Abstract:

Nanoparticles with typical core-shell structure were prepared with a blend of methoxypoly(ethylene glycol)-poly(lactide)copolymer (MPEG-PLA) and poly (lactic acid) (PLA) along with paclitaxel by the O/W solvent evaporation method. An orthogonalexperiment L9(3)3 was applied to get the best preparation conditions. The core-shell paclitaxel-loaded MPEG-PLA/PLA nanoparticleswith the highest drug loading efficiency were obtained when amount of MPEG-PLA, time of ultrasonication and volume of deionized water were 300 mg, 10 min and 30 mL, respectively. The release behavior of paclitaxel from the optimal MPEG-PLA/PLA nanoparticles showed that 22% of paclitaxel was released in 14 d. When incubating with human nasopharyngeal carcinoma cells expressing LMP1, these optimal nanoparticles showed a little lower tumor growth compared with free paclitaxel.
