Tool Details

  • Tool name: PARG inhibitor PDD00017273 Small Molecule (Tool Compound)
  • Alternate names: Poly(ADP-ribose) glycohydrolase
  • Molecular formula: C23H26N6O4S2
  • Tool type: Small molecules
  • Tool sub-type: Inhibitor
  • Purpose: Inhibitor
  • Molecular weight of the target: 514.62
  • Description: Poly(ADP ribose) glycohydrolase (PARG) has been shown to be a critical component in the repair of single strand DNA breaks. PARG counteracts the function of the ARTD family of poly(ADP ribose) polymerases, commonly known as PARPS, by efficiently catalysing the hydrolysis of O-glycosidic linkages of ADP-ribose polymer, thereby reversing the effects of PARPs. As PARG exists as a single protein, it presents an attractive target for therapeutic intervention in cancer cells with enhanced dependence upon DNA repair.
