ERASTIN

BeschreibungErastin, 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 , ferrostatin-1 , U-0126 , cycloheximide , and β-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).

VerwendenErastin, named for eradicator of RAS and ST-expressing cells, is an irreversible antitumor agent that selectively kills cells expressing the small T oncoprotein and oncogenic Ras (IC50s = 1.25-5 μg/ml). It produces non-apoptotic tumor cell death by altering mitochondrial voltage-dependent anion channel gating, allowing cations to enter mitochondria and leading to release of oxidative species causing oxidative cell death.[Cayman Chemical]
