The poly(ADP-ribose) polymerases (PARPs) form a family of enzymes with roles in DNA repair and apoptosis, particularly in response to reactive oxygen and nitrogen species. DPQ is a potent inhibitor of PARPs, inhibiting PARP1 with an IC50 value of 40 nM. It is approximately 10-fold less potent against PARP2. DPQ can be used in either cells or in animals.
DPQ has been used as a PARP1 (poly(ADP-ribose) polymerase 1) inhibitor in in vivo studies to determine the loss of γ-H2AX (H2A histone family member X) upon irradiation.
Reagent for inhibition of PARP.
3,4-Dihydro-5-[4-(1-piperidinyl)butoxy]-1(2H)-isoquinolinone is a potent inhibitor of poly(ADP-ribose) polymerases, a family of enzymes that plays a crucial role in DNA repair and apoptosis in respons
e to reactive oxygen and nitrogen species.
3,4-Dihydro-5-[4-(1-piperidinyl)butoxyl]-1(2H)-isoquinolinone (DPQ) is known to decrease the PARP 1 (poly(ADP-ribose) polymerase 1) mediated apoptosis under the influence of ischemia. It is considered as more effective inhibitor than the traditionally used PARP1 inhibitor 3-aminobenzamide.
