Exploration of anti-diabetic activity and metabolite profiling of Bruguiera cylindrica (l.) Bl.-in vivo anti-diabetic activity, exploration of molecular mechanism, and network pharmacological analysis.

INTRODUCTION

The Bruguiera cylindrica L. is a mangrove plant that is typically found in coastal areas of Asia, including India. It has been known for its medicinal properties, which have been utilized for generations. For example, in Thailand, it has been used to treat wounds and diarrhoea, while in India, it has been effective in addressing diabetes, ulcers, and other health issues. This particular study sought to investigate the potential of B. cylindrica bark extract in reducing the symptoms of diabetes in rats.

METHODS

In this study, we examined the potential of B. cylindrica bark extract as an inhibitor of α-amylase and α-glucosidase enzymes in vitro. We also evaluated the effects of the extract and Metformin on rats fed high-fat diets and measured their lipid profiles and biochemical parameters. Furthermore, we conducted a network pharmacology analysis to identify proteins and pathways involved in the amelioration of diabetes.

RESULTS

Through metabolite profiling, we identified 58 compounds in B. cylindrica hydroalcoholic extract. These compounds include alkaloids, phenolics, flavonoids, and fatty acids. The extract was found to have a dose-dependent inhibition activity against α-amylase and α-glucosidase, with IC50 values similar to acarbose. In rats, oral administration of 200-400 mg/kg of B. cylindrica led to reduced blood glucose levels and normalized serum biochemical parameters.

CONCLUSIONS

Bruguiera cylindrica bark may reduce blood sugar levels in rats with diabetes. The study found metabolites that interact with protein targets associated with different types of diabetes.
