1-{3-[2-(1-Benzothiophen-5-yl)ethoxy]propyl}-3-azetidinol maleate (T-817MA), a novel neurotrophic agent, protects against amyloid-beta peptide- or hydrogen peroxide-induced neuronal death. The exact mechanism of the neuroprotection is not known. This study examines the effects of T-817MA on oxidative stress-induced cytotoxicity in primary rat cortical neurons. ⋯ In addition, the agent reduced SNP-induced increase in mitochondrial reactive oxygen species (ROS) production. The effects of T-817MA on SNP-induced decrease in cell viability and SNP-induced increase in mitochondrial ROS production were blocked by cycloheximide. These results suggest that T-817MA improves SNP-induced mitochondrial dysfunction in cortical neurons in a newly synthesized protein-mediated mechanism and this effect contributes to its neuroprotective effect.
