Liproxstatin-1 is a potent inhibitor of ferroptosis, a non-apoptotic form of cell death characterized by iron-dependent accumulation of lethal lipid reactive oxygen species (ROS). Ferroptosis is a non-apoptotic form of cell death induced by small molecules in specific tumour types, and in engineered cells overexpressing oncogenic RAS.

Liproxstatin-1 shows antiferroptotic activity with an IC50 of approximately 38 nM in mouse embryonic fibroblasts.
Liproxstatin-1 (10 mg/kg, i.p.) suppresses ferroptosis in human cells, Gpx4−/− kidney and in an ischaemia/reperfusion-induced tissue injury model.
