Аннотация:This review presents a wide range of tetrapyrrole photosensitizers used for photodynamic therapy (PDT), antimicrobial
photodynamic therapy, photoinactivation of pathogens. Methods of synthesis and design of new photosensitizers
with greater selectivity of accumulation in tumor tissue and increased photoinduced antitumor activity are considered.
The issues of studying the properties of new photosensitizers, their photoactivity, the ability to generate singlet
oxygen, and the possibility of using targeted photodynamic therapy in clinical practice are discussed. The review examines
the work on PDT by national and foreign researchers.
