Research progress on the use of traditional Chinese medicine to treat diseases by regulating ferroptosis.

Ferroptosis is an emerging form of programmed cell death triggered by iron-dependent lipid peroxidation. It is distinguished from other forms of cell death by its unique morphological changes and characteristic fine-tuned regulatory gene network. Since its pivotal involvement in the pathogenesis and therapeutic interventions of various diseases, such as malignant tumors, cardiovascular and cerebrovascular diseases, and traumatic disorders, has been well-established, ferroptosis has garnered significant attention in contemporary physiological and pathological research. For the advantage of alleviating the clinical symptoms and improving life quality, traditional Chinese medicine (TCM) holds a significant position in the treatment of these ailments. Moreover, increasing studies revealed that TCM compounds and monomers showed evident therapeutic efficacy by regulating ferroptosis via signaling pathways that tightly regulate redox reactions, iron ion homeostasis, lipid peroxidation, and glutathione metabolism. In this paper, we summarized the current knowledge of TCM compounds and monomers in regulating ferroptosis, aiming to provide a comprehensive review of disease management by TCM decoction, Chinese patent medicine, and natural products deriving from TCM through ferroptosis modulation. The formulation composition, chemical structure, and possible targets or mechanisms presented here offer valuable insights into the advancement of TCM exploration.
