The hepatic injury caused by clofibrate (CF) is strongly associated with oxidative stress and inflammation. This study aims to develop a hypolipidemic compound that possesses antioxidant, anti-inflammatory properties and reduces liver injury. Carvacrol-clofibrate (CF-Carvacrol) was synthesized by optimizing the structure of CF by carvacrol. CF-Carvacrol showed significant lipid-lowering effects in hyperlipidemic mouse models induced by Triton WR 1339. The molecular docking results showed that CF-Carvacrol has a good affinity for PPAR-α. The liver injury study showed that CF-Carvacrol had significantly lower liver injury compared to CF. Manifested as a significant decrease in liver weight and liver coefficient (P < 0.01), as well as a significant decrease in aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) (P < 0.01). Histopathology of liver tissue showed that the necrosis of liver cells, cytoplasmic looseness, nuclear degeneration, and infiltration of inflammatory cells were significantly reduced in the CF-Carvacrol group. CF-Carvacrol can significantly up-regulate the expression of Nrf2 and HO-1 in liver (P < 0.05, P < 0.01). The expression of inflammatory factors TNF-α and IL-6 in the liver was significantly down-regulation (P < 0.05, P < 0.01). The levels of superoxide dismutase (SOD) and glutathione (GSH) significantly increased (P < 0.05, P < 0.01), while the content of malondialdehyde (MDA) in lipid peroxidation significantly decreased (P < 0.01). These results revealed that CF-Carvacrol has significant hypolipidemic activity and mild liver injury, and may exert antioxidant and anti-inflammatory activity by activating the Nrf2/HO-1 signaling pathway to reduce liver injury.
