Phototherapy (namely photodynamic therapy (PDT) and photodynamic inactivation (PDI) of microorganisms) is an alternative method for the treatment of these diseases. That requires adequate photosensitizers and, in this sense, boron-dipyrromethenes (BODIPYs) have interesting properties to act as phototherapeutic agents. In the present review, first, we describe the different strategies used to increase reactive oxygen species production. Then, we explain different architectures developed aiming to enhance the solubility of BODIPYs in biological media in order to optimize their targeting and delivery into the cells to be treated. Finally, we discuss the design of BODIPYs that are activated by specific stimuli present in the target tissues, allowing increasing the selectivity of the treatment. The data presented and discussed here show that BODIPYs are outstanding photosensitizers for the treatment of tumors and infections in the presence of oxygen and light.Graphical abstract
