IC50 (binding) | = 51 nM | BindingDB_Patents: Enzyme Assay. A convenient method to determine IC50 of a PARP inhibitor compound is a PARP assay using purified recombinant human PARP from Trevigan (Gaithersburg, Md.), as follows: The PARP enzyme assay is set up on ice in a volume of 100 microliters consisting of 100 mM Tris-HCl (pH 8.0), 1 mM MgCl2, 28 mM KCl, 28 mM NaCl, 3.0 µg/ml of DNase I-activated herring sperm DNA (Sigma, Mo.), 30 micromolar [3H]nicotinamide adenine dinucleotide (62.5 mci/mmole), 15 micrograms/ml PARP enzyme, and various concentrations of the compounds to be tested. The reaction is initiated by adding enzyme and incubating the mixture at 25° C. After 2 minutes of incubation, the reaction is terminated by adding 500 microliters of ice cold 30% (w/v) trichloroacetic acid. The precipitate formed is transferred onto a glass fiber filter (Packard Unifilter-GF/C) and washed three times with 70% ethanol. After the filter is dried, the radioactivity is determined by scintillation counting. | 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.
