Effect of 3-butyl-1-phenyl-2-(phenyltelluro)oct-en-1-one on oxidative stress in cerebral cortex of rats.

The objective of this study was to verify the effect of the organochalcogen 3-butyl-1-phenyl-2-(phenyltelluro)oct-en-1-one on some parameters of oxidative stress in the brain of 10-day-old rats. Cerebral cortex was incubated for 1h in the presence or absence of 1, 10 or 30 microM of 3-butyl-1-phenyl-2-(phenyltelluro)oct-en-1-one and thiobarbituric acid reactive substances (TBARS), carbonyl, sulfhydryl, catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione S-transferase (GST), nitric oxide (NO) production and the release of the cytosolic enzyme lactate dehydrogenase (LDH) were measured. The organotellurium was not capable to alter TBARS and carbonyl assays.
