ABSTRACT:
Rifamycin derivatives having antimicrobial activities, including activities against drug-resistant microorganisms are claimed in this invention. The inventive rifamycin derivatives are uniquely designed in that they have a rifamycin moiety covalently linked to a linker group through the C-3 carbon of the rifamycin moiety and the linker is, in turn covalently linked to a therapeutic moiety or antibacterial agent/pharmacophore. The therapeutic moiety can be a quinolone, an oxazolidinone, a macrolide, an aminoglycoside, a tetracycline core or a structure/pharmacophore associated with an antibacterial agent.
