Supramolecular chemotherapy is currently a new strategy to improve the therapeutic efficacy as well as overcome the side effects of traditional chemotherapy. Herein, a supramolecular chemotherapy platform based on the pegylated guanidinium-modified calix[5]arene pentadodecyl ether (GC5A-12C) nanoassembly was prepared. Three commercially available antitumor drugs: oxaliplatin, methotrexate and chlorambucil, all showed strong binding to this GC5A-12C nanocarrier. The supramolecular nanodrugs achieved higher anticancer performances compared with free drugs in cell experiments. Furthermore, the cellular uptake mechanisms and efficacy are confirmed by fluorescence imaging.
