  • Patent number: 6277985
    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.

  • Patent number: 6265178
    Abstract: Anti-microbial oxazolidinone antibiotics are provided having formula I and formula II wherein R1 is methyl, ethyl, cyclopropyl, or dichloromethyl; R2 and R3 are independently hydrogen or fluoro; R4 is ethyl or dichloromethyl. The oxazolidinone antibiotics have minimum inhibitory activity for monoamine oxidase. An assay for detecting such oxazolidinone antibiotics is carried out by incubating a potential oxazolidinone inhibitor with a monoamine oxidase, then adding 1-methyl-4-(1-methyl-2-pyrryl)-1,2,3,6-tetrahydropyridine and determining inhibitory activity of the antibiotic.
