  • Patent number: 7884099
    Abstract: The compounds include substituted rifamycin derivatives in which a quinolone carboxylic acid pharmacophore is covalently bonded to a benzoxazinorifamycin or a spiropiperidinorifamycin. The rifamycin derivatives are useful as antimicrobial agents and are effective against a number of human and veterinary Gram positive and Gram negative pathogens. The advantage of the inventive compounds is that both the rifamycin and quinolone antibacterial pharmacophores are co-delivered with matched pharmacokinetics to the targeted pathogens of interests. Delivery of multiple antibacterial pharmacophores simultaneously to the targeted pathogens has the maximum chance of achieving synergy and minimizing the development of resistance to the antibiotics given.

  • Patent number: 7666864
    Abstract: The current invention provides a series of bicyclic nitroimidazole-substituted phenyl oxazolidinones in which a bicyclic nitroimidazole pharmacophore is covalently bonded to a phenyl oxazolidinone, their pharmaceutical compositions, and the method of use of the compositions for prevention and treatment of bacterial infections. The bicyclic nitroimidazole-substituted phenyl oxazolidinones possess surprising antibacterial activity against wild-type and resistant strains of pathogens, and are therefore useful for the prevention, control and treatment of a number of human and veterinary bacterial infections caused by these pathogens, such as Mycobacterium tuberculosis.

  • Patent number: 7247634
    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.

  • Patent number: 7238694
    Abstract: 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.
