  • Publication number: 20140371491
    Abstract: The present invention implements a strategy that combines an enzyme inhibition assay with a chemical dereplication process to identify active plant extracts and the particular compounds—diarylalkanes and/or diarylalkanols within those extracts that specifically inhibit binuclear enzyme function. Included in the present invention are compositions of matter comprised of one or more of diarylalkanes and/or diarylalkanols, which inhibit the activity of binuclear enzymes, particularly tyrosinase and which prevent melanin overproduction. The present invention also provides a method for inhibiting the activity of a binuclear enzyme, particularly tyrosinase and a method for preventing and treating diseases and conditions related to binuclear enzyme function. The present invention further includes a method for preventing and treating melanin overproduction and diseases and conditions of the skin related thereto.

  • Patent number: 8852657
    Abstract: The identification and isolation of chromones and novel chromone compositions from plant sources that exhibit up-regulation of adiponectin production by adipocytes and the normalization of virtually hundreds of genes related to glucose and fatty acid metabolic and signaling pathways. The chromone compositions are effective in enhancing adiponectin production by adipocytes and regulating genes involved in fatty acid biosynthesis, mitochondrial ?-oxidation of fatty acids, steroid biosynthesis, gluconeogenesis, fat transport, PPAR?/RXR? liver signaling and xenobiotic metabolism. The chromone compositions can be used to increase insulin sensitivity, improve glucose tolerance, lower triglyceride levels and balance glucose levels in mammals. Included are methods for the prevention and treatment of a variety of diseases and conditions including, but not limited to insulin resistance, glucose intolerance, hyperglycemia, metabolic syndromes, dyslipidemia, and hypertriglyceridemia.
