Ferrostatin-1 (Fer-1) is a potent inhibitor of ferroptosis with an EC50 ~60 nM, identified by a HTS using erastin-induced ferroptosis in HT-1080 cells. Ferroptosis is a unique iron-dependent form of nonapoptotic cell death triggered by the oncogenic RAS-selective lethal small molecule erastin. Ferroptosis is dependent upon intracellular iron, but not other metals, and is morphologically, biochemically, and genetically distinct from apoptosis, necrosis, and autophagy. Ferrostatin-1 was shown to inhibit ferroptosis in cancer cells, and also glutamate-induced cell death in organotypic rat brain slices. Studies revealed that erastin blocks cystine uptake via inhibition of the cystine/glutamate antiporter, resulting in a defect in the cell’s antioxidative defenses and ultimately leading to an iron-dependent, oxidative cell death (i.e., ferroptosis). Ferrostatin-1 was characterized to prevent erastin-induced accumulation of cytosolic and lipid ROS. Ferrostatin-1 serves as a very useful tool to dissect ferroptosis in cancer and many other cell types, and may provide new opportunities to protect tissues and organs from damages resulted from ferroptosis under diseases (such as neurodegeneration).

How to use
Ferrostatin-1 (Fer-1) prevents erastin-induced accumulation of cytosolic and lipid ROS. Ferrostatin-1 prevents glutamate-induced neurotoxicity in organotypic rat brain slices. Fer-1 inhibited lipid peroxidation, but not mitochondrial reactive oxygen species formation or lysosomal membrane permeability.
Ferrostatin-1 inhibits cell death in cellular models of Huntington's disease (HD), periventricular leukomalacia (PVL), and kidney dysfunction. Ferrostatin-1 (0.8 mg/kg; tail vein injection) effectively alleviated LPS-induced induced acute lung injury (ALI). Ferrostatin-1 (i.p.; 5 mg/kg; C57BL/6J mice) improves renal function in mice with rhabdomyolysis.
