Ferroptosis Inhibitors Small Molecules and Peptides

Ferroptosis is a form of regulated cell death, distinct from apoptosis, necroptosis and autophagy. It is an iron-dependent process that results from the loss of glutathione peroxidase 4 (GPX4) activity, leading to accumulation of lipid peroxidation products and reactive oxygen species (ROS).

GPX4 is a selenoprotein that reduces hydrogen peroxide and lipid peroxides, while converting reduced glutathione (GSH) to its oxidized form; oxidized glutathione (glutathione disulfide) is recycled by ...
