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.
