IC50 (binding) | = 6407 nM | BindingDB_Patents: LC-MS Biochemical Assay. Mutant IDH1 R132H catalytic activity was monitored using the quantitative liquid chromatography/mass spectrometry (LC-MS) detection of 2-HG, a product of the NADPH-dependent alpha-KG reduction reaction.More specifically, the biochemical reactions were performed at room temperature in 384-well Greiner flat-bottom plates (Costar, Cat. No. 781201) using a final reaction volume of 30 uL and the following assay buffer conditions: 50 mM HEPES pH 7.4, 10 mM MgCl2, 50 mM KCl, 1 mM DTT, 0.02% BSA, 5 uM NADPH and 100 uM alpha-KG.The final reaction mixture contained 3.3% DMSO and inhibitors with concentrations ranging 0.02-50 uM. The IDH1 enzyme was used at a final concentration of 0.25 nM. Following 45 minutes incubation, the reaction mixtures were quenched by the addition of 10 uL of 16% formic acid containing 800 nM of 5-carbon labeled 13C-2-HG). The protein was then precipitated by the addition of 2.5 volumes of acetonitrile followed by centrifugation (3000xg, 20 minutes). | ChEMBL. | No reference |

IC50 (binding) | = 9780 nM | BindingDB_Patents: Fluorescence Biochemical Assay. The IDH1 (R132H) mutant catalyzes the reduced form of NADP+ (NADPH) and a-ketoglutarate (a-KG) to form nicotinamide adenine dinucleotide phosphate (NADP+) and R (-)-2-hydroxyglutarate (2HG). The reaction can be monitored kinetically by following the oxidation of NADPH to NADP+ which is measured using fluorescence, excitation at 355 nm and emission at 530 nm. Reactions were monitored using the Perkin-Elmer Envision, Model 2101. More specifically, the biochemical reactions were performed at room temperature in 384-well Greiner flat-bottom plates (Cat. No. 781076) using a final reaction volume of 20 µL and the following assay buffer conditions: 50 mM HEPES pH 7.5, 10 mM MgCl2, 1 mM DTT, 0.02% BSA, 0.02% Tween-20, 10 µM NADPH and 100 µM a-KG. The final reaction mixture contained 2.5% DMSO and test compounds with concentrations ranging 0.0000008-25 µM.

Many chemical entities in TDR Targets come from high-throughput screenings with whole cells or tissue samples, and not all assayed compounds have been tested against a single a single target protein, probably because they get ruled out during screening process. Even if these compounds may have not been of interest in the original screening, they may come as interesting leads for other screening assays. Furthermore, we may be able to propose drug-target associations using chemical similarities and network patterns.
