ABSTRACT

The protective effect of dendrodoine analog (DA) [4-amino-5-benzoyl-2-(4-methoxy phenylamino) thiazole] at three doses (5, 10, and 15 mg/kg body weight) was investigated on ethanol-induced hyperlipidemia. Hepatotoxicity was induced by administering 7.9 g ethanol/kg body weight for 45 days by intragastric intubation. Our results showed increased activity of aspartate transaminase (AST), alkaline phosphatase (ALP), and gamma glutamyl transferase (GGT) and increased levels of cholesterol, triglycerides, and phospholipids in the plasma of alcohol-given group when compared with normal control group. The levels of tissue (liver and kidney) cholesterol and triglycerides were increased significantly in alcohol control rats when compared with normal control rats. The levels of phospholipids decreased significantly in the liver and kidney of alcohol control rats when compared with normal control rats. The activity of phospholipase A and phospholipase C increased significantly in the liver of alcohol control rats when compared with normal control rats. Intragastric administration of DA at 10 mg/kg body weight effectively lowered the activity of hepatic marker enzymes (GGT, AST, and ALP), phospholipase A, and phospholipase C, and decreased the levels of plasma and tissue lipids. The level of tissue phospholipids increased significantly when DA was administered at a dose of 10 mg/kg body weight along with alcohol when compared with alcohol control group. Thus, we propose that DA exerts a hepatoprotective effect by modulating liver marker enzymes and lipid levels at a dosage of 10 mg/kg body weight.
