General Description
N₃-Polysarcosine (N₃-pSar) is a functional polypeptoid derived from poly(N-methylglycine) and equipped with a terminal azide functionality. Polysarcosine has emerged as an attractive alternative to polyethylene glycol (PEG) due to its excellent aqueous solubility, biodegradability, low immunogenicity, and reduced protein adsorption.
The terminal azide group readily participates in copper-catalyzed azide-alkyne cycloaddition (CuAAC) and strain-promoted azide-alkyne cycloaddition (SPAAC) reactions with alkyne- and DBCO-containing molecules. This enables efficient conjugation of peptides, proteins, antibodies, fluorophores, nucleic acids, nanoparticles, and targeting ligands. N3-pSar is frequently utilized for polymer therapeutics, nanoparticle engineering, molecular imaging, and advanced drug delivery systems.
