Рост числа лиц с ожирением сопряжен с распространением сердечно-сосудистых заболеваний, что обосновывает поиск новых средств для коррекции метаболических нарушений. Цель. Оценить метаболические эффекты производных ГАМК (композиции ФПС и МФБА) при раздельном и комбинированном применении с ситаглиптином на модели нарушения углеводного обмена, вызванного алиментарным ожирением.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование выполнено на крысах-самцах с алиментарным ожирением. После полугодовой высокожировой и высококалорийной диеты формировали 7 групп (n=8), включая группу позитивного (интактные крысы без ожирения) и негативного контроля, а также 5 сопоставимых по выраженности ожирения групп, получавших в течение 30 дней раздельно исследуемые композиции: МФБА (20 мг/кг) и ФПС (50 мг/кг), референтный препарат ситаглиптин (10 мг/кг), а также комбинации: МФБА+ситаглиптин (20+10 мг/кг), ФПС+ситаглиптин (50+10 мг/кг). По завершении курсового лечения оценивали изменение массы тела, массу висцерального жира, липидный профиль, выраженность углеводных нарушений на основе перорального теста на толерантность к глюкозе и теста толерантности к инсулину. Методом иммуноферментного анализа определяли уровень глюкагона, инсулина и глюкагоноподобного пептида-1 (ГПП-1). Оценка степени повреждения печени осуществлялась по уровню печеночных трансаминаз (АЛТ и АСТ) и при морфологическом исследовании структурных изменений.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что композиции МФБА и ФПС, раздельно и в комбинации с ситаглиптином, статистически значимо снижали массу тела и массу висцерального жира, усиливали гипогликемическое действие ситаглиптина (особенно в сочетании с ФПС). Раздельное, а также комбинированное с ситаглиптином введение МФБА и ФПС способствовало увеличению уровня ГПП-1 и инсулина, улучшению утилизации глюкозы и повышению чувствительности к инсулину, а также нормализации липидного профиля и уровней АЛТ, АСТ. При морфологическом исследовании на фоне лечения отмечалось меньшее число очагов лимфоидной инфильтрации и менее выраженная жировая дистрофия печени. Наибольшую эффективность проявила комбинация ФПС+ситаглиптин.</p></sec><sec><title>Заключение</title><p>Заключение. Производные ГАМК – МФБА и ФПС при монотерапии и более выраженно в комбинации с ситаглиптином уменьшали выраженность метаболических нарушений, связанных с ожирением. Отмеченное для циклического производного ГАМК (ФПС) анорексигенное действие и способность улучшать углеводный и липидный обмен представляет интерес для дальнейших исследований.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: The increase in the number of people with obesity is associated with an increase in the prevalence of cardiovascular diseases, justifying the search for new drugs to correct metabolic disorders.</p></sec><sec><title>AIM</title><p>AIM: To assess the metabolic effects of GABA derivatives (FPS and MFBA compositions) when used separately and in combination with sitagliptin in a model of carbohydrate metabolism disorder induced by alimentary obesity.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: The study was conducted on male rats with alimentary obesity. Following a six-month high-fat, high-calorie diet, seven groups were formed (n=8), including a positive control group (intact rats without obesity) and a negative control group, as well as five groups with comparable obesity severity. These groups received the studied compositions separately for 30 days: MFBA (20 mg/kg) and FPS (50 mg/kg), the reference drug sitagliptin (10 mg/kg), and combinations of MFBA+sitagliptin (20+10 mg/kg), FPS+sitagliptin (50+10 mg/kg). Upon completion of the treatment course, changes in body weight, visceral fat mass, lipid profile, and severity of carbohydrate disorders based on the oral glucose tolerance test and the insulin tolerance test were assessed. Levels of glucagon, insulin, and glucagon-like peptide-1 (GLP-1) were determined by enzyme-linked immunosorbent assay. The degree of liver damage was evaluated based on levels of liver transaminases (ALT and AST) and through morphological examination of structural changes.</p></sec><sec><title>RESULTS</title><p>RESULTS: It was established that the MFBA and FPS compositions, separately and in combination with sitagliptin, significantly reduced body weight and visceral fat mass, and enhanced the hypoglycemic action of sitagliptin (especially in combination with FPS). The separate and combined administration of MFBA and FPS with sitagliptin increased the levels of GLP-1 and insulin, improved glucose utilization, and increased insulin sensitivity, as well as normalized the lipid profile and levels of ALT, AST. Morphological examination revealed fewer foci of lymphoid infiltration and less pronounced fatty degeneration of the liver during treatment. The combination of FPS+sitagliptin showed the highest effectiveness.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: GABA derivatives - MFBA and FPS, in monotherapy and more pronouncedly in combination with sitagliptin, reduced the severity of metabolic disorders associated with obesity. The anorexigenic effect noted for the cyclic GABA derivative (FPS) and the ability to improve carbohydrate and lipid metabolism are of interest for further studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ожирение</kwd><kwd>алиментарное ожирение</kwd><kwd>производные ГАМК</kwd><kwd>ситаглиптин</kwd><kwd>крысы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>obesity</kwd><kwd>alimentary obesity</kwd><kwd>GABA derivatives</kwd><kwd>sitagliptin</kwd><kwd>rats</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта РНФ от 19 апреля 2021 №21-15-00192.</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">Koliaki C, Dalamaga M, Liatis S.
