EDAC-mediated O-acylisourea rearrangement for HA cationization

Also known as: spontaneous O-acylisourea rearrangement, water-based catalyst-free HA cationization

Taxonomy: Technique Branch / Method. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

we reprogram a classically unfavorable EDAC-mediated rearrangement into a productive synthetic route, enabling direct cationization of hyaluronic acid (HA) through spontaneous O-acylisourea rearrangement. This water-based, catalyst-free process achieves up to 70 % substitution

Published Workflows

Objective: Develop a water-based route to cationize hyaluronic acid and use the resulting scaffold to improve the stability and gene-delivery performance of virus-inspired non-viral polymer-DNA nanoparticles.

Why it works: The paper proposes that direct aqueous cationization of HA yields HAA scaffolds that can serve as rigid structural backbones, thereby improving the stability and performance of non-viral polymer-DNA nanoparticles.
