Abstract
AbstractPhotothermal therapy (PTT) has been extensively developed as an effective approach against cancer. However, PTT can trigger inflammatory responses, in turn simulating tumor regeneration and hindering subsequent therapy. A therapeutic strategy was developed to deliver enhanced PTT and simultaneously inhibit PTT‐induced inflammatory response. 1‐Pyrene methanol was utilize to synthesize the anti‐inflammatory prodrug pyrene–aspirin (P‐aspirin) with a cleavable ester bond and also facilitate loading the prodrug on gold nanorod (AuNR)‐encapsulated graphitic nanocapsule (AuNR@G), a photothermal agent, through π–π interactions. Such AuNR@G‐P‐aspirin complexes were used for near‐infrared laser‐triggered photothermal ablation of solid tumor and simultaneous inhibition of PTT‐induced inflammation through the release of aspirin in tumor milieu. This strategy showed excellent effects in vitro and in vivo.
