The compound STOCK7S-36520, selectively cytotoxic in the coculture of breast tumor cells MCF7’ and non-tumor MCF10A, contains structural elements characteristic of kinase inhibitors. Analyzing the compound STOCK7S-36520 and its derivative STOCK7S-47016, it turned out that they are new multikinase inhibitors. The highest inhibition of 84% was shown by compound STOCK7S-47016 against GCK kinase. Of interest is the significant selectivity of action against some of the cell lines studied: the selectivity index of STOCK7S-36520 against the prostate tumor cell line PC3 is 29 times compared to the model line of non-tumor fibroblasts VA13.</p></abstract><trans-abstract xml:lang="ru"><p>Для поиска избирательно действующих на опухолевые клетки веществ в работе использован фенотипический скрининг в сокультуре опухолевых клеток с неопухолевыми. Найденное избирательно цитотоксичное в сокультуре опухолевых клеток молочной железы MCF7' и неопухолевых MCF10A соединение STOCK7S-36520 содержит структурные элементы, характерные для ингибиторов киназ. При анализе соединения STOCK7S-36520 и его производного STOCK7S-47016 оказалось, что они являются новыми мультикиназными ингибиторами. Наибольшее ингибирование в 84% показало соединение STOCK7S-47016 против киназы GCK. Интерес представляет значимая избирательность действия против некоторых из исследованных клеточных линий: индекс селективности STOCK7S-36520 против линии опухолевых клеток простаты PC3 составляет 29 раз по сравнению с модельной линией неопухолевых фибробластов VA13.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Co-culture</kwd><kwd>phenotypic screening</kwd><kwd>anticancer</kwd><kwd>cytotoxicity</kwd><kwd>breast cancer model</kwd><kwd>lung cancer model</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>цитотоксичность</kwd><kwd>противоопухолевые препараты</kwd><kwd>ингибиторы киназ</kwd><kwd>FCCT-тест</kwd><kwd>селективность</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>22-14-00099</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Jaffee, E.M., C.V.
