Alkyne-Polysarcosine

Alkyne-polysarcosine (alk-polysarcosine) is a lipopeptide conjugate of the endogenous amino acid sarcosine (N-methylated glycine). pSar, as a polymer, combines water solubility, protein resistance, low It has excellent characteristics such as cytotoxicity and non-immunogenicity, and has strong stealth characteristics of endogenous materials. It is considered a potential alternative to polyethylene glycol (PEG).
