Representatives of this genus are easily renewable, resistant to various environmental factors, therefore, they are the object of fundamental and applied research in many aspects.</p> <p><italic>Skeletonema sp. </italic>exhibits various types of pharmacological activity. Thus, the antimicrobial effect of <italic>Skeletonema sp.</italic> in relation to <italic>Streptococcus pyogenes,</italic> <italic>Bacillus subtilis, Staphylococcus aureus, Fusarium moniliforme, Cutibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, Mycobacterium tuberculosis, Mycobacterium bovis</italic>. <italic>Skeletonema sp.</italic> can be used in dermatovenereology and pulmonology due to antimicrobial effect of pheophorbide in microalgae chemical composition. Pronounced antioxidant and anti-inflammatory activity of <italic>Skeletonema sp.</italic> may stem from exopolysaccharides, phenolic compounds, ascorbic acid and pigments. A number of studies show the possibility of using biologically active compounds of the <italic>Skeletonema</italic> river representatives (monoacylglycerols, polyunsaturated aldehydes, oxoacids, fucoxanthin) as promising anti-cancer agents and have promising potential for the treatment of colon cancer, histiocytic lymphoma, prostate cancer and melanoma. Osteoprotective action is based on the ability to modulate the immune response and inhibit osteoclastogenesis, expanding the range of treatments for osteoporosis and other diseases of the musculoskeletal system caused by inflammation. The anticonvulsant activity of <italic>Skeletonema sp.</italic> Extract was also revealed, apparently due to the presence of inosine, which can find its application in the treatment of neurological disorders.</p> <p>This review includes an analysis of 32 domestic and foreign literature sources posted in the open database eLIBRARY and PubMed and devoted to the study of chemical composition and pharmacological properties of Skeletonema sp. This work will help assess the relevance and prospects of further research of diatoms of the genus <italic>Skeletonema</italic> as a source of valuable biologically active substances and their therapeutic potential.</p></abstract><trans-abstract xml:lang="ru"><p>Диатомовые водоросли рода <italic>Skeletonema</italic> являются новым источником высокоценных метаболитов, потенциально пригодных для использования в различных отраслях промышленности, в том числе в фармацевтическом секторе и медицине. Представители данного рода являются легко возобновляемыми, устойчивыми к различным факторам окружающей среды, поэтому являются объектом фундаментального и прикладного изучения во многих аспектах.</p> <p><italic>Skeletonema sp.</italic> проявляет различные виды фармакологической активности. Так, установлен антимикробный эффект экстрактов <italic>Skeletonema sp.</italic> в отношении <italic>Streptococcus pyogenes</italic>, <italic>Bacillus subtilis</italic>, <italic>Staphylococcus aureus</italic>, <italic>Fusarium moniliforme</italic>, <italic>Cutibacterium acnes, Staphylococcus aureus, Staphylococcus epidermidis, Mycobacterium tuberculosis, Mycobacterium bovis</italic>. Препараты на основе <italic>Skeletonema sp.</italic> могут быть использованы в дерматовенерологии и пульмонологии за счет противомикробного эффекта феофорбида в химическом составе микроводоросли. Выраженная антиоксидантная и противовоспалительная активность препаратов <italic>Skeletonema sp.</italic> может быть обусловлена наличием экзополисахаридов, фенольных соединений, аскорбиновой кислоты и пигментов. Ряд исследований показывает возможность использования биологически активных соединений представителей <italic>р. Skeletonema </italic>(моноацилглицеролов, полиненасыщенных альдегидов, оксокислот, фукоксантина) в качестве перспективных противораковых агентов и обладают многообещающим потенциалом для лечения рака толстой кишки, гистиоцитарной лимфомы, рака предстательной железы и меланомы. Остеопротекторное действие основано на способности модулировать иммунный ответ и ингибировать остеокластогенез, расширяя спектр методов лечения остеопороза и других заболеваний опорно-двигательной системы, вызванных воспалением. Также выявлена противосудорожная активность экстракта <italic>Skeletonema sp.</italic>, по-видимому, обусловленная наличием инозина, что может найти свое применение при лечении неврологических расстройств.</p> <p>Настоящий обзор включает анализ 32 отечественных и зарубежных литературных источников, размещенных в открытой базе данных eLIBRARY и PubMed и посвященных изучению химического состава и фармакологических свойств <italic>Skeletonema sp. </italic>Данная работа поможет оценить актуальность и перспективность дальнейшего исследования диатомовых водорослей рода <italic>Skeletonema</italic> в качестве источника ценных биологически активных веществ и их терапевтический потенциал.</p></trans-abstract><kwd-group xml:lang="en"><kwd>diatoms</kwd><kwd>Skeletonema</kwd><kwd>pharmacological properties</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>диатомовые водоросли</kwd><kwd>Skeletonema</kwd><kwd>фармакологические свойства</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lauritano C, Martín J, de la Cruz M, et al.
