chemical structures are rather complex. This study investigated the simplification of these natural products by structure-based drug design, synthesis, and biological evaluation. We developed a simplified rigid scaffold with an arylalkyne moiety, which shows sub-micromolar MraY inhibitory activity. The scaffold is suitable for further investigating the structure–activity relationship by virtue of our

天然产物的简化。我们开发了一种带有芳基炔部分的简化刚性支架,其显示出亚微摩尔MraY抑制活性。该支架适合通过我们的合成策略进一步研究构效关系,其中感兴趣的取代基被安装在合成的最后阶段。该支架显示出进一步用于优化 MraY 抑制和抗菌活性的潜力。
