  • Publication number: 20140228427
    Abstract: The present invention relates to a pharmaceutical composition for the prevention or treatment of asthma comprising Wogonin as an active ingredient. The Wogonin of the present invention is excellent not only in relieving airway hypersensitivity that causes asthma in vivo, in inhibiting reactive oxygen species generation in the airway, and in inhibiting the infiltration of inflammatory cells in the bronchus, but also in inhibiting the generation of IgE in serum and bronchoalveolar lavage fluid, and in inhibiting the expressions of Th2 cytokines in the lung. Therefore, the Wogonin of the present invention can be effectively used as a composition for the prevention, treatment, or improvement of asthma.

  • Patent number: 8722110
    Abstract: Disclosed is a pharmaceutical composition for the prophylaxis and therapy of inflammatory diseases, allergic diseases, or asthma, comprising a velvet apple (Diospyros blancoi A. DC.) extract as an active ingredient. Having the inhibitory activity against the nuclear translocation of NF-?B, whose level is rapidly elevated in response to inflammatory stimuli, the velvet apple extract can suppress the production of NO and PGE2, the expression of iNOS and COX-2, and the release of IL-1? and TNF-?, and can significantly down regulate Th2-mediated IL-4 and IL-13 production. In addition, the extract was found to inhibit the activation of eosinophils in bronchoalveolar lavage fluid, and to suppress the secretion of immunoglobulins and chemokines in bronchoalveolar lavage fluid and blood, as measured by in vivo tests on an ovalbumin-induced asthma mouse model. Therefore, the extract can be used in the method for preventing or treating various inflammatory disorders, allergic diseases, or asthma.

  • Publication number: 20130244959
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating asthma, the composition containing styraxlignolide A or an aglycone thereof as an active ingredient. More particularly, styraxlignolide A compound is one separated from stems and barks of Styrax japonica, and styraxlignolide A or homoegonol, which is an aglycone of styraxlignolide A and which has improved safety, has the effect of attenuating weight loss and airway hyperresponsiveness, inhibiting the generation of reactive oxygen species in airway, inhibiting generation of IgE, TGF-?1, and IL-17 in the serum and bronchoalveolar lavage fluid, inhibiting endobronchial inflammatory cell infiltration, and inhibiting the formation of a mucous plug and subepithelial fibrosis in an asthma-induced mouse model. Therefore, styraxlignolide or homoegonol can be effectively used as the active ingredient of a pharmaceutical composition for preventing or treating bronchial asthma in which airway remodeling has progressed.

  • Publication number: 20130108652
    Abstract: The present invention relates to a kit for the diagnosis or screening of asthma comprising neuropilin (NRP) gene, and to a method for screening a therapeutic agent for asthma using the same. More precisely, the present invention confirmed that NRP1 expression was increased in asthma patients and by D. pteronissinus extract. Based on the confirmation, the inventors confirmed that NRP1 could be effectively used as a target for the development of a therapeutic agent for asthma since the suppression of NRP1 expression resulted in the decrease of mRNA, protein, enzyme activity, and promoter activity of MMP-9 in relation to asthma.

  • Publication number: 20120308676
    Abstract: The present invention relates to an antiviral composition containing an Aleurites fordii or Daphne kiusiana extract or a fraction thereof as an active ingredient. In detail, extracts of Aleurites fordii or Daphne kiusiana or fractions thereof can induce the secretion of an immune-related cytokine, interferon-? (IFN-?) in natural killer (NK) cells, and thus exhibit potent antiviral activity and superior effects for viral diseases, and therefore can be effectively used in an antiviral composition.
