General description

Ras-selective lethal small molecule 3 (RSL3) induces ferroptosis by inhibiting the activity of glutathione peroxidase 4 (GPx4). RSL3 not only activates ferroptosis but also blocks the activation of the mammalian target of rapamycin (mTOR) signaling pathway through interactions with GPX4. In thyroid cancer cell lines, RSL3 decreases cell viability, inhibits spheroid formation, and disrupts cell migration in vitro.

Application

1S,3R-RSL 3 has been used:
  • as a glutathione peroxidase 4 (GPX4) inhibitor to study its effects on cell death in subventricular glioblastoma multiforme (GBM) lines
  • GPX4 inhibitor and ferroptosis inducer to study its effects on cardiomyocyte death and heart failure in mice
  • as a ferroptosis inducer in HT-1080 cellsin cell viability assay

We screened small molecules to identify two compounds, which we named RSL3 and RSL5, that have increased lethality in the presence of oncogenic RAS. Counter screening with biologically active compounds defined aspects of the mechanism of action for RSL3 and

In cancer cells the small compounds erastin and RSL3 promote a novel type of cell death called ferroptosis, which requires iron-dependent accumulation of lipid reactive oxygen species. Here we assessed the contribution of lipid peroxidation activity of lipoxygenases (LOX) to
