Erastin

Erastin, named for eradicator of RAS and small T (ST) antigen-expressing cells, is a ferroptosis inducer. It induces ferroptotic cell death in vitro, an effect that can be blocked by the ferroptosis inhibitors ciclopirox olamine, Trolox (Cay-10011659), ferrostatin-1 (Cay-17729), U-0126 (Cay-70970), cycloheximide (Cay-14126), and beta-mercaptoethanol. Erastin (5 µM) inhibits cystine uptake by the system xc- cystine-glutamate transporter in HT-1080 fibrosarcoma and Calu-1 lung carcinoma cells and inhibits glutamate release in an enzyme-coupled fluorescence assay (EC50 = 1.2 µM). It also selectively induces cell death in cells expressing the SV40 small T oncoprotein and oncogenic Ras (IC50s = 1.25-5 µg/ml).Formal Name: 2-[1-[4-[2-(4-chlorophenoxy)acetyl]-1-piperazinyl]ethyl]-3-(2-ethoxyphenyl)-4(3H)-quinazolinone.
