Description
ML210 (CAS 1360705-96-9) is selectively synthetic lethal to HRAS expressing cells compared to isogenic non-HRAS cells (IC50?= 7.1 nM for BJeLR (expressing HRASg12v) cells vs IC50?= 272 nM for BJeH-LT (non-HRAS expressing) cells.1?ML210 is able to inhibit glutathione peroxidase 4 (GPX4), an important selenoenzyme that protects cells from ferroptosis caused by iron catalyzed formation of free radicals from lipid peroxides.2,3?Treatment of several treatment-resistant cancer cell lines exhibiting a high mesenchymal state with ML210 resulted in selective induction of ferroptosis.3
Uses
ML 210 has been used as a glutathione peroxidase 4 (GPX4) inhibitor to induce ferroptosis in cancer cells. It has also been used as a GPX4 inhibitor to examine whether pharmacological inhibition of GPX4 altered prominin2 expression and impacted ferroptosis in adherent MCF10A and Hs578t cells.
Biochem/physiol Actions
ML 210 induces non-apoptotic cell death in tumor cells expressing the RAS oncogene.
