dCBP-1(Cat No.:I044565)is a potent and selective inhibitor of the CREB-binding protein (CBP) and its paralog p300, both of which are histone acetyltransferases (HATs) involved in chromatin remodeling and transcriptional regulation. dCBP-1 disrupts the interaction between CBP/p300 and transcriptional activators, thereby modulating gene expression linked to cell growth, differentiation, and oncogenesis. It exhibits high selectivity and efficacy in preclinical models, making it a valuable chemical probe for studying epigenetic mechanisms. dCBP-1 holds therapeutic potential in cancer and inflammatory diseases where CBP/p300-mediated transcriptional dysregulation plays a key role.
