| Title: | A novel inhibitor of stearoyl-CoA desaturase-1 attenuates hepatic lipid accumulation, liver injury and inflammation in model of nonalcoholic steatohepatitis. |
| Abstract: | Stearoyl-CoA desaturase-1 (SCD-1) catalyzes the biosynthesis of monounsaturated fatty acids, and their abnormality is possibly responsible for obesity, insulin resistance, hepatic steatosis and nonalcoholic steatohepatitis (NASH). A novel SCD-1 inhibitor, N-(2-hydroxy-2-phenylethyl)-6-[4-(2-methylbenzoyl)piperidin-1-yl]pyridazine-3-carboxamide, has been obtained. The compound inhibited liver SCD-1 activity and increased liver triglyceride accumulation in mice fed with non-fat, high-sucrose diets. In order to evaluate the effects of the SCD-1 inhibitor on NASH development, rats were fed with lipogenic methionine and choline-deficient (MCD) diets for 8 weeks. The SCD-1 inhibitor was administered once-daily at a dose of 30 or 100 mg/kg/d by oral gavage. Administration of a high dose of the SCD-1 inhibitor decreased triglyceride accumulation in the liver of NASH rats by 80%. Administration of a high dose of the SCD-1 inhibitor attenuated the increase of aspartate aminotransferase (AST) and alanine transaminase (ALT) by 86% and 78%, respectively. Hepatic steatosis, hepatocellular degeneration and inflammatory cell infiltration were histologically observed in the liver of NASH rats, and administration of the SCD-1 inhibitor ameliorated these crucial observations in NASH. In summary, an SCD-1 inhibitor ameliorated hepatic triglyceride accumulation, liver injury, hepatocellular degeneration and inflammation in experimental NASH models. These results suggest that SCD-1 maybe a promising target for the treatment of NASH. |
