Кроме EA-3167 в жидкостях обнаружили добавки метадона, α-пирролидиновалерофенона и тетрагидроканнабинола.Цель работы – установление аналитических характеристик EA-3167, а также его метаболитов в моче крыс.Методы исследования. Структурная идентификация обнаруженного вещества методом ядерного магнитного резонанса, газовая и жидкостная хроматомасс-спектрометрия доставленных объектов и мочи крыс, полученной экспонированием лабораторных животных обнаруженным веществом. Результаты исследования. Концентрации EA-3167 в жидкостях составляли 910 и 3,9 мкг/мл соответственно. Установлено, что EA-3167 подвержен интенсивному метаболизму в организме крыс. В моче лабораторных животных предположительно идентифицированы более 30 метаболитов, представляющих собой продукты моно- и дигидроксилирования алифатических остатков молекулы, образования кетона, а также гидролиза. Вывод. Наиболее удобными мочевыми маркерами для подтверждения отравления EA-3167 методами газовой и жидкостной хроматомасс-спектрометрии являются исходное вещество, продукты его моногидроксилирования и образования карбонильной группы на циклопентильном остатке.</p></abstract><trans-abstract xml:lang="en"><p>Earlier, we found that two alcohol-containing samples delivered from the zone of special military operation contain a rare psychoactive substance EA-3167, which is a structural analogue of the well-known incapacitant BZ, included in the Schedule 1 of the Chemical Weapons Convention. In addition to EA-3167, additives of methadone, α-pyrrolidinovalerophenone and tetrahydrocannabinol were found in liquids.The aim of the work is to establish the analytical characteristics of EA-3167, as well as its metabolites in rat urine. Research methods. Structural identification of the detected substance by nuclear magnetic resonance, gas and liquid chromatomass spectrometry of delivered objects and rat urine obtained by exposing laboratory animals to the detected substance.The results of the study. Concentrations of EA-3167 in liquids were found to be 910 and 3.9 μg/mL, respectively. It has been established that EA-3167 is subject to intensive metabolism in rats. More than 30 metabolites, representing products of mono- and dihydroxylation of aliphatic moieties of the molecule, ketone formation, and hydrolysis, have been tentatively identified in the urine of laboratory animals. Conclusion. The most convenient markers for confirming poisoning of EA-3167 by gas and liquid chromatography-mass spectrometry were the parent substance, the products of its monohydroxylation and the formation of carbonyl group on the cyclopentyl moiety.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>EA-3167</kwd><kwd>BZ</kwd><kwd>биологические объекты</kwd><kwd>газовая хроматомасс-спектрометрия</kwd><kwd>жидкостная хроматомасс-спектрометрия</kwd><kwd>инкапаситанты</kwd><kwd>метаболиты</kwd><kwd>пищевые объекты</kwd><kwd>психоактивные вещества</kwd><kwd>специальная военная операция</kwd><kwd>точные массы</kwd><kwd>ядерный магнитный резонанс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>accurate masses</kwd><kwd>biological objects</kwd><kwd>BZ</kwd><kwd>EA-3167</kwd><kwd>food objects</kwd><kwd>gas chromatography-mass spectrometry</kwd><kwd>incapacitants</kwd><kwd>liquid chromatography-mass spectrometry</kwd><kwd>metabolites</kwd><kwd>nuclear magnetic resonance</kwd><kwd>psychoactive substances</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">Ellison DH.
