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.

Assay: In Vitro Assays for IDH2m R140Q Inhibitors: Compounds are assayed for IDH2 R140Q inhibitory activity through a cofactor depletion assay. Compounds are preincubated with enzyme and cofactor, then the reaction is started by the addition of α-KG, and allowed to proceed for 60 minutes under conditions previously demonstrated to be linear. The reaction is terminated by the addition of a second enzyme, diaphorase, and a corresponding substrate, resazurin. Diaphorase reduces resazurin to the highly fluorescent resorufin with the concomitant oxidation of NADPH to NADP, both halting the IDH2 reaction by depleting the available cofactor pool and facilitating quantitation of the amount of cofactor remaining after a specific time period through quantitative production of an easily detected fluorophore.Specifically, into each of 12 wells of a 384-well plate, 1 μl of 50× compound dilution series is placed, followed by the addition of 40 μl of buffer (50 mM potassium phosphate (K2HPO4), pH 7.5; 150 mM NaCl; 10 mM MgCl2, 10% glycerol, 0.05% bovine serum albumin, 2 mM beta-mercaptoethanol) containing 0.39 μg/ml IDH2 R140Q protein, 5 uM NADPH and 750 uM NADP. The test compound is then incubated for 16 hrs at room temperature with the enzyme and cofactors before starting the IDH2 reaction with the addition of 10 μl of substrate mix containing 8 mM α-KG (final concentration 1.6 mM) in the buffer described above. After a further 1 hour of incubation at room temperature, the reaction is halted and the remaining NADPH measured through conversion of resazurin to resorufin by the addition of 25 μl Stop Mix (36 μg/ml diaphorase enzyme and 60 μM resazurin; in buffer). After one minute of incubation the plate is read on a plate reader at Ex544/Em590.

Assay: In Vitro Assays for IDH2m R140Q Inhibitors: Compounds are assayed for IDH2 R140Q inhibitory activity through a cofactor depletion assay. Compounds are preincubated with enzyme and cofactor, then the reaction is started by the addition of α-KG, and allowed to proceed for 60 minutes under conditions previously demonstrated to be linear. The reaction is terminated by the addition of a second enzyme, diaphorase, and a corresponding substrate, resazurin. Diaphorase reduces resazurin to the highly fluorescent resorufin with the concomitant oxidation of NADPH to NADP, both halting the IDH2 reaction by depleting the available cofactor pool and facilitating quantitation of the amount of cofactor remaining after a specific time period through quantitative production of an easily detected fluorophore.Specifically, into each of 12 wells of a 384-well plate, 1 μl of 50× compound dilution series is placed, followed by the addition of 40 μl of buffer (50 mM potassium phosphate (K2HPO4), pH 7.5; 150 mM NaCl; 10 mM MgCl2, 10% glycerol, 0.05% bovine serum albumin, 2 mM beta-mercaptoethanol) containing 0.39 μg/ml IDH2 R140Q protein, 5 uM NADPH and 750 uM NADP. The test compound is then incubated for 16 hrs at room temperature with the enzyme and cofactors before starting the IDH2 reaction with the addition of 10 μl of substrate mix containing 8 mM α-KG (final concentration 1.6 mM) in the buffer described above. After a further 1 hour of incubation at room temperature, the reaction is halted and the remaining NADPH measured through conversion of resazurin to resorufin by the addition of 25 μl Stop Mix (36 μg/ml diaphorase enzyme and 60 μM resazurin; in buffer). After one minute of incubation the plate is read on a plate reader at Ex544/Em590.

Assay: In Vitro Assays for IDH2m R140Q Inhibitors: Compounds are assayed for IDH2 R140Q inhibitory activity through a cofactor depletion assay. Compounds are preincubated with enzyme and cofactor, then the reaction is started by the addition of α-KG, and allowed to proceed for 60 minutes under conditions previously demonstrated to be linear. The reaction is terminated by the addition of a second enzyme, diaphorase, and a corresponding substrate, resazurin. Diaphorase reduces resazurin to the highly fluorescent resorufin with the concomitant oxidation of NADPH to NADP, both halting the IDH2 reaction by depleting the available cofactor pool and facilitating quantitation of the amount of cofactor remaining after a specific time period through quantitative production of an easily detected fluorophore.Specifically, into each of 12 wells of a 384-well plate, 1 μl of 50× compound dilution series is placed, followed by the addition of 40 μl of buffer (50 mM potassium phosphate (K2HPO4), pH 7.5; 150 mM NaCl; 10 mM MgCl2, 10% glycerol, 0.05% bovine serum albumin, 2 mM beta-mercaptoethanol) containing 0.39 μg/ml IDH2 R140Q protein, 5 uM NADPH and 750 uM NADP. The test compound is then incubated for 16 hrs at room temperature with the enzyme and cofactors before starting the IDH2 reaction with the addition of 10 μl of substrate mix containing 8 mM α-KG (final concentration 1.6 mM) in the buffer described above. After a further 1 hour of incubation at room temperature, the reaction is halted and the remaining NADPH measured through conversion of resazurin to resorufin by the addition of 25 μl Stop Mix (36 μg/ml diaphorase enzyme and 60 μM resazurin; in buffer). After one minute of incubation the plate is read on a plate reader at Ex544/Em590.

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: O75164
Assay: Activity Assay: The ability of test compounds to inhibit the activity of JMJD2A was determined in 384-well plate format under the following reaction conditions: 2 nM JMJD2A, 300 nM H3K9me3-biotin labeled peptide (Anaspec cat #64360), 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-di-methylated histone H3 lysine 9 (H3K9me2) antibody (PerkinElmer) in the presence of 5 mM EDTA in LANCE detection buffer (PerkinElmer) at a final concentration of 50 nM and 1 nM, respectively.The assay reaction was initiated by the following: 2 μl of the mixture of 900 nM H3K9me3-biotin labeled peptide and 6 μM alpha-ketoglutaric acid with 2 μl of 11-point serial diluted inhibitor in 3% DMSO were added to each well of plate, followed by the addition of 2 μl of 6 nM JMJD2A 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 100 nM Phycolink Streptavidin-allophycocyanin and 2 nM Europium-anti-H3K9me2 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).
