    摘要: Novel rifamycin derivatives of formula I (both hydroquinone and corresponding quinone (C1-C4) forms): or their salts, hydrates or prodrugs thereof, wherein: a preferred R comprises hydrogen, acetyl; L is a linker, a preferred linker group elements selected from any combination of 1 to 5 groups shown FIG. 1, provided L is not wherein R1 is H, methyl or alkyl. The inventive compounds exhibit valuable antibiotic properties. Formulations having these compounds can be used in the control or prevention of infectious diseases in mammals, both humans and non-humans. In particular, the compounds exhibit a pronounced antibacterial activity, even against multiresistant strains of microbes.

    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.
