Mitochondrial uncouplers have shown efficacy in various diseases and are being actively studied for the purposes of antitumor therapy.</p> <p><bold>Aim.</bold> To study the effects of platinum (II) carbene complexes causing depolarization of inner mitochondrial membrane on glioblastoma cells with varying initial sensitivity to chemotherapy for evaluation of possibility of using mitochondrial uncouplers for overcoming drug resistance in this tumor.</p> <p><bold>Materials and methods.</bold> Cytotoxic effect was evaluated using MTT assay, mitochondrial potential level using JC-1 cation dye, proliferative activity of the cells using 5-ethynyl-2’-deoxyuridine with iF555 fluorescent probe. Statistical data processing was performed in RStudio using R programming language.</p> <p><bold>Results.</bold> Comparable cytotoxic effect of platinum (II) carbene complexes in А172 and T98G glioblastoma cell lines was observed. Treatment of both lines causes statistically significant changes in the condition of inner mitochondrial membrane. Moreover, one of the compounds was more effective in the T98G cell line which is considered to be more resistant to chemical agents. All mitochondrial uncouplers caused statistically significant decrease in proliferative activity.</p> <p><bold>Conclusion.</bold> Platinum (II) carbene complexes have cytotoxic effect in glioblastoma cells with varying initial sensitivity to chemotherapy. Additionally, high efficacy and promise of these compounds as potential agents for overcoming resistance were demonstrated.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Преодоление резистентности к терапии злокачественных новообразований является одной из приоритетных задач современного здравоохранения. Перспективными в этом отношении считаются митохондриальные разобщители, показавшие эффективность при различных заболеваниях и активно изучающиеся в настоящее время в качестве противоопухолевых агентов.</p> <p><bold>Цель исследования</bold> – изучение эффектов карбеновых комплексов платины (II), вызывающих деполяризацию внутренней мембраны митохондрий, на клетки глиобластомы с различной исходной чувствительностью к химиотерапии для оценки перспективы использования митохондриальных разобщителей для преодоления лекарственной устойчивости этой опухоли.</p> <p><bold>Материалы и методы.</bold> Цитотоксический эффект оценивали с помощью МТТ-теста, уровень потенциала митохондрий – катионного красителя JC-1, оценку пролиферативной активности клеток исследовали с использованием 5-этинил-2-дезоксиуридина с флуоресцентным зондом iF555. Статистическую обработку данных проводили в программе RStudio на языке программирования R.</p> <p><bold>Результаты.</bold> Установлен сопоставимый цитотоксический эффект карбеновых комплексов платины (II) относительно клеточных линий глиобластомы А172 и T98G. Обработка обеих линий вызывала статистически значимые изменения состояния внутренней мембраны митохондрий, при этом для одного из соединений с большей эффективностью в отношении линии T98G, считающейся более устойчивой к воздействию химических агентов. Все митохондриальные разобщители приводили к статистически значимому снижению пролиферативной активности.</p> <p><bold>Заключение.</bold> Установлено, что карбеновые комплексы платины (II) обладают цитотоксическим эффектом в отношении клеток глиобластомы с различной исходной чувствительностью к химиотерапии. Также показана высокая эффективность и перспективность данных соединений в качестве потенциальных агентов для преодоления резистентности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>mitochondrial uncoupler</kwd><kwd>platinum (II) complexes</kwd><kwd>resistance</kwd><kwd>glioblastoma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>митохондриальный разобщитель</kwd><kwd>комплекс платины (II)</kwd><kwd>резистентность</kwd><kwd>глиобластома</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>26-25-20154</award-id></award-group><funding-statement xml:lang="en">The study was carried out at the expense of a grant from the Russian Science Foundation (grant No. 26-25-20154; https://rscf.ru/project/26-25-20154/).</funding-statement><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда (грант № 26-25-20154; https://rscf.ru/project/26-25-20154/).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Demine S., Renard P., Arnould T.
