  Total Synthesis of the Siderophore Danoxamine

  摘要：

  The total synthesis of the linear trihydroxamate siderophore, Danoxamine, is described. Danoxamine is a siderophore component of the naturally occurring siderophore-drug conjugates Salmycin A-D. The synthesis of Danoxamine features a series of coupling reactions involving N-(5-benzyloxypentyl)-O-benzylhydroxylamine being linked by a succinoyl linker to N-(benzyloxy)-1,5-pentanediamine. Two more succinoyl linkers and another N-(benzyloxy)-1,5-pentanediamine were used in coupling reactions to afford the fully protected siderophore. The linear tetrabenzyl-protected trihydroxamate was deprotected to afford the natural product Danoxamine.

  New synthetic routes were devised for total synthesis of Fe3+-bound (ferri−) salmycin B (Sal B) (1), glycan-based Sal analogues 2–5 and their Fe3+-unbound (desferri−) counterparts 1′–5′ for the structure to activity relationship (SAR) study. The results of SAR study reveal the effective structure of 1 and its desferri-counterpart 1′ that are responsible for the observed inhibitory activity against

  设计了新的合成路线，用于全合成 Fe 3+结合 ( ferri −) 沙霉素 B (Sal B) ( 1 )、基于聚糖的 Sal 类似物2 – 5及其 Fe 3+未结合 ( desferri −) 对应物1′ – 5'用于结构与活性关系（SAR）研究。SAR 研究结果揭示了1及其去铁蛋白对应物1'的有效结构，它们负责观察到的对金黄色葡萄球菌( S. aureus ) 的抑制活性。在类似物2 – 5和2′ – 5′中，基于葡萄糖的类似物2及其去铁对应物2′表现出与1和1′相当的抑制效力。通过对2′进行化学修饰，进一步进行抗菌研究，我们发现了desferri -Sal类似物7′，它具有更简单的药效团结构，但对甲氧西林敏感和耐药的金黄色葡萄球菌的抗菌效力明显高于天然产物1′，甚至临床上也有显着提高。万古霉素。类似物7'具有更好的水解稳定性和更短的合成路线，是一种值得进一步探索的有吸引力的抗生素先导化合物。
