BRD4 Inhibitor-37 is a compound with anticancer activity that has inhibitory activity against BRD4. BRD4 Inhibitor-37 has an IC50 of approximately 0.05-0.1 μM in binding assays and shows a GI50 of 0.1-0.3 μM in cell-based assays. The effect of BRD4 Inhibitor-37 on c-Myc, a downstream protein of BRD4, has been validated, demonstrating its ability to intervene in this signaling pathway. BRD4 Inhibitor-37 exhibits selectivity among five different bromodomain proteins, enhancing its potential as a BET protein inhibitor[1].
