Одним из таких является N-(5-хлорпиридин-2-ил)-2-({4 [этанимидоил(метил)амино]бензоил}амино)-5-метилбензамида гидрохлорид (далее – DD217) – инновационный препарат, относящийся к классу антикоагулянтов, ингибиторов фактора Xa.</p></sec><sec><title>Цель</title><p>Цель. Целью настоящего исследования явилась разработка и валидация методики определения DD217 в плазме крови крыс методом высокоэффективной жидкостной хроматографии с тандемным масс-спектрометрическим детектированием (ВЭЖХ-МС/МС) и применение разработанной методики для проведения фармакокинетических исследований.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследовании были использованы аутбредные крысы Wistar. Крысам вводили раствор субстанции DD217 однократно, внутрижелудочно в дозах 5, 15, 30 мг/кг. Для определения DD217 в плазме крови крыс применяли валидированную методику определения DD217 методом высокоэффективной жидкостной хроматографии с тандемным масс-спектрометрическим детектированием (ВЭЖХ-МС/МС). В качестве внутреннего стандарта был выбран небиволол. Хроматографическое разделение проводилось с использованием колонки Phenomenex Luna С8 (3 мкм, 50 × 4,6 мм). В качестве подвижной фазы использовали 0,1%-й раствор муравьиной кислоты в деионизованной воде и 0,1%-й раствор муравьиной кислоты в ацетонитриле. Общее время анализа каждого образца составляло 2,0 мин. DD217 и небиволол детектировали в режиме положительной ионизации электроспреем по ионным переходам m/z 436,1 → 119,9 и 406,0 → 151,0 соответственно. Фармакокинетические параметры и описательную статистику рассчитывали модельно-независимым методом при помощи программного обеспечения IBM SPSS Statistics v27 и Julia v1.6.0 (Mixed Models v3.8.0, ClinicalTrialUtilities v0.5.1).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Разработанная методика была валидирована по следующим показателям: нижний предел количественного определения, селективность, правильность и прецизионность, допустимость разведения, линейность, эффект матрицы, степень извлечения, эффект переноса и стабильность. Нижний предел количественного определения DD217 в плазме крови крыс составил 2,0 нг/мл. Разработанная методика была успешно применена для определения фармакокинетических параметров субстанции DD217 в плазме крови крыс после внутрижелудочного введения в дозах 5, 15, 30 мг/кг.</p></sec><sec><title>Заключение</title><p>Заключение. Методика для количественного определения DD217 в плазме крови впервые разработана, валидирована и применена для оценки фармакокинетических параметров субстанции DD217 в плазме крови крыс.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Nowadays, discovery and development of innovative drugs represent a relevant goal for the pharmaceutical market. One of such drugs is N-(5-chloropyridine-2-yl)-2-({4-[ethanimidoyl(methyl)benzoyl}amino)-5-methylbenzamide hydrochloride (hereinafter DD217), an innovative drug that belongs to the class of anticoagulants, namely factor Xa inhibitors.</p></sec><sec><title>Aim</title><p>Aim. The aim of this study was to develop and validate a method for DD217 determination in rat plasma by means of high-performance liquid chromatography–tandem mass spectrometry (HPLC-MS/MS) to carry out pharmacokinetic studies.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Outbred Wistar rats were used in the study. Rats received a single dose of DD217 substance solution intragastrically at a dose of 5, 15, 30 mg/kg. The validated HPLC-MS/MS method was employed for DD217 determination in rat plasma. Nebivolol was chosen as the internal standard of the method. Chromatographic separation involved the use of Phenomenex Luna С8 column (3 µm, 50 × 4.6 mm) and gradient elution with water-acetonitrile solution containing 0.1 % formic acid. The total run time of each sample was equal to 2.0 min. DD217 and nebivolol were detected in positive electrospray ionization mode, the ion transitions monitored were m/z 436,1 → 119,9 and 406,0 → 151,0, respectively. Pharmacokinetic parameters and descriptive statistics were calculated through model-independent method in IBM SPSS Statistics v27 and Julia v1.6.0 (MixedModels v3.8.0, ClinicalTrialUtilities v0.5.1) software.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Method was validated by linearity, lower limit of quantification, selectivity, accuracy and precision, dilution integrity, matrix effect, recovery, carry-over, and stability. The lower limit of quantification of DD217 in rat plasma was 2.0 ng/mL. The method was successfully applied for establishing the pharmacokinetic parameters of DD217 substance in rat plasma after intragastric administration at a dose of 5, 15, 30 mg/kg.</p></sec><sec><title>Conclusion</title><p>Conclusion. HPLC-MS/MS method for DD217 determination in plasma was developed, validated and applied in order to evaluate pharmacokinetic parameters of DD217 substance in rat plasma.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>DD217</kwd><kwd>крысы</kwd><kwd>плазма</kwd><kwd>ВЭЖХ-МС/МС</kwd><kwd>валидация</kwd><kwd>фармакокинетика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>DD217</kwd><kwd>rat</kwd><kwd>plasma</kwd><kwd>HPLC-MS/MS</kwd><kwd>validation</kwd><kwd>pharmacokinetics</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">Glushchenko V.
