Description: I-CBP112 is a selective inhibitor of the bromodomain-containing transcription factors CREBBP (CBP) and EP300 (IC50 = 0.142 and 0.625 μM, respectively). I-CBP112 has little activity against other bromodomains at concentrations up to 1 mM. I-CBP112 targets the CBP/p300 bromodomains. I-CBP112 significantly reduced the leukemia-initiating potential of MLL-AF9(+) acute myeloid leukemia cells in a dose-dependent manner in vitro and in vivo. Interestingly, I-CBP112 increased the cytotoxic activity of BET bromodomain inhibitor JQ1 as well as doxorubicin.

Additional Information

CREBBP (CBP) and EP300 are general transcriptional co-activators, which are involved in many biological processes like maintenance of genomic stability by affecting DNA replication and DNA repair as well as cell growth, transformation and development. They also plays and essential role in neuronal plasticity/ memory formation, hematopoiesis and energy homeostasis as demonstrated in a variety of mouse models. By acetylation of non-histone proteins CREBBP can have a positive or negative effect on transcriptional regulation affecting protein- protein interactions, protein-DNA interactions, nuclear retention or protein half-life.

Mutations of CREBBP and EP300 lead to Rubinstein-Taybi syndrome (RTS), characterised by growth retardation, facial abnormalities, organ abnormalities, mental retardation and proneness to tumors. Chromosomal translocations of CREBBP or EP300 with MOZ, MLL have been observed in acute myeloid leukemia. CREBBP has also been associated with Amyotrophic lateral sclerosis (ALS), Lou Gherig’s disease, a neurodegenerative disease with progressive degeneration of motor neurons in the brain and spinal cord, Alzheimer's disease and polyglutamine diseases such as Spinal and Bulbar Muscular Atrophy and Huntington’s disease
