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.

HeatShockProtein 27 (HSP27) is a member of small heatshockproteins with a highly-conserved α-crystalline domain. It inhibits aggregation of damaged proteins through a complex structural systems of phosphorylation-dependent oligomerization and self-assembly. It has been demonstrated that HSP27 is involved in a variety of pathophysiological pathways with negative or positive protective activities
