Gastric ulcer is one of the most common chronic gastrointestinal diseases characterized by a significant defect in the mucosal barrier. The current study has been conducted to evaluate the brucine anti-ulcer effect. Brucine has binding energy values ranging from -2.99 to -8.11 kcal/mol against chosen targets, according to research. Brucine exhibits an inhibitory effect against . findings revealed that brucine (3 mg/kg) showed effective results in healing ethanol-induced ulcer lesions of the gastric region in rats. Brucine showed an inhibitory effect against H/K-ATPase. Levels of glutathione, glutathione-s-transferase, and catalase were enhanced in the gastric rat tissue with the use of brucine, while a significant decrease in lipid peroxide levels was seen. Histopathological evaluation showed improvement in cellular architecture and a decrease in inflammatory indicators like cyclooxygenase, tumor necrosis factor, and nuclear factor kappa B expression, validated through immunohistochemistry, enzyme-linked immunosorbent assay, and Western blot techniques. In the reverse transcription-polymerase chain reaction, brucine decreased H/K-ATPase mRNA levels. This study reveals that brucine possesses stable binding affinities against selected targets. Brucine exhibits an anti-ulcer effect, mediated anti-, H/K-ATPase inhibition, and antioxidant and anti-inflammatory pathways.
胃溃疡是最常见的慢性胃肠疾病之一,其特征是黏膜屏障存在显著缺陷。本研究旨在评估马钱子碱的抗溃疡作用。根据研究,马钱子碱对选定靶点的结合能值在-2.99至-8.11千卡/摩尔之间。马钱子碱对……表现出抑制作用。研究结果显示,马钱子碱(3毫克/千克)对大鼠胃区乙醇诱导的溃疡损伤愈合有显著效果。马钱子碱对H/K-ATP酶有抑制作用。使用马钱子碱后,大鼠胃组织中的谷胱甘肽、谷胱甘肽-S-转移酶和过氧化氢酶水平升高,而脂质过氧化物水平显著降低。组织病理学评估显示细胞结构有所改善,通过免疫组织化学、酶联免疫吸附测定和蛋白质印迹技术验证,环氧合酶、肿瘤坏死因子和核因子κB表达等炎症指标有所下降。在逆转录-聚合酶链反应中,马钱子碱降低了H/K-ATP酶mRNA水平。本研究表明,马钱子碱对选定靶点具有稳定的结合亲和力。马钱子碱通过抑制H/K-ATP酶以及抗氧化和抗炎途径发挥抗溃疡作用。
