Epigenetic reader domain inhibitors, mostly bromodomain inhibitors, block recognition of acetylated histone lysines. Structural work on a histone acetyltransferase bromodomain first showed that this module binds acetylated lysine. Proteins of the bromodomain and extra-terminal (BET) family, such as bromodomain-containing protein 4 (BRD4), link histone acetylation to gene transcription. The thienodiazepine (+)-JQ1 was described in 2010 as a selective BET inhibitor that displaces BRD4 from chromatin. PFI-1, GSK1324726A and CPI-203 provide further BET inhibitor chemotypes for comparative studies. Other entries reach beyond BET binding, such as SGC-CBP30 for a non-BET bromodomain and the BRD4-degrading compound ARV-825.
