Конденсированные производные бензимидазолдиона с узловым атомом азота могут стать основой для разработки эффективных клинических терапевтических средств для лечения онкологических заболеваний. Для этого необходимо проведение исследований, включающих синтез и изучение противоопухолевой активности соединений данной группы.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Поиск новых цитотоксических агентов из ряда конденсированных бензимидазолдионов с узловым атомом азота.</p></sec><sec><title>Методы</title><p>Методы. Цитотоксический профиль синтезированного соединения оценивали с использованием МТТ-теста, в основе которого лежит реакция восстановления соли тетразолия (3-(4,5-диметилтиазол-2-ил)-2,5-дифенил-тетразолиум бромид) митохондриальными дегидрогеназами живых клеток до нерастворимых в воде кристаллов формазана. В качестве показателей эффективности были определены величины IC50 цитотоксического эффекта, представляющие собой концентрации соединения, приводящие к гибели 50 % клеток в пробе.</p></sec><sec><title>Результаты</title><p>Результаты. Было продемонстрировано наличие цитотоксичности у нового производного бензимидазола – 7-бром-8-хлор-3,4-дигидро-1H-[1,4]оксазино[4,3-a]бензимидазол-6,9-диона в отношении клеток опухолевого происхождения: аденокарциномы легкого (A549) и аденокарциномы молочной железы (MCF-7). В свою очередь для нормальных клеток эмбриональной почки человека (Hek-293) данное соединение было примерно в 2,5 раза менее токсично.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты показывают, что конденсированные производные бензимидазола с узловым атомом азота являются перспективным классом соединений для разработки новых противоопухолевых агентов с избирательной токсичностью.</p></sec></abstract><trans-abstract xml:lang="en"><p>Condensed benzimidazoledione derivatives with a nodal nitrogen atom can become the basis for the development of clinical therapeutic agents for the effective treatment of oncological diseases.

The cytotoxic profile of the synthesized compound was evaluated using an MTT test based on the reduction reaction of tetrazolium salt (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide) by mitochondrial dehydrogenases of living cells to formazane crystals insoluble in water. The IC50 values of the cytotoxic effect, which are concentrations of a compound leading to the death of 50 % of cells in a sample, were determined as indicators of effectiveness.</p></sec><sec><title>Result</title><p>Result. The cytotoxicity of a new benzimidazole derivative, 7-bromo-8-chloro-3,4-dihydro-1H-[1,4]oxazino[4,3-a]benzimidazole-6,9-dione, was demonstrated against two tumor cell lines: lung adenocarcinoma (A549) and breast adenocarcinoma (MCF-7).
