* <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 Fer-1 (Ferrostatin-1) is a potent and selective inhibitor of ferroptosis with EC50 of 60 nM.
Targets
Ferroptosis [1]
(HT-1080 cells)
60 nM(EC50)
In vitro

Ferrostatin-1 (2 μM) prevents erastin-induced ferroptosis in cancer cells, as well as glutamate-induced cell death in postnatal rat brain slices. Ferrostatin-1 is a lipid ROS scavenger, with the N-cyclohexyl moiety serving as a lipo-philic anchor within biological membranes. Ferrostatin-1 does not inhibit extracellular signal -regulated kinase (ERK) phos-phorylation or arrest the proliferation of HT-1080 cells, suggesting that it does not inhibit the MEK/ERK pathway, chelate iron, or inhibit protein synthesis. Ferrostatin-1 does, however, prevent erastin-induced accumulation of cytosolic and lipid ROS. Ferrostatin-1 readily oxidizes the stable radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) under cell-free conditions. [1]
In vivo

Ferrostatin-1 (Fer-1), a synthetic antioxidant, is a potent and selective inhibitor of ferroptosis. It acts via a reductive mechanism to prevent damage to membrane lipids and thereby inhibits cell death.[2]
