BRD4-IN-11 is an orally active and selective inhibitor of BRD4 with an IC50 of 26.35 nM for BD1 and 72.81 nM for BD2. Its potency against BRD4 is approximately 3 to 18 times greater than against BRr2, BRD3, and BRDT. BRD4-IN-11 increases H2S release and inhibits the upregulation of fibrosis markers (alpha-SMA and fibronectin), c-Myc, and CDC25B. It also reduces apoptosis in LO2 hepatic cells. In liver and lung fibrosis models, BRD4-IN-11 significantly improves liver and lung function, making it suitable for research on liver and lung fibrosis.
