Tuberculosis (TB) remains one of the deadliest bacterial diseases. The primary challenge in treating tuberculosis infection is the emergence of strains with multidrug resistance (MDR) to 4-9 drugs. The emergence of bacterial strains with MDR is a consequence of patients’ insufficient adherence to treatment, interrupted therapy, improperly prescribed courses of chemotherapy, and, according to recent data, the accumulation of antibiotics in the environment, which can activate the natural drug resistance system in bacteria. The consequences of MDR to antibiotics include prolonged hospitalizations, increased medical expenses, and mortality. Therefore, the task is to develop new effective antibacterial agents with novel mechanisms to reduce the emergence of bacterial resistance. In this study, we investigated the mechanisms of action of new promising antimycobacterial derivatives of quinoxalin-1,4-dioxide on the model organism Mycobacterium smegmatis .</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">По данным Всемирной организации здравоохранения (ВОЗ) устойчивость к антибиотикам является сегодня одной из наиболее серьезных угроз для здоровья человечества, продовольственной безопасности и развития, при этом одним из наиболее смертоносных бактериальных заболеваний остается туберкулез (ТБ). Основной проблемой лечения туберкулезной инфекции является возникновение штаммов с лекарственной устойчивостью (ЛУ) к 4-9 препаратам. Возникновение бактериальных штаммов с ЛУ является следствием недостаточной приверженности лечению пациентов, прерванного лечения, неправильно подобранного курса химиотерапии, а также, по последним данным, накопления антибиотиков в окружающей среде, которые могут приводить к активации природной системы лекарственной устойчивости у бактерий. Следствием ЛУ к антибиотикам являются продолжительные госпитализации, рост медицинских расходов и смертности в связи с чем стоит задача разрабатывать новые эффективные антибактериальные препараты, которые бы обладали новыми механизмами для снижения возникновения бактериальной устойчивости. В данной работе нами были изучены механизмы действия новых перспективных антимикобактериальных производных хиноксалин 1,4-диоксида на модельном объекте Mycobacterium smegmatis .</p></trans-abstract><kwd-group xml:lang="en"><kwd>antibiotics</kwd><kwd>bacterial resistance</kwd><kwd>mycobacteria</kwd><kwd>tuberculosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>антибиотики</kwd><kwd>бактериальная устойчивость</kwd><kwd>микобактерии</kwd><kwd>туберкулез</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the Russian Science Foundation (grant 21-45-00018).</funding-statement><funding-statement xml:lang="ru">Исследование выполнено за счет гранта  Российского научного фонда (проект № 21-45-00018).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Salari N, Kanjoori AH, Hosseinian-Far A, Hasheminezhad R, Mansouri K, Mohammadi M.
