Drugging the ferroptotic landscape of Friedreich’s Ataxia: Current paradigms and future directions

Cravin G, Cozza G. Drugging the ferroptotic landscape of Friedreich’s Ataxia: Current paradigms and future directions. Ferroptosis Oxid Stress. 2026;2:202618. doi:10.70401/fos.2026.0032 

 In the present review, we explore how FXN loss undermines cellular defenses against oxidative damage, placing a specific focus on the regulation of the lipid redox landscape. We detail the breakdown of glutathione (GSH)-dependent mechanisms, specifically highlighting the blunted Nrf2 antioxidant response and the subsequent reduced capacity of glutathione peroxidase 4. Alongside these deficits, we investigate the compensatory roles of GSH-independent rescue networks, namely ferroptosis suppressor protein 1 and mitochondrial dihydroorotate dehydrogenase. Looking toward clinical translation, we critically assess emerging pharmacological interventions designed to target these ferroptotic nodes. The potential of mitochondria-targeted iron chelators, lipoxygenase inhibitors, lipophilic radical-trapping antioxidants, and novel Nrf2 activators is evaluated to determine whether inhibiting ferroptosis can serve as a viable disease-modifying strategy. Moving forward, combinatorial “protect and restore” approaches will likely prove essential for maximizing therapeutic efficacy in FRDA.
