The bacterial cell division protein FtsZ is one of many potential targets for the development of novel antibiotics. Recently, zantrin Z3 was shown to be a cross-species inhibitor of FtsZ; however, its specific interactions with the protein are still unknown. Herein we report the synthesis of analogues that contain a more tractable core structure and an analogue with single-digit micromolar inhibition
细菌细胞分裂蛋白 FtsZ 是开发新型抗生素的众多潜在目标之一。最近,zantrin Z3 被证明是 FtsZ 的跨物种抑制剂;然而,它与蛋白质的特定相互作用仍然未知。在此,我们报告了包含更易处理的核心结构的类似物的合成,以及对 FtsZ 的 GTPase 活性具有个位数微摩尔抑制的类似物,这是迄今为止报道的最有效的大肠杆菌FtsZ抑制剂。此外,zantrin Z3 核心已转化为两种潜在的光交联试剂,用于蛋白质组学研究,可以阐明 FtsZ 与与 zantrin Z3 相关的分子之间的分子相互作用。
