| Abstract | Protective effects of EPC-Ki (L-ascorbic acid 2-[3,4-dihydro-2,5,7,8-tetramethyl-2-(4,8,12trimethyldecyl)-2H-I-benzopyran-6-yl-hydrogen phosphate] potassium salt, a difunctional derivative of vitamin C and vitamin E) on neuronal cell damage mediated by peroxynitrite were studied. Primary cultures of cerebellar granule cells were exposed to peroxynitrite by treatment with 3morpholinosydnonimine-N-ethylcarbamide (SIN-I), which generated nitric oxide and superoxide anion simultaneously upon decomposition. The results showed that SIN-I trealment lriggered time-dependent cell death, which was accompanied by the decrease in the cellular GSH level, the increase in the lipid peroxidation level, and the alteration of cell membrane biophysical characteristics. EPC-KI showed only moderate scavenging effect on peroxynitrite, but could effectively protect neuronal cells from oxidative damage mediated by peroxynitrite. |
