  • Patent number: 6747063
    Abstract: In the field of treatment of erectile dysfunction there is disclosed a novel therapy in which the actions of an agent or agents, produce a combination of effects to induce effective erection (and avoid priapism) while reducing or entirely avoiding pain. The method taught combines a first action of an agent which is to antagonize a drug-induced pain stimulus within nociceptive nerves of penile tissue with a second action of either the same agent or of a second agent, which enhances, synergistically, smooth muscle relaxation. The synergism allows for at least an equivalent effect of smooth muscle relaxation to be obtained at significantly lower doses of a smooth muscle relaxing agent such as PGE1 which in standard therapy is also in 40-45% of cases pain-inducing at doses which achieve effective erection.

  • Patent number: 6569902
    Abstract: PBN (&agr;-phenyl-tert-butylnitrone), and its derivatives nitrone-based free radical traps, significantly reduce preneoplastic nodule development as well as inhibit hepatocellular carcinoma (HCC) formation at very low levels. The involvement of reactive oxygen species (ROS) in cancer development has been strongly implicated for many years. The involvement of ROS has been strongly implicated in cancer development is a model system where feeding a choline deficiency (CD) diet to rats leads to hepatocellular carcinoma (HCC) development. Administering PBN in the drinking water inhibits HCC formation. Preneoplastic nodule growth in the liver is significantly suppressed by administering PBN, or some of its natural metabolites, in the diet. The effectiveness of PBN in preventing HCC development in the CD liver model is considered due to its prevention of tumor development after the target cells have already been initiated, i.e. genetically changed into tumor cells.

  • Publication number: 20030078241
    Abstract: A method of treatment is disclosed whereby a nitroxide compound is administered to a patient in a therapeutically effective amount. The nitroxide compound is comprised of a first portion which comprises a nitrogen atom and an oxygen atom bound directly together and an unpaired electron (.NO), and a second portion which provides a negative charge. The first and second portions are connected directly or indirectly by a linking group positioned between and bound to the first portion and the second portion in a manner such that the negative charge of the second portion stabilizes the .NO of the first portion when the nitroxide is present in the patient. By stabilizing the .NO portion of the molecule the nitroxide is allowed to interact with reactive oxygen species in the patient for a longer period of time and modulate adverse effects of those reactive oxygen species.

    Abstract: In the field of treatment of erectile dysfunction there is disclosed a novel therapy in which the actions of an agent or agents, produce a combination of effects to induce effective erection (and avoid priapism) while reducing or entirely avoiding pain. The method taught combines a first action of an agent which is to antagonize a drug-induced pain stimulus within nociceptive nerves of penile tissue with a second action of either the same agent or of a second agent, which enhances, synergistically, smooth muscle relaxation. The synergism allows for at least an equivalent effect of smooth muscle relaxation to be obtained at significantly lower doses of a smooth muscle relaxing agent such as PGE1 which in standard therapy is also in 40-45% of cases pain-inducing at doses which achieve effective erection.

  • Patent number: 6287601
    Abstract: Compositions and methods of the topical treatment of equine laminitis are disclosed. In particular, combinations of a fast acting nitric oxide (NO) donor, a sustained acting NO donor and an NSAID mixed in a lipid-based carrier are described. The application of such combinations to the affected areas, e.g., the hoofs and surrounding tissues, of an equine afflicted with laminitis provides relief from the debilitating effects of this painful, often life-threatening condition.

  • Patent number: 6197825
    Abstract: The present invention relates to chromotropic nitrone spin trapping agents, methods of making these agents, compositions comprising same, and methods of their use. In particular, azulenyl nitrones of the present invention are effective agents for trapping free radical species and find use as efficient antioxidants in physicochemical and biological systems. Accordingly, the invention also relates to spin adducts formed from the combination of azulenyl nitrones with free radicals. The compounds of the present invention are readily prepared from available starting materials and find further use in assays and in a number of diagnostic, prophylactic and therapeutic applications, including but not limited to the alleviation, modulation and inhibition of the negative effects of carbon-centered or oxygen-centered radical species and other products of oxidation. Moreover, the combination adducts may be calorimetrically detected and, optionally, isolated and characterized to obtain valuable information (e.g.
