The urgency of the development of this method is associated with the need to obtain large quantities of 8-oxo-dG for the study of biological and pharmaceutical activity. Evidence of this need was obtained in the last decades, when the mechanisms of the interface of DNA repair with intracellular signaling through 8-oxo-dG were discovered and its anti-inflammatory and protective effects were revealed. The suggested method is based on the scheme used to prepare 8-oxo-dG-containing oligonucleotides, but has a number of important modifications. The use of N,N-dimethylformamide as a solvent makes it possible to increase the yield of the nucleophilic substitution reaction and avoid expensive and complicated further purification of silver acetate. Control of the reaction kinetics allows achieving the maximum yield and purity of the product. Alkaline hydrolysis, in contrast to ammonolysis, provides complete and rapid removal of acyl groups, and reversed-phase chromatography on silanized silica gel is an effective and inexpensive method of purification. Such a purification scheme minimizes contamination of the product with residual organic solvents, which is important for biological experiments. From the economic point of view, it is advantageous because of the absence of expensive solvents and the possibility of reusing the carrier. The method makes it possible to obtain pure 8-oxo-dG in preparative amounts and exceeds both its prototype and other existing techniques in the final output. Some intermediate compounds and significant methodological features of the reaction are described.</p></abstract><trans-abstract xml:lang="ru"><p>Предложен препаративный метод синтеза 8-оксо-2’-дезоксигуанозина (8-oxo-dG), дающий высокий, до 80%, выход и подходящий для лабораторного применения. Актуальность разработки этого метода связана с возникшей необходимостью получения больших количеств 8-oxo-dG для исследования биологической и фармацевтической активности. Свидетельства о наличии таковой были получены в последние десятилетия, когда были открыты механизмы сопряжения репарации ДНК с внутриклеточной сигнализацией через 8-oxo-dG и обнаружено его противовоспалительное и протекторное действие. Предложенный нами метод основывается на схеме, используемой для получения 8-oxo-dG-содержащих олигонуклеотидов, но имеет ряд важных модификаций. Использование N,N-диметилформамида в качестве растворителя позволяет увеличить выход реакции нуклеофильного замещения и обойтись без применения дорогостоящего и осложняющего дальнейшую очистку ацетата серебра. Контроль кинетики реакции позволяет добиться максимальных выхода и чистоты продукта. Щелочной гидролиз, в отличие от аммонолиза, обеспечивает полное и быстрое удаление ацильных групп, а обращенно-фазовая хроматография на силанизированном силикагеле является эффективным и недорогим методом очистки. Такая схема очистки сводит к минимуму загрязнение продукта остаточными органическими растворителями, что немаловажно для биологических экспериментов. С экономической точки зрения, она выгодна из-за отсутствия дорогостоящих растворителей и возможности многократного использования носителя. Метод позволяет получать чистый 8-oxo-dG в препаративных количествах и превышает по итоговому выходу как свой прототип, так и иные существующие методики. Описаны некоторые промежуточные соединения и значимые методические особенности проведения реакции.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синтез</kwd><kwd>модифицированные нуклеозиды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>8-оксо-2’-дезоксигуанозин</kwd><kwd>8-oxo-dG</kwd><kwd>8-oxo-2'-deoxyguanosine</kwd><kwd>8-oxo-dG</kwd><kwd>synthesis</kwd><kwd>modified nucleosides</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">Lee S.F., Pervaiz S.
