Erastin
Erastin is a small molecule capable of initiating ferroptotic cell death.[1] Erastin binds and inhibits VDAC2 and VDAC3[2] and functionally inhibits the cystine-glutamate antiporter system Xc-.[3] Cells treated with erastin are deprived of cysteine and are unable to synthesize the antioxidant glutathione. Depletion of glutathione eventually leads to excessive lipid peroxidation and cell death.
