Biological Activity
PDD 00017273 is a potent inhibitor of PARG, with an IC50 of 26 nM, and a KD of 1.45 nM. PDD 00017273 (10 μM) does not inhibit five common Cytochrome P450 enzymes. PDD 00017273 (30 μM) modestly increasess phosphorylated H2AX (γH2AX) intensity, PDD 00017273 also decreases in NAD/H through PARG inhibition after DNA damage. PDD 00017273 suppresses the ZR-75-1 cells carring BRCA1 and BRCA2 wild type, and exhibits less potent activities against MDA-MB-436 cells carry the 5396 + 1G>A mutation in BRCA1[1]. PDD 00017273 (0.3 μM) inhibits degradation of PAR polymers in MCF7 cells. PDD 00017273 (0.3 μM) also reduces the viability of BRCA1, BRCA2, PALB2, FAM175A, and BARD1 depleted cells. PDD 00017273 stalls replication forks and induces DNA damage that requires homologous recombination (HR) for repair[2].

Protocol
Briefly, PARG in vitro assays are conducted in a total volume of 15 μL in a standard 384-well format. A total of 5 μL of human full length PARG used at a final reaction concentration of 65 pM, is added to 5 μL of Bt-NAD ribosylated PARP1 substrate at a final reaction concentration of 4.8 nM in assay buffer (50 mM Tris pH 7.4, 0.1 mg/mL BSA, 3 mM EDTA, 0.4 mM EGTA, 1 mM DTT, 0.01% Tween 20, 50 mM KCl). The reaction is incubated at RT for 10 min, and then 5 μL of detection reagent is added. Detection reagent consists of 42 nM mAb anti-6HIS XL665 and 2.25 nM streptavidin europium cryptate, both at 3× working stock concentrations (final concentrations of 14 nM and 0.75 nM, respectively), in detection buffer (50 mM Tris pH 7.4, 0.1 mg/mL BSA and 100 mM KF). Following incubation at RT for 60 min in the dark, TR-FRET signal is measured at λEx 340 nm and λEm 665 nm and λEm 620 nm using a PHERAstar FS plate reader. The ratio is calculated as [Em665/EM620] × 104 for each well and used to calculate percent inhibition for test compounds[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
HeLa cells are seeded in 30 μL of media at 1 × 104 cells/mL in Greiner 384-well plates. A total of 16-24 h later, cells are treated with inhibitors (8 pt dose response, 0.01-30 μM, triplicates) or vehicle (DMSO) control. The outer wells are left undosed to account for edge effects. After 72 h, 50 μL of 3.7% formaldehyde/PBS is added to each well, and cells are fixed for 20 min. Cells are then rinsed twice with PBS and stained for 1 h with Hoechst 33342/PBS (1:2000) in the dark. After two further rinses with PBS, images are captured and nuclei counted on a CellInsight. The maximum number of fields are captured from each triplicate well, which approximated to at least 1000 nuclei in vehicle-dosed wells[1].
