Фармакологические эффекты орнитина обусловлены, прежде всего, участием в нейтрализации аммиака и в метаболизме аминокислот. Для уточнения механизмов действия орнитина был проведён хемореактомный анализ орнитина аспартата в сравнении с S-адеметионином (S-АМ) и урсодезоксихолевой кислотой (УДХК). Методы. Были оценены воздействия исследованных веществ на обмен уратов (производных мочевой кислоты), вазоактивность, структуру сосудов и на цитопротекцию методом хемореактомного анализа. Результаты. Установлено, что снижение уровней уратов в крови связано с ингибированием орнитином уратного транспортёра URAT1 (орнитин – IC50 = 65 нМ, S-АМ – 1060 нМ, УДХК – 94 нМ) и ксантиноксидазы (орнитин – IC50 = 910 нМ, остальные молекулы IC50 = 9655–11040 нМ). Среди исследованных молекул орнитин отличался наиболее выраженными вазодилаторными свойствами (связанными, вероятно, с ингибированием адренорецепторов: Kd = 35 нМ, другие молекулы – 1108–1428 нМ). Наибольшая антидислипидемическая активность была показана также для орнитина (9,4 %) и S-АМ (10,2 %), наименьшая – для УДХК (4,6 %). Антидислипидемический эффект орнитина связан с ингибированием эндотелиальной липазы (IC50 = 258 нМ для орнитина). Цитопротекторные эффекты орнитина ассоциированы с усилением синтеза глутатиона, снижением глутаматергической активности нейронов в условиях глутаматного стресса, ингибированием простагландин D-синтазы и снижением интенсивности острого лимфоцитарного воспаления без иммуносупрессии.Вывод. Таким образом, результаты хемореактомного анализа орнитина указывают на существенное расширение спектра фармакологических эффектов орнитина, включающий не только гепатопроекцию, но и кардиопротекцию и нефропротекцию</p></abstract><trans-abstract xml:lang="en"><p>Purpose of the study. The pharmacological effects of ornithine are primarily due to its participation in the neutralization of ammonia and in the metabolism of amino acids. To clarify the mechanisms of action of ornithine, a chemoreactom analysis of ornithine aspartate was performed in comparison with S-ademetionine (S-AM) and ursodeoxycholic acid (UDCA). Methods. The effects of the investigated substances on the metabolism of urates (derivatives of uric acid), vasoactivity, vascular structure and cytoprotection were assessed by the method of chemoreactome analysis. Results. It was found that a decrease in blood urate levels is associated with inhibition by ornithine of the urate transporter URAT1 (ornithine – IC50 = 65 nM, S-AM – 1060 nM, UDCA – 94 nM) and xanthine oxidase (ornithine – IC50 = 910 nM, other molecules IC50 = 9655-11040 nM). Among the studied molecules, ornithine was distinguished by the most pronounced vasodilatory properties (probably associated with inhibition of adrenergic receptors: Kd = 35 nM, other molecules – 1108-1428 nM). The highest antidyslipidemic activity was also shown for ornithine (9.4 %) and S-AM (10.2 %), the lowest for UDCA (4.6 %). The antidyslipidemic effect of ornithine is associated with inhibition of endothelial lipase (IC50 = 258 nM for ornithine). The cytoprotective effects of ornithine are associated with an increase in glutathione synthesis, a decrease in the glutamatergic activity of neurons under conditions of glutamate stress, inhibition of prostaglandin D-synthase, and a decrease in the intensity of acute lymphocytic inflammation without immunosuppression. Conclusion. Thus, the results of the ornithine chemoreactom analysis indicate a significant expansion of the spectrum of the pharmacological effects of ornithine, including not only hepatoprotection, but also cardioprotection and nephroprotection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>орнитина аспартат</kwd><kwd>урсодезоксихолевая кислота</kwd><kwd>S-адеметионин</kwd><kwd>фармакология</kwd><kwd>гепатопротекция</kwd><kwd>хеморектомный анализ</kwd><kwd>Гепа-Мерц</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ornithine aspartate</kwd><kwd>ursodeoxycholic acid</kwd><kwd>S-ademetionine</kwd><kwd>pharmacology</kwd><kwd>hepatoprotection</kwd><kwd>chemoreаctome analysis</kwd><kwd>HepaMertz</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">«Исследование выполнено за счет гранта Российского научного фонда (проект № 20- 12-00175)»</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">Громова О.А., Торшин И.Ю., Лазебник Л.Б., Максимов В.А.
