Validating the antidiabetic potential of Nakima (Tupistra clarkei Hook.f.), a traditional food from eastern Himalayan region, through network pharmacology and in vivo experimentation.

Abstract

Objective: To explore and understand the antidiabetic activity of Tupistra clarkei Hook.f. inflorescence, providing a scientific explanation to the ethnomedicinal properties.

Methods: The constituents of the plant were determined through GC-MS analysis, which were used for target prediction and network pharmacology to understand how the plant regulates hyperglycaemia and other diabetes complications. These properties were validated in vivo along with further assessment of the antioxidant potential of the plant, both in vitro and in vivo.

Key findings: The plant showed good phenol-flavonoid content, and antioxidant potential both in vitro and in vivo. GC-MS analysis identified 24 constituents of the plant. In silico analysis showed their ability to target 166 proteins that are associated with pathways in controlling hyperglycaemia and other diabetic consequences, protection of pancreatic tissue, insulin secretion, and insulin resistance. This was reflected in the in vivo experiment where T. clarkei showed ability to reduce FBG, LDL-C, VLDL-C levels, improve the levels of HDL-C, and also facilitate reversal of damage in pancreatic islets.

Conclusion: Our study validated the antidiabetic potential Tupistra clarkei inflorescence in the in silico and in vivo assessment, and has proved to have good antioxidant activity and potential against diabetes. However, further clinical trials are essential.
