Pelargonidin (PEL) is a well-known red pigment found in plants, and it has been reported to have important biological activities that are potentially beneficial for human health. This study was initiated to determine whether PEL could modulate renal functional damage in a mouse model of sepsis, and to elucidate the underlying mechanisms. The potential of PEL treatment to reduce renal damage induced by cecal ligation and puncture (CLP) surgery in mice was measured by assessment of serum creatinine, blood urea nitrogen (BUN), lipid peroxidation, total glutathione, glutathione peroxidase (GSH-Px) activity, catalase activity, and superoxide dismutase (SOD) activity. Treatment with PEL resulted in elevated plasma levels of BUN and creatinine, and of protein in urine in mice with CLP-induced renal damage. Moreover, PEL inhibited nuclear factor-κB activation and reduced the induction of nitric oxide synthase and excessive production of nitric acid. PEL treatment also reduced the plasma levels of interleukin-6 and tumor necrosis factor-α reduced lethality due to CLP-induced sepsis, increased lipid peroxidation, and markedly enhanced the antioxidant defense system by restoring the levels of SOD, GSH-Px, and catalase in kidney tissues. These results suggested that PEL protects mice against sepsis-triggered renal injury.
