title: The effect of caffeic acid phenethyl ester on ischemia-reperfusion injury in comparison with alpha-tocopherol in rat kidneys.
abstract: Oxygen-derived free radicals have been implicated in the pathogenesis of renal injury after ischemia-reperfusion. Caffeic acid phenethyl ester (CAPE), an active component of propolis extract, exhibits antioxidant and anti-inflammatory properties. To determine whether CAPE offers any advantage over alpha-tocopherol, we compared their effects on an in vivo model of renal ischemia-reperfusion injury in rats. CAPE at 10 micromol/kg or alpha-tocopherol at 10 mg/kg was administered intraperitoneally before reperfusion. Acute administration of CAPE suppressed ischemia-reperfusion induced renal lipid peroxidation and tissue injury more than alpha-tocopherol. CAPE may therefore offer a therapeutic advantage in acute injury settings.
