In this current study, we explored the preventive capacity of the aqueous extract of (OF), a root holoparasite, against CCl prompt hepatotoxicity in rats. LC-MS/MS profiling revealed the existence of 32 compounds belonging to organic acids, benzoic acid derivatives, and hydroxycinnamic acids along with their glycosides and derivatives as well as several flavonoids. , OF demonstrated substantial antioxidant potential at DPPH and ABTS assays. Results showed that the pretreatment with OF for 6 weeks at the doses (25 mg/kg bw) and (50 mg/kg bw) countered the CCl-induced liver injury by restoring liver injuries indicators (ALT, AST, LDH, ALP, GGT and bilirubin), normalizing lipid profile (TC, TG, LDL-C, and HDL-C), as well as, impeding DNA fragmentation. Furthermore, OF blocked the hepatic oxidative stress spurred by CCl administration through boosting antioxidant enzymes (GSH, CAT, and SOD) responsible of diminishing lipid peroxidation. exhibited an anti-inflammatory effect by downregulating TNF-α and IL-6 levels. OF suppressive effect on proinflammatory cytokines is further exerted by its capacity to modulate the expression of the NF-κB gene. investigation revealed that among the 32 identified compounds, vanillic acid glucoside and dihydroxybenzoic acid glucoside have strong and stable bindings with the active sites of three key inflammatory proteins (PARP-1, TNF-α, IL-6), which could highlight the antioxidant and anti-inflammatory capacity of. Overall, this research provides a preliminary pharmacological support for the medicinal applications of for addressing inflammatory and hepato-pathological conditions.
在本项研究中,我们探究了根全寄生植物(OF)水提取物对大鼠四氯化碳诱发的肝毒性的预防能力。液相色谱-串联质谱(LC-MS/MS)分析表明存在32种化合物,属于有机酸、苯甲酸衍生物、羟基肉桂酸及其糖苷和衍生物以及几种黄酮类化合物。此外,OF在二苯基苦味酰基自由基(DPPH)和2,2'-联氮-双-3-乙基苯并噻唑啉-6-磺酸(ABTS)测定中表现出显著的抗氧化潜力。结果显示,以(25毫克/千克体重)和(50毫克/千克体重)的剂量用OF预处理6周可通过恢复肝损伤指标(谷丙转氨酶、谷草转氨酶、乳酸脱氢酶、碱性磷酸酶、γ-谷氨酰转肽酶和胆红素)、使血脂谱(总胆固醇、甘油三酯、低密度脂蛋白胆固醇和高密度脂蛋白胆固醇)正常化以及阻止DNA片段化来对抗四氯化碳诱导的肝损伤。此外,OF通过增强负责减少脂质过氧化的抗氧化酶(谷胱甘肽、过氧化氢酶和超氧化物歧化酶)来阻断四氯化碳给药引发的肝脏氧化应激。通过下调肿瘤坏死因子-α(TNF-α)和白细胞介素-6(IL-6)水平表现出抗炎作用。OF对促炎细胞因子的抑制作用还通过其调节核因子-κB(NF-κB)基因表达的能力进一步发挥。调查显示,在这32种已鉴定的化合物中,香草酸葡萄糖苷和二羟基苯甲酸葡萄糖苷与三种关键炎症蛋白(聚(ADP-核糖)聚合酶-1、TNF-α、IL-6)的活性位点具有强而稳定的结合,这可能突出了OF的抗氧化和抗炎能力。总体而言,本研究为OF在治疗炎症和肝脏病理状况方面的药用应用提供了初步的药理学支持。
