Background/aims: Diabetic nephropathy is a common complication of diabetes. This study explored the renal protective effect and possible mechanism of gliquidone in mice with diabetic nephropathy.

Methods: Animal model of diabetic nephropathy was established in KKAy mice. The renal protective effect of gliquidone was studied by evaluating the kidney function through measures of urinary protein, blood urea nitrogen (BUN), serum creatinine (Scr) and serum triglyceride (TG) that were performed using an automatic biochemical analyzer. The levels of oxidative stress indicators, such as nitric oxide (NO), superoxide dismutase (SOD) and malondialdehyde (MDA), were evaluated in renal tissue homogenates using the automatic biochemical analyzer. The inhibitory effect of gliquidone on renal interstitial fibrosis and its association with Notch / Snail1 signaling pathway in diabetic nephropathy was investigated using molecular biological techniques.

Results: It was found that low-, medium- and high-dose gliquidone improved the mice’s general health condition, such as mental status, fur condition, eating, and drinking. Gliquidone reduced the body weight and the kidney weight /body weight ratio of mice. Gliquidone improved the kidney function, indicated by reductions in urinary protein, blood urea nitrogen, and serum creatinine and triglyceride. Gliquidone treatment increased levels of nitric oxide and superoxide dismutase, but decreased level of malondialdehyde. The expression of Jagged1/Notch1/hes1/Snail1/α-SMA decreased, while the expression of E-cadherin increased in gliquidone-treated kidneys. High dose gliquidone showed the best effect, one that was similar to that of the positive control drug irbesartan.

Conclusion: Taken together, our results suggested that gliquidone can ameliorate the diabetic symptoms of diabetic nephropathy through inhibiting Notch / Snail1 signaling pathway, improving anti -oxidative response and delaying renal interstitial fibrosis. The efficacy of gliquidone is dose-dependent.

Diabetes mellitus is a major health problem due to its increasing prevalence and life-threatening complications. Antidiabetic sulfonylureas represent the first-line drugs in type 2 diabetes even though the most common associated risk is pharmacologically-induced hypoglycemia. In the development of this side effect are involved several factors including the pharmacokinetic and pharmacodynamic profile of the drug, patient age and behavior, hepatic or renal dysfunctions, or other drugs associated with a high risk of interactions. If all these are controlled, the risk-benefit balance can be equal to other oral antidiabetic drugs.

Simple, smart and sensitive normal fluorescence and stability-indicating derivative synchronous spectrofluorimetric methods have been developed and validated for the determination of gliquidone in the drug substance and drug product. Normal spectrofluorimetric method of gliquidone was established in methanol at λ excitation 225nm and λ emission 400nm in concentration range 0.2-3μg/ml with LOD equal 0.028. The fluorescence quantum yield of gliquidone was calculated using quinine sulfate as a reference and found to be 0.542. Stability-indicating first and third derivative synchronous fluorescence spectroscopy were successfully utilized to overcome the overlapped spectra in normal fluorescence of gliquidone and its alkaline degradation product. Derivative synchronous methods are based on using the synchronous fluorescence of gliquidone and its degradation product in methanol at Δ λ50nm. Peak amplitude in the first derivative of synchronous fluorescence spectra was measured at 309nm where degradation product showed zero-crossing without interference. The peak amplitudes in the third derivative of synchronous fluorescence spectra, peak to trough were measured at 316,329nm where degradation product showed zero-crossing. The different experimental parameters affecting the normal and synchronous fluorescence intensity of gliquidone were studied and optimized. Moreover, the cited methods have been validated as per ICH guidelines. The peak amplitude-concentration plots of the derivative synchronous fluorescence were linear over the concentration range 0.05-2μg/ml for gliquidone. Limits of detection were 0.020 and 0.022 in first and third derivative synchronous spectra, respectively. The adopted methods were successfully applied to commercial tablets and the results demonstrated that the derivative synchronous fluorescence spectroscopy is a powerful stability-indicating method, suitable for routine use with a short analysis time. Statistical comparison between the results obtained by normal fluorescence and derivative synchronous methods and the official one using student’s t-test and F-ratio showed no significant difference regarding accuracy and precision.
