Abstract

Diabetes is a serious health problem and a source of risk for numerous severe complications such as obesity and hypertension. Treatment of diabetes and its related diseases can be achieved by inhibiting key digestive enzymes related to starch and lipid digestion. The findings revealed that the administration of trigonelline to surviving diabetic rats helped to protect the pancreas β-cells from death and damage. Additionally, the supplement of trigonelline to surviving diabetic rats significantly decreased intestinal α-amylase and maltase by 36 and 52%, respectively, which led to a significant decrease in the blood glucose rate by 46%. Moreover, the administration of trigonelline to surviving diabetic rats potentially inhibited key enzymes of lipid metabolism and absorption such as lipase activity in the small intestine by 56%, which led to a notable decrease in serum triglyceride (TG) and total cholesterol (TC) rates and an increase in the HDL cholesterol level. This treatment also improved glucose, maltase, starch, and lipid oral tolerance. Trigonelline was also observed to protect the liver-kidney functions efficiently, which was evidenced by the significant decrease in the serum aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transpeptidase (GGT), and lactate dehydrogenase (LDH) activities and creatinine, albumin, and urea rates. The histological analysis of the pancreas, liver, and kidney tissues further established the positive effect of trigonelline. Overall, the findings presented in this study demonstrate that the administration of trigonelline to diabetic rats can make it a potentially strong candidate for industrial application as a pharmacological agent for the treatment of hyperglycemia, hyperlipidemia, and liver-kidney dysfunctions.
