General description

A cell-permeable bis-arylidene cyclohexanone compound that acts as a p300/CBP-selective histone acetyltransferase inhibitor (IC50 = 5 µM), while it affects GCN5 and PCAF only at much higher concentrations (30% and 0% inhibition, respectively, at 5 µM inhibitor concentration). Shown to decrease histone H3 acetylation (IC50 ≤ 40 µM) and induce chromatin condensation in HeLa cells.
