Известно, что количество запусков докинга с AutoDock 4 играет важную роль в достоверности получаемых результатов. Чем больше количество запусков, тем больше достоверных результатов докинга Однако точно не известно, как наиболее оптимально работает докинг с AutoDock 4. Это исследование направлено на определение влияния количества запусков процесса докинга в AutoDock 4 на достоверность результатов.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В качестве метода исследования использовали процесс редокинга с AutoDock 4.2.6. Используемый рецептор представляет собой рецептор эстрогена с эталонным лигандом эстрадиола (PDB ID 1GWR). Варьировали количество прогонов от 10 до 100, кратные 10. Наблюдаемыми параметрами были RMSD, свободная энергия связывания, константы ингибирования, аминокислотные остатки и количество водородных связей.</p></sec><sec><title>Результаты</title><p>Результаты. Все эксперименты вырабатывают идентичную свободную энергию связи, где максимальная разница в константе ингибирования составляет всего 0,06 нМ. Наименьшее среднеквадратичное отклонение (RMSD) определяется количеством прогонов, равным 60, при значении среднеквадратичного отклонения, равного 0,942. Установлено, что между количеством прогонов и пространственным выравниванием (RMSD) нет линейной зависимости, так как коэффициент корреляции (R) равен 0,4607.</p></sec><sec><title>Заключение</title><p>Заключение. В целом, количество запусков не оказывает значительного вклада в достоверность результатов процесса докинга с AutoDock 4. Однако, эти результаты справедливы только с рецепторами, использованными в данном исследовании.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim</title><p>The aim. The number of runs in the docking process with AutoDock 4 is known to play an important role in the validity of the results obtained. The greater the number of runs it is often associated with the more valid docking results. However, it is not known exactly how the most ideal runs in the docking process with AutoDock 4. This study aims to determine the effect of the number of runs docking processes with AutoDock 4 on the validity of the docking results.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The method used is the redocking process with AutoDock 4.2.6. The receptor used is an estrogen receptor with ligand reference estradiol (PDB ID 1GWR). Variations were made on the number of runs from 10 to 100 in multiples of 10. The parameters observed were RMSD, free energy of binding, inhibition constants, amino acid residues, and the number of hydrogen bonds.</p></sec><sec><title>Results</title><p>Results. All experiments produce identical bond free energy, where the maximum difference in inhibition constant is only 0.06 nM. The lowest RMSD is indicated by the number of runs of 60, with a RMSD value of 0.942. There is no linear relationship between the number of runs and RMSD, with R in the linear equation of 0.4607.</p></sec><sec><title>Conclusion</title><p>Conclusion. Overall, the number of runs does not show a significant contribution to the validity of the results of docking with AutoDock 4. However, these results have only been proven with the receptors used.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>AutoDock 4</kwd><kwd>докинг</kwd><kwd>количество запусков</kwd><kwd>RMSD</kwd><kwd>вариация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>AutoDock 4</kwd><kwd>docking</kwd><kwd>number of runs</kwd><kwd>RMSD</kwd><kwd>variation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование не имело финансовой поддержки от сторонних орагнизаций.</funding-statement><funding-statement xml:lang="en">This study did not have any financial support from outside organizations</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">Ferreira L.G., Dos Santos R.N., Oliva G., Andricopulo A.D.
