概要 Lipid nano-emulsions (LNEs) having a mean droplet size of approximately 50 nm were investigated as drug carriers for paclitaxel (TXL) to achieve its satisfactory loadings and to develop a pharmaceutically acceptable alternative to the current formulation, Taxol. TXL was incorporated into the LNEs at 2.0 mg/ml without changes in particle size or drug precipitation. In the cytotoxicity study, TXL-loaded LNEs had cytotoxicity to HeLa cells equivalent to that of TXL alone; the 50% growth inhibitory concentrations (IC(50)) of TXL-loaded LNEs and TXL alone were 1.53 +/- 0.23 nM and 1.76 +/- 0.08 nM, respectively. However, a cellular accumulation study using 1,6-diphenyl-1,3,5-hexatriene (DPH) as a fluorescent probe showed that the accumulation of DPH-loaded LNEs in HeLa cells was remarkably lower than that of DPH alone. These results indicated that LNEs were a useful vehicle for TXL, even though LNEs themselves could not be efficiently accumulated in HeLa cells.
