Oleocanthal is a secoiridoid polyphenol that has been found in O. europaea and has diverse biological activities.1,2,3,4 It inhibits the proliferation of CWR-R1ca, PC3, PC-3M, and DU145 prostate cancer cells (IC50s = 3.59, 0.64, 1.03, and 5.35 µM, respectively).1 Oleocanthal inhibits the growth of L. major promastigotes and amastigotes in vitro (IC50s = 18.7 and 87 µg/ml, respectively) and reduces lymph node parasite burden in a mouse model of leishmaniasis when administered at a dose of 5 mg/kg.2 Oleocanthal (5 mg/kg) reduces hippocampal amyloid-β (Aβ) levels in a TgSwDI transgenic mouse model of Alzheimer’s disease.3 Intragastric administration of oleocanthal (5 mg/kg) decreases serum IL-6 and TNF-α levels and reduces lung cell apoptosis in a chicken model of LPS-induced acute lung injury.4
