Polydatin, known as a PLA2 inhibitor, reduces Phospholipase A2 (PLA2) activity and sPLA2-IIA mRNA expression and mitigates LPS-induced lung injury by increasing increased Clara cell secretory protein (CCSP) expression.
In vivo
Pretreatment with Polydatin (15, 45, and 100 mg/kg) dose-dependently reduces sepsis-induced mortality and lung injury in cecal ligation and puncture (CLP-)induced sepsis mice through inhibiting CLP-induced serum tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) production, lung cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase isoform (iNOS) protein expressions and NF-kappaB activation.
