An analogue of the bacterial siderophore desferrioxamine B (DFOB) containing a disulfide motif in the backbone was produced from Streptomyces pilosus cultures supplemented with cystamine. Cystamine competed against native 1,5-diaminopentane during assembly. DFOB-(SS)1[001] and its complexes with Fe(iii) or Ga(iii) were cleaved upon incubation with dithiothreitol. Compounds such as DFOB-(SS)1[001] and its thiol-containing cleavage products could expand antibiotic strategies and Au-S-based nanotechnologies.
