Abstract
Aim: The study was designed to assess the effect of piperine on gluconeogenic enzymes in high-fat diet-induced type-2 diabetic rats. Experimental Design: Adult male Wistar rats were used and divided as Group I: Control; Group II: Type-2 diabetic rats; Group III: Type-2 diabetic rats treated with piperine (40 mg/kg body weight [b.wt]/day, orally for 30 days); and Group IV: Type-2 diabetic rats treated with metformin (50 mg/kg b.wt/day, orally for 30 days). After 30 days of treatment, animals were anesthetized; liver tissues were dissected out and used for the assessment of gluconeogenic enzymes such as glucose- 6-phosphatase and phosphoenolpyruvate carboxykinase (PEPCK) Results: In diabetic animals, glucose-6-phosphatase and PEPCK activity were significantly raised (P < 0.05) compared with control animals. Oral administration of the piperine reduced the activity of these enzymes (P < 0.05) to that of the control and standard drug metformin. Conclusion: The present study shows that piperine possesses antidiabetic activity by reducing gluconeogenic enzymes in the liver.
