2-PIPERAZINE-4-AMINO-6,7-DIMETHOXY QUINOLINE HYDROCHLORIDE Chemical Properties,Usage,Production

Uses

DPQ hydrochloride is a blood-brain barrier permeable and selective PARP-1 inhibitor that blocks PARP-1-mediated DNA damage repair and NAD+/ATP consumption, thereby inhibiting excessive inflammatory responses. DPQ hydrochloride inhibits NF-κB pathway activation, reduces the expression of pro-inflammatory factors (such as TNF-α, IL-6) and oxidative stress. DPQ hydrochloride can be used in inflammation-related studies of acute lung injury, myocardial infarction, and neurodegenerative diseases[1][2][3].

in vivo

DPQ hydrochloride (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 hydrochloride (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)[2]
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:Wistar rats (male, 4 months old) + MI 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.

IC 50
