C646, a histone acetyltransferase inhibitor, inhibits p300 (Ki: 400 nM, in a cell-free assay).

Garcinol also inhibits histone acetyltransferases (HATs, IC50= 7 μM) and p300/CPB-associated factor (PCAF, IC50 = 5 μM). Garcinol has anti-inflammatory and anti-cancer activity. Garcinol, a polyisoprenylated benzophenone harvested from Garcinia indica, exerts anti-cholinesterase properties towards acetyl cholinesterase (AChE) and butyrylcholinesterase (BChE) with IC50s of 0.66 μM and 7.39 μM, respectively.

Curcumin D6 (difluoroformylmethane D6) is deuterium-labeled curcumin (Turmeric yellow). Curcumin (Turmeric yellow) is a natural phenolic compound with various pharmacological effects, including anti-inflammatory, antioxidant, anti-proliferative and anti-a

Selective p300 histone acetyltransferase (HAT) inhibitor (IC50 = 50-500 nM). Exhibits approximately 100-fold selectivity for p300 over PCAF (IC50 = 200 μM). Inhibits p300-dependent transcription.

WM-8014 (MOZ-IN-3) is an inhibitor of MOZ(IC50=55 nM), a member of histone acetyltransferases.

TTK21 is an activator of CBP/p300 histone acetyltransferase activity.

Curcumin (Natural Yellow 3) is a phenolic natural product, an inhibitor of histone acetyltransferase p300/CREB (IC50=25 μM) with specificity. Curcumin has a wide range of pharmacological activities such as antitumor, anti-inflammatory and antioxidant.
