WebAug 21, 2024 · The pathway can be triggered by multiple mechanisms that modulate intracellular glutathione (GSH) pool, labile iron levels, polyunsaturated fatty acids (PUFAs), and the activity of GSH peroxidase 4 (GPX4), a selenoprotein that reduces phospholipid hydroperoxides using GSH and prevents ferroptotic cell death ( 13 – 15 ). The production and oxidation process of GSH has multiple links that can be regulated (Fig. 3). RSL3 was discovered together with RSL5, though they function differently. RSL3 targets enzymes with nucleophilic active sites, acting on GPX4 to induce ferroptosis [37]. Other compounds, such as ML162, DPI7 and … See more Erastin, as mentioned above, was first discovered in 2003 as a genotype-selective antitumor agent.
