Molecular Weight 340.85 CAS No. 950455-15-9
Solubility (25°C)* In vitro DMSO 68 mg/mL (199.5 mM)
Ethanol 34 mg/mL (99.75 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
2%DMSO 40%PEG300 2%Tween80 56%ddH2O
3.0mg/ml Taking the 1 mL working solution as an example, add 20 μL of 150 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 20 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 560 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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.
