DPQ
Based on 4 publication(s) in Google Scholar
DPQ is a selective PARP-1 inhibitor that blocks PARP-1-mediated DNA damage repair and NAD+/ATP consumption, thereby inhibiting excessive inflammatory responses. DPQ inhibits NF-κB pathway activation, reduces the expression of pro-inflammatory factors (such as TNF-α, IL-6) and oxidative stress. DPQ can be used in inflammation-related studies of acute lung injury, myocardial infarction, and neurodegenerative diseases.

PARP-1 |
DPQ (10 μM; pretreatment 30 min, treatment 2-8 h) significantly inhibits the mRNA expression of TNF-α, IL-1β, IL-6, CXCL-1, MIP-2 and iNOS in mouse peritoneal macrophages stimulated by LPS (100 ng/mL) [2].
DPQ (10 μM; pretreatment 30 min, treatment 2-8 h) inhibits the degradation of IkB-α and phosphorylation of NF-κB p65 in macrophages induced by LPS (100 ng/mL)，blocking the inflammatory signaling pathway[2].

-
Cell Line:Mixed murine cortical neurons
-
Concentration:10 μM
-
Incubation Time:10 min pretreatment + 20 min NMDA exposure
-
Result:Reduced NMDA-induced neuronal apoptosis by 84% at 6 h and 50% at 24 h, restored ATP levels from 4% to 72% of control, and suppressed PARP activation.
-
Cell Line:Murine peritoneal macrophages
-
Concentration:10 μM
-
Incubation Time:30 min pretreatment + 2-8 h LPS stimulation
-
Result:Significantly decreased LPS-induced mRNA expression of TNF-α (50% reduction), IL-1β (40%), IL-6 (45%), CXCL-1 (35%), MIP-2 (40%), and iNOS (50%).
-
Cell Line:Murine peritoneal macrophages
-
Concentration:10 μM
-
Incubation Time:30 min pretreatment + 15-60 min LPS stimulation
-
Result:Blocked LPS-induced IkB-α degradation (50% inhibition at 15 min) and NF-κB p65 phosphorylation (40% reduction at 30 min).
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%).
