Application

I-CBP112 has been used in cell culture and sample preparation, to verify the acetylation of VPS34 (vacuolar protein sorting 34), by p300 at K29, K771 and K781 and to diminish synergistic gene expression.

Biochem/physiol Actions

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. For full characterization details, please see I-CBP112 on the Structural Genomics Consortium (SGC) website.

I-CBP112 is also known as (1-[7-(3,4-dimethoxyphenyl)-9-{[(3S)-1-methylpiperidin-3-yl]-methoxy}-2,3,4,5-tetrahydro-1,4-benzoxazepin-4-yl]propan-1-one). It has the ability to induce full-length p300/CBP nucleosome acetylation. It is a competitive inhibitor of acetyl-lysine. I-CBP112 regulates transcription of key inflammatory genes.
