  • Patent number: 8357786
    Abstract: Disclosed is an AMPK activating material used for improving and treating metabolic syndrome, in which AMPK (AMP-activated protein kinase) is a main enzyme for regulating an energy sensor and lipid/glucose metabolism in the body. The activation of AMPK inhibits the synthesis of fat and cholesterol, and accelerates the reduction of body fat and blood glucose, thereby improving obesity, diabetes, and hyperlipidaemia. The disclosed AMPK activating material contains, as active ingredients having an improving and treating effect on metabolic syndrome, including obesity, diabetes, and hyperlipidaemia, a novel compound 2?,3?,12?-trihydroxydammar-20(22)-E,24-diene-3-O-[?-D-glucopyranosyl-(1?)-?-D-glucopyranoside], named Damulin A, and a novel compound 2?,3?,12?-trihydroxydammara-20,24-diene-3-O-[?-D-glucopyranosyl-(1?)-?-D-glucopyranoside], named Damulin B.

  • Publication number: 20120083525
    Abstract: The present invention relates to a 2,5-bis-aryl-3,4-dimethyltetrahydrofuran lignan compound which activates nutmeg-derived AMP-activated protein kinase (AMPK), and to a composition including same as active ingredients for preventing and treating metabolic syndromes such as obesity. More particularly, the present invention relates to an AMPK-activating compound comprising one of the 2,5-bis-aryl-3,4-dimethyltetrahydrofuran lignan-based compounds produced by extracting Myristica fragrans with a solution of 30% or less of ethanol and separating and purifying the extracts using chromatography, as expressed in chemical formula 1 below, and to a composition comprising same as an active ingredient for preventing and treating metabolic syndrome caused by AMPK enzyme activation, such as obesity, diabetes, high cholesterol and cardiopulmonary diseases.

  • Patent number: 7060714
    Abstract: The invention is aimed at discovering a new type of anti-cancer compound which can exert an excellent inhibitory activity against the heparanase. A fungal strain Acremonium sp. MT70646 (KCTC 8973P) was isolated from the soil. From the culture of the isolated fungal strain, novel compounds that can inhibit both heparinase and heparanase was purified. Therefore, the present invention regards to provide a newly isolated fungal strain Acremonium sp. MT70646 (KCTC 8973P), its new products, and pharmaceutical agents such as a heparinase inhibitor, a heparanase inhibitor, a metastasis inhibitor and an angeiogenesis inhibitor all of which contain the above new compounds produced by the fungal strain as an active ingredient.
