Противовирусная Активность Компонентов Полифенольного Комплекса Из Морских Трав Семейства Zosteraceae По Отношению К Вирусу Клещевого Энцефалита

Abstract

Одним из возможных подходов к эффективному патогенетически обоснованному лечению клещевого энцефалита (КЭ) является включение природных антиоксидантов в комплексную терапию заболевания. Цель исследования. Изучить in vitro механизмы противовирусного действия полифенольного комплекса (ПФК) и его компонентов (розмариновая кислота, дисульфат лютеолина и лютеолин) из морских трав семейства Zosteraceae по отношению к высокопатогенному для человека штамму вируса КЭ. Материалы и методы. Противовирусную активность соединений оценивали по ингибированию цитопатогенного действия вируса КЭ на культуре клеток СПЭВ с использованием МТТ-анализа. Исследовали различные схемы применения тестируемых соединений: предварительная обработка клеток, вируса и воздействие на раннюю стадию репликации вируса. Результаты. Установлено, что основным механизмом противовирусного действия ПФК и его компонентов является прямая инактивация вирусных частиц и ингибирование вируса КЭ на ранней стадии репликации. Заключение. Показано, что ПФК и его компоненты могут рассматриваться как потенциальные противовирусные соединения в комплексной терапии КЭ. One of the possible approaches to effective pathogenetically based treatment of tick-borne encephalitis (TBE) is the inclusion of natural antioxidants in the complex therapy of the disease. The purpose of the research is to study antiviral action mechanisms of the polyphenol complex (PFC) and its components (rosmarinic acid, luteolin disulfate and luteolin) from seagrass of Zosteraceae family against the highly pathogenic strain of the TBE virus in vitro. Materials and methods. Antiviral activity of the compounds was evaluated by inhibition of cytopathic effect of TBE virus in PK cells using MTT analysis. Different modes of tested compounds application were investigated: pre-treatment of cells, pre-treatment of virus, and effect on the early stage of viral replication. Results. It has been established that the main mechanisms of action PFC and its components are direct inactivation of virus particles and inhibition of the TBE virus at an early stage of replication. Conclusion. It is shown that PFC and its components can be considered as potential antiviral agents in complex therapy of TBE infection.
