Assay: In Vitro Assays for IDH1m (R132H or R132C) Inhibitors: A test compound is prepared as 10 mM stock in DMSO and diluted to 50× final concentration in DMSO, for a 50 μl reaction mixture. IDH enzyme activity converting alpha-ketoglutarate to 2-hydroxyglutaric acid is measured using a NADPH depletion assay. In the assay the remaining cofactor is measured at the end of the reaction with the addition of a catalytic excess of diaphorase and resazurin, to generate a fluorescent signal in proportion to the amount of NADPH remaining. IDH1-R132H homodimer enzyme is diluted to 0.125 μg/ml in 40 μl of Assay Buffer (150 mM NaCl, 20 mM Tris-Cl pH 7.5, 10 mM MgCl2, 0.05% BSA, 2 mM b-mercaptoethanol) containing 5 μM NADPH and 37.5 μM NADP; 1 μl of test compound dilution in DMSO is added and the mixture is incubated for 60 minutes at room temperature. The reaction is started with the addition of 10 μl of Substrate Mix (20 μl NADPH, 5 mM alpha-ketoglutarate, in Assay Buffer) and the mixture is incubated for 60 minutes at room temperature. The reaction is terminated with the addition of 25 μl of Detection Buffer (36 μg/ml diaphorase, 30 mM resazurin, in 1× Assay Buffer), and is incubated for 1 minute before reading on a SpectraMax platereader at Ex544/Em590.Compounds are assayed for their activity against IDH1 R132C following the same assay as above with the following modifications: IDH1-R132C homodimer enzyme is diluted to 0.1875 μg/ml in 40 μl of Assay Buffer (50 mM potassium phosphate, pH 6.5; 40 mM sodium carbonate, 5 mM MgCl2, 10% glycerol, 2 mM b-mercaptoethanol, and 0.03% BSA) containing 5 uM NADPH and 28.75 uM NADP. The concentration of alpha-ketoglutarate in the Substrate Buffer is 1 mM.

Reaction product was determined quantitatively by TR-FRET after the addition of detection reagent Phycolink Streptavidin-allophycocyanin (Prozyme) and Europium-anti-mono- or di-methylated histone H3 lysine 4 (H3K4me1-2) antibody (PerkinElmer) in the presence of 5 mM EDTA in LANCE detection buffer (PerkinElmer) at a final concentration of 25 nM and 1 nM, respectively.The assay reaction was initiated by the following: 2 μl of the mixture of 900 nM H3K4me3-biotin labeled peptide and 6 μM alpha-ketoglutaric acid with 2 μl of 11-point serial diluted inhibitor in 3% DMSO was added to each well of plate, followed by the addition of 2 μl of 3 nM Jarid1A to initiate the reaction. The reaction mixture was incubated at room temperature for 30 minutes, and terminated by the addition of 6 μl of 5 mM EDTA in LANCE detection buffer containing 50 nM Phycolink Streptavidin-allophycocyanin and 2 nM Europium-anti-H3K4me1-2 antibody. Plates were read by EnVisionMultilabel Reader in TR-FRET mode (excitation at 320 nm, emission at 615 nm and 665 nm) after 1 hour incubation at room temperature. A ratio was calculated (665/615) for each well and fitted to determine inhibition constant (IC50).

UniProt: Q9UHD2
Assay: Kinase Assays: Kinase assays are commonly used for determining the ability of a small molecule to inhibit enzyme activity. By measuring the degree of phosphorylation of a substrate at varying concentrations of inhibitor, the concentration of inhibitor resulting in 50% enzymatic activity (IC50) can be obtained. The IC50 is defined as the inflection point of the sigmoidal graph obtained when plotting substrate phosphorylation vs. inhibitor concentration. Experiments were conducted during development of embodiments herein using radiolabeled ATP to detect substrate phosphorylation in the presence of amlexanox analogs to determine the potency (IC50) of said analogs.TBK1 (residues 1-657) and IKKε (residues 1-655) were purified from insect cells to ≥90% purity by coomassie staining. Reactions containing 50 nM TBK1 or IKKε, 7 μM myelin basic protein (MBP), and inhibitor in reaction buffer (50 mM HEPES pH 7.5, 10 mM NaCl, 10 mM MgCl2, 1 mM DTT) were initiated with 5 μM ATP spiked with [γ-32P]-ATP and allowed to proceed for 30 minutes at room temperature. Reactions were quenched with SDS gel loading dye, run on 4-15% SDS-PAGE gels, and imaged on phosphorimaging screens. Band intensities corresponding to phosphorylated MBP were quantified with ImageQuant and the data analyzed in Prism 6. Dose-response assay band intensities were normalized and fit to a sigmoidal dose-response equation with the Hill slope fixed at −1 and the top constrained to 100.

Assay: Jarid1B Assay: The ability of test compounds to inhibit the activity of Jarid1B was determined in 384-well plate format under the following reaction conditions: 0.8 nM Jarid1B, 300 nM H3K4me3-biotin labeled peptide (Anaspec cat #64357), 2 μM alpha-ketoglutaric acid in assay buffer of 50 mM HEPES, pH7.3, 0.005% Brij35, 0.5 mM TCEP, 0.2 mg/ml BSA, 50 μM sodium L-ascorbate, and 2 μM ammonium iron(II) sulfate. Reaction product was determined quantitatively by TR-FRET after the addition of detection reagent Phycolink Streptavidin-allophycocyanin (Prozyme) and Europium-anti-mono- or di-methylated histone H3 lysine 4 (H3K4me1-2) antibody (PerkinElmer) in the presence of 5 mM EDTA in LANCE detection buffer (PerkinElmer) at a final concentration of 25 nM and 1 nM, respectively. The assay reaction was initiated by the following: 2 μl of the mixture of 900 nM H3K4me3-biotin labeled peptide and 6 μM alpha-ketoglutaric acid with 2 μl of 11-point serial diluted inhibitor in 3% DMSO was added to each well of the plate, followed by the addition of 2 μl of 2.4 nM Jarid1B to initiate the reaction. The reaction mixture was incubated at room temperature for 30 minutes, and terminated by the addition of 6 μl of 5 mM EDTA in LANCE detection buffer containing 50 nM Phycolink Streptavidin-allophycocyanin and 2 nM Europium-anti-H3K4me1-2 antibody. Plates were read by EnVisionMultilabel Reader in TR-FRET mode (excitation at 320 nm, emission at 615 nm and 665 nm) after 1 hour incubation at room temperature. A ratio was calculated (665/615) for each well and fitted to determine inhibition constant (IC50).
