Background
GPX4 24 is an inhibitor of glutathione peroxidase 4 (GPX4) and a derivative of (1S,3R)-RSL3 .1 It covalently binds to GPX4 in 4T1 murine mammary carcinoma cells in a concentration-dependent manner. GPX4 24 induces ferroptosis in GPX4-dependent HT-1080 fibrosarcoma cells (EC50 = 0.16 μM). It increases kidney and plasma malondialdede (MDA) levels in mice when administered at a dose of 200 mg/kg.
