The present invention relates to rifamycin 3-iminomethylenyl (-CH=N-) derivatives having antimicrobial activities, including activities against drug-resistant microorganisms. The claimed rifamycin derivative has a rifamycin moiety covalently linked to a linker through an iminomethylenyl (-CH=N-) group at the C-3 carbon of the rifamycin moiety and the linker is, in turn, covalently linked to a quinolone structure or its pharmacophore within the DNA gyrase and topoisomerase IV inhibitor family. The inventive rifamycins are novel and exhibit activity against both rifampin and ciprofloxacin-resistant microorganisms.
本发明涉及具有抗微生物活性的利福霉素3-亚甲基亚胺基(-CH=N-)衍生物,包括对耐药微生物的活性。所述的利福霉素衍生物具有一个利福霉素基团,通过亚甲基亚胺基(-CH=N-)在利福霉素基团的C-3碳上与一个连接剂共价连接,而连接剂又与DNA旋转酶和拓扑异构酶IV抑制剂家族中的奎诺酮结构或其药效团共价连接。这种创新的利福霉素是新颖的,并对利福平和环丙沙星耐药微生物表现出活性。
