Key Points

This research aims to explore how modifying the backbone of peptides can enhance their stability against proteolytic degradation.
Employing backbone N-heteroatom substitutions in peptide design.
Assessing stability through proteolytic degradation assays in biological environments.
Comparative analysis of modified and unmodified peptides.
Significant increase in proteolytic stability for peptides with N-heteroatom substitutions compared to controls, p<0.01.
Enhanced binding affinity observed for modified peptides on biomolecular surfaces.
Reduction in protease recognition leading to sustained activity in biological trials.

Implication

Study improves peptide proteolytic stability through backbone N-heteroatom substitution, suggesting a new strategy for therapeutic development.

Abstract

Peptide-based ligands are well-suited to engage large biomolecular surfaces but are often limited by rapid proteolytic degradation in biological environments. Backbone modification offers a direct means to disrupt protease recognition...
