Abstract: OBJECTIVE: To investigate protective effects of a catalytic antioxidant AEOL-10150 against nitrogen mustard-induced liver injury and related mechanisms. METHODS: A single intraperitoneal injection of nitrogen mustard hydrochloride (2 mg/kg) was used to construct a nitrogen mustard-induced acute liver injury model in C57BL/6 mice. AEOL-10150 (5 mg/kg) was given 0.5 and 6 h for treatment intervention after nitrogen mustard exposure,and sacrificed after 3 days of exposure. For clarifying the AEOL-10150 has a protective effect on nitrogen mustard-induced liver injury in mice,the following indicators were evaluated:gross liver tissue changes and pathological changes by HE stain;serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities;liver tissue reactive oxygen species (ROS) level,malondialdehyde (MDA) content;reduced glutathione (GSH) content;liver tissue redox regulatory molecule Nrf-2 mRNA and protein expression level;liver tissue myeloperoxidase (MPO) activity,and serum inflammatory factors TNF-α,IL-1β content. RESULTS: A single intraperitoneal exposure of 2 mg/kg nitrogen mustard successfully induced oxidative damage and inflammatory response in livers of mice in the 3rd day. Compared with nitrogen mustard-exposed mice,the AEOL-10150 intervention reduced liver tissue pathological damage,decreased serum ALT and AST activities,and significantly reduced liver tissue ROS and MDA levels,accompanied by the increased GSH content and the decreased Nrf-2 level. In addition,the liver tissue MPO activities and serum TNF-α and IL-1β concentrations of mice in the AEOL-10150 intervention group were significantly lower than those in the nitrogen mustard-exposed group. CONCLUSION: AEOL-10150 effectively alleviated the acute liver injuries which were induced by nitrogen mustard in mice,and its mechanism might be related to direct antioxidant effect and anti-inflammatory effect.
