Anacardicacid diene is a polyunsaturated form of anacardicacid that has been found in cashew nut shell liquid. It has antibacterial activity against methicillin resistant S. aureus (MRSA) and S. mutans (MICs = 12.5 and 6.25 μg ml, respectively). Anacardicacid diene has schistosomicidal activity against adult S. mansoni worms when used at a concentration of 100 μM. It also inhibits soybean lipoxygenase-1 in a time-dependent manner.
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 anacardicacid . At 30-60 μM, CAY10669 can dose-dependently inhibit histone H4 acetylation in HepG2 cells in vitro.
