ferrostatin-1

Ferrostatin-1 (Fer-1) is a potent and selective inhibitor of ferroptosis. Ferrostatin-1 potently inhibits Erastin-induced ferroptosis in HT-1080 cells with an EC50 of 60 nM. Ferrostatin-1 also exhibits antioxidant and antifungal activities.

SRS16-86 is a novel third-generation ferrostatin, is an inhibitor of ferroptosis.

Erastin2 is an iron death inducer that induces cell death by binding to the lipophilic free radical trapping antioxidant ferrostatin-1 or the iron chelator desferrioxamine (DFO).

SRS11-92 (AA9) is a ferroptosis inhibitor and a derivative of ferrostatin-1

JKE-1716 is an inhibitor of glutathione peroxidase 4 (GPX4) and a derivative of the GPX4 inhibitor ML-210 .1JKE-1716 reduces viability of LOX-IMVI cancer cells in a concentration-dependent manner and in a panel of additional cancer cell lines, an effect that can be blocked by the ferroptosis inhibitor ferrostatin-1 . 1.Eaton, J.K., Furst, L., Ruberto, R.A., et al.Selective covalent targeting of GPX4 using masked nitrile-oxide electrophilesNat.

Ferroptocide, a thioredoxin (Trx) inhibitor and pleuromutilin derivative, exhibits inhibitory activity against Trx in ES-2 ovarian cancer cells at a concentration of 20 µM and demonstrates cytotoxicity towards these cells with an IC50 of 1.6 µM. At a dosage of 5 µM, it induces ferroptosis in ES-2 cells, which is mitigatable by the iron chelator deferoxamine (DFO), the antioxidant Trolox, or the ferroptosis inhibitor ferrostatin-1. Furthermore, it effectively reduces tumor volume in a 4T1 murine mammary carcinoma model with immunocompetent mice, but not in immunodeficient mice, when administered at 50 mg/kg bi-weekly.
