A series of novobiocin-like coumarincarboxylic acids has been prepared bearing the L-rhamnosyl moiety as the sugar portion of the molecule. The similar DNA gyrase inhibitory activity of the novel class of coumarins to that of novobiocin demonstrates that L-rhamnose can effectively replace L-noviose. Introduction of alkyl side-chains at C-5 of coumarin leads to improved in vitro antibacterial properties
已经制备了一系列带有L-鼠李糖基部分作为分子糖部分的新生物素样香豆素羧酸。新型香豆素对DNA促旋酶的抑制活性与新霉素相似,这表明L-鼠李糖可以有效替代L-鼠新糖。在香豆素的C-5处引入烷基侧链可改善新系列的体外抗菌性能。
