摘要
Objective:To examine the hepatoprotective effects of gedunin in streptozotocin(STZ)-induced diabetic rats.Methods:Rats were divided into 4 groups:control,STZ,gedunin,and STZ+gedunin.Biochemical parameters for liver function and liver histology were studied.The molecular interaction of gedunin with the liver glucose transporters GLUT2 and SGLT1 was examined using AutoDock Vina.Results:Gedunin attenuated STZ-induced increase in the levels of aspartate transaminase,alanine transaminase,alkaline phosphatase,lactate dehydrogenase and gamma-glutamyl transferase in the serum and liver tissue,reduced lipid peroxidation,and enhanced antioxidant activity.Histopathological studies showed considerable restoration of liver architecture in gedunin-treated diabetic rats.In silico studies revealed stable binding of gedunin with GLUT2 and SGLT1.Conclusions:Gedunin exerts hepatoprotective effects in STZ-induced diabetic rats by reducing liver enzymatic activities and oxidative stress.Further studies are warranted to verify the mechanism of its hepatoprotective action.
