  • Patent number: 10098853
    Abstract: Disclosed are a composition for preventing and treating atherosclerosis which includes chalcone compound. In particular, the chalcone compound bound with 2-hydroxyl in ring A and 4?-methyoxy in ring B has versatile therapeutic potentials on anti-atherosclerosis by acting as PPAR? inducer, p44/42 MAPK inhibitor and cell cycle blocker and does not show toxicity to human aortic smooth muscle cells (HASMCs). In addition, the chalcone compound exhibits synergistic effect with the PPAR? ligand (rosiglitazone) to inhibit cell proliferation and the upregulation of cyclin D1, cyclin D3, interleukin-1? (IL-1?) and interleukin-6 (IL-6) induced by oxidized low density lipoprotein (Ox-LDL).

  • Publication number: 20180015090
    Abstract: The present invention relates to a novel type of PPAR? modulator having a pyrimido[5,4-d]pyrimidine main structure. The PPAR? modulator can enhance the expression and nuclear translocation of PPAR? in cells. The present invention also relates to a pharmaceutical composition comprising the PPAR? modulator of the invention encapsulated in a pharmaceutically acceptable cell-penetrating drug delivery system so that it can be directly delivered into cells. The present invention thus provides a method of preventing or treating PPAR?-related disorders or conditions comprising administering to a subject in need thereof a therapeutically effective amount of the PPAR? modulator of the invention or the pharmaceutical composition of the invention.

  • Publication number: 20170252393
    Abstract: The Toona sinensis extract of the present invention is prepared using supercritical fluid technique, wherein the method includes steps of: (a) drying the leaves of T. sinensis; (b) pulverizing the leaves as particles; and (c) extracting the particles with supercritical carbon dioxide to obtain the T. sinensis extract. This supercritical T. sinensis extract not only can decrease blood sugar level, but also promotes lipid degradation, inhibits the formation of huge lipid droplet and improves the metabolic symptoms. Accordingly, the T. sinensis extract further is able to be prepared as food supplement and pharmaceuticals.

  • Patent number: 9241962
    Abstract: A preparation method for a water extract of the fruiting body of Antrodia camphorata (ACW) is provided. The method includes steps of: (a) providing the fruiting body; and (b) boiling the fruiting body in water to obtain the water extract. This polysaccharide-rich water extract from A. camphorata induces the maturation of dendritic cells, enhances T cell proliferation and INF-? production, and polarizes them toward the Th1 pathway. ACW can be effectively applied in cancer immunotherapy.

  • Patent number: 9085520
    Abstract: Disclosed is a chalcone composition for treating diabetes and metabolic syndromes. In particular, the chalcone compound bound with 2-halogen in ring A significantly decreases the blood glucose level in the in vitro anti-diabetic effect experiment. In the in vivo animal model, the leading chalcone compound can prevent the progression of diabetes and control the blood glucose level, and there is no significant difference in the gains in body weight. Throughout the seven-week administration, there are no hepatic or renal toxicity observed.

  • Patent number: 8883167
    Abstract: A preparation method for an ethanol extract of the fruiting body of Antrodia camphorata (EEAC) is provided. The preparation method includes steps of: (a) providing the fruiting body of A. camphorata (AC); (b) extracting the fruiting bodies with a first ethanol solution; and (c) obtaining EEAC. EEAC further can be sequentially extracted or fractioned by n-hexane, ethyl acetate and ethanol, and an n-hexane fraction (FC), an ethyl acetate fraction (FA) and an ethanol fraction (FB) respectively are generated. The growth inhibition and apoptosis induction of leukemia cell line HL 60 are effectively mediated by FA product, in which zhankuic acid A is the bioactive marker. The amount of triterpenoid in the fruiting body of AC can be determined by NMR and HPLC analysis.
