Inspired by the core fragment of antibacterial natural products such as streptolydigin, 3‐acyltetramic acids and 3‐acylpiperidine‐2,4‐diones have been synthesised from the core heterocycle by direct acylation with the substituted carboxylic acids using a strategy which permits ready access to a structurally diverse compound library. The antibacterial activity of these systems has been established against
受到抗菌天然产物(例如链霉菌丝蛋白),3-酰基四酸和3-酰基哌啶-2,4-二酮的核心片段的启发,已通过直接与取代的羧酸进行酰化反应从核心杂环合成了一种策略,该策略允许随时使用结构上多样化的化合物库。这些系统的抗菌活性已经针对一系列革兰氏阳性和革兰氏阴性细菌而建立,并且大部分针对前者,在某些情况下非常有效。已获得与针对该文库一小部分的十一碳烯基焦磷酸合酶(UPPS)和/或RNA聚合酶(RNAP)的作用方式一致的数据。活性最高的化合物已显示出在UPPS和RNAP的链霉菌毒素和粘质激肽的已知结合位点上具有结合力。
