[HYPOLIPIDEMIC, ANTIOXIDANT, AND ENDOTHELIAL PROTECTIVE EFFECT OF COMPOUND ZB-16 (NOVEL GPR119 RECEPTOR AGONIST) IN RATS WITH EXPERIMENTAL TYPE 2 DIABETES.]

The effect of compound ZB-16 (a new GPR1 19 receptor agonist) after two-week administration on the endothelial function, glucose and lipid metabolism (total cholesterol, LDL, HDL and triglycerides), lipid peroxidation, and antioxidant system status in rats with experimental type-2 diabetes mellitus (T2DM) has been studied. It was found that the untreated control group of animals exhibited, in addition to sustained hyperglycemia, a decrease in endothelium-dependent vaso- dilation and antioxidant system activity, and increase in the content of LDL and the dyslipidemic index. Administration of ZB-16 (1 mg/kg, p.o.) in rats with T2DM model resulted in reduction of the endothelial dysfunction (improved endothelium-dependent vasodilation by 83% as compared to the control group, p < 0.05). ZB-16 also produced a moderate antioxidant effect of reducing the content of TBA-active products (by 30% as compared to the untreated control, p <0.05) and favored normalization of lipid metabolism indicators.
