A supramolecular assembly mediated by host–guest interactions for improved chemo–photodynamic combination therapy

Author affiliations

Abstract

We report a supramolecular nanomedicine (SNM-3) based on a camptothecin–tetraphenyl porphyrin conjugate, camptothecin–polyethylene glycol conjugate, and acyclic cucurbit[n]uril. The supramolecular nanomedicine is tunable by varying the composition of the three components to optimize the nanoscale morphology and therapeutic efficacy. The optimized supramolecular nanomedicine possesses great stability and enhanced intracellular singlet oxygen generation efficiency. Cytotoxicity assay demonstrates that SNM-3 improves the efficacy of chemo–photodynamic combination therapy against three cancer cell lines.
