Исследование фармакокинетических свойств соединения RU-1205, с ранее выявленным каппа-агонистическим и анальгетическим действием, при однократном пероральном введении, а также сопоставление взаимосвязи между его фармакокинетическими и обезболивающими свойствами.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Фармакокинетические параметры RU-1205 после перорального введения в дозе 50 мг/кг исследовали с помощью метода высокоэффективной жидкостной хроматографии с определением концентрации соединения по предварительно построенному калибровочному графику. Рассчитывали показатели площади под фармакокинетической кривой, клиренса, периода полувыведения, время пребывания в организме молекулы препарата, общего (кажущегося) объём распределения, а также показатель абсолютной биодоступности. Изучали тканевое распределение и экскрецию RU-1205. Осуществляли прогноз возможных метаболитов соединения RU-1205 с помощью программы «PALLAS 3.00». Исследование анальгетической активности проводили на модели центральной соматогенной боли при электрическом раздражении с оценкой динамики амплитуды напряжения соответствующей реакции «отдергивания хвоста».</p></sec><sec><title>Результаты</title><p>Результаты. Изучаемое соединение быстро адсорбируется из желудочно-кишечного тракта с достижением максимальной концентрации к концу первого часа исследования и определяется в плазме в течение 12 часов. Период полувыведения составляет 17,7 ч. Абсолютная биодоступность при пероральном пути - 37,3%. Установлено, что соединение выводится за 3-4 дня. Основной путь выведения внепочечный. Биотрансформация вещества вероятно протекает в основном с образованием окисленных форм исходной молекулы по реакциям первой фазы метаболической трансформации. Анальгетическое действие продолжительное: начинается через 15 минут и сохраняется в течении 12 часов с выходом на плато к 8 часу.</p></sec><sec><title>Заключение</title><p>Заключение. Исследуемое вещество подвергается длительному процессу элиминации при пероральном введении, имеет наибольшую тропность к органам элиминации и подвергается активным процессам биотрансформации в организме животных, в результате которых, возможно, образуются активные продукты метаболизма с анальгетической активностью.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study is the investigation of the pharmacokinetic properties of the RU-1205 compound, with previously identified kappa-agonistic and analgesic effects, at a single oral administration, as well as comparison of the relationship between its pharmacokinetic and analgesic properties.</p><sec><title>Materials and methods</title><p>Materials and methods. Pharmacokinetic parameters of RU-1205 after the oral administration at the dose of 50 mg / kg were investigated using the method of High Performance Liquid Chromatography  with determination of the concentration of the compound according to the previously constructed calibration schedule. The indices of the area under the pharmacokinetic curve, clearance, half-life, residence time of the drug molecule in the body, a total (apparent) volume of distribution, as well as the indicator of absolute bioavailability, were calculated. The tissue distribution and excretion of RU-1205 were studied.</p><p>Potential metabolites of RU-1205 were predicted using the PALLAS 3.00 program. The study of the analgesic activity was carried out on a model of central somatogenic pain with electricalstimulation, with the dynamics assessment of the voltage amplitude of the corresponding reaction of the "tail-flick" reflex.</p></sec><sec><title>Results</title><p>Results. The compound under study is rapidly adsorbed from the gastrointestinal tract, reaching a maximum concentration by the end of the first hour of the study, and is determined in plasma within 12 hours. Its half-life is 17.7 hours. The absolute oral bioavailability is 37.3%. It was found out that the compound is withdrawn within 3-4 days. The main route of excretion is extrarenal. Biotransformation of a substance probably proceeds mainly with the formation of oxidized forms of the initial molecule by reactions of the first phase of metabolic transformation. The analgesic effect is long-lasting: it starts after 15 minutes and lasts for 12 hours with flattening of the curve by the 8th hour.</p></sec><sec><title>Conclusion</title><p>Conclusion. When administered orally, the test substance undergoes a long process of elimination, has the greatest tropism for the elimination organs and undergoes active biotransformation processes in the body of animals. As a result of it, active metabolic products with an analgesic activity are, possibly, formed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>каппа-агонисты</kwd><kwd>опиоидные анальгетики</kwd><kwd>бензимидазолы</kwd><kwd>фармакокинетика</kwd><kwd>пероральный путь</kwd><kwd>биодоступность</kwd><kwd>экскреция</kwd><kwd>тканевое распределение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>kappa agonists</kwd><kwd>opioid analgesics</kwd><kwd>benzimidazoles</kwd><kwd>pharmacokinetics</kwd><kwd>peroral route</kwd><kwd>bioavailability</kwd><kwd>excretion</kwd><kwd>tissue distribution</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Синтез соединения RU-1205 выполнен при финансовой поддержке Министерства науки и высшего образования  РФ в рамках Госзадания , грант FENW-2020-0031 (0852-2020-0031)</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The synthesis of the RU-1205 compound was carried out with the financial support of the Ministry of Science and Higher Education of the Russian Federation within the framework of the State Assignment, grant FENW-2020-0031 (0852-2020-0031)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Harbaugh C.M., Suwanabol P.A.
