Abstract
- This work presents a versatile strategy for the synthesis of dual stimuli‐responsive amphiphilic glycomacromolecules with tailored release properties. Amphiphilic precision glycomacromolecules (APGs) derived from tailor‐made building blocks using solid phase polymer synthesis form glycofunctionalized micelles, a versatile class of materials with applications in drug delivery, as antiinfection agents as well as simple cell mimetics. In this work, this concept is extended by integrating cleavable building blocks into APGs now allowing stimuli‐responsive release of glycan ligands or destruction of the micelles. This study incorporates a newly designed acid‐labile building block, 4‐(4‐(((((9H‐fluoren‐9‐yl)methoxy)carbonyl)amino)methyl)‐1,3‐dioxolan‐2‐yl)benzoic acid (DBA), suitable also for other types of solid phase or amide chemistry, and an established UV‐cleavable 2‐nitrobenzyl linker (PL). The results demonstrate that both linkers can be cleaved independently and thus allow dual stimuli‐responsive release from the APG micelles. By choosing the APG design e.g., placing the cleavable linkers between glycomacromolecular blocks presenting different types of carbohydrates, they can tune APG and micellar stability as well as the interaction and cluster formation with a carbohydrate‐recognizing lectin. Such dual‐responsive glycofunctionalized micelles have wide potential for use in drug delivery applications or for the development as anti‐adhesion agents in antiviral and antibacterial treatments.
