Изучение противоопухолевого эффекта трополона 2-(1,1‑диметил‑1h-бензо[e]индолин‑2‑ил)-5,6,7‑трихлор‑1,3‑трополона (JO‑122(2)) в монотерапии и в комбинации с фторурацилом на подкожных CDX-моделях рака желудка.Материалы и методы. Работа выполнена на самках мышей линии BALB/c Nude (n = 32) в возрасте 6–8 нед. CDX-модели созданы методом подкожного введения опухолевой культуры аденокарциномы желудка AGS человека в количестве 5 × 106 клеток на мышь. После того как опухолевые узлы достигали объема 70–100 мм³, животные были разделены на 4 группы (по 8 особей в каждой) так, чтобы разброс средних значений объема опухолевых узлов между ними был минимальным. Замеры опухолевых узлов выполняли два раза в неделю. Эффективность терапии оценивали с помощью торможения роста опухоли (ТРО, %). Статистическую обработку данных проводили при помощи пакета программ Microsoft Excel 2013 и STATISTICA 12. Для оценки различий между опытными и контрольной группами использовали U-критерий Манна – Уитни. Различия считали статистически значимыми при р &lt; 0,05.Результаты. В результате эксперимента получены подкожные CDX-модели аденокарциномы желудка. На них установлено, что применение JO‑122(2) в монотерапии статистически значимо не влияло на рост опухолевых узлов. Наибольшую противоопухолевую активность наблюдали в группе с комбинированным лечением (JO‑122(2) + 5‑фторурацил). Среднее значение объемов опухолевых узлов на конец эксперимента (29‑е сутки после начала лечения) в этой группе составило 513,98 ± 56,50 мм³, тогда как в контрольной группе – 915,08 ± 49,93 мм³. При сравнении показателей роста опухолей между группами с монотерапией 5‑фторурацилом и комбинированным лечением установлены статистически значимые отличия (с 22‑го дня эксперимента). Также в группе с комбинацией препаратов отмечено наибольшее значение ТРО – 43,83 %.Заключение. Полученные результаты свидетельствуют о более эффективном противоопухолевом действии на моделях аденокарциномы желудка при использовании трополона в комбинации с цитостатиком. Это свидетельствует о перспективности данного соединения и возможности для продолжения его исследования.</p></abstract><trans-abstract xml:lang="en"><p>Purpose of the study. The present study investigates the antitumour effect of tropolone 2-(1,1‑dimethyl‑1H-benzo[e]indolin‑2‑yl)-5,6,7‑trichloro‑1,3‑tropolone (JO‑122(2)) in monotherapy and in combination with fluorouracil in subcutaneous CDX models of gastric cancer.Materials and methods. The experimental work was conducted on female BALB/c Nude mice (n = 32), with ages ranging from 6 to 8 weeks. The CDX models were created by subcutaneous administration of a tumor culture of human gastric adenocarcinoma (AGS) in a dose of 5 × 106 cells per mouse. After the tumors reaching a volume of 70–100 mm³, the animals were divided into four groups of eight individuals each, with the objective of ensuring minimal variation in the mean tumor node volume between groups. The efficacy of the therapeutic intervention was evaluated by measuring the inhibition of tumor growth (TGI %). The statistical data processing was performed using the Microsoft Excel 2013 and STATISTICA 12 software packages. The Mann–Whitney U test was utilized to evaluate the disparities between the experimental and control groups. Differences were considered statistically significant at p &lt; 0.05.Results. Consequently, subcutaneous CDX models of gastric adenocarcinoma were obtained. The study demonstrated that the administration of JO‑122(2) as a monotherapy did not result in a statistically significant impact on the growth of tumor nodes. The most significant antitumor activity was observed in the group administered combination therapy (JO‑122(2) + 5‑fluorouracil). The mean value of tumor node volumes at the conclusion of the experiment (on day 29 after the commencement of treatment) in this group was 513.98 ± 56.50 mm³, whereas in the control group it was 915.08 ± 49.93 mm³. A comparison of tumor growth rates between the groups receiving 5‑fluorouracil monotherapy and combination therapy revealed statistically significant differences as early as the 22nd day of the experiment. Furthermore, the highest TPO value was observed in the group administered the combination of drugs, at 43.83 %.Conclusion. The results demonstrated a more effective antitumor effect on gastric adenocarcinoma models when tropolone was used in combination with a cytostatic. This finding suggests the potential for further investigation into the properties of this compound and the possibility of extending its study.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>трополоны</kwd><kwd>CDX-модели</kwd><kwd>противоопухолевая активность</kwd><kwd>иммунодефицитные мыши</kwd><kwd>BALB/c Nude</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric cancer</kwd><kwd>tropolones</kwd><kwd>CDX model</kwd><kwd>antitumor activity</kwd><kwd>immunodeficient mice</kwd><kwd>BALB/c Nude</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">финансирование данной работы проводилось в рамках государственного задания «Поиск натуральных и синтетических вторичных метаболитов растений, обладающих противоопухолевыми и иммунокорригирующими свойствами на моделях in vitro и in vivo».</funding-statement><funding-statement xml:lang="en">funding for this work was provided within the framework of the state assignment “Search for natural and synthetic secondary plant metabolites with antitumor and immunoreactive properties in in vitro and in vivo models”.</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">Bray F, Laversanne M, Sung H, Ferlay J, Siegel RL, Soerjomataram I, Jemal A.
