RT Journal Article T1 A highly fluorescent and readily accessible all-organic photosensitizer model for advancing image-guided cancer PDT A1 Garcia Sampedro, Andrés A1 Prieto Castañeda, Alejandro A1 Rodríguez Agarrabeitia, Antonia A1 Bañuelos Prieto, Jorge A1 García Moreno, Inmaculada A1 Villanueva Oroquieta, Ángeles A1 Moya Cerero, Santiago de la A1 Ortiz García, María Josefa A1 Acedo Núñez, Pilar AB The potential of using image-guided photodynamic therapy (ig-PDT) for cancer, especially with highly biocompatible fluorescent agents free of heavy atoms, is well recognized. This is due to key advantages related to minimizing adverse side effects associated with standard cancer chemotherapy. However, this theragnostic approach is strongly limited by the lack of synthetically-accessible and easily-modulable chemical scaffolds, enabling the rapid design and construction of advanced agents for clinical ig-PDT. In fact, there are still very few ig-PDT agents clinically approved. Herein we report a readily accessible, easy-tunable and highly fluorescent all-organic small photosensitizer, as a model design for accelerating the development and translation of advanced ig-PDT agents for cancer. This scaffold is based on BODIPY, which assures high fluorescence, accessibility, and ease of performance adaptation by workable chemistry. The optimal PDT performance of this BODIPY dye, tested in highly resistant pancreatic cancer cells, despite its high fluorescent behavior, maintained even after fixation and cancer cell death, is based on its selective accumulation in mitochondria. This induces apoptosis upon illumination, as evidenced by proteomic studies and flow cytometry. All these characteristics make the reported BODIPY-based fluorescent photosensitizer a valuable model for the rapid development of ig-PDT agents for clinical use.
