제목 Paclitaxel-loaded Lipiodol Nanoemulsions Stabilized by Polyglycerol-poly(-caprolactone) Block Copolymers
초록 Polyglycerol-based amphiphilic copolymers have gained much attention as a novel biomaterial in the biomedical field because of the biocompatibility and facile chemical modification capability of polyglycerol.  Here, we fabricate cancer-targeted theranostic polymeric nanoemulsions composed of linear polyglycerol-poly(ε-caprolactone) (PG-PCL) diblock copolymer as a polymeric shell and CT contrast agent lipiodol as a core oil. PG-PCLs are synthesized through ring-opening polymerization, and folates are conjugated to the hydroxyl moieties of polyglycerol block with 19.2 % degree of substitution. The incorporated lipiodol facilitates to encapsulate water-insoluble anticancer drug paclitaxel in the nanoemulsion due to its high solubility of paclitaxel. In vitro studies with HeLa ovarian cancer cells demonstrate excellent anti-cancer activities (LD50 < 3 ng mL-1) and the applicability as a contrast agent for CT imaging.  We anticipate our PG-PCL amphiphilic polymer can be widely applied to drug delivery nanocarriers for cancer-targeting of therapeutic and imaging agents.
