In order to better understand the therapeutic mechanism of dual-function peptide 5rolGLP-HV in treatment of treat diabetes and its complication of thrombosis, the pharmacological effects and pharmacokinetic properties of 5rolGLP-HV were conducted in this study. 5rolGLP-HV was orally administered to diabetic mice, and the hypoglycemic mechanism was investigated. Thrombotic mice were applied to study the thrombus dissolving ability of 5rolGLP-HV. The concentration of rolGLP and rHV in rat plasma following single oral dose or intravenous injection of 5rolGLP-HV was measured. Treatment with 5rolGLP-HV decreased insulin resistance (2.96 ± 1.43 vs. 9.35 ± 1.51, p < 0.05) of diabetic mice. 5rolGLP-HV shortened the length of thrombus in thrombosis mice (2.92 ± 0.74 vs. 5.92 ± 1.16 cm, p < 0.01) and extended the thrombin time (15.35 ± 1.22 vs. 8.67 ± 0.89 s, p < 0.01) of normal mice. Meanwhile, 5rolGLP-HV restored the damage of pancreatic, liver, kidney, and adipose tissues induced in the diabetic mice. 5rolGLP-HV exhibited a fast absorption and slow elimination phase after digested into rolGLP-1 and rHV in vivo. These results suggested that 5rolGLP-HV had an ideal therapeutic potential in the prevention of β cell dysfunction in type 2 diabetes and delay of the thrombus.
