8-Hydroxy-2-Anilino-1,4-Naphthoquinone Prevents Against Ferroptotic Neuronal Death and Kainate-Induced Epileptic Seizures.

ABSTRACT: Background/Objectives: Ferroptosis, an iron-dependent form of regulated cell death characterized by excessive lipid peroxidation, has been implicated in various acute and chronic brain disorders, including epilepsy. Although 1,4-naphthoquinone derivatives have been reported to regulate ferroptosis, their mechanistic roles in the nervous system remain underexplored. Here, we investigated the protective effects of 8-hydroxy-2-anilino-1,4-naphthoquinone (8-HANQ) on ferroptotic neuronal death in vitro and seizure behaviors in vivo. Methods: HT22 hippocampal cells were exposed to ferroptosis inducers including glutamate, glutamate plus iron, or RSL3. Lipid reactive oxygen species (ROS), ferroptosis markers, and its related molecules were assessed by flow cytometry and Western blot
