AcPBE-PEG-DSPE

Acetylphenylboronic acid pinacol ester-poly(ethylene glycol)-1,2-Distearoyl-sn-glycero-3-phosphoethanolamine (AcPBE-PEG-DSPE) is an amphiphilic PEG lipid combining a di-C18 acyl phospholipid anchor with a defined-length hydrophilic PEG segment. Discrete chain lengths with different degrees of polymerization are available. The acetyl carbonyl retains a derivatization handle, while the pinacol ester retains a protected boron group, allowing the two transformations to be performed sequentially. It can be used to construct interfaces in membrane-related systems and nanoparticle formulations, enabling comparisons of anchoring structure, hydrophilic chain length, terminal functionality, and formulation dispersion.
