antibacterial compounds. We report here the inhibition of MurA by natural products from tulips (tulipalines and tuliposides), and the structure–activity relationships of various derivatives. The inhibition of MurA can be related to antibacterial activity, and MurA is probably one of the relevant molecular targets of the tulipaline derivatives. MurA inhibition by this class of compounds depends on the
MurA酶在肽聚糖生物合成中执行必不可少的步骤,因此是发现新型抗菌化合物的目标。我们在这里报告了来自郁金香(郁金香油和tuliposides)的天然产物对MurA的抑制作用,以及各种衍生物的结构-活性关系。MurA的抑制作用可能与抗菌活性有关,MurA可能是郁金香油碱衍生物的相关分子靶标之一。这类化合物对MurA的抑制作用取决于底物UNAG的存在,如先前对烟碱所观察到的,这表明存在非共价自杀抑制作用。但是,就选择性而言,在当前数据集中,尚未将对任意巯基(例如在谷胱甘肽中)的反应性与MurA抑制作用充分分离。
