Abstract :

The effect of electron-accepting substituents in position 3 of the chlorine p6 macrocycle in neutral and carboxyl-containing negatively charged cycloimide derivatives of chlorin p6 (CIC) on the photochemical and biological properties of these photosensitizers was studied. The relationship between the structure and properties of CICs was analyzed on the basis of information on their photoinduced cytotoxicity, efficiency of generation of reactive oxygen species, photostability, intracellular localization, quantitative parameters of accumulation in cells, and cellular pharmakinetics. It was shown that these compounds can be used for the development of photosensitizers with intense light absorption at 740 nm, controlled intracellular localization, and a high photodynamic activity toward tumor cells.
