On the basis of the new and improved methods of syntheseis two- and threelink biologically active assemlies of cycles with terminal coumarin links containing thriazole, indolizine, azoindolizine, 1, 3, 4-thiadiazine, furane, quinoxaline and oxazole rings are synthesized. The biological activity of 3-thiazolylcoumarins is investigated. It is stated that all of the compounds under investigation are low toxic and some of them manifest the pronounetd diuretic, antiinflammatory and membrane-stabilizing activities.</p></abstract><trans-abstract xml:lang="ru"><p>Кумарины (2H-1-бензопиран-2-оны) привлекают повышенное внимание исследователей, занятых поиском новых биологически активных веществ, обладающих широким спектром физиологической и фармакологической активности. Среди соединений этого класса найдены перспективные субстанции, некоторые из них внедрены в медицинскую практику [3, 8]. Фармакологический потенциал производных кумарина далеко не исчерпан. В настоящей работе представлен обзор результатов исследований, проведенных в области конструирования и синтеза ансамблей гетероциклов, содержащих кумариновые звенья с целью поиска новых высокоэффективных биологически активных веществ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Kazan Medical archive</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Казанский медицинский архив</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Журавель И.
