RSL3
a selective GPx4 inhibitor, mediates concentration-dependent inhibition of GPX4, lipid peroxidation, enhanced mitochondrial fragmentation, loss of mitochondrial membrane potential, and reduced mitochondrial respiration. Ferroptosis inhibitors, such as deferoxamine, ferrostatin-1 and liproxstatin-1, but also CRISPR/Cas9 Bid knockout and the BID inhibitor BI-6c9 protect against RSL3 toxicity.
