Abstract:
Metal‐free long‐wavelength light‐driven prodrug photoactivation is highly desirable for applications such as neuromodulation, drug delivery, and cancer therapy. Herein, via triplet fusion, we report on the far‐red light‐driven photo‐release of an anti‐cancer drug by coupling the boron‐dipyrromethene (BODIPY)‐based photosensitizer with a photocleavable perylene‐based anti‐cancer drug. Notably, this metal‐free triplet fusion photolysis (TFP) strategy can be further advanced by incorporating an additional functional dopant, i.e. an immunotherapy medicine inhibiting the indoleamine 2,3‐dioxygenase (IDO), with the far‐red responsive triplet fusion pair in an air‐stable nanoparticle. With this IDO inhibitor‐assisted TFP system we observed efficient inhibition of primary and distant tumors in a mouse model at record‐low excitation power, compared to other photo‐assisted immunotherapy approaches. This metal‐free TFP strategy will spur advancement in photonics and biophotonics fields.
