Antioxidant and radical scavenging activity of synthetic analogs of desferrithiocin

Free radicals and reactive oxygen species have the potential to damage a wide variety of organic molecules, typically by oxidizing certain moieties. These damaging species can, for example, be produced by an organism as a by-product of cellular respiratio
