Она основана на использовании галофильной бактериальной культуры Halobacterium salinarum (по прежней классификации Halobacterium halobium), обладающей мевалонатным путём биосинтеза стеролов и значительным сходством их биосинтеза с образованием холестерина в организме человека. ИБС в модели H.salinarum выявляются как соединения, подавляющие рост тест-культуры. Внесение мевалоновой кислоты - одного из ключевых интермедиатов биосинтеза стеролов, снимает ингибирующее действие многих микробных метаболитов и, таким образом, служит доказательством их влияния на ранние этапы биосинтеза стеролов, включая этап работы ГМГ-КоА редуктазы. Тест с H.salinarum разработан в виде микрометода, легко поддается механизации благодаря миниатюризации микробиологических процессов, выращиванию культуры в стерильных 96-луночных планшетах и использованию автоматических микропипеток. Описываемая тест-ситема пригодна для работы с грубоочищенными экстрактами культуральной жидкости микроорганизмов-продуцентов и может быть с успехом применена на начальных этапах поиска. Показана возможность применения теста H.salinarum для поиска противоопухолевых антибиотиков.</p></abstract><trans-abstract xml:lang="en"><p>A highly effective and simple microbial test system for screening inhibitors of sterol biosynthesis (ISB) is described. The system is based on cultivation of the bacterial strain Halobacterium salinarum (former Halobacterium halobium), that possesses mevalonate pathway of sterol biosynthesis and is much similar in the biosynthesis to cholesterol formation in humans. In the H.salinarum test system the ISB were found as compounds that inhibited the test culture growth. Mevalonate which is one of the crucial intermediates of sterol biosynthesis dismissed the inhibitory effect of many microbial metabolites thus being evident of their action at the early stages of the sterol biosynthesis, including the HMG-CoA reductase stage. The H.salinarum test system was developed as a micromethod and could be easily mechanized by miniaturization of the microbiological procedures, cultivation in sterile 96-well plates and using automatic micropipettes and dispensers. The H.salinarum test system was effective in testing crude extracts of the culture broths and advantageous at early stage of screening. The use of the H.salinarum test system was shown possible for screening antitumor antibiotics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ингибиторы биосинтеза стеролов</kwd><kwd>противоопухолевые антибиотики</kwd><kwd>микробные модели поиска</kwd><kwd>мевалоновая кислота</kwd><kwd>ГМГ-КоА редуктаза</kwd><kwd>ловастатин</kwd><kwd>миниатюризация</kwd><kwd>механизация микробиологических процессов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>archaea</kwd><kwd>inhibitors of sterol biosynthesis</kwd><kwd>antitumor antibiotics</kwd><kwd>archaea</kwd><kwd>microbial models for screening</kwd><kwd>mevalonate</kwd><kwd>HMG-CoA reductase</kwd><kwd>lovastatin</kwd><kwd>miniaturization</kwd><kwd>mechanization of microbial processes</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">Тренин А.С., Катруха Г.С.
