   <abstract xml:lang="ru">
    <p>Современные препараты для лечения онкозаболеваний обладают повышенной токсичностью для организма. Также известны случаи, когда клетки опухолей проявляют резистентность к определённым классам препаратов. Поэтому поиск и исследование новых соединений, обладающих противоопухолевыми свойствами, остаётся актуальной задачей. В последние годы возник интерес к антиоксидантной и противоопухолевой активности катехинов, которые относятся к растительным флавоноидам, а потому их применение в терапии, а также их совместное использование с более токсичными соединениями может снизить негативное воздействие лечения на организм в целом. Обычно противоопухолевая активность определяется возможностью связывания соединений с ДНК. В работе проводится изучение взаимодействия ДНК с катехином в растворе, а также рассматривается влияние на ДНК одновременного введения в раствор катехина и ионов железа. Показано, что молекулы катехина с ДНК не взаимодействуют, тогда как присутствие ионов железа способствует формированию комплексов ДНК-катехин-железо, в которых, как ожидается, катехин сможет проявить свою биологическую активность. При достаточно больших концентрациях хлорида железа в растворах катехина образуются дискретные наночастицы. Использовали методы УФ-спектрофотометрии, низкоградиентной вискозиметрии, динамического рассеяния света и атомной силовой микроскопии.</p>

    <p>Modern anticancer drugs have increased toxicity to the human body. There are also cases when tumor cells show resistance to certain classes of drugs. Therefore, the search and study of new compounds with antitumor properties remains an urgent task. In recent years, interest has arisen in the antioxidant and antitumor activity of catechins, which belong to plant flavonoids, and therefore their use in therapy, as well as their combined use with more toxic compounds, can reduce the negative impact of treatment on the body as a whole. Typically, antitumor activity is determined by the ability of compounds to bind to DNA. The paper studies the interaction of DNA with catechin in solution, and also considers the effect DNA of the simultaneous introduction of catechin and iron ions into the solution on DNA conformation. It has been shown that catechin molecules do not interact with DNA, while the presence of iron ions promotes the formation of DNA-catechin-iron complexes, in which catechin is expected to be able to exhibit its biological activity. The discrete nanoparticles are formed at sufficiently high concentrations of Fe3+ ions in catechin solutions. The methods used were UV spectrophotometry, low-gradient viscometry, dynamic light scattering, and atomic force microscopy.</p>
