   <abstract xml:lang="ru">
    <p>Разработка наноконтейнеров для адресной доставки лекарственных препаратов в соответствующие органы является одним из активно развивающихся направлений биомедицинской химии. В представляемой работе был проведен синтез биодеградируемого блок-сополимера на основе лактида молочной кислоты (ПМК) с метиловым эфиром поли(этиленгликоля)-5000. Полимеризацию проводили по ионно-координационному механизму в расплаве. Для характеризации образов использовали методы 1Н-ЯМР и гель проникающей хроматографии. Полимерные частицы с размером от 40 до 200 нм были получены методом наноoсаждения. В процессе формирования в полимерные биодеградируемые контейнеры инкапсулировали цитостатический препарат диоксадэт, который применяется для лечения рака яичников. Эффективность инкапсулирования для разработанных систем варьировалась от 46 до 83 %, максимальное количество инкапсулированного препарата составило 230 мкг/мг полимерных частиц.</p>

    <p>The preparation of nanocontainers for targeted drug delivery is a rapidly developing field of biomedical chemistry. The synthesis of biodegradable block copolymer of polyethylene glycol (PEG-5000) with polylactic acid (PLA) was performed via stannous octoate initiated ring-opening polymerization in bulk. Molecular weights and molecular weight distribution of obtained polymer were studied by Size exclusion chromatography (SEC). For the characterization of obtained samples 1H-NMR was used. Polymer particles with the sizes from 40 to 200 nm were prepared by nanoprecipitation method. Dioxadet was encapsulated in biodegradable polymer containers this cytotoxic drug used for the treatment of ovarian cancer. The encapsulation efficiency for the developed systems ranged from 46 to 83%, the loading content was equal to 230 μg mg-1 of particles.</p>
