined via non-linear regression fitting of the data. Ki values are generated assuming ATP-competitive (equilibrium) inhibition and using the experimentally determined apparent ATP Km of Cdc7 (0.7 μM).

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. According to the above assay, the GK activation capability of the exemplified compounds of the present invention was determined. The following table shows the results. Where different enantiomers of the same compound were tested, two numbers are provided. Where 3 numbers are provided, for example, Ex. #30, data for the racemic form is also shown.

Target: Alpha-synuclein (SINGLE PROTEIN), Homo sapiens
UniProt: P37840
Assay: In Vitro Inhibition Assay: α-Synucleinopathies are characterised by aggregation of α-synuclein in neurons. Aggregation of purified α-synuclein is performed essentially as described by Gerard et al. FASEB. 20(3):524-6 (2006). 20-100 μg purified α-synuclein (Sigma; S7820) at a concentration of about 2.5 μg/mL is incubated in the presence of spermin (250 μM) or paraquat (32 mM) or 6-hydroxydopamine (400 μM) or vehicle in a 384 well plate. Spermin, paraquat and 6-hydroxydopamine promote the α-synuclein aggregation process. Aggregation kinetics is determined by measuring turbidity at 340 nm, every 1-15 minutes for at least one hour.
