[CAS NO. 347174-05-4]  Ferrostatin-1 (Fer-1)

Ferrostatin-1 (2 μM) prevents erastin-induced ferroptosis in cancer cells, as well as glutamate-induced cell death in postnatal rat brain slices. Ferrostatin-1 is a lipid ROS scavenger, with the N-cyclohexyl moiety serving as a lipo-philic anchor within biological membranes. Ferrostatin-1 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. Ferrostatin-1 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.
