A composition for prevention or treatment of pulmonary fibrosis comprising chromenone derivatives represented by Formula I of the present invention or pharmaceutically acceptable salts thereof as an active ingredient, produces altered heat shock protein 27 (HSP27) dimers, thereby preventing normal HSP27 non-phosphorylated polymers from performing a chaperone function and reducing a cell protection function that chaperone originally performs. Thus the inventive composition has a remarkable inhibitory effect on pulmonary fibrosis, in particular, an irradiation-induced pulmonary fibrosis phenomenon.

色酮衍
生物或其药学上可接受的盐类,可产生改变的热休克蛋白 27(HSP27)二聚体,从而阻止正常的 HSP27 非
磷酸化聚合物发挥伴侣功能,并降低伴侣原本发挥的细胞保护功能。因此,本发明组合物对肺纤维化,特别是辐照诱导的肺纤维化现象具有显著的抑制作用。
