В результате тестирования этой модели на двух наборах структурно разнородных молекул с использованием метрик регрессионной оценки MAE, MSE, R2 и R показано, что она сопоставима по предсказательной эффективности с оценочной функцией Vina программы молекулярного докинга QuickVina 2. При этом разработанная модель позволяет значительно ускорить процесс виртуального скрининга потенциальных лекарств, что является важным фактором при анализе молекулярных библиотек, включающих сотни тысяч и даже миллионы химических структур. В связи с этим предлагаемая модель может быть использована в качестве экспресс-метода для быстрого отбора в химических базах данных перспективных соединений с последующим предсказанием их положений в сайте связывания MmpL3 с помощью молекулярного докинга и исследованием стабильности комплексов лиганд/MmpL3 методами молекулярной динамики. Полученные результаты свидетельствуют о высокой эффективности разработанной модели и ее значительном потенциале для использования в виртуальном скрининге соединений-кандидатов, антибактериальное действие которых основано на ингибировании белка MmpL3 Mycobacterium tuberculosis – одной из приоритетных терапевтических мишеней для создания новых эффективных препаратов против лекарственно-устойчивого туберкулеза.</p></abstract><trans-abstract xml:lang="en"><p>A boosting-based ensemble machine learning model that utilizes molecular descriptors as input data has been developed to predict the values of binding free energy   of small-molecule compounds to the MmpL3 of Mycobacterium tuberculosis (Mtb), an essential mycolic acid and lipid transporter required for growth and cell viability. Testing this model on two large sets of structurally heterogeneous molecules via regression evaluation metrics MAE, MSE, R2, and R showed that it is comparable in predictive performance to the Vina scoring function of the QuickVina 2 molecular docking program, but allows one to significantly speed up the structure-based virtual screening, which is an important factor in the analysis of molecular libraries containing hundreds of thousands, and occasionally millions, of chemical structures. In this regard, the developed model can be used as an express method for the rapid selection of candidate compounds in chemical databases, followed by prediction of their poses in the MmpL3 binding site using molecular docking and a study of the stability of ligand/MmpL3 complexes via molecular dynamics methods. The results obtained demonstrate the high efficiency of the developed model and its significant potential for the use in virtual screening of candidate compounds with antibacterial action based on the inhibition of the MmpL3 protein of Mycobacterium tuberculosis, one of the priority therapeutic targets for the design of new effective therapeutics against drug-resistant tuberculosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прогностические модели</kwd><kwd>машинное обучение</kwd><kwd>бустинг</kwd><kwd>молекулярный докинг</kwd><kwd>виртуальный скрининг</kwd><kwd>Mycobacterium tuberculosis</kwd><kwd>MmpL3</kwd><kwd>противотуберкулезные препараты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>predictive models</kwd><kwd>machine learning</kwd><kwd>boosting</kwd><kwd>molecular docking</kwd><kwd>virtual screening</kwd><kwd>Mycobacterium tuberculosis</kwd><kwd>MmpL3</kwd><kwd>anti-tuberculosis drugs</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке грантов БРФФИ (проект Ф24-КИТГ-016), Международного научно-технического центра (МНТЦ, проект PR150) и Консорциума и Портала программы «Лекарственноустойчивый туберкулез» (https://tbportals.niaid.nih.gov)</funding-statement><funding-statement xml:lang="en">This work was supported by grants from the BRFFR (project Ф24-КИТГ-016), the International Scientific and Technical Center (ISTC, project PR150) and the Consortium and the Drug Resistant Tuberculosis Portal Program (https://tbportals.niaid.nih.gov)</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">The stages of drug discovery and development process / A.
