С целью расширения библиотеки биоактивных соединений, содержащих 1,3-диоксациклановый фрагмент, осуществлен синтез производных 5-ацил-5-изопропил-1,3-диоксана – 1-(5-изопропил-1,3-диоксан-5-ил)этанола и (1-(5-изопропил-1,3-диоксан-5-ил)этилфенилкарбамата. Изучено влияние функционально 2,2,4-тризамещенных 1,3-диоксоланов и синтезированных соединений, содержащих 1,3-диоксановый фрагмент, на рост штаммов грамотрицательных и грамположительных бактерий, низших грибов Candida albicans. Исследования структуры и активности показали, что 2-метил-2-этил-4-хлорметил-1,3-диоксолан, содержащий хлорметильную группу, обладает противомикробным действием в отношении грамположительных и грамотрицательных тест-культур и слабой противогрибковой активностью (минимальная ингибирующая концентрация 100 мкг/мл) в отношении более низких грибов Candida Albicans. 1-(5-Изопропил-1,3-диоксан-5-ил)этанол проявляет противогрибковую активность (минимальная ингибирующая концентрация 2 мкг/мл) и резко снижает антимикробную активность против Klebsiella pneumonia, Staphylococcus aureus, Enterobacter aerogenes (минимальная ингибирующая концентрация 100 мкг/мл), в отличие от сходного по строению 2-метил-2-этил-4-гидроксиметил-1,3-диоксолана, не проявившего аналогичных свойств. 5-Ацил-5-изопропил-1,3-диоксан, содержащий в структуре карбонильную группу, проявил антимикробную активность (минимальная ингибирующая концентрация 25 мкг/мл) в отношении грамотрицательных тест-культур, за исключением Pseudomonas aeruginosa. Гетероциклы (2-метил-2-этил-4-хлорметил-, 2-изобутил-2,4-диметил-, 2-метил-2-изобутил-4-хлорметил- и 2-метил-2-изобутил-4-гидроксиметил-1,3-диоксоланы) в концентрациях до 100 мкг/мл не ингибировали жизнедеятельность изученных бактерий и низших грибов. Полученные результаты показывают перспективность продолжения поиска новых антимикробных и противогрибковых препаратов ряда 1,3-диоксациклоалканов, структура которых принципиально отличается от известных антибактериальных препаратов.</p></abstract><trans-abstract xml:lang="en"><p>One of the directions in the development of organic chemistry is the synthesis of biologically active compounds, including those with bactericidal activity, based on available petrochemical raw materials. In order to expand the library of bioactive compounds containing a 1,3-dioxacyclane fragment, the synthesis of derivatives of 5-acyl-5-isopropyl-1,3-dioxane – 1-(5-isopropyl-1,3-dioxane-5-yl)ethanol and (5-isopropyl-1,3-dioxane-5-yl)ethyl phenyl carbamate was carried out. The effect of synthesized compounds containing a 1,3-dioxacyclane fragment on the growth of strains of gram-negative and gram-positive bacteria, lower fungi Candida albicans was studied. It was found that 2-methyl-2-ethyl-4-chloromethyl-1,3-dioxolane, containing a chloromethyl group, has an antimicrobial effect against gram-positive and gram-negative test cultures and weak antifungal activity (minimum inhibitory concentration is 100 μg/mL) against lower fungi Candida albicans. 1-(5-Isopropyl-1,3-dioxan-5-yl)ethanol exhibits antifungal activity (minimum inhibitory concentration is 2 μg/mL) and sharply reduces antimicrobial activity against Klebsiella pneumonia, Staphylococcus aureus, Enterobacter aerogenes (minimum inhibitory concentration is 100 μg/mL), in contrast to the structurally similar 2-methyl-2-ethyl-4-hydroxymethyl-1,3-dioxolane, which did not show similar properties. 5-Acyl-5-isopropyl-1,3-dioxane, containing a carbonyl group in its structure, showed antimicrobial activity (minimum inhibitory concentration is 25 μg/mL) against gram-negative test cultures, with the exception of Pseudomonas aeruginosa. Heterocycles (2-methyl-2-ethyl-4-chloromethyl-, 2-isobutyl-2,4-dimethyl-, 2-methyl-2-isobutyl-4-chloromethyl- and 2-methyl-2-isobutyl-4-hydroxymethyl-1,3-dioxolane) at concentrations up to 100 μg/mL did not inhibit the vital activity of the studied bacteria and lower fungi. The results obtained show the prospect of continuing the search for new antimicrobial and antifungal drugs of the series of 1,3-dioxacycloalkanes, the structure of which is fundamentally different from the known antibacterial drugs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиолы</kwd><kwd>конденсация</kwd><kwd>1</kwd><kwd>3-диоксациклоалканы</kwd><kwd>противомикробная активность</kwd><kwd>противогрибковое действие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyols</kwd><kwd>condensation</kwd><kwd>1</kwd><kwd>3-dioxacycloalkanes</kwd><kwd>antimicrobial activity</kwd><kwd>antifungal activity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках госзадания Минобрнауки России в сфере научной деятельности FEUR-2023-0006 «Разработка и создание малотоннажных продуктов и реагентов (ингибиторы коррозии и солеотложения, антиоксиданты, биоциды, присадки и др.) для процессов нефтегазохимии и очистки водных сред от загрязнений, замещающих импортные вещества и материалы.
