Siderophores are small molecules that are produced and secreted by micro-organisms in order to mediate the uptake of essential Fe(III) into the cell. This chapter provides a concise overview of siderophores, their chemistry and importance in nature, synthetic siderophore mimics, derivatives and their applications. Since the competition for Fe(III) requires micro-organisms to continuously evolve their uptake pathways, new siderophores are continually being discovered. A description of the chemical design features of siderophores and their coordination chemistry is followed by examples chosen to illustrate their chemical synthesis and biosynthesis. Recent insights into siderophore-mediated iron uptake and the proteins involved in the process are summarized for both Gram-negative and Gram-positive bacteria. It is then illustrated how high-affinity Fe(III)-chelators can be exploited in the design of Trojan horse antibiotics, the treatment of iron overload and the development fluorescent chemosensors.
