One of the advantages of PDT is that it can often circumvent tumor resistance to chemotherapeutic agents such as cisplatin and doxorubicin. However, pre‐existing and acquired resistance to PDT has also been demonstrated. One type of resistance, which involves nitric oxide (NO) generated by inducible nitric oxide synthase (iNOS/NOS2) in tumor cells, was discovered in the author's laboratory. When...
Objectives
Photodynamic therapy (PDT) is an effective cancer treatment that uses photosensitizers, light, and oxygen to destroy malignant cells. Porphyrins, and in particular the cationic derivatives, are the most investigated photosensitizers for PDT. In this context, it is important to study new methodologies to develop efficient cationic photosensitizers for use in PDT.
