    Core-crosslinked polymeric micelles with controlled release of covalently entrapped doxorubicin

  • Original language description

    A physically entrapped anticancer drug (paclitaxel) was previously shown to be rapidly eliminated from the circulation, likely because the drug was insufficiently retained in the micelles. To fully exploit the EPR effect for drug targeting, a DOX methacrylamide derivative (DOX-MA) was covalently incorporated into the micellar core by free radical polymerization. The structure of the doxorubicin derivative is susceptible to pH-sensitive hydrolysis, enabling controlled release of the drug in acidic conditions (in either the intratumoral environment and/or the endosomal vesicles). The entire drug payload was released within 24 h incubation at pH 5 and 37 °C, whereas only around 5% release was observed at pH 7.4. DOX micelles showed higher cytotoxicity inB16F10 and OVCAR-3 cells compared to DOX-MA, likely due to cellular uptake of the micelles via endocytosis and intracellular drug release in the acidic organelles.
