Abstract
Siderophore natural products are characterized by an ability to tightly chelate metals. The origins of such compounds are often pathogenic microbes utilizing siderophores as virulence factors during host infection. The mechanism for siderophore formation typically involves the activity of nonribosomal peptide synthetases producing compounds across functional group classifications that include catecholate, phenolate, hydroxamate, and mixed categories. Though siderophore production has been a hallmark of pathogenicity, the evolutionarily-optimized binding abilities of siderophores suggest the possibility of re-directing the compounds towards alternative beneficial applications. In this mini-review, we will first describe siderophore formation origins before discussing alternative applications as pharmaceutical products. In so doing, we will cover examples and applications that include reducing metal overload, targeted antibiotic delivery, cancer treatment, vaccine development, and diagnostics. Included in this analysis will be a discussion on the native production hosts of siderophores and prospects for improvement in compound access through the adoption of heterologous biosynthesis.

Evaluation of a reducible disulfide linker for siderophore-mediated delivery of antibiotics. J Biol Inorg Chem 2018; 23:1025-1036.

Abstract
Bacterial iron uptake machinery can be hijacked for the targeted delivery of antibiotics into pathogens by attaching antibiotics to siderophores, iron chelators that are employed by bacteria to obtain this essential nutrient. We synthesized and evaluated Ent-SS-Cipro, a siderophore-antibiotic conjugate comprised of the triscatecholate siderophore enterobactin and the fluoroquinolone antibiotic ciprofloxacin that contains a self-immolative disulfide linker. This linker is designed to be cleaved after uptake into the reducing environment of the bacterial cytoplasm. We show that the disulfide bond of Ent-SS-Cipro is cleaved by reducing agents, including the cellular reductant glutathione, which results in release of the unmodified fluoroquinolone antibiotic. Antibacterial activity assays against a panel of Escherichia coli show that Ent-SS-Cipro exhibits activity against some, but not all, E. coli. This work informs the design of siderophore-antibiotic conjugates, particularly those carrying antibiotics with cytoplasmic targets that require release after uptake into bacterial cells, and indicates that disulfide linkers may not be generally applicable for conjugation strategies of antibiotics.

Abstract
Desferrioxamine B (DFOB) was discovered in the late 1950s as a hydroxamic acid metabolite of the soil bacterium Streptomyces pilosus. The exquisite affinity of DFOB for Fe(III) identified its potential for removing excess iron from patients with transfusion-dependent hemoglobin disorders. Many studies have used semisynthetic chemistry to produce DFOB adducts with new properties and broad-ranging functions. More recent approaches in chemical biology have revealed some nuances of DFOB biosynthesis and discovered new DFOB-derived drugs and radiometal imaging agents. The current and potential applications of DFOB continue to inspire a rich body of chemical biology research focused on this bacterial metabolite.

Abstract
A novel theranostic prodrug was designed and synthesized by conjugating a naphthalimide derivative with vitamin D2via a disulfide linker. The prodrug featured a highly selective detection process for glutathione (GSH) and showed a red-shifted fluorescence within 30 min. Notably, it also exhibited antitumor activity similar to vitamin D2 and could be monitored by cellular imaging. A novel glutathione-triggered theranostic prodrug was synthesized by conjugating the naphthalimide chromophore and vitamin D2via a disulfide bond.![]()

Abstract
Siderophores are small molecules used to specifically transport iron into bacteria via related receptors. By adapting siderophores and hijacking their pathways, we may discover an efficient and selective way to target microbes. Herein, we report the synthesis of a siderophore-fluorophore conjugate VF-FL derived from vibrioferrin (VF). Using flow cytometry and fluorescence microscopy, the probe selectively labeled vibrios, including V. parahaemolyticus, V. cholerae, and V. vulnificus, even in the presence of other species such as S. aureus and E. coli. The labeling is siderophore-related and both iron-limited conditions and the siderophore moiety are required. The competitive relationship between VF-FL and VF in vibrios implies an unreported VF-related transport mechanism in V. cholerae and V. vulnificus. These studies demonstrate that the siderophore scaffold provides a method to selectively target microbes expressing cognate receptors under iron-limited conditions.
