IC50 (binding) | = 7.046 | Inhibition of Homo sapiens (human) dehydroorotate dihydrogenase using 2,6-dichlorophenol-indophenol as substrate after 10 min by spectrophotometric analysis | ChEMBL. | No reference |
IC50 (binding) | = 90 nM | BindingDB_Patents: Inhibition Assay. DHODH activity and its inhibition were studied using a chromogen reduction assay with DCIP (2,6-dichlorophenol-indophenol). The substrate oxidation (Dihydroorotate, L-DHO), as well as cosubstrate reduction (coenzyme Q, CoQ) is coupled to the chromogen reduction, hence enzymatic activity results in a loss of chromogen absorbance at 600 nm. Enzyme extracts (8 µl, 1.5 µg of human protein) were incubated in 96-well plates. The assay mixture (200 µl) contained 200 µM CoQD, 100 µM L-DHO, 120 µM DCIP in the assay buffer (100 mM HEPES pH 8.0, 150 mM NaCl, 10% Glicerol, 0.05% Triton X-100) and 2 µl of test compound. The compounds were dissolved in DMSO at a stock concentration of 1 mM, and tested at different concentrations varying from 10 µM to 1 µM to calculate an IC50 (concentration of inhibitor required for 50% of inhibition). | ChEMBL. | No reference |

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.
