n-trans-feruloyloctopamine and Non-alcoholic-Fatty-Liver-Disease

Hepatic oxidative stress plays a key role in the development of non-alcoholic steatohepatitis (NASH), therefore, treatment approaches that address the antioxidant is helpful in the therapy of patients with NASH. N-trans-coumaroyloctopamine (1) and N-trans-feruloyloctopamine (2) were identified as the primary antioxidant constituents of garlic skin with high antioxidant activities. The aim of this study was to elucidate the protective effect and mechanism of the antioxidants on NASH in rats. The results provide morphological and molecular biological evidences for the protective role of the antioxidant 2 in ameliorating oxidative stress and hepatic apoptosis in experimental NASH for the first time. Mechanism study indicated that the antioxidant 2 significantly reduced the expression of COX-2 mRNA and protein by western blot, RT-PCR and immunohistochemical techniques.
