Болезнь Альцгеймера (БА) – терминальная форма деменции, лечение которой представляет собой значимую медицинскую проблему, что требует разработки новых лекарственных средств для коррекции данного состояния. Одной из таких перспективных групп могут являться антиоксиданты.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: в условиях экспериментальной БА оценить антиоксидантные свойства монокарбонильных аналогов куркумина.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. БА моделировали у крыс Wistar обоего пола путем введения агрегатов Аβ1-42 в СА1 часть гиппокампа животных. Анализируемые соединения (1E, 4E)-1,5-бис (3,4,5-триметоксифенил) пента-1,4-диен-3-он и (1E, 4E)-1,5-бис (2,4,6-триметоксифенил) пента-1,4-диен-3-он в дозе 20 мг/кг перорально и донепезил в дозе 50 мг/кг перорально вводили на протяжении 30 дней с момента операции. По истечении указанного времени у крыс в ткани гиппокампа оценивали изменение активности ферментов эндогенной антиоксидантной защиты: супероксиддисмутазы, глутатионпероксидазы и каталазы, определяли изменение концентрации митохондриального пероксида водорода и активных продуктов, реагирующих с 2-тиобарбитуровой кислотой.</p></sec><sec><title>Результаты</title><p>Результаты. В ходе исследования было показано, что применение анализируемых соединений и препарата сравнения способствовало повышению активности антиоксидантных ферментов в ткани гиппокампа у крыс, как у самок, так и самцов. При этом у животных, которым вводили (1E, 4E)-1,5-бис (3,4,5-триметоксифенил) пента-1,4-диен-3-он и (1E, 4E)-1,5-бис (2,4,6-триметоксифенил) пента-1,4-диен-3-он, активность супероксиддисмутазы достоверно (p &lt; 0,05) увеличилась по отношению к группе животных получавших донепезил. На фоне введения анализируемых веществ было установлено снижение концентрации митохондриального пероксида водорода и активных продуктов, реагирующих с 2-тиобарбитуровой кислотой, которая была достоверно (p &lt; 0,05) меньше, чем в случае применения донепезила.</p></sec><sec><title>Заключение</title><p>Заключение. Изучаемые монокарбонильные аналоги куркумина оказывают антиоксидантное действие в условиях экспериментальной БА, превосходя при этом препарат сравнения донепезил. На основании полученных данных можно предполагать актуальность дальнейших исследований, анализирующих монокарбонильные куркуминоиды в качестве средств патогенетической терапии БА.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Alzheimer’s disease is a terminal form of dementia, the treatment of which is a significant medical problem, which requires the development of new drugs to correct this condition. Antioxidants may be one of such promising groups.</p></sec><sec><title>Aim</title><p>Aim: To assess the antioxidant properties of monocarbonyl analogues of curcumin in the conditions of experimental Alzheimer’s disease.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. Alzheimer’s disease was modeled in Wistar rats of both genders by injection Aß1-42 aggregates into the CA1 part of the hippocampus of animals. The analyzed compounds are (1E, 4E)-1.5-bis (3,4,5-trimethoxyphenyl) penta1,4-diene-3-one and (1E, 4E)-1.5-bis (2,4,6-trimethoxyphenyl) penta-1,4-diene-3-one at a dose of 20 mg/kg orally and the reference donepezil at a dose of 50 mg / kg, orally was administered for 30 days from the moment of surgery. After this time, changes in the activity of endogenous antioxidant defense enzymes: superoxide dismutase, glutathione peroxidase and catalase were evaluated in rats in hippocampal tissue, and changes in the concentration of mitochondrial hydrogen peroxide and active products reacting with 2-thiobarbituric acid were also determined.</p></sec><sec><title>Results</title><p>Results. During the study, it was shown that the use of the analyzed compounds and the reference contributed to an increase in the activity of antioxidant enzymes in hippocampal tissue in rats. At the same time, in animals (both sexes) treated by (1E, 4E)-1.5-bis (3,4,5-trimethoxyphenyl) penta-1,4-diene-3-one and (1E, 4E)-1.5-bis (2,4,6-trimethoxyphenyl) penta-1,4-diene-3-one, the activity of superoxide dismutase was higher (p &lt; 0.05), than in animals treated by donepezil. Also, administration of the analyzed substances, a decrease in the concentration of mitochondrial hydrogen peroxide and active products reacting with 2-thiobarbituric acid was found, which was significantly (p &lt; 0.05) lower when donepezil were administered.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study showed that the monocarbonyl analogues of curcumin have an antioxidant effect in the conditions of experimental Alzheimer’s disease, while surpassing the reference donepezil. Based on the obtained data, it is reasonable to assume the relevance of further studies analyzing monocarbonyl curcuminoids as a remedies of pathogenetic therapy of Alzheimer’s disease.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Альцгеймера</kwd><kwd>окислительный стресс</kwd><kwd>нейропротекция</kwd><kwd>куркуминоиды</kwd><kwd>крысы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Alzheimer’s disease</kwd><kwd>oxidative stress neuroprotection</kwd><kwd>curcuminoids</kwd><kwd>rats</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dewanjee S., Chakraborty P., Bhattacharya H., Chacko L., Singh B., Chaudhary A. et al.
