Закусова как топологический аналог классического ноотропа пирацетама и в дальнейшем идентифицирован как эндогенное соединение. Ранее ноотропный эффект ЦПГ был выявлен на модели ретроградной амнезии у крыс, вызванной электрошоком, в тесте условного рефлекса пассивного избегания (УРПИ).</p><sec><title>Цель</title><p>Цель. Цель настоящего исследования — изучить ноотропный эффект ЦПГ в более физиологичных условиях в отсутствие сильных стрессирующих факторов.</p></sec><sec><title>Методы</title><p>Методы. Амнезию у крыс моделировали внутрибрюшинным (в/б) введением скополамина в дозе 2 мг/кг. ЦПГ вводили в/б в дозах 0,1 и 1,0 мг/кг через 15 мин после скополамина. Кратковременную и долговременную память регистрировали в тесте распознавания нового объекта.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что введение скополамина нарушало только долговременную память крыс. ЦПГ в дозе 0,1 мг/кг практически полностью противодействовал этому нарушению. Сам ЦПГ не влиял на память крыс в обеих изученных дозах.</p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, ЦПГ проявляет ноотропную активность не только в аверсивных условиях теста УРПИ и электрошоковой амнезии, но и в нейтральной ситуации в тесте распознавания нового объекта, когда амнезия была вызвана введением скополамина.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Cyclo-L-prolylglycine (CPG) was designed and synthesized at the V.V. Zakusov as a topological analogue of the classical nootrop piracetam and was further identiﬁed as an endogenous compound. Previously, the nootropic eﬀect of CPG was revealed in a model of retrograde amnesia in rats induced by electroconvulsive shock in the passive avoidance test (PAT).</p></sec><sec><title>Objective</title><p>Objective. The aim of the present study was to investigate the nootropic eﬀect of CPG under more physiological conditions in the absence of strong stressors.</p></sec><sec><title>Methods</title><p>Methods. Amnesia in rats was modeled by intraperitoneal (ip) administration of scopolamine at a dose of 2 mg/kg. CPG was administered ip at doses of 0.1 and 1.0 mg/kg 15 minutes after scopolamine. Short- and long-term memory were recorded in the novel object recognition test.</p></sec><sec><title>Results</title><p>Results. It was found that scopolamine disrupted only the long-term memory of rats. CPG at a dose of 0.1 mg/ kg almost completely counteracted this impairment. CPG by itself had no eﬀect on memory at both doses studied.</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, CPG exhibits nootropic activity not only in the aversive conditions of the PAT and electroconvulsive shock-induced amnesia, but also in the neutral situation in the novel object recognition test, when the amnesia was caused by the administration of scopolamine.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>циклопролилглицин</kwd><kwd>ноотропная активность</kwd><kwd>скополаминовая амнезия</kwd><kwd>тест распознавания нового объекта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cycloprolylglycine</kwd><kwd>nootropic activity</kwd><kwd>scopolamine amnesia</kwd><kwd>novel object recognition test</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">Гудашева Т.А., Островская Р.У., Максимова Ф.В. и др.
