JKE-1674 is an inhibitor of glutathione peroxidase 4 (GPX4) and an active metabolite of the GPX4 inhibitor ML-210. JKE-1674 reduces viability of LOX-IMVI cancer cells and in a panel of additional cancer cell lines, an effect that can be blocked by the ferroptosis inhibitor ferrostatin-1. JKE-1674 forms a nitrile-oxide electrophile in cells. JKE-1674 dehydration yields a nitrile-oxide electrophile that binds GPX4. JKE-1674 exhibits far greater stability than chloroacetamide inhibitors.

| Sulfasalazine
Sulfasalazine is a sulfonamide agent derived from Mesalazine. Sulfasalazine has xC-system inhibitory activity associated with iron death and is primarily used as an anti-inflammatory agent. Sulfasalazine can suppress NF-κB activity. Sulfasalazine is a type 1 ferroptosis inducer. |
| Deferiprone
Deferiprone is the only orally active iron-chelating agent with an affinity for ferric ion (iron III)，binds with ferric ions to form neutral 3:1 (deferiprone:iron) complexes that are stable over a wide range of pH values. |
| Erastin
Erastin is a ferroptosis activator by acting on mitochondrial VDAC, exhibiting selectivity for tumor cells bearing oncogenic RAS. *The compound is unstable in solutions, freshly prepared is recommended |
