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.

Anacardic Acid (6-pentadecylsalicylic Acid) is an effective inhibitor of p300 and p300 CBP-associated factor histone acetyltranferases. It also has antimicrobial activity, antibacterial activity, and inhibits prostaglandin synthase, lipoxygenase, and tyrosinase.

Delphinidin chloride, a natural plant pigment found in berries and red wine, is a precursor of certain anthocyanins. Delphinidin chloride induces the release of nitric oxide from the vascular endothelium, resulting in vascular relaxation. At the dose of 1-40 μM, epithelial growth factor receptor signaling and estrogen receptor α expression were inhibited, which was associated with apoptosis and autophagy. Delphinidin chloride regulates JAK STAT3 and MAPKinase signaling. Delphinidin also inhibited the histone acetyltransferase activity of p300 CBP (IC50 was about 30 μM).
