In this study, supramolecular prodrug vesicles with efficient property for dual chemotherapy were successfully constructed. The vesicles release both the anticancer drug doxorubicin (DOX) and prodrug betulinic acid (BA-D) for combinational chemotherapy. The experiments showed enhanced anticancer efficiency and reduced systematic toxicity in tumor-mice.
Supramolecular prodrug vesicles with efficient property for dual chemotherapy have been successfully constructed based on the orthogonal self-assembly between a water-soluble pillar[5]arene host (WP5) and a betulinic acid guest (BA-D) as well as doxorubicin (DOX). Under the acidic microenvironment of cancer cells, both the encapsulated anticancer drug DOX and prodrug BA-D can be effectively released from DOX-loaded WP5 superset of BA-D prodrug vesicles for combinational chemotherapy. Furthermore, bioexperiments indicate that DOX-loaded prodrug vesicles can obviously enhance the anticancer efficiency based on the cooperative effect of DOX and BA-D, while remarkably reducing the systematic toxicity in tumor-mice, displaying great potential applications in combinational chemotherapy for cancer treatments.
