FPH1, also known as BRD-6125, is primarily utilized in the field of biomedical research, particularly in the study of cellular processes and disease mechanisms. It serves as a potent and selective inhibitor of ferroptosis, a form of regulated cell death driven by iron-dependent lipid peroxidation. Researchers employ FPH1 to investigate the role of ferroptosis in various pathological conditions, including neurodegenerative diseases, cancer, and ischemia-reperfusion injury. By modulating ferroptosis, FPH1 helps in understanding the underlying molecular pathways and identifying potential therapeutic targets. Additionally, it is used in experimental models to explore the protective effects against oxidative stress and cell death, contributing to the development of novel treatment strategies for diseases associated with ferroptotic cell death.
