Аннотация
Современная фармацевтическая наука претерпевает значительные изменения благодаря активному внедрению компьютерных технологий в процесс разработки лекарственных средств. Перед традиционными этапами синтеза и экспериментальной проверки исследователи все чаще применяют in silico подходы, позволяющие с высокой точностью моделировать структуру и фармакологические эффекты химических соединений. Такой подход обеспечивает значительную экономию временных и финансовых ресурсов, оптимизируя последующие экспериментальные исследования. Параллельно с этим наблюдается активное развитие эпигеном-направленной терапии — нового подхода, позволяющего модулировать экспрессию генов, вовлеченных в патологические процессы, без прямого воздействия на первичную структуру ДНК. В данной работе на примере хелидоновой кислоты представлен комплексный алгоритм оценки влияния малых молекул на экспрессию генов и метаболических путей. Методика основана на использовании веб-сервиса DIGEP-Pred 2.0 с последующим многоуровневым биоинформатическим анализом, включающим: (1) анализ избыточной репрезентативности генов; (2) оценку вовлеченности метаболических путей; (3) их функциональную кластеризацию. Предлагаемый подход способствует решению задач как для фундаментальных, так и для прикладных исследований механизмов действия лекарственных веществ.

Abstract
Modern pharmaceutical science is undergoing significant changes due to the active integration of computer technologies into the drug development process. Prior to the conventional stages of synthesis and experimental testing, researchers are increasingly turning to in silico methods, which enable the simulation of the structure and pharmacological effects of chemical compounds with a high degree of predictive accuracy. This approach significantly saves time and financial resources, optimizing subsequent experimental studies. In parallel, there is an active development of epigenome-targeted therapy, a new approach that allows for the modulation of gene expression involved in pathological processes without directly altering the primary DNA structure. Using chelidonic acid as a case study, we present a pipeline for computer-based assessment of small molecule effects on gene expression and metabolic pathways. The algorithm is based on the use of the DIGEP-Pred 2.0 web service, followed by multilevel bioinformatics analysis, including: (1) gene over-representation analysis; (2) assessing the involvement of metabolic pathways; (3) functional clustering of pathways. The proposed approach can help solve problems in both fundamental and applied research on the molecular mechanisms of drug action.
