Hazard Information | Back Directory | [Description]
Erastin, named for eradicator of RAS and small T (ST) antigen-expressing cells, is a ferroptosis inducer.1 It induces ferroptotic cell death in vitro, an effect that can be blocked by the ferroptosis inhibitors ciclopirox olamine, Trolox (Item No. 10011659), ferrostatin-1 (Item No. 17729), U-0126 (Item No. 70970), cycloheximide (Item No. 14126), 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).2 | [Uses]
Erastin, 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] | [Definition]
ChEBI:Erastin is a member of the class of quinazolines that is quinazolin-4(3H)-one in which the hydrogens at positions 2 and 3 are replaced by 1-{4-[(4-chlorophenoxy)acetyl]piperazin-1-yl}ethyl and 2-ethoxyphenyl groups, respectively. It is an inhibitor of voltage-dependent anion-selective channels (VDAC2 and VDAC3) and a potent ferroptosis inducer. It has a role as a ferroptosis inducer, an antineoplastic agent and a voltage-dependent anion channel inhibitor. It is a member of quinazolines, a member of monochlorobenzenes, an aromatic ether, a N-acylpiperazine, a N-alkylpiperazine, a diether and a tertiary carboxamide. | [General Description]
Erastin is a cell-permeable piperazinyl-quinazolinone. It interacts with antiporter system Xc-. | [Biochem/physiol Actions]
Erastin is an antitumor agent selective for tumor cells bearing oncogenic RAS (i.e. HRAS, KRAS). Erastin produces ferroptosis, a non-apoptotic tumor cell death, by altering mitochondrial voltage-dependent anion channel (VDAC) gating allowing cations to enter mitochondria and leading to release of oxidative species causing oxidative cell death. | [storage]
Store at -20° C, unstable in solution, ready to use. | [References]
