The invention provides compounds according to formula I: A - L - B wherein A represents a lipophilic chelating moiety which is selective for Zn2+ ions; L is a covalent bond or a linker; and B is a vector which is either a moiety capable of interacting with one or more biological structures found in a bacterium (preferably in a bacterial cell wall), for example a penicillin-binding protein such as a metallo-β- lactamase or DD-transferase, or a moiety capable of enhancing transport of the compound across a bacterial cell membrane. Such compounds find use in a method of treating and/or preventing a bacterial infection in a human or non-human mammal. In such a method, the compound of formula I may be administered in combination with (either simultaneously, separately, or sequentially) a β-lactam antibiotic.
该发明提供了符合以下公式I的化合物:A - L - B,其中A代表选择性对Zn2+离子的亲脂螯合基团;L是共价键或连接物;B是矢量,可以是能与细菌中的一个或多个
生物结构相互作用的基团(最好是在细菌细胞壁中找到的),例如
金黄色葡萄球菌结合蛋白(例如
金属β-内酰胺酶或DD-转移酶),或者是能增强化合物穿过细菌细胞膜的基团。这种化合物可用于治疗和/或预防人类或非人哺乳动物的细菌感染的方法。在这种方法中,公式I的化合物可以与(同时、分开或顺序地)β-内酰胺类抗生素一起给予。
