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
