Target: Indoleamine 2,3-dioxygenase 1 (SINGLE PROTEIN), Homo sapiens
UniProt: P14902
Assay: In-vitro IDO1 Enzyme (Indoleamine 2,3-dioxygenase) Assay: Human indoleamine 2,3-dioxygenasel (hIDO1) catalyzes the oxidative cleavage of the pyrrole ring of the indole nucleus of tryptophan to yield N-formylkynurenine which can be converted to kynurenine (KYN) by deformylation. hIDO1 with an N-terminal His tag, expressed and purified from E. coli cells was procured from either Enzo LifeScienccs, NY, USA). Unless otherwise stated, all materials were procured from Sigma Aldrich, Mo., USA.The assay monitoring the conversion of L-tryptophan to KYN was carried out as follows. hIDO1 (10 nM) was incubated with tryptophan (30 μM) in the presence of ascorbic acid (20 mM), methylene blue (10 μM) and catalase (100 μg/mL) in potassium phosphate buffer (50 mM; pH 6.5) at 37C for 30 min. The reaction was terminated with 30% trichloroacetic acid (TCA) and further incubated at 65C for 15 min to fully convert N-formylkynurenine to KYN. The reaction mixture was then centrifuged to remove sediments and the KYN in the supernatant was estimated by UV-visible absorption spectroscopy at 360 nm using a Waters HPLC system fitted with a C-18 column or by LC/MS/MS. See, Sono, 1980, J. Biol. Chem., 255:1339-1345, which is herein incorporated by reference.Percent inhibition at each concentration of test compounds was determined by estimating the decrease in KYN with reference to the reaction control with 1% DMSO vehicle. Data were analyzed using nonlinear regression to generate IC50 values using Graph Pad Prism 5.

Assay: In Vitro Assays for IDH1m (R132H or R132C): The following describes the experimental procedures that can be used to obtain data on columns 3 and 6 of Table 4.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-R132 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); 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 90 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: Assay Buffer is (50 mM potassium phosphate, pH 6.5; 40 mM sodium carbonate, 5 mM MgCl2, 10% glycerol, 2 mM b-mercaptoethanol, and 0.03% BSA). The concentration of NADPH and alpha-ketoglutarate in the Substrate Buffer is 20 μM and 1 mM, respectively.

Assay: High Throughput Fluorescence Displacement Assay : FABP5 was purified and delipidated as described previously (Kaczocha, M. et al. 2012). FABP5 (30 μg), NBD-stearate (1 μM), and a competitor test compound were incubated in 30 mM Tris-HCl, 100 mM NaCl buffer (pH 7.6). Competitors included arachidonic acid, BMS309403, 48 test compounds from ChemDiv library, Compound 26 and Compound 49. The initial assay was run with buffer (30 mM Tris-HCl buffer), negative controls (buffer and NBD-stearate), positive controls (buffer, NBD-stearate, FABP5), and experimental wells with a variable test compound added (arachidonic acid or one of the 48 test compounds) at 10 μM. Test compounds that produced high inhibition and proved statistically significant were then added to the fluorescent assay at 10 μM and tested in triplicate to verify their success. The most effective test compound and BMS309403 were measured in increasing concentrations (0.01-50 μM), as were the Compound 26 and γ-truxillic acid 1-naphthyl ester, which were discovered following the test. The fluorescent assays were tested in the wells of Microtest 96-well Assay Plates, Optilux (BD Biosciences, Franklin Lakes, N.J.) and loss of fluorescence intensity was measured with a FLUOstar OPTIMA spectrofluorometer set to excitation and emission wavelengths of 460 nm and 544 nm, respectively. For the most effective test compounds, IC50 values were calculated with GraphPad Prism. GraphPad Prism was also used to determine the Ki of these select competitors from the equation Ki=IC50/(1+([NBD-stearate]/Kd)).

Assay: In Vitro Enzyme Inhibition Assay: The enzymatic assay of Jarid1A activity is based upon Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) detection. The ability of test compounds to inhibit the activity of Jarid1A was determined in 384-well plate format under the following reaction conditions: 1 nM Jarid1A, 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 plate, followed by the addition of 2 μl of 3 nM Jarid1A to initiate the reaction. The reaction mixture was incubated at room temp for 30 min, 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 hr incubation at room temp. A ratio was calculated (665/615) for each well and fitted to determine inhibition constant (IC50).

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: Jarid1A Assay: The enzymatic assay of Jarid1A activity is based upon Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) detection. The ability of test compounds to inhibit the activity of Jarid1A was determined in 384-well plate format under the following reaction conditions: 1 nM Jarid1A, 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 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).

Assay: High Throughput Fluorescence Displacement Assay : FABP5 was purified and delipidated as described previously (Kaczocha, M. et al. 2012). FABP5 (30 μg), NBD-stearate (1 μM), and a competitor test compound were incubated in 30 mM Tris-HCl, 100 mM NaCl buffer (pH 7.6). Competitors included arachidonic acid, BMS309403, 48 test compounds from ChemDiv library, Compound 26 and Compound 49. The initial assay was run with buffer (30 mM Tris-HCl buffer), negative controls (buffer and NBD-stearate), positive controls (buffer, NBD-stearate, FABP5), and experimental wells with a variable test compound added (arachidonic acid or one of the 48 test compounds) at 10 μM. Test compounds that produced high inhibition and proved statistically significant were then added to the fluorescent assay at 10 μM and tested in triplicate to verify their success. The most effective test compound and BMS309403 were measured in increasing concentrations (0.01-50 μM), as were the Compound 26 and γ-truxillic acid 1-naphthyl ester, which were discovered following the test. The fluorescent assays were tested in the wells of Microtest 96-well Assay Plates, Optilux (BD Biosciences, Franklin Lakes, N.J.) and loss of fluorescence intensity was measured with a FLUOstar OPTIMA spectrofluorometer set to excitation and emission wavelengths of 460 nm and 544 nm, respectively. For the most effective test compounds, IC50 values were calculated with GraphPad Prism. GraphPad Prism was also used to determine the Ki of these select competitors from the equation Ki=IC50/(1+([NBD-stearate]/Kd)).
