DC-CPin711, a potent and selective inhibitor of the bromodomain of CREB-binding protein (CBP) with an IC50 of 0.0626 μM, effectively halts the cell cycle at the G1 phase and promotes apoptosis [1].
CAY10669 is an inhibitor of the histone acetyltransferase PCAF (p300 CREB-binding protein-associated factor; IC50 = 662 μM), displaying a 2-fold improvement in inhibitory potency over anacardic acid . At 30-60 μM, CAY10669 can dose-dependently inhibit histone H4 acetylation in HepG2 cells in vitro.
NASTRp, an inhibitor of CREB-CBP complex, possesses anti-cancer effects along with cell cycle regulation, autophagy suppression, and endoplasmic reticulum stress.
