Нейротрофин-3 (NT-3), как и другие белки семейства нейротрофинов, играет важную роль в поддержании гомеостаза нервной системы, а нарушения его сигналинга ассоциированы с широким спектром неврологических и психических заболеваний.

Neurotrophin-3 (NT-3), like other proteins of the neurotrophin family, plays an important role in maintaining the homeostasis of the nervous system, and disorders of its signaling are associated with a wide range of neurological and psychiatric diseases. It is possible to overcome the limitations of the clinical use of NT-3 (low bioavailability, risk of side effects) by creating pharmacologically suitable low molecular weight mimetics.</p></sec><sec><title>Purpose</title><p>Purpose. To design and synthesize a new potential dipeptide mimetic of the 4th loop of NT-3 hexamethylenediamide &lt;i&gt;bis-(N&lt;/i&gt;-monoglutaryl-L-asparaginyl-L-asparagine), and to synthesize its enantiomer, in order to study their biological activity and identify its specificity.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The compounds were obtained by classical peptide synthesis methods in solution using the Boc strategy of protective groups and the method of activated pentafluorophenyl esters. The structure and diastereomeric purity of the target peptides and intermediates were established using one-dimensional 1Н, 13С and two-dimensional NMR spectroscopy. Chromatographic homogeneity was determined using TLC and RP HPLC. The target dipeptides were characterized by the specific optical rotation angle ([α]D).</p></sec><sec><title>Results</title><p>Results. A seven-step synthesis scheme for the L,L- and D,D-enantiomers of hexamethylenediamide bis-(N-monoglutaryl-asparaginyl-asparagine) (GTS-304LL, GTS-304DD) was proposed. The target dipeptides were obtained using this scheme with an overall yield of 37–38 % and a chromatographic purity of 97–99 %.</p></sec><sec><title>Conclusions</title><p>Conclusions. New substituted asparagine-containing dipeptides, potential neurotrophin-3 mimetics, were obtained. The compounds were characterized for further study of their biological activity.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейротрофин-3</kwd><kwd>миметик</kwd><kwd>дипептид</kwd><kwd>ГТС-304LL</kwd><kwd>ГТС-304DD</kwd><kwd>пептидный синтез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neurotrophin-3</kwd><kwd>mimetic</kwd><kwd>dipeptide</kwd><kwd>GTS-304LL</kwd><kwd>GTS-304DD</kwd><kwd>peptide synthesis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации (FGFG-2025-0008).</funding-statement><funding-statement xml:lang="en">This work was conducted under the government contract of the Ministry of Science and Higher Education of the Russian Federation (FGFG-2025-0008).</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">Skaper SD.
