  • In recent years, inhibition of the interaction between the bromodomain and extra-terminal domain (BET) family of chromatin adaptors and acetyl-lysine residues on chromatin has emerged as a promising approach to regulate the expression of important disease-relevant genes, including MYC, BCL-2, and NF-κB ...

    In recent years, inhibition of the interaction between the bromodomain and extra-terminal domain (BET) family of chromatin adaptors and acetyl-lysine residues on chromatin has emerged as a promising approach to regulate the expression of important disease-relevant genes, including MYC, BCL-2, and NF-κB. Here we describe the identification and characterization of a potent and selective benzoisoxazoloazepine BET bromodomain inhibitor that attenuates BET-dependent gene expression in vivo, demonstrates antitumor efficacy in an MV-4-11 mouse xenograft model, and is currently undergoing human clinical trials for hematological malignancies (CPI-0610).
