Garcinol is an inhibitor of the histone acetyltransferases (HATs) p300 and PCAF with IC50 of 7 and 5 uM, respectively. It also inhibits the HAT GCN5 in Cryptococcus neoformans, inducing temperature sensitivity and impairing growth. A polyisoprenylated benzophenone isolated from Garcinia indica, garcinol promotes neurogenesis and ex vivo expansion of human hematopoietic stem cells. It induces apoptosis in several types of cancer cells and has anti-inflammatory actions.
