Compounds according to formula I are provided: A-L-B wherein A represents a lipophilic chelating moiety which is selective for Zn
2+
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. A method of treating and/or preventing a bacterial infection in a human or non-human mammal employing such compounds are also provided. In such a method, the compound of formula I may be administered in combination with (either simultaneously, separately, or sequentially) a β-lactam antibiotic.
提供符合公式I的化合物:A-L-B,其中A代表亲脂性螯合基团,该基团选择性地与Zn2+离子结合;L是共价键或连接剂;B是载体,可以是与细菌中的一个或多个
生物结构相互作用的基团(优选在细菌细胞壁中),例如与
金属β-内酰胺酶或DD转移酶等
青霉素结合蛋白相互作用的基团,或者是增强化合物穿过细菌细胞膜的基团。还提供了一种使用这些化合物治疗和/或预防人类或非人哺乳动物细菌感染的方法。在这种方法中,公式I的化合物可以与β-内酰胺类抗生素(同时、分别或顺序)联合使用。
