The first total synthesis of the cyclic depsipeptide natural product teixobactin is described. Synthesis was achieved by solid-phase peptide synthesis, incorporating the unusual l-allo-enduracididine as a suitably protected synthetic cassette and employing a key on-resin esterification and solution-phase macrolactamization. The synthetic natural product was shown to possess potent antibacterial activity
描述了环状二肽天然产物teixobactin的第一个全合成。合成通过固相肽合成来实现,结合有不寻常的升-同种异体-enduracididine为适当保护的合成盒以及采用键树脂上酯化和溶液相macrolactamization。合成的天然产物显示出对多种革兰氏阳性病原菌具有有效的抗菌活性,这些病原菌包括结核分枝杆菌和耐甲氧西林的金黄色葡萄球菌(MRSA)的强毒株。
