   <abstract xml:lang="ru">
    <p>Методом теоретического конформационного анализа исследованы конформационные возможности молекул сойморфина-5 (Thr1-Pro2-Phe3-Val4-Val5-NH2), сойморфина-6 (Tyr1-Pro2-Phe3-Val4-Val5-Asn6-NH2) и сойморфина-7 (Tyr1-Pro2-Tyr3-Val4-Val5-Asn6-Ala7-NH2). Потенциальная функция системы выбрана в виде суммы невалентных, электростатических и торсионных взаимодействий и энергии водородных связей. Найдены низкоэнергетические конформации молекул сойморфина-5, сойморфина-6 и сойморфина-7, значения двугранных углов основных и боковых цепей аминокислотных остатков, входящих в состав молекул, оценена энергия внутри- и межостаточных взаимодействий. Показано, что пространственная структура молекул сойморфина-5, сойморфина-6 и сойморфина-7 представлена конформациями восьми шейпов пептидного скелета. Таким образом, пространную структуру молекул сойморфина-5, сойморфина-6 и сойморфина-7 можно представить восемью структурными типами. Можно предположить, что молекулы свои физиологические функции осуществляет в этих структурах. Сравнение низкоэнергетических структур сойморфинов показывают, что во всех молекулах первые четыре низкоэнергетические конформации являются представителями структурных типов efef, efee, efff, effe у сойморфина-5, effff, efeff, efffe, effee у сойморфина-6, efffff, efeffe, efffef, effeee у сойморфина-7. На основе этих структур можно предложить их искусственных аналогов для синтеза. Полученные результаты могут быть использованы для выяснения структурной и структурно-функциональной организации молекул сойморфинов.</p>

    <p>The conformational capabilities of soymorphine-5 (Thr1-Pro2-Phe3-Val4-Val5-NH2), soymorphine-6 (Tyr1-Pro2-Phe3-Val4-Val5-Asn6-NH2) and soymorphine-7 (Tyr1- Pro2-Tyr3-Val4-Val5-Asn6-Ala7-NH2) molecules have been studied by the method of theoretical conformational analysis. The potential function of the system is chosen as the sum of non-valence, electrostatic and torsion interactions and the energy of hydrogen bonds. The low-energy conformations of soymorphine-5, soymorphine-6 and soymorphine-7 molecules were found, the dihedral angles of the main and side chains of amino acid residues that make up the molecule were found, and the energy of intra- and interresidual interactions was estimated. Thus, the spatial structure of soymorphine-5, soymorphine-6 and soymorphine-7 molecules can be represented by eight structural types. It can be assumed that the molecules perform their physiological functions in these structures. Comparison of the low-energy structures of soymorphins shows that in all molecules the first four low-energy conformations are representatives of the structural types efef, efee, efff, effe for soymorphine-5, effff, efeff, efffe, effee for soymorphine-6, efffff, efeffe, efffef, effeee for soymorphine-6. soymorphine-7. On the basis of these structures, it is possible to propose their artificial analogues for synthesis. It was shown that the spatial structure of soymorphine-5, soymorphine-6 and soymorphine-7 molecules is represented by the conformations of eight shapes of the peptide skeleton. The results obtained can be used to elucidate the structural and structural-functional organization of soymorphine molecules.</p>
