ferrostatin-1

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

Ferrostatin-1 diyne (Fer-1 diyne) (compound 2) serves as an inhibitor of ferroptosis, accumulating in cellular lysosomes, mitochondria, and the endoplasmic reticulum. It notably inhibits ferroptosis independently of lysosomal and mitochondrial activity.

NYY-6a is a ferroptosis (Ferroptosis) inhibitor, demonstrating significant suppression of RSL3-induced ferroptosis in 786-O and HT-1080 cells, with EC50 values of 52 nM and 50 nM, respectively. As a radical-trapping antioxidant (RTA), NYY-6a effectively reduces lipid peroxidation, comparable to ferrostatin-1 and liproxstatin-1, making it useful for research into ferroptosis-related pathologies.

GPX4 9i is a ferroptosis inducer that exhibits cytotoxicity towards HT-1080 cells, with an IC50 of 0.007 µM. This cytotoxic effect can be mitigated by the use of the ferroptosis inhibitor, ferrostatin-1.

Erastin2 is a ferroptosis inducer and inhibitor of the system xc- cystine/glutamate transporter.[1][2] It inhibits glutamate release in CCF-STTG1 cells (IC50 = 0.0035 µM) and induces cell death in HAP1 cells at 5 µM, an effect blocked by ferrostatin-1 or deferoxamine.[1][2] Erastin2 also induces ferroptotic cell death in HT-1080 cells (EC50 = 0.15 µM), an effect blocked by β-mercaptoethanol (EC50 > 20 µM).[3] Additionally, it increases lipid peroxidation in HT-1080 cells at 1 µM.

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.

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

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