Objectives: The current experimental study was make attempt to explore the renal protective effect of gallic acid- metformin (GA-Met) against the STZ induced diabetic rats via inhibition of DPP-4 and TGF-β.
Methods: GA-Met was scrutinizing against the DPP-4 inhibitor. GA-Met were also examined via Insilco study with the structure of DPP-4 to identify the critical interactions for its bioactivity. STZ was used for induction the type 2 diabetes and blood glucose level, biochemical, antioxidant, cytokines and inflammatory mediators were estimated.
Results: DPP-4 assay, GA-Met was found as potential drug with IC50 value = 4.34 M. GA-Met Insilco interacted with various residue of DPP-4 inhibitor. GA-Met significantly reduced the blood glucose level (67%) and increased the plasma insulin level (45.5%). GA-Met improve the interstitial fibrosis, tubulointestitial injury and inflammatory cell infiltration in animal tissue. GA-Met exhibited the significantly decreasethe level of TNF-α (45%), Il-1β (54.3%). IL-6 (56.1%), caspase-1 (43%), caspase-3 (40.4%), COX-2 (65%). PGE2 (60.3%) and NF-kB (52.3%). Oxidative stress marker and the expression of transforminggrowth factor-β (TGF-β) in the renal tissue of diabetic rats were significantly (P<0.001) altered by GA-Met treated group rats.
Conclusions: The current investigation suggests that GA-Met exert the renal protective effect against the STZ induced DN rats via inhibition of DPP4 and TGF-β.
