  Practical Synthesis of Hydroxamate-Derived Siderophore Components by an Indirect Oxidation Method and Syntheses of a DIG−Siderophore Conjugate and a Biotin−Siderophore Conjugate

  摘要：

  A practical large-scale synthesis of hydroxamate-derived siderophore components (30 and 40) that utilizes an efficient indirect oxidation method is described and applied to the syntheses of nonradioactive labeled siderophores. Oxidation of imines derived from L-ornithine (17) and its tripeptide (19) afforded oxaziridines that were isomerized to stable-nitrones (16 and 18). Acid-catalyzed hydrolysis of nitrones provided hydroxylamines that were converted to the desired hydroxamic acids (30 and 40) suitable for constructing siderophore-drug conjugates (2). The entire synthetic sequence required no chromatographic separation. DIG- and biotin-labeled ferrichrome analogues designed to detect and isolate ferrichrome receptors in various microbes were also synthesized.

  C-type diazeniumdiolate and N-hydroxypyrrole. Characterizing chalkophomycin biosynthetic enzymes reveals previously unknown enzymes responsible for N-hydroxypyrrole biosynthesis, including the first prolyl-N-hydroxylase, and a key step in the assembly of the diazeniumdiolate-containing amino acid graminine. Discovery of this pathway enriches our understanding of the biosynthetic logic employed in constructing

  AbstractSiderophores are key players in bacteria–host interactions, with the main function to provide soluble iron for their producers. Gramibactin from rhizosphere bacteria expands siderophore function and diversity as it delivers iron to the host plant and features an unusual diazeniumdiolate moiety for iron chelation. By mutational analysis of the grb gene cluster, we identified genes (grbD and grbE) necessary for diazeniumdiolate formation. Genome mining using a GrbD‐based network revealed a broad range of orthologous gene clusters in mainly plant‐associated Burkholderia/Paraburkholderia species. Two new types of diazeniumdiolate siderophores, megapolibactins and plantaribactin were fully characterized. In vitro assays and in vivo monitoring experiments revealed that the iron chelators also liberate nitric oxide (NO) in plant roots. This finding is important since NO donors are considered as biofertilizers that maintain iron homeostasis and increase overall plant fitness.
