DSPE-Thioktal-PEGn-OCH?

DSPE-Thioketal-PEGn-OCH₃ is a functional and stimuli-responsive PEG-lipid conjugate consisting of a DSPE lipid anchor, a thioketal linker, and a methoxy-terminated polyethylene glycol (PEG) chain. The amphiphilic structure combines the membrane-anchoring properties of DSPE with the hydrophilic and steric-stabilizing properties of PEG, while the thioketal linker provides a ROS-responsive functional element.

Thioketal groups are susceptible to oxidative cleavage in the presence of reactive oxygen species (ROS), making DSPE-Thioketal-PEGn-OCH₃ a useful building block for the development of ROS-responsive and redox-sensitive nanocarrier systems . The material can be investigated for incorporation into liposomes, lipid nanoparticles, micelles, and other functional nanocarriers for controlled and stimulus-responsive drug delivery.

The PEG chain length can be varied from low to higher molecular weights , allowing adjustment of hydrophilicity, molecular size, steric stabilization, and nanoparticle surface properties. The methoxy-terminated PEG segment can improve aqueous dispersibility and colloidal stability, while the DSPE moiety facilitates incorporation into lipid membranes and lipid-based nanoparticles.
