Abstract

Abstract

En 中文
Poly(ethylene oxide sulfide) (PEOS), polymers consisting of an internal ethylene oxide oligomer and disulfide linkage, were synthesized and characterized. The degree of polymerization was dependent upon temperature, dimethyl sulfoxide condition, and monomer hydrophobicity. The stability of PEOS was measured by the size exclusion chromatography method after the incubation both with and without 5 mM glutathione. The disulfide bond was stable in the extracellular condition but completely degraded in 2 h in the reductive cytosolic condition. Hydrophilic PEOS polymers showed no cytotoxicity on the HepG2 cell line. On the basis of these properties, PEOS can be applied in many drug delivery fields.
