Combinational delivery of hydrophobic and hydrophilic anticancer drugs in single nanoemulsions to treat MDR in cancer.

ABSTRACT: In this study, we developed the core-matched nanoemulsions (NEs) functionalized by vitamin E (VE) and tocopherol poly(ethylene glycol)succinate (TPGS) to codeliver hydrophobic and hydrophilic drugs, paclitaxel (PTX) and 5-fluoroucacil (5-FU), in order to achieve synergistic effects and overcome PTX resistance in a multi-drug-resistant (MDR) human epidermal carcinoma cell line KB-8-5. Antitumor effect of the combination therapy based on core-matched technology (CMT) was evaluated in vitro and in vivo in mice. The core-matched NEs showed entrapment efficiency of >90% and were of nanoscale particle size and negative zeta-potential. The combined core-matched NEs exhibited concentration and time-dependent cytotoxicity against PTX-sensitive KB-3-1 cells and PTX-resistant KB-8-5 cells as well as
