Application

N-tert-Butyl-α-phenylnitrone has been used:
  • as a component of Dneasy Blood&Tissue buffer to preserve the oxidized state of DNA extracted from human non-tumorigenic epithelial breast (MCF10A) cells
  • as a free radical scavenger of reactive oxygen species (ROS) in microglial (MG) cell lines
  • to attenuate fibroblast senescence in unstable oral squamous cell carcinomas (GU-OSCC)

Actions biochimiques/physiologiques

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).
