Alaternin (Catharticin) is an anthraquinone compound with antioxidant and hepatoprotective activities. Alaternin has an inhibitory activity against hydroxyl radicals generated in a cell-free chemical system (FeSO4/H2O2) with an IC50 value of 3.05 μM. Alaternin exhibits hepatoprotective activity against Tacrine (HY-111338)-induced toxicity in human hepatic HepG2 cells with an EC50 value of 4.02 μM[1].
