   <abstract xml:lang="ru">
    <p>В работе продемонстрирована возможность мониторинга ответа опухолевых клеток на фотодинамическое воздействие с помощью фотосенсибилизатора порфиразиновой природы со свойствами вязкостного сенсора. Исследование выполнено с использованием тетрапиррольного красителя - тетра(4-бензилоксифенил)тетрацианопорфиразина. Показано, что порфиразин эффективно поглощает и флуоресцирует в области «окна прозрачности» биологических тканей и демонстрирует свойства флуоресцентного молекулярного ротора, проявляя высокую чувствительность параметров флуоресценции к изменениям вязкости среды. Установлено, что основными местами внутриклеточной локализации порфиразина являются околоядерная область клетки и ядерная оболочка или непосредственно примыкающие к ней структуры. Продемонстрирована высокая фотодинамическая активность порфиразина в отношении клеток эпидермоидной карциномы кожи человека. В экспериментах in vitro зарегистрировано увеличение времени жизни возбужденного состояния порфиразина в клетках после фотодинамического воздействия, свидетельствующее об увеличении локальной внутриклеточной вязкости и начавшихся необратимых дегенеративных процессах, влекущих за собой гибель опухолевых клеток.</p>

    <p>The possibility of monitoring of cancer cells response to photodynamic treatment by the use of porphyrazine photosensitizer as a viscosity sensor is shown. The research was done with tetrapyrrole dye - tetra(4- benzyloxyphenyl)tetracyanoporphyrazine. The dye was shown to demonstrate effective absorption and fluorescence in biological transparent window. In addition, the dye has a molecular rotor properties showing high sensitivity of fluorescence parameters to media viscosity changes. Pre-nuclear region and nuclear membrane or its environment are shown to be the primary space of intracellular accumulation of the dye. The high photodynamic activity of the porphyrazine was detected in relation to epidermoid carcinoma cells of human skin. The significant increase of fluorescence life-time of the dye inside the cells was registered after the photodynamic therapy. It may be concerned as an evidence of the local intracellular viscosity increase and a verification of irreversible degenerative processes onset, leading to the death of cancer cells.</p>
