  • Patent number: 6525193
    Abstract: The present invention provides for aminoaryl oxazolidinone N-oxide compounds of Formula I wherein the variables are as defined herein. These compounds are exceedingly water soluble which is useful in preparing pharmaceutical formulations of these compounds. They are also rapidly converted back to the parent amines in vivo, making them useful as prodrugs of the parent amines. They are effective against a number of human and veterinary pathogens, including gram-positive aerobic bacteria such as multiply-resistant staphylococci, streptococci and enterococci as well as anaerobic organisms, such as Bacteroides spp. and Clostridia spp. species, and acid-fast organisms such as Mycobacterium tuberculosis, Mycobacterium avium and Mycobacterium spp., and in organisms such as Mycoplasma spp.
