Mechanism of Action

Targets/IC50/Ki
Ferroptosis
In vitro

Erastin is selectively lethal to oncogenic RAS-mutant cell lines, and triggers a unique iron-dependent form of non-apoptotic cell death called ferroptosis.

This compound binds directly to VDAC2 and causes mitochondrial damage via ROS production in an NADH-dependent manner, which induces cell death in some tumor cells harbouring activating mutations in the RAS-RAF-MEK pathway.

In addition, this chemical, via inducing ROS-mediated CID (Caspase-independent cell death), strongly enhances the effect in WT EGFR cells.

In vivo

Erastin is a ferroptosis activator by inhibiting voltage-dependent anion channels (VDAC2/VDAC3). This compound also inhibits cystine-glutamate antiporter (xCT).
