CF53 is a highly potent, selective, and orally active inhibitor of BET protein, with a Ki of <1 nM, Kd of 2.2 nM, and an IC50 of 2 nM for BRD4 BD1. CF53 binds to both the BD1 and BD2 domains of BRD2, BRD3, BRD4, and BRDT BET proteins with high affinities, being very selective over non-BET bromodomain-containing proteins. CF53 exhibits potent anti-tumor activity both in vitro and in vivo.

CPI-637 is a selective and cell-active benzodiazepinone CBP EP300 bromodomain inhibitor.

JQAD1 is a potent and selective histone acetyltransferase EP300 degrader (PROTAC®; DC50≤ 31.6 nM); comprises an EP300 inhibitor, A485, joined by a linker to a cereblon E3 ligase ligand. JQAD1 brings about degradation of EP300 in neuroblastoma cell lines in a proteasome-dependent manner. JQAD1 suppresses both H3K27ac and EP300 expression levels and induces apoptosis. JQAD1 suppresses tumors growth in NSG mice xenografted with Kelly cells. CRC and MYCN genes are downregulated in tumors treated with JQAD1. JQAD1 exhibits no significant effect on coactivator CBP at concentrations inducing EP300 degradation.

CBP EP300-IN-1 is a CBP EP300 bromodomain inhibitor.
