  • Publication number: 20240002350
    Abstract: Disclosed are compounds and methods for preventing or treating necroinflammation associated with ferroptotic processes. The method includes inhibiting 15 lipoxygenase/phosphatidylethanolamine binding protein (15LOX/PEBP1) complex, wherein the inhibitor exhibits a higher binding affinity or binding activity for 15LOX/PEBP1 complex compared to 15LOX alone. Necroinflammation associated with ferroptotic processes causes several pathogenic conditions including upper or lower respiratory disorders, acute or chronic brain injury, renal injury, injury by radiation, neurodegenerative disorder, among others. The disclosed compounds and methods are useful in subjects diagnosed with one or more of these conditions.
