PDD00017273

Descriptions

Biochem/physiol Actions

PDD00017273 is cell permeable in nature. It is used for specific killing of cells defective in certain homologous recombination (HR) proteins such as breast cancer gene 1/2 (BRCA1/2).

PDD00017273 is a potent and selective inhibitor of Poly(ADP-ribose) glycohydrolase (PARG), which catalyses hydrolysis of the O-glycosidic linkages of ADP-ribose polymers, reversing the effects of poly(ADP-ribose) polymerases (PARPs). PARG has been shown to be involved in the repair of single strand DNA breaks. PDD00017273 is selective for PARG, with EC₅₀ = 26 nM, compared to values of 30 µM for PARP1 and ARH3.
