N-tert-butyl-α-phenylnitrone (PBN) is a commonly used free-radical spin trap.
N-tert-butyl-α-phenylnitrone (PBN) is a commonly used free-radical spin trap. It has been shown to reduce the number of emboli-induced cerebral microinfarctions in the rabbit cortex and prevent neoplasia by its radical scavenging activity and its ability to inhibit cyclooxygenase-2 activity. Reported to inhibit the induction of nitric oxide synthase (iNOS), thereby preventing the overproduction of nitric oxide (NO). PBN in a dose of 100 mg/kg i.p. reduced necrosis of the substantia nigra, pars reticulate in flurothyl-induced status epilepticus in rats. It protects against some types of post-trauma epileptogenic events in an animal model of epilepsy. The lethal dose of PBN in rats was found to be approximately 100 mg/100 g body weight (0.564 mmol/100Å g).

Oxidative stress after stroke is associated with the inflammatory system activation in the brain. The complement cascade, especially the degradation products of complement component 3, is a key inflammatory mediator of cerebral ischemia. We have shown that pro-inflammatory complement component

The purpose of this study was to determine the pathological importance of oxidative stress-induced injurious processes in chagasic heart dysfunction. Trypanosoma cruzi-induced inflammatory pathology and a feedback cycle of mitochondrial dysfunction and oxidative stress may contribute to Chagas disease. Sprague-Dawley
