Гипоксия представляет собой нарушение окислительных процессов в тканях, возникающие при недостаточном поступлении в них кислорода или при нарушении его утилизации в процессе биологического окисления. Хроническое гипоксическое повреждение играет важную роль в возникновении и развитии различных заболеваний, что обуславливает необходимость синтеза новых соединений, обладающих антигипоксической активностью.</p></sec><sec><title>Цель</title><p>Цель. Целью данного исследования является синтез и исследование антигипоксической активности 2-арил-7,7-диметил-5-оксо-5,6,7,8-тетрагидрохинолин-4-карбоновых кислот и продуктов их реакции с замещенными гидразинами.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. 2-Арил-7,7-диметил-5-оксо-5,6,7,8-тетрагидрохинолин-4-карбоновые кислоты (I–VI) получены с высокими выходами в результате взаимодействия 4-ароил-2,4-диоксобутановых кислот с 3-амино-5,5-диметилциклогекс-2-еноном.</p><p>Взаимодействием 2-арил-7,7-диметил-5-оксо-5,6,7,8-тетрагидрохинолин-4-карбоновых кислот с бензил- и (2-фенилэтил)гидразинами получены 5-арил-2-бензил- и 2-(2-фенилэтил)-8,8-диметил-3,7,8,9-тетрагидро-2Н-пиридо[4,3,2-de]циннолин-3-оны (VII–XII). В результате было синтезировано 12 соединений. Изучение антигипоксической активности полученных соединений проводилось in vivo на модели нормобарической гипоксии с гиперкапнией.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Синтезированные соединения были исследованы на наличие антигипоксического действия. Наиболее выраженная антигипоксическая активность характерна для соединений VI и VIII, имеющих в пара-положении фенильного заместителя при С5 метоксигруппу и метильный радикал соответственно. Наличие хлора в структуре соединения III, фтора у соединения X и отсутствие заместителей (соединения I и VII) способствуют прогипоксическому действию. По результатам исследования как хинолинкарбоновые кислоты, так и пиридоциннолины являются потенциальными антигипоксантами.</p></sec><sec><title>Заключение</title><p>Заключение. Проведен сравнительный анализ антигипоксической активности синтезированных соединений, установлена взаимосвязь между их структурой и выраженностью действия, выявлены наиболее активные вещества.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Hypoxia is a violation of oxidative processes in tissues that occur when oxygen is insufficiently supplied to them or when its utilization is disrupted during biological oxidation. Chronic hypoxic damage plays an important role in the occurrence and development of various diseases, which necessitates the synthesis of new compounds with antihypoxic activity.</p></sec><sec><title>Aim</title><p>Aim. The purpose of this study is to synthesize and investigate the antihypoxic activity of 2-aryl-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydroquinoline-4-carboxylic acids and their reaction products with substituted hydrazines.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 2-Aryl-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydroquinoline-4-carboxylic acids (I–VI) were obtained with high yields as a result of the interaction of 4-aroyl-2,4-dioxobutane acids with 3-amino-5,5-dimethylcyclohex-2-enone. Interaction of 2-aryl-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydroquinoline-4-carboxylic acids with benzyl- and (2-phenylethyl)hydrazines 5-aryl-2-benzyl- and 2-(2-phenylethyl)-8,8-dimethyl-3,7,8,9-tetrahydro-2H-pyrido[4,3,2-de]cinnoline-3-ones (VII–XII) were obtained. As a result, 12 compounds were synthesized. The study of the antihypoxic activity of the obtained compounds was carried out in vivo on a model of normobaric hypoxia with hypercapnia.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The synthesized compounds were tested for the presence of antihypoxic action. The most pronounced antihypoxic activity is characteristic of compounds VI and VIII, which have a methoxy group and a methyl radical in the para-position of the phenyl substituent at C5, respectively. The presence of chlorine in the structure of compound III, fluorine in compound X and the absence of substituents (compounds I and VII) contribute to the prohypoxic effect. According to the results of the study, both quinolincarboxylic acids and pyridocinnolines are potential antihypoxants.</p></sec><sec><title>Conclusion</title><p>Conclusion. A comparative analysis of the antihypoxic activity of the synthesized compounds was carried out, the relationship between their structure and severity of action was established, the most active substances were identified.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>хинолинкарбоновые кислоты</kwd><kwd>пиридоциннолины</kwd><kwd>антигипоксическая активность</kwd><kwd>гипоксия</kwd><kwd>гетероцикл</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quinolinecarboxylic acids</kwd><kwd>pyridocinonnolines</kwd><kwd>antihypoxic activity</kwd><kwd>hypoxia</kwd><kwd>heterocycle</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Пермского научно-образовательного центра «Рациональное недропользование» 2022 г.</funding-statement><funding-statement xml:lang="en">The study was carried out with the financial support of the Perm Scientific and Educational Center "Rational Subsoil Use", 2023.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Черешнев В.
