В работе подобраны технологические параметры, позволяющие оптимизировать метод получения наночастиц с заданными характеристиками, в результате был получен образец сферических частиц, обладающая средним диаметром частиц 222,6±2,8 нм; ξ-потенциалом –26,3±4,61 мВ; индексом полидисперсности 0,144; общее содержание DPBPI в частицах PLGA-DPBPI составило13,6%. В соответствии с разработанной методикой была осуществлена наработка партии наночастиц PLGA-DPBPI для дальнейших биологических исследований. В экспериментах in vitro на клетках немелкоклеточной карциномы легкого человека А549 для DPBPI, доставленного в клетки с помощью наночастиц PLGA-DPBPI, и эмульсии на основе кремофора EL (CrEL-DPBPI) было показано сходное внутриклеточное распределение (концентрирование в везикулярных клеточных структурах и диффузное распределение в цитоплазме), а также была показана высокая фотоиндуцированная активность и отсутствие темновой цитотоксичности в случае использования частиц PLGA-DPBPI. Изучение специфической активности наночастиц PLGA-DPBPI in vivo на модели саркомы мягких тканей мыши S37 показало селективное накопление DPBPI в опухолевой ткани и практически полное выведение DPBPI из организма в течение 48 ч, а также выраженную противоопухолевую эффективность при ФДТ.</p></abstract><trans-abstract xml:lang="en"><p>The article describes the process of developing a technology for producing nanoparticles based on a copolymer of lactic and glycolic acids (PLGA) containing dipropoxybacteriopurpurinimide (DPBPI) for photodynamic therapy of malignant tumors of various origins. Technological parameters for optimizing the method in order to obtain nanoparticles with specified characteristics are presented in this paper. As a result, the nanoparticles sample with an average particle diameter of 222.6±2.8 nm; ξ-potential 26.3±4.61 mV; polydispersity index 0.144; the total content of DPBPI in PLGA-DPBPI nanoparticles 13.6% were obtained. In accordance with the developed technique, the batch of PLGA-DPBPI nanoparticles was developed for further biological studies. In vitro experiments on A549 human non-small cell lung carcinoma for DPBPI, delivered as a part of PLGA-DPBPI nanoparticles, and an EL cremophor-based emulsion (CrEL-DPBPI) showed a similar intracellular distribution (concentrated in vesicular cell structures and diffusely distributed in cytoplasm), as well as high photo induced activity and the absence of dark cytotoxicity in case of PLGA-DPBPI nanoparticles. The study of the PLGA-DPBPI nanoparticles specific activity in vivo on the S37 mouse soft tissue sarcoma model showed the selective accumulation of DPBPI in tumor tissue and the almost complete elimination of DPBPI from the body within 48 hours, as well as significant antitumor efficacy in PDT.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотодинамическая терапия</kwd><kwd>наночастицы</kwd><kwd>PLGA</kwd><kwd>фотосенсибилизатор</kwd><kwd>фотоиндуцированная активность</kwd><kwd>фотоиндуцированная противоопухолевая эффективность</kwd><kwd>дипропоксибактериопурпуринимид</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photodynamic therapy</kwd><kwd>nanoparticles</kwd><kwd>PLGA</kwd><kwd>photosensitizer</kwd><kwd>photoinduced activity</kwd><kwd>photoinduced antitumor efficacy</kwd><kwd>dipropoxybacteriopurpurinimide</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">Rejman J., Oberle V., Zuhorn I.S., Hoekstra D.
