Изучить острую токсичность, эндотелио- и кардиопротективные свойства фенольных и тиофенольных производных 2Н-имидазолов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование выполнено на белых лабораторных мышах-самках линии BALB/c (n=57) и на мышах-самцах линии C57Bl/6 (n=66). Исследование острой токсичности проводилась по межгосударственному стандарту ГОСТ 32644-2014 с гистологической оценкой внутренних органов. Эндотелиальную дисфункцию моделировали при помощи 7-дневного внутрибрюшинного введения N-нитро-L-аргинин-метиловый эфира (L-NAME). Исследуемые малые молекулы вводились внутрижелудочно с помощью зонда. Для оценки эндотелиопротективного действия оценивали уровни систолического и диастолического артериального давления, а также коэффициент эндотелиальной дисфункции, для кардиопротективного эффекта — результаты нагрузочных проб на миокард.</p></sec><sec><title>Результаты</title><p>Результаты. Изучение острой токсичности исследуемых малых молекул позволило отнести их к 4 и 5 классу. Введение мышам соединений 1(a–d) и 2(a–c) в дозе, равной 1/10 от LD50, привело к изменению уровня артериального давления и восстановлению динамики фармакологических проб в ответ на введение ацетилхолина и нитропруссида натрия. Статистически значимую эндотелиопротективную активность в 3 дозах (1/10, 1/50 и 1/100 от LD50) показали молекулы 1b и 2c. Также данные соединения-хиты продемонстрировали кардиопротективные эффекты, регистрируемые восстановлением функциональных возможностей миокарда в ответ на нагрузку в объёме и в пробе на адренореактивность, и в меньшей степени — при проведении нагрузки сопротивлением.</p></sec><sec><title>Заключение</title><p>Заключение. Исследуемые соединения имеют низкую токсичность и обладают эндотелио- и кардиопротективным действием. Данное исследование может поспособствовать формированию представления о дальнейших направлениях в изучении фармакологической активности данных молекул из группы фенольных и тиофенольных производных 2Н-имидазолов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim</title><p>The aim. To study the acute toxicity, endothelial- and cardioprotective properties of phenolic and thiophenolic derivatives of 2H-imidazoles.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was performed on white laboratory female BALB/c mice (n=57) and male C57Bl/6 mice (n=66). Acute toxicity was assessed according to the interstate standard GOST 32644-2014 with histological evaluation of internal organs. Endothelial dysfunction was modeled by 7-day intraperitoneal administration of N-nitro-L-arginine methyl ester (L-NAME). The studied small molecules were administered intragastrically using a probe. To assess the endothelial protective effect, the levels of systolic and diastolic blood pressure were evaluated, as well as the coefficient of endothelial dysfunction; for the cardioprotective effect, the results of stress tests on the myocardium were evaluated.</p></sec><sec><title>Results</title><p>Results. The study of acute toxicity of the studied small molecules allowed us to classify them as class 4 and 5. The administration of compounds 1(a–d) and 2(a–c) to mice at a dose equal to 1/10 of LD50 led to changes in blood pressure and restoration of the dynamics of pharmacological tests in response to the administration of acetylcholine and sodium nitroprusside. Molecules 1b and 2c showed statistically significant endothelial protective activity in 3 doses (1/10, 1/50 and 1/100 of LD50). Also, these hit compounds demonstrated cardioprotective effects, recorded by the restoration of the functional capabilities of the myocardium in response to load and in the adrenoreactivity test, and to a lesser extent, during resistance exercise.</p></sec><sec><title>Conclusion</title><p>Conclusion. The studied compounds have low toxicity and have endothelial- and cardioprotective effects. This study may contribute to the formation of an idea about further directions in the study of the pharmacological activity of these molecules from the group of phenolic and thiophenolic derivatives of 2H-imidazoles.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>азагетероциклические соединения</kwd><kwd>малые молекулы</kwd><kwd>эндотелиальная дисфункция</kwd><kwd>имидазолы</kwd><kwd>фенолы</kwd><kwd>тиофенолы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>azaheterocyclic compounds</kwd><kwd>small molecules</kwd><kwd>endothelial dysfunction</kwd><kwd>imidazoles</kwd><kwd>phenols</kwd><kwd>thiophenols</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Российского научного фонда в рамках научного проекта 23-63-10011 (Доступно по ссылке: https://www.rscf.ru/project/23-63-10011/).</funding-statement><funding-statement xml:lang="en">This research was financially supported by the Russian Science Foundation, project 23-63-10011, https://www.rscf.ru/en/project/23-63-10011/.</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">Su J.B.
