Baicalin interferes with iron accumulation in C6 glioma cells

摘要： Baicalin reacts with ferric ammonium citrate and acts as an-iron chelator.The maximal reaction time for baicalin to interact with irons was approximately 3 hours.C6 glioma cell survival decreased following iron-loading,with a large number of cells accumulating iron.In addition,lipid peroxidation increased.Iron accumulation and lipid peroxidation were the major cause of cellular death.Baicalin and ferric ammonium citrate alleviated iron accumulation in C6 cells and lowered the mortality of nerve cells.In addition,malondialdehyde and lactate dehydrogenase levels reduced.These results indicate that baicalin strongly inhibits lipid peroxidation via chelation,reduces the content of iron in C6 cells,lowers lipid peroxidation,and thus plays a protective role against iron-induced nerve cell death. （共5頁）
