Targeting GPX4 in ferroptosis and cancer: chemical strategies and challenges

Selenoprotein glutathione peroxidase 4 (GPX4) serves as a crucial suppressor of oxidative stress-induced ferroptosis, making it an attractive target for disease therapy. Here, we discuss recent strategies and challenges associated with targeting GPX4 through covalent inhibitors, proteolysis targetin...

Description
Summary:Selenoprotein glutathione peroxidase 4 (GPX4) serves as a crucial suppressor of oxidative stress-induced ferroptosis, making it an attractive target for disease therapy. Here, we discuss recent strategies and challenges associated with targeting GPX4 through covalent inhibitors, proteolysis targeting chimera (PROTAC) degraders, and cell-type-specific degraders in the context of cancer.
