Mechanism of Action

Targets/IC₅₀/Ki	Ferroptosis ^[1] (HT-1080 cells) 60 nM(EC50)
In vitro	Ferrostatin-1 (Fer-1) (2 μM) prevents erastin-induced ferroptosis in cancer cells, as well as glutamate-induced cell death in postnatal rat brain slices. It is a lipid ROS scavenger, with the N-cyclohexyl moiety serving as a lipo-philic anchor within biological membranes. This compound does not inhibit extracellular signal -regulated kinase (ERK) phos-phorylation or arrest the proliferation of HT-1080 cells, suggesting that it does not inhibit the MEK/ERK pathway, chelate iron, or inhibit protein synthesis. It does, however, prevent erastin-induced accumulation of cytosolic and lipid ROS. Ferrostatin-1 readily oxidizes the stable radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) under cell-free conditions. ^[1]
In vivo	Ferrostatin-1 (Fer-1), a synthetic antioxidant, is a potent and selective inhibitor of ferroptosis. It acts via a reductive mechanism to prevent damage to membrane lipids and thereby inhibits cell death.^[2]
