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-β1, 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.
本发明涉及一种用于预防或治疗哮喘的药物组合物,该组合物含有styraxlignolide A或其去糖苷作为活性成分。更具体地说,styraxlignolide A化合物是从日本安息香的茎和树皮中分离出来的,styraxlignolide A或homoegonol,后者是styraxlignolide A的一个去糖苷,具有改善安全性的效果,具有减轻体重减少和气道高反应性、抑制气道内活性氧种的生成、抑制血清和支气管肺泡灌洗液中IgE、TGF-β1和IL-17的生成、抑制支气管内炎症细胞浸润、抑制黏液栓和支气管黏膜下纤维化在哮喘诱导小鼠模型中的形成。因此,styraxlignolide或homoegonol可以有效地用作预防或治疗气道重塑已进展的支气管哮喘的药物组合物的活性成分。
