Новое фармакологически активное вещество 3-(2-бутил-5-хлоро-1Н-имидазол-4-ил)-N-[4-метокси-3-(трифторметил)фенил]-4,5-дигидро-1,2-оксазол-5-карбоксамид (R004) является новым ингибитором PAR-2-рецепторов для терапии ревматоидного артрита. Данное соединение находится на этапе доклинического исследования. Изучение распределения R004 и его метаболитов по органам и тканям ранее не проводилось.</p></sec><sec><title>Цель</title><p>Цель. Изучение распределения R004 и его метаболитов по органам и тканям крыс после однократного перорального введения субстанции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование проводилось на 50 крысах-самцах линии Wistar. Субстанция R004 вводилась перорально в терапевтической дозировке 10 мг/кг. Отбор образцов печени, почек, сердца, легких, селезенки, мозга, кожи и мышц проводился через 1, 2, 3, 4, 6, 8, 10, 12, 16, 24 ч после введения лекарственного средства. Органы немедленно гомогенизировались с использованием ацетонитрила и замораживались. Дальнейшую пробоподготовку осуществляли путем добавления к гомогенатам ацетонитрильного раствора внутренних стандартов. Количественное определение R004 и его метаболитов 3-(2-бутил-5-хлоро-1Н-имидазол-4-ил)-4,5-дигидро-1,2-оксазол-5-карбоновой кислоты (М1) и 4-метокси-3-(трифторметил)анилина (M2) проводилось методом ВЭЖХ-МС/МС.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Биоаналитическая методика количественного определения R004, M1 и M2 в органах и тканях была успешно валидирована в аналитических диапазонах 2–2000 нг/г для R004 и 1–1000 нг/г для М1 и М2. R004 распределяется по всем изучаемым биологическим объектам. Тканевая биодоступность R004 уменьшается в следующей последовательности: печень &gt; кожа &gt; почки &gt; легкие &gt; мышцы &gt; сердце &gt; селезенка &gt; мозг. М1 и М2 в больших количествах обнаружены в печени и почках. В сердце, легкие и селезенку метаболиты проникали в значительно меньших концентрациях. В тканях кожи идентифицирован только М2. В мозге и мышцах М1 и М2 не обнаружены.</p></sec><sec><title>Заключение</title><p>Заключение. Валидированная биоаналитическая методика была успешно использована при изучении распределения субстанции R004. Действующее вещество хорошо распределяется по всем изучаемым органам и имеет высокую тканевую биодоступность. Наибольшие концентрации метаболитов зафиксированы в печени и почках.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The new pharmacologically active substance 3-(2-butyl-5-chloro-1H-imidazole-4-yl)-N-[4-methoxy-3-(trifluoromethyl)phenyl]-4,5-dihydro-1,2-oxazole-5-carboxamide (R004) is a new PAR-2 receptor inhibitor for treatment of rheumatoid arthritis. This compound is at the stage of preclinical trail. The distribution study of R004 and its metabolites by organs and tissues has not been performed before.</p></sec><sec><title>Aim</title><p>Aim. The investigation of distribution of R004 and its metabolites in rat organs after a single oral administration of the active substance.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was carried out on 50 male Wistar rats. Substance of R004 was administered orally at a therapeutic dosage of 10 mg/kg. Sampling of liver, kidneys, heart, lungs, spleen, brain, skin and muscles was performed 1, 2, 3, 4, 6, 8, 10, 12, 16, 24 h after administration of the drug. Organs were immediately homogenized using acetonitrile and frozen. Further sample preparation was carried out by addition an acetonitrile solution of internal standards to the homogenates. Quantification of R004 and its metabolites 3-(2-butyl-5-chloro-1H-imidazole-4-yl)-4,5-dihydro-1,2-oxazole-5-carboxylic acid (M1) and 4-methoxy-3-(trifluoromethyl)aniline (M2) was performed by HPLC-MS/MS.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The developed method for quantification of R004, M1 and M2 in organs has been successfully validated in the analytical ranges of 2–2000 ng/g for R004 and 1–1000 ng/g for M1 and M2. R004 is distributed by all studied biological objects. The tissue bioavailability of R004 decreases in the following sequence: liver &gt; skin &gt; kidneys &gt; lungs &gt; muscles &gt; heart &gt; spleen &gt; brain. M1 and M2 was detected in large quantities in liver and kidneys. Metabolites penetrated into the heart, lungs and spleen in much lower concentrations. In skin tissues only M2 was identified. M1 and M2 were not found in brain and muscles.</p></sec><sec><title>Conclusions</title><p>Conclusions. The validated bioanalytical method has been successfully used for distribution study of R004 substance. The drug is well distributed throughout the studied organs and has a high tissue bioavailability. The highest concentrations of metabolites were observed in liver and kidneys.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ингибитор PAR-2-рецепторов</kwd><kwd>ВЭЖХ-МС/МС</kwd><kwd>валидация</kwd><kwd>фармакокинетика</kwd><kwd>распределение</kwd><kwd>гомогенизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PAR-2 receptor inhibitor</kwd><kwd>HPLC-MS/MS</kwd><kwd>validation</kwd><kwd>pharmacokinetics</kwd><kwd>distribution</kwd><kwd>homogenization</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Грант Российского научного фонда № 22-13-20085.</funding-statement><funding-statement xml:lang="en">Grant of Russian Scientific Fund № 22-13-20085.</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">Korsakov M.
