Abstract

Bifunctional supramolecular prodrug vesicles have been successfully constructed based on the complexation between a glutathione (GSH)-responsive prodrug guest molecule (DNS-CPT) and a water-soluble pillar[5]arene (WP5) for cancer diagnosis and therapy. Under the microenvironment of cancer cells with high GSH concentration, 7-ethyl-10-hydroxycamptothecin (SN-38) with strong yellow fluorescence can be efficiently released from the prodrug DNS-CPT for drug location and cancer therapy.
