Abstract

A dozen oxime, hydrazine and hydrazide derivatives of platensimycin (PTM) analogues were synthesized, some of which showed strong antibacterial activities and were shown to be stable under the bioassay conditions. Docking analysis revealed that they have certain new interactions with β-ketoacyl-[acyl carrier protein] synthase II (FabF), suggesting that Schiff base formation on its terpene scaffold is an effective strategy to diversify PTM structure.

摘要

合成了十二种扁枝衣霉素(PTM)类似物的肟、肼和酰肼衍生物,其中一些表现出较强的抗菌活性,并且在生物测定条件下显示稳定。对接分析表明,它们与β-酮酰基-[酰基载体蛋白]合酶II(FabF)有某些新的相互作用,这表明在其萜烯支架上形成席夫碱是使PTM结构多样化的有效策略。
