AI Technical Summary

Technical Problem

Current treatments for type 2 diabetes, such as DPP-IV inhibitors, often require injection due to long peptide sequences and potential side effects, limiting their application and convenience.

Method used

Development of a multi-peptide sequence derived from hemp seeds, specifically peptides like IPVIA, IPVA, IPTA, IPVVA, IPVPA, VVPL, VPKPL, VPSL, IPPA, VIPL, VPAL, VPVVL, VPIIL, HAYVFGVEDTLNALESGAIETLIVWENLDINR, and YVFGVEDTLNALESGAIETLIVWENLDINR, which can inhibit DPP-IV, promoting GLP-1 and PYY secretion, thereby regulating blood sugar levels without significant side effects and allowing oral administration.

Benefits of technology

The hemp-derived peptides effectively inhibit DPP-IV, enhancing glucose tolerance, improving insulin resistance, and balancing blood glucose levels with minimal side effects, offering a safer and more convenient treatment option compared to existing DPP-IV inhibitors.
