Abstract:

The available conventional remedies for the treatment of drug-induced liver diseases are highly inadequate and possess serious adverse effects; therefore, the development of new, effective drugs is considered necessary. This article explores the hepatoprotective and antioxidant potential of 7-methylcoumarin (MC) and 7-methoxycoumarin (MOC) in CCl(4)-induced hepatotoxicity in rats. MC and MOC individually, at doses of 50 and 100 mg/kg body weight, were administered orally once-daily for 7 days. The hepatoprotective activity was assessed using various biochemical parameters, such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum bilirubin (TB), total protein (TP), and albumin (TA). Serum antioxidant enzyme [e.g., superoxide dismutase (SOD) and catalase (CAT)] levels were determined. Also, thiobarbituric-acid-related substances (TBARS) levels, along with histopathological studies of liver tissue, were scrutinized. Pretreatment with MC and MOC significantly decreased ALT, AST, and TB in the serum of CCl(4)-induced liver damaged rats in a dose-dependent manner. TA and TP levels in the serum were also restored significantly in all presupplemented MC and MOC groups. In addition, oxidative stress induced by CCl(4) was prevented significantly; thereby, increasing SOD and CAT levels and decreasing TBARS levels in liver homogenates. Histopathological studies revealed the ameliorative natures of both the compounds. This study demonstrates the strong hepatoprotective activity of MC and MOC, which could be attributed to their potent antioxidant effects.
