Baicalin plays a protective role by regulating ferroptosis in multiple diseases

Ferroptosis is a new kind of cell death discovered in recent years, usually accompanied by a large number of lipid peroxidation and iron accumulation in the process of cell death. Ferroptosis has been proven to play an important role in various diseases, including ischemic reperfusion injury, cancer, and neurodegeneration. Therefore, the regulation of ferroptosis will have a vital impact on the occurrence and development of diseases. Baicalin is a flavonoid compound extracted and isolated from the dried roots of Scutellaria baicalensis Georgi, a plant in the family Lamiaceae. It has various biological activities such as antioxidant, anti-proliferative, anti-inflammatory, anti-thrombotic, and regulates apoptosis and ferroptosis. Recently, increasing evidence indicates that baicalin regulation of ferroptosis is involved in multiple diseases. However, the relevant mechanisms are not yet fully understood. Here, we summarized the role of baicalin regulation of ferroptosis in different kinds of diseases, and conducted an in-depth analysis of the relevant mechanisms, hoping to provide the theoretical references for future related researches.
