Нейропептид цикло-пролилглицин (ЦПГ) – эндогенный дипептидный аналог ноотропа пирацетама. Экспериментально показано, что ЦПГ (сконструирован и синтезирован в ФГБНУ «ФИЦ оригинальных и перспективных биомедицинских и фармацевтических технологий») обладает спектром фармакологических эффектов, характерным для пирацетама. В исследованиях, направленных на изучение механизмов действия ЦПГ, было установлено, что глутаматные AMPA-рецепторы и нейротрофиновые Trk-рецепторы вовлечены в анксиолитический, нейропротекторный и антигипоксический эффекты ЦПГ. Однако механизм ноотропного действия ЦПГ не изучен.</p></sec><sec><title>Цель работы</title><p>Цель работы. Проверить гипотезу о вовлечённости Trk-рецепторов в ноотропный эффект ЦПГ на модели амнезии у мышей, вызванной введением скополамина.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Ноотропную активность ЦПГ (1 мг/кг, в/б) изучали на модели амнезии у мышей, вызванной скополамином (0,75 мг/кг, подкожно). Использовали метод фармакологического ингибиторного анализа с применением блокатора Trk-рецепторов К252а (5 мкг/кг, в/б). Выраженность амнезии оценивали в тесте «Распознавание нового объекта (РНО)».</p></sec><sec><title>Результаты</title><p>Результаты. Было установлено, что скополамин нарушает распознавание нового объекта у мышей в тесте РНО. ЦПГ препятствует развитию амнезии, вызванной скополамином, а блокатор Trk-рецепторов К252а блокирует этот эффект.</p></sec><sec><title>Выводы</title><p>Выводы. Trk-рецепторы вовлечены в ноотропный эффект нейропептида ЦПГ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The neuropeptide cycloprolylglycine (CPG) is an endogenous dipeptide analogue of the nootropic piracetam. It has been experimentally shown that CPG (designed and synthesized at the Federal State Budgetary Scientific Institution «Federal Research Center of Original and Promising Biomedical and Pharmaceutical Technologies») has a spectrum of pharmacological effects characteristic of piracetam. In studies aimed at studying the mechanisms of action of CPG, it was found that glutamate AMPA receptors and neutrophin Trk receptors are involved in the anxiolytic, neuroprotective and antihypoxic effects of CPG. However, the mechanism of nootropic action of CPG has not been studied.</p></sec><sec><title>Objective</title><p>Objective. To test the hypothesis about the involvement of Trk receptors in the nootropic effect of CPG in a model of amnesia in mice induced by the administration of scopolamine.</p></sec><sec><title>Material and methods</title><p>Material and methods. The nootropic activity of CPG (1 mg/kg, i.p.) was studied in a model of amnesia in mice induced by scopolamine (0.75 mg/kg, subcutaneously). A pharmacological inhibitory assay was used with the Trk receptor blocker K252a (5 μg/kg, i.p.). The severity of amnesia was assessed using the Novel Object Recognition (NOR) test.</p></sec><sec><title>Results</title><p>Results. Scopolamine was found to impair novel object recognition in mice in the NOR test. CPG prevents the development of amnesia induced by scopolamine, and Trk receptor blocker K252a blocks this effect.</p></sec><sec><title>Conclusion</title><p>Conclusion. Trk receptors are involved in the nootropic effect of the neuropeptide CPG.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цикло-пролилглицин</kwd><kwd>ноотропная активность</kwd><kwd>скополаминовая амнезия</kwd><kwd>распознавание нового объекта</kwd><kwd>К252а</kwd><kwd>Trk</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cyclo-prolylglycine</kwd><kwd>nootropic activity</kwd><kwd>scopolamine amnesia</kwd><kwd>novel object recognition</kwd><kwd>К252а</kwd><kwd>Trk</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации (тема FGFG-2022-0005).</funding-statement><funding-statement xml:lang="en">This study was conducted under the government contract of the Ministry of Science and Higher Education of the Russian Federation (Project FGFG-2022-0005).</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">Gudasheva TA, Boyko SS, Akparov VKh, et al.
