  • Publication number: 20190008820
    Abstract: The present invention relates to a pharmaceutical composition containing a monoacetyldiacyiglycerol compound as an active ingredient for preventing or treating asthma, and a functional health food composition for preventing or treating asthma. The monoacetyldiacylglycerol compound of the present invention inhibits the expression of IL-4 in EL-4 cells, which are mouse T cell lymphoma cells, reduces hypersensitivity of airway in an asthma-induced animal model, and inhibits the infiltration of inflammatory cells into the bronchial tube. In addition, the compounds of the present invention inhibit the generation of IgE in the serum and bronchoalveolar lavage fluid, have an excellent effect of inhibiting the expression of Th2 cytokines (IL-4, IL-5, and IL-13) in the lung, thereby overcome side effects of the currently used therapeutic agents for asthma, have no toxicity, and exhibit a superior therapeutic effect, and thus can be useful as a composition for preventing, treating, and alleviating asthma.

  • Patent number: 9895337
    Abstract: The invention relates to pharmaceutical compositions, as well as health functional food compositions and quasi-drug compositions, for preventing, treating, or improving rheumatoid arthritis, comprising a monoacetyldiacylglycerol compound as an active ingredient. The monoacetyldiacylglycerol of the invention is effective in inhibiting the phosphorylation of STAT-3 known to be a therapeutic target for rheumatoid arthritis. As the monoacetyldiacylglycerol is an effective therapeutic agent without toxicity, the monoacetyldiacylglycerol can overcome the side effects of the medicines currently used in the treatment of rheumatoid arthritis. Thus, the monoacetyldiacylglycerol can be used for preventing, treating or improving rheumatoid arthritis.
