The p300 inhibitor specifically regulates the expression of genes that induce fibrosis, thereby acting only on fibrotic tissues and reducing the risk of adverse effects on normal tissues. Because the inhibitor blocks multiple fibrotic signaling pathways, it may be effective for fibrosis in various organs such as the liver, lungs, and kidneys. In addition, by modulating gene expression, the inhibitor has the potential to address the fundamental cause of the fibrotic process. The present invention is characterized in that bronopol is first identified as a specific example of such a p300 inhibitor. In particular, bronopol is an FDA-approved drug with established safety, and therefore is expected to reduce the time and cost required for conducting clinical trials.
