Abstract
Abstract
Sorafenib-incoporated nanoparticles were prepared using a block copolymer that is composed of dextran and poly(DL-lactide-co-glycolide) [Dexb LG] for antitumor drug delivery. Sorafenib-incorporated nanoparticles were prepared by a nanoprecipitation-dialysis method. Sorafenib-incorporated Dexb LG nanoparticles were uniformly distributed in an aqueous solution regardless of the content of sorafenib. Transmission electron microscopy of the sorafenib-incorporated Dexb LG nanoparticles revealed a spherical shape with a diameter < 300 nm. Sorafenib-incorporated Dexb LG nanoparticles at a polymer/drug weight ratio of 40:5 showed a relatively uniform size and morphology. Higher initial drug feeding was associated with increased drug content in nanoparticles and in nanoparticle size. A drug release study revealed a decreased drug release rate with increasing drug content. In an in vitro anti-proliferation assay using human cholangiocarcinoma cells, sorafenib-incorporated Dexb LG nanoparticles showed a similar antitumor activity as sorafenib. Sorafenib-incorporated Dexb LG nanoparticles are promising candidates as vehicles for antitumor drug targeting.
