Abstract

Siderophores based on sugar backbones substituted at the 2,3,4- or 2,3,6 positions with hydroxamic or retro-hydroxamic acid chelating units were synthesized and characterized. The alkyl terminus of the iron-coordinating side chain units facilitate lipophilic interactions. Iron coordination properties and complex stability were investigated by ESI-MS and the CAS-Test. The results were correlated to structure activity relationships determined by microbial growth promotion studies under iron limited conditions using wild type strains and iron transport mutants of Mycobacterium smegmatis.
