Background: Diabetes is one of the most prevalent endocrine disorders in humans, and its first-line medication is metformin. Peroxisome proliferator-activated receptor gamma (PPAR–γ) agonists are the adjuncts to metformin. Bavachinin is a PPAR pan-agonist with fewer side effects than metformin" into PPAR–γ agonists. In this study, the synergistic effects of metformin and Bavachinin were investigated on type II diabetic rats.
Methods: After four weeks of a high fat and glucose diet, type II diabetes was induced in 28 male Wistar rats, using injection of streptozotocin and nicotinamide. The animals were distributed into five groups of seven each: 1) Normal control (N), 2) Diabetic control (D), 3) Diabetic rats receiving metformin (DM), 4) Bavachinin (DB), and 5) Metformin plus Bavachinin (DMB). Oral glucose tolerance test (OGTT), fasting blood glucose (FBG), fasting insulin (FINS), homeostasis model assessment of β-cell function (HOMA-β), homeostasis model assessment of insulin resistance (HOMA-IR), and insulin sensitivity index (ISI) were obtained.
Results: The OGTT results in DM, DB, and DMB groups were significantly improved compared to that of D group. The FBG levels were significantly lower in DMB than in DB, DM, and D groups. The FINS levels of DMB were significantly less than those of DB, DM, and D groups. The HOMA-IR and HOMA-β were comparable between DMB and N groups. The ISI improved significantly in DMB compared to those in DM, DB, and D groups.
Conclusion: Bavachinin may be used combined with metformin for the treatment of type II diabetes at lower doses of metformin, thus having fewer side effects.
