Graphical Abstract

Exogenous myrosinase was encapsulated inside photoresponsive honeycomb-gold nanoparticles to mask enzyme activity and target tumor tissues. Near-infrared light was used to trigger the release of myrosinase, which catalyzed the conversion of nontoxic glucoraphenin to therapeutic sulforaphene at the tumor sites to achieve locoregional chemo-photothermal therapy.

Abstract

Enzymes have been used to direct the conversion of prodrugs in cancer therapy. However, non-specific distribution of endogenous enzymes seriously hinders their bioapplications. Herein, we developed a near-infrared-triggered locoregional chemo-photothermal therapy based on the exogenous enzyme delivery and remolded tumor mivroenvironment. The catalytic efficiency of enzymes was enhanced by the hyperthermia, and the therapeutic efficacy of photothermal therapy (PTT) was improved owing to the inhibition of heat shock protein 90 by chemotherapeutics. The locoregional chemo-phototherapy achieved a one-time successful cure in 4T1 tumor-bearing mice model. Thus, a mutually reinforcing feedback loop between PTT and chemotherapy can be initiated by the irradiation, which holds a promising future in cancer therapy.
