| Description | 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. | | Uses | 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. | | Uses | Reagent for inhibition of PARP. | | Uses | 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. | | Biochem/physiol Actions | 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. | | in vivo | DPQ (10 mg/kg; intraperitoneal injection; single dose; 6 h) significantly attenuates lung inflammation, neutrophil infiltration, and vascular leakage in LPS-induced acute lung injury model of C57BL/6 mice, inhibiting NF-κB pathway activation[2].
DPQ (10 mg/kg; intraperitoneal injection; single dose; 4 weeks) improves cardiac function and reduced apoptosis and oxidative stress in myocardial infarction model of Wistar rats[3].
| Animal Model: | LPS-Induced Acute Lung Injury Model in C57BL/6 mice (male, 8-10 weeks old) | | Dosage: | 10 μg/kg (dissolved in 0.01% DMSO (PBS) | | Administration: | Intraperitoneal injection, 30 min after LPS chanllenge (7.5 mg/kg; ip; single dose)
| | Result: | Reduced neutrophil infiltration (50% decrease), MPO activity (40% decrease), and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) in lungs.
Restored vascular permeability (Evans blue extravasation reduced by 35%), and inhibited apoptotic cell death (TUNEL-positive cells decreased by 45%).
Suppressed NF-κB activation with reduced IkB-α degradation and p65 phosphorylation. |
| Animal Model: |
Myocardial Infarction model in Wistar rats (male, 4 months old) via coronary artery ligation[3] | | Dosage: | 10 mg/kg (dissolved in DMSO)
| | Administration: | Intraperitoneal injection, single dose immediately after MI induction | | Result: | Improved cardiac function (FS increased by 25%, EDD/ESD reduced by 15%), decreased apoptotic cardiomyocytes (TUNEL-positive cells reduced by 40%), and suppressed cleaved caspase-3 and PARP1 expression. Oxidative stress markers (O2-, nitrotyrosine) were reduced by 30-40% in infarcted myocardium. |
