    摘要: Compounds of the current invention relate to rifamycin derivatives having antimicrobial activities, including activities against drug-resistant microorganisms. More specifically, compounds of the current invention relate to C-25 carbamate derivatives of rifamycin having another functional group or pharmacophore covalently attached to this position through a carbamate linkage. The resulting compounds exert their antimicrobial activity through a dual-function mechanism and therefore exhibit reduced frequency of resistance.

    摘要: 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.
