Для устранения высокого уровня иммуноглобулинов класса G применяются специфические сорбенты. В качестве инструмента для теоретического поиска лигандов сорбентов для удаления IgG из биологических жидкостей может применяться молекулярный докинг. С помощью докинга проведено моделирование взаимодействий аминокислот с IgG. Исходя из результатов докинга, были выявлены активные аминокислоты и предложены возможные комбинации из них для создания дии трипептидных последовательностей. В результате расчетов было выявлено, что лучшими по энергии взаимодействия в ряду аминокислот обладают ароматические аминокислоты (Tyr, Trp, Phe), созданные на их основе дии трипептиды (Trp-DTyr, Phe-DTyr, Trp-Phe-DTyr, Phe-Trp-DTyr) имеют высокую энергию связывания к белкам IgG, а трипептиды (Trp-Phe-DTyr, Phe-Trp-DTyr) не только демонстрируют высокую энергию взаимодействия с общим IgG, но и могут быть разделены в своей активности относительно подклассов иммуноглобулинов класса G.</p></abstract><trans-abstract xml:lang="en"><p>Hyperproduction of immunoglobulin G (IgG) is a major pathogenic factor in autoimmune diseases. Specific sorbents are used to eliminate the high level of IgG. Molecular docking can be used as a tool for theoretical search for sorbent ligands for the IgG removal from biological fluids. Using docking, modeling of amino acid interactions with IgG ligands was performed. Based on the docking results, active amino acids were identified and possible combinations of them were proposed for the creation of diand tripeptide sequences. As a result, aromatic amino acids (Tyr, Trp, Phe), di-and tripeptides based on them (Trp-DTyr, Phe-DTyr, Trp-Phe-DTyr, Phe-Trp-DTyr) were found to have high activity for IgG proteins, and three peptides (Trp-Phe-DTyr, Phe-Trp-DTyr) not only show high activity to total IgG, but can also be divided in their activity relative to subclasses of class G immunoglobulins.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сорбция</kwd><kwd>сорбенты</kwd><kwd>иммуноглобулины</kwd><kwd>подклассы</kwd><kwd>белки</kwd><kwd>лиганды</kwd><kwd>пептиды</kwd><kwd>молекулярное моделирование</kwd><kwd>докинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sorption</kwd><kwd>sorbents</kwd><kwd>immunoglobulins</kwd><kwd>subclasses</kwd><kwd>proteins</kwd><kwd>ligands</kwd><kwd>peptides</kwd><kwd>molecular modeling</kwd><kwd>docking</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">Иммуносорбция в лечении дилатационной кардиомиопатии / К.
