摘要
Glutathione thiol-reactive pillar[6]arene(TWP6)is designed and synthesized as the first example of reducing agent-reactive host molecule.TWP6 shows high affinity binding towards suitable anti-tumor drugs and guests.Doxorubicin-based acid-labile prodrugs and TWP6 are used to construct supramolecular vesicles,which are also loaded with camptothecin.The supramolecular vesicles loaded with two drugs demonstrate glutathione-and acid-responsive drug release as well as sequential release to both stimuli types.Supramolecular vesicles show combination therapeutic effect towards tumor cells in vitro.
