Biological Activity

Description Liproxstatin-1 is a potent ferroptosis inhibitor with an IC50 of 22 nM.
Targets
ferroptosis [1]
(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. Liproxstatin-1 (50 nM) completely prevents lipid peroxidation in Gpx4−/−cells. Liproxstatin-1 (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).[1]
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. [1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    Gpx4−/−cells

  • Concentrations

    ~200 nM

  • Incubation Time

    ~72 h

  • Method

    Cell viability is assessed at different time points after treatment using AquaBluer according to the manufacturer’s recommendations. Alternatively, cell death is also quantified by measuring released lactate dehydrogenase activity using the cytotoxicity detection kit (LDH).
Animal Study:

[1]
  • Animal Models

    GreERT2; Gpx4fI/fI mice

  • Dosages

    10 mg/kg

  • Administration

    i.p.
