  • Patent number: 7211598
    Abstract: The invention describes novel cyclooxygenase 2 (COX-2) selective inhibitors having at least one oxime group or hydrazone group and novel compositions comprising at least one cyclooxygenase 2 (COX-2) selective inhibitor having at least one oxime group or hydrazone group, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or at least one therapeutic agent. The invention also provides novel kits comprising at least one COX-2 selective inhibitor having at least one oxime group or hydrazone group, optionally nitrosated and/or nitrosylated, and, optionally, at least one nitric oxide donor, and/or, optionally, at least one therapeutic agent. The novel cyclooxygenase 2 selective inhibitors of the invention having at least one oxime group or hydrazone group can be optionally nitrosated and/or nitrosylated.

    Abstract: The invention describes novel nitrosated nonsteroidal antiinflammatory drugs (NSAIDs) and pharmaceutically acceptable salts thereof, and novel compositions comprising at least one nitrosated NSAID, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or at least one therapeutic agent. The invention also provides novel compositions comprising at least one nitrosated NSAID, and at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one therapeutic agent. The invention also provides novel kits comprising at least one nitrosated NSAID, and, optionally, at least one nitric oxide donor and/or at least one therapeutic agent.

  • Publication number: 20040162243
    Abstract: The invention describes compositions and kits comprising 4-aza-4-(2-methyl-2-sulfanylpropyl)tricyclo(5.2.1.0<2,6>)dec-8-ene-3,5-dione; 4-aza-4-(2-methyl-2-(nitrosothio)propyl)tricyclo(5.2.1.0<2,6>)dec-8-ene-3,5-dione; 4-{1-methyl-1-((2,4,6-trimethoxyphenyl)methylthio)ethyl}-1,3-oxazolidin-2-one; 2-aAmino-3-methyl-3-((2,4,6-trimethoxyphenyl)methylthio)butan-1-ol; 4-(1-methyl-1-(nitrosothio)ethyl)-1,3-oxazolidin-2-one; or pharmaceutically acceptable salts thereof. The compositions of the invention can further comprise at least one penetration enhancer, at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one vasoactive agent.
