Erucin is an isothiocyanate derived from glucoerucin, a glucosinolate predominant in arugula (Eruca sativa Mill.) and other cruciferous vegetables. At 2.5-5 μM erucin can induce significant neuroprotective and antioxidant effects, increasing both total glutathione levels and total antioxidant capacity at the cytosolic level in dopaminergic-like neuroblastoma SH-SY5Y cells.[1] Growth inhibition, cell cycle regulation, apoptosis, and induction of detoxification enzymes have all been reported from use of erucin in prostate, lung, liver, and colon cancer cells.[2][3]
