Throughout the entire period of its study, no remedies have been found that would be effective in treating \u2013 or at least significantly slowing \u2013 the pathological process, while being sufficiently safe. In this regard, significant attention is paid to the development and application of natural peptide drugs lacking side effects. The present study assessed the effect of the known neuroprotective peptide Semax and its derivative on the behavioral characteristics and development of amyloidosis in transgenic APPswe\/PS1dE9\/Blg mice acting as a model of Alzheimer\u2019s disease. The open field, novel object recognition, and Barnes maze tests demonstrated that both Semax and its derivative improved cognitive functions in mice. Histological examination showed that these peptides reduced the number of amyloid inclusions in the cortex and hippocampus of the animals\u2019 brains. These findings demonstrate the high potential of Semax and its derivatives when used to develop therapeutic and corrective strategies for Alzheimer\u2019s disease.<\/jats:p>","DOI":"10.32607\/actanaturae.27808","type":"journal-article","created":{"date-parts":[[2025,12,23]],"date-time":"2025-12-23T09:46:26Z","timestamp":1766483186000},"page":"110-120","source":"Crossref","is-referenced-by-count":2,"title":["The potential of the peptide drug Semax and Its derivative for correcting pathological impairments in the animal model of Alzheimer\u2019s disease"],"prefix":"10.32607","volume":"17","author":[{"given":"Alexandra I.","family":"Radchenko","sequence":"additional","affiliation":[{"name":"Belgorod State National Research University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena V.","family":"Kuzubova","sequence":"additional","affiliation":[{"name":"Belgorod State National Research University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alina A.","family":"Apostol","sequence":"additional","affiliation":[{"name":"Belgorod State National Research University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladimir A.","family":"Mitkevich","sequence":"additional","affiliation":[{"name":"Engelhardt Institute of Molecular Biology, Russian Academy of Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liudmila A.","family":"Andreeva","sequence":"additional","affiliation":[{"name":"National Research Center \u201cKurchatov Institute\u201d"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana A.","family":"Limborskaya","sequence":"additional","affiliation":[{"name":"National Research Center \u201cKurchatov Institute\u201d"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu.
