Tempol, a Superoxide Dismutase Mimetic Agent, Inhibits Superoxide Anion-Induced Inflammatory Pain in Mice
The present study evaluated the anti-inflammatory and analgesic effects of the superoxide dismutase mimetic agent tempol in superoxide anion-induced pain and inflammation. Mice were treated intraperitoneally with tempol (10-100 mg/kg) 40 min before the intraplantar injection of a superoxide anion donor, potassium superoxide (KO2, 30 μg). Mechanical hyperalgesia and thermal hyperalgesia, paw ede...
متن کاملCell-permeable scavengers of superoxide prevent long-term potentiation in hippocampal area CA1.
Long-term potentiation (LTP) in hippocampal area CA1 is generally dependent on N-methyl--aspartate (NMDA) receptor activation. Reactive oxygen species (ROS), including superoxide, are produced in response to NMDA receptor activation in a number of brain regions, including the hipppocampus. In this study, two cell-permeable manganese porphyrin compounds that mimic superoxide dismutase (SOD) were...
متن کاملDetermination of superoxide dismutase mimetic activity in common culinary herbs
BACKGROUND Under conditions of oxidative stress, the removal of superoxide, a free radical associated with chronic inflammation, is catalysed by superoxide dismutase (SOD). Thus in addition to acting as an antioxidant, SOD may also be utilized as an anti-inflammatory agent. Some plant derived foods have been shown to have SOD mimetic (SODm) activity however it is not known if this activity is p...
متن کاملTreatment with a SOD mimetic reduces visceral adiposity, adipocyte death and adipose tissue inflammation in high fat fed mice
OBJECTIVE Obesity is associated with enhanced reactive oxygen species (ROS) accumulation in adipose tissue. However, a causal role for ROS in adipose tissue expansion after high fat feeding is not established. The aim of this study is to investigate the effect of the cell permeable superoxide dismutase mimetic and peroxynitrite scavenger Mn(III)tetrakis(4-benzoic acid)porphyrin chloride (MnTBAP...
متن کاملPerylene Diimide as a Precise Graphene-like Superoxide Dismutase Mimetic
Here we show that the active portion of a graphitic nanoparticle can be mimicked by a perylene diimide (PDI) to explain the otherwise elusive biological and electrocatalytic activity of the nanoparticle construct. Development of molecular analogues that mimic the antioxidant properties of oxidized graphenes, in this case the poly(ethylene glycolated) hydrophilic carbon clusters (PEG-HCCs), will...
