Page/Page column 59, (2010/02/13)
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.

Compounds of formula (I): STR1 (in which R1 is alkoxy, R is alkyl, haloalkyl, alkylamino, cycloalkyl or optionally substituted phenyl, X is chlorine or fluorine and Y is selected from certain specific heterocycles) have excellent antibacterial activity. They may be prepared by introducing the group represented by Y into the corresponding compound in which Y is replaced by a halogen atom.
