Mechanism of Action

Targets/IC₅₀/Ki	ferroptosis (Cell-free assay) 22 nM
In vitro	Liproxstatin-1 is able to inhibit ferroptosis in the low nanomolar range and inhibit the growth of Gpx4^−/−cells with IC50 of 22 nM. This compound (50 nM) completely prevents lipid peroxidation in Gpx4^−/−cells. It (200 nM) protects against FINs, such as BSO (10 µM), erastin (1 µM) and RSL3 (0.5 µM), in a dose dependent manner, whereas it fails to rescue cell death induced by staurosporine (0.2 µM) and H₂O₂ (200 µM).
In vivo	Liproxstatin-1 remarkably extends survival compared with the vehicle-treated group, delays Ferroptosis in tubular cells, and mitigates tissue injury in ischaemia/reperfusion-induced liver injury.
