Hesperetin-loaded chitosan nanoparticles ameliorate hyperglycemia by regulating key enzymes of carbohydrate metabolism in STZ-induced high-fat diet fed diabetic Wistar rats

Abstract Type II diabetes mellitus (T2DM) is the most common severe metabolic disease and is considered one of the top five causes of death worldwide. Screening blood glucose levels measured in obese individuals is more effective in identifying undiagnosed individuals than screening tests in the general population and therefore introduces selection bias in detection from a molecular and morphological standpoint, so this paradigm can be used to investigate the antidiabetic efficacy of medicinal plants or herbs. Hesperetin, due to its therapeutic efficacy. Hesperetin has been demonstrated to have positive benefits, however, it falls short of being completely effective because of its weak water solubility and bioavailability. Our study aims to create chitosan nanoparticles with hesperetin to improve antidiabetic effects in rats with obesity-related diabetes caused by a high-fat diet. Accordingly, the experimental animals were made diabetic by feeding them a high-fat diet for 28 days followed by injection of a low dose of streptozotocin (STZ) (35 mg/kg b.w; 0.1 M citrate buffer; pH 4.0) were made diabetic and a significant (P < 0.05) decrease in blood glucose and glycosylated hemoglobin was observed along with an increase in plasma insulin levels. The existence of dimension, shape, and size has been confirmed by characterization investigations such as SEM, zeta potential, particle size analyzer, and FT-IR examination. Blood glucose, insulin levels, total glycogen, and carbohydrate metabolism are biochemical variables. Overall, the 20 mg/kg b.w the effective findings of hesperetin-loaded chitosan nanoparticles (HSPCNPs) demonstrate potent anti-inflammatory, antidiabetic, and antiobesity agents.
