The importance of iron chelators in medicine has significantly increased in recent years. Iron is essential for life but it is also potentially more toxic than other trace elements. This is because we lack effective means to protect human cells against iron overload and because of the role of iron in the generation of free radicals. In order to protect patients from the consequences of iron toxicity, iron chelating agents have been introduced in clinical practice. Unfortunately, the ideal chelator for treating iron overload in humans has not been identified yet. In this paper we examine a few characteristics of iron chelators, with some emphasis on the effects of redox cycling, on absorption mechanisms and on some properties of the pFe. A brief summary is then made of the chelators recently proposed or in development for the treatment of iron overload.

Abstract

The importance of iron chelators in medicine has significantly increased in recent years. Iron is essential for life but it is also potentially more toxic than other trace elements. This is because we lack effective means to protect human cells against iron overload and because of the role of iron in the generation of free radicals. In order to protect patients from the consequences of iron toxicity, iron chelating agents have been introduced in clinical practice. Unfortunately, the ideal chelator for treating iron overload in humans has not been identified yet. In this paper we examine a few characteristics of iron chelators, with some emphasis on the effects of redox cycling, on absorption mechanisms and on some properties of the pFe. A brief summary is then made of the chelators recently proposed or in development for the treatment of iron overload.
