We investigated the effects of new peptide compounds, β-casomorphin-7 and colostrinin, in two complementary AD models in rats (with injection of β-amyloid into the nucleus basalis of Meynert and injection of streptozocin in the ventricles of the brain). Peptides were injected intranasally within 10 days after the onset of AD symptoms induced by neurotoxins. Injection of β-casomorphin-7 and colostrinin had similar effect on the behavior and cognitive function of rats with both amyloid and streptozocin AD model: there was statistically significant increase in locomotor activity and orienting responses, as well as improvement of animals’ cognitive functions. Colostrinin had stronger positive effect on the behavior of rats with induced AD, whereas β-casomorphin-7 had an effect on both sham-operated and model animals, which is indicative of the general neurotropic potential of this peptide. The proposed experimental approaches improve the capabilitiesof investigation of novel biologically active compounds aimed at prevention and treatment of neurodegenerative diseases.</p></abstract><trans-abstract xml:lang="ru"><p>Разработка новых подходов к лечению болезни Альцгеймера (БА) остается актуальной проблемой современной неврологии в связи с ее высокой распространенностью в популяции и тяжелой необратимой инвалидизацией, которой она сопровождается. Нами на двух взаимодополняющих моделях БА у крыс (с введением β β-амилоида в ядра Мейнерта и с введением стрептозоцина в желудочки мозга) исследованы эффекты новых пептидных соединений – β-казоморфина-7 и колостринина. Введение пептидов осуществляли интраназально в течение 10 дней после развития симптомов БА, индуцированного нейротоксинами. Введение β-казоморфина-7 и колостринина оказало сходное действие на поведение и когнитивные функции крыс как с β-амилоидной, так и со стрептозоциновой моделью БА: наблюдалось статистически значимое усиление двигательной активности и ориентировочных реакций, а также улучшение когнитивных функций животных. Колостринин оказывал более выраженный положительный эффект на поведение крыс с индуцированной БА, тогда как β-казоморфин-7 действовал и на ложнооперированных и на модельных животных, что свидетельствует об общем нейротропном потенциале данного пептида. Предложенные экспериментальные подходы расширяют возможности изучения новых биологически активных веществ, направленных на профилактику и лечение нейродегенеративных заболеваний.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Alzheimer's disease</kwd><kwd>β-amyloid</kwd><kwd>streptozocin, neuroprotection, peptides</kwd><kwd>β-casomorphin-7</kwd><kwd>colostrinin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>болезнь Альцгеймера</kwd><kwd>β-амилоид</kwd><kwd>стрептозоцин</kwd><kwd>нейропротекция</kwd><kwd>пептиды</kwd><kwd>β-казоморфин-7</kwd><kwd>колостринин</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Дубынин В.А., Каменский А.А.
