Ethnopharmacological relevanceCucumis prophetarum (L.) is used in traditional Indian medicine for the treatment of inflammation related problems.Aim of the studyThe present investigation was designed to study the effect of N-Trisaccharide (a new compound isolated from the fruit of C. prophetarum (L.)) on hyperglycemia in streptozotocin (STZ)–nicotinamide (NA) induced type 2 diabetic rats.Materials and methodsDifferent doses of N-Trisaccharide (25 and 50 mg/kg b.w.) were administered once daily for 28 days to STZ–NA induced diabetic rats. Plasma insulin and glycogen levels were measured. The activities of hexokinase, glucose-6-phosphatase, fructose-1,6-bisphosphatase, glucose-6-phosphate dehydrogenase, glycogen synthase and glycogen phosphorylase were measured. Further, histological studies on pancreas were also carried out.ResultsThe active compound at doses of 25 and 50 mg/kg b.w. given orally for 14 days showed 47.7% and 69.3% antihyperglycemic activity, respectively. Treatment at the same doses for 28 days provided complete protection against STZ–NA challenge (65 and 230 mg/kg b.w., respectively), intraperitoneally. N-Trisaccharide significantly (p ≤ 0.05) increased the plasma insulin and liver glycogen levels in diabetic rats. The altered enzyme activities of carbohydrate metabolism in the liver and kidney of the diabetic rats were significantly (p ≤ 0.05) improved. Additionally, N-Trisaccharide increased glycogen synthase and decreased glycogen phosphorylase activity in diabetic rats. Histological studies confirmed an increase in insulin level is due to stimulation of injured pancreatic β-cells.ConclusionThe results of the study suggested that N-Trisaccharide possesses propitious effect on STZ–NA induced type 2 diabetes, indicating its usefulness in diabetes management.
