Abstract

The increasing rates of morbidity and mortality owing to bacterial infections, particularly have necessitated finding solutions to face this issue. Thus, we elucidated the phytochemical constituents and antibacterial potential of extract (CDE). Using LC-ESI-MS/MS, the main phytoconstituents of CDE were explored, which were kaempferol-3,7--bis-alpha-L-rhamnoside, isorhamnetin, cyanidin-3-glucoside, kaempferide, kaempferol-3--alpha-L-rhamnoside, caffeic acid, isoquercitrin, quinic acid, isocitrate, mannitol, apigenin, acacetin, and naringenin. The CDE exerted an antibacterial action on isolates with minimum inhibitory concentrations ranging from 128 to 512 µg/mL. Also, CDE exhibited antibiofilm action using a crystal violet assay. A scanning electron microscope was employed to illuminate the effect of CDE on biofilm formation, and it considerably diminished cell number in the biofilm. Moreover, qRT-PCR was performed to study the effect of CDE on biofilm gene expression (, A, and A). The CDE revealed a downregulating effect on the studied biofilm genes in 43.48% of isolates. Regarding the model, CDE significantly decreased the burden in the liver and spleen of CDE-treated mice. Also, it significantly improved the mice's survival and substantially decreased the inflammatory markers (interleukin one beta and interleukin six) in the studied tissues. Furthermore, CDE has improved the histology and tumor necrosis factor alpha immunohistochemistry in the liver and spleen of the CDE-treated group. Thus, CDE could be considered a promising candidate for future antimicrobial drug discovery studies.

摘要

由于细菌感染导致的发病率和死亡率不断上升,尤其是(此处原文表述不完整),这就需要找到应对这一问题的解决方案。因此,我们阐明了(某种提取物名称未完整给出)提取物(CDE)的植物化学成分和抗菌潜力。使用液相色谱-电喷雾串联质谱法(LC-ESI-MS/MS),探究了CDE的主要植物成分,它们是山奈酚-3,7-二-α-L-鼠李糖苷、异鼠李素、矢车菊素-3-葡萄糖苷、山奈酚苷元、山奈酚-3-α-L-鼠李糖苷、咖啡酸、异槲皮苷、奎宁酸、异柠檬酸、甘露醇、芹菜素、刺槐素和柚皮素。CDE对(此处原文表述不完整)分离株具有抗菌作用,最低抑菌浓度范围为128至512μg/mL。此外,CDE通过结晶紫测定法表现出抗生物膜作用。使用扫描电子显微镜来阐明CDE对生物膜形成的影响,它显著减少了生物膜中的(此处原文表述不完整)细胞数量。此外,进行了定量逆转录聚合酶链反应(qRT-PCR)以研究CDE对生物膜基因表达(此处原文表述不完整)的影响。CDE在43.48%的(此处原文表述不完整)分离株中显示出对所研究的生物膜基因的下调作用。关于(此处原文表述不完整)模型中,CDE显著降低了经CDE处理的小鼠肝脏和脾脏中的(此处原文表述不完整)负担。此外,它显著提高了小鼠的存活率,并大幅降低了所研究组织中的炎症标志物(白细胞介素-1β和白细胞介素-6)。此外,CDE改善了CDE处理组小鼠肝脏和脾脏的组织学以及肿瘤坏死因子-α免疫组织化学。因此,CDE可被视为未来抗菌药物发现研究的一个有前景的候选物。
