AI Technical Summary

Technical Problem

Existing peptides face challenges with physicochemical stability and bioavailability, particularly in normal saline, which limits their therapeutic effectiveness.

Method used

The simultaneous addition of arginine amide at the C-terminus and acetylation of the N-terminus in peptide derivatives, such as Ac-Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val-Arg-NH2, enhances stability and biological activity.

Benefits of technology

This modification significantly improves the stability and biological activity of the peptides, addressing the limitations of existing peptide therapies.
