  • Patent number: 6916843
    Abstract: Epoxyeicosatrienoic acids (EETs) are products of cytocrome P450 epoxygenases that have vasodilatory properties similar to endotheilum-derived hyperpolarizing factor (EDHF). The cytochrome P450 isoform CYP2J2 was cloned and identified as a source of EETs in human endothelial cells. Physiological concentrations of EETs or overexpression of CYP2J2 decreased cytolcine-induced endothelial cell adhesion molecule expression and prevented subsequent leukocyte adhesion to the vascular wall by a mechanism involving inhibition of transcription factor NF-?B and I?B kinase (IKK). The inhibitory effects of EETs were independent of their membrane hyporpolarizing effects suggesting that these molecules play an important non-vasodilatory role in vascular inflammation.

  • Patent number: 6818669
    Abstract: A method and compositions are provided for increased cerebral bioavailability of blood-born compositions by administering the composition of interest while increasing brain NO levels. This increase in NO levels may be accomplished by stimulating increased production of NO by eNOS, especially by administering L-arginine, by administering agents that increase NO levels independent of ecNOS, or by any combination of these methods. As NO is increased, cerebral blood flow is consequently increased, and drugs in the blood stream are carried along with the increased flow into brain tissue. By increased flow, the site of action will be exposed to more drug molecules. By stimulating increased NO production, administration of drugs that are not easily introduced to the brain may be facilitated and/or the serum concentration necessary to achieve desired physiologic effects may be reduced.

  • Patent number: 6696480
    Abstract: A use for agents that disrupt actin cytoskeletal organization is provided. In the instant invention, agents that disrupt actin cytoskeletal organization are found to upregulate endothelial cell Nitric Oxide Synthase activity. As a result, agents that disrupt actin cytoskeletal organization are useful in treating or preventing conditions that result from the abnormally low expression and/or activity of endothelial cell Nitric Oxide Synthase. Such conditions include hypoxia-induced conditions. Subjects thought to benefit mostly from such treatments include nonhyperlipidemics and nonhypercholesterolemics, but not necessarily exclude hyperlipidemics and hypercholesterolemics.

  • Patent number: 6566081
    Abstract: This invention provides new methods and compounds for controlling the intracellular and physiological effects of steroid hormones, including but not limited to estrogen, through modulation of the interaction of such hormone receptors with phosphatidylinositol-3 kinase. Compounds and methods for controlling the activation of endotbelial nitric oxide synthase are also disclosed.
