На основе микробицидных белков создаются лекарственные антимикробные средства природного происхождения. К настоящему времени показано, что при воздействии ультразвука на лейкоциты при полном разрушении клетки образуются новые соединения — пептидные комплексы, обладающие иммунобиологической активностью. Цель — модернизация параметров влияния ультразвука на донорские лейкоциты для выделения отдельных полипептидных соединений, обладающих биологической активностью. Материал и методы. Новые лейкоцитарные белково-пептидные комплексы получали методом ультразвуковой обработки донорских лейкоцитов. Разделение пептидных комплексов осуществляли на хроматографических колонках Superdex 200 increase. Для изучения их использовали методы ВЭЖХ и инфракрасной спектроскопии. Метод ВЭЖХ реализовывали на хроматографе фирмы Knauer (Германия) с применением спектрофотометрического детектора аналитических длин волн 280 нм и 293 нм. Результаты. Установлено, что различная величина амплитуды ультразвуковых волн и различная продолжительность их воздействия способствуют получению сложных белковых комплексов. При определённых условиях (время обработки донорских лейкоцитов ультразвуком в течение 90 с, с амплитудой 60%, мощностью 50 Вт, частотой 30 кГц) возможно получение комплекса низкомолекулярных пептидов с молекулярной массой менее 6,5 кДа. Методом ИК-Фурье спектрометрии определено, что в состав полученного пептидного комплекса входят такие аминокислоты, как Thr, Ser, Phe, Tyr, His и Trp. Установлено, что данный комплекс обладает антибактериальной активностью. Выводы. Метод воздействия ультразвуком на донорские лейкоциты позволяет получить белковый комплекс с антибактериальной активностью.</p></abstract><trans-abstract xml:lang="en"><p>Relevance. Microbicidal proteins are used to create natural antimicrobial drugs. It has been shown to date that ultrasound exposure of leukocytes results in complete cell destruction and the formation of new compounds — peptide complexes with immunobiological activity. The aim of the study was to update the parameters of ultrasound effect on the donor leukocytes to isolate individual polypeptides with biological activity. Materials and methods. New leukocyte protein-peptide complexes were obtained by ultrasonic treatment of donor leukocytes. Separation of peptide complexes was carried out on Superdex 200 increase chromatographic columns. HPLC and infrared spectroscopy methods were used to study them. The HPLC method was implemented on a Knauer chromatograph (Germany) using a spectrophotometric detector of analytical wavelengths of 280 nm and 293 nm. Results. It has been established that various ultrasound wave amplitudes and durations of their action contribute to the production of complex protein compounds. Under certain conditions (processing donor leukocytes with ultrasound for 90 sec., with an amplitude of 60%, a power of 50 W, and a frequency of 30 kHz), it is possible to obtain a complex of low-molecular peptides with a molecular weight of less than 6.5 kDa. Using Fourier transform infrared spectroscopy, it was determined that the composition of the obtained peptide complex includes amino acids such as Thr, Ser, Phe, Tyr, His, and Trp. It has been established that this complex has antibacterial activity. Conclusion. Ultrasound treatment of donor leukocytes produces a protein complex with antibacterial activity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>антибактериальные пептиды</kwd><kwd>лейкоцитарный пептидный комплекс</kwd><kwd>ультразвуковое воздействие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antibacterial peptides</kwd><kwd>leukocyte peptide complex</kwd><kwd>ultrasound exposure</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">Simonson A.
