Application

PEG-SS-PLGA is a redox responsive, biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic poly(lactide-alternative-glycolide) (PLGA) block, with a reducible disulfide linkage between blocks. This polymer can be fabricated into Glutathione (GSH) responsive nanoparticles which can be used as an intracellular drug delivery system.

Different from common Poly(lactide-co-glycolide) (PLGA) polymer, the lactic and glycolic units in Poly(lactide-alt-glycolide) block alternate in sequence in the polymer chain, and the molar ratio of lactic to glycolic units in the polymer is exactly 1:1.

Poly(lactide-alt-glycolide) exhibits excellent solubility in common organic solvents, such as acetonitrile, acetone, dioxane, DCM, and THF, providing great convenience for drug delivery researches and applications.
