Abstract Parkinson's disease (PD) is a neurodegenerative disorder described by severe motor symptoms involving postural imbalance, uncontrolled shake, slowness of motion and rigidity. Searching for a natural remedy for PD to overcome the common adverse effects of conventional treatments, the neuroprotective effects of three dose levels (50, 100, and 200 mg/kg) of Pulicaria undulata essential oil (PUEO) in rotenone-induced model in male Wistar rats were investigated. PUEO was analyzed by GC and GC/MS resulting in the identification of twenty-one compounds. Carvotanacetone was the major component (80.14%). The middle and high doses of PUEO attenuated rotenone-induced behavioral deficits besides, hindering the decrease in striatal dopamine and ATP levels, with partial retardation in rotenone-induced body weight loss. Biochemical assessments illustrated that PUEO mitigated rotenone-induced increment in striatal interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and inducible nitric oxide synthase (iNOS). The reduction in malondialdehyde and increase in glutathione striatal contents depicted its antioxidant potential. Molecular docking study of carvotanacetone might justify the observed normalization of the elevated iNOS level induced after exposure to rotenone. This is the first study indicating the ability of PUEO to protect rats against rotenone-induced PD via anti-inflammatory and antioxidant activities with the ability to reduce α-synuclein gene expression.

蒲公英精油在大鼠帕金森病鱼藤酮模型中的神经保护作用:对其抗炎和抗氧化作用的洞察

摘要 帕金森病 (PD) 是一种神经退行性疾病,表现为严重的运动症状,包括姿势失衡、不受控制的颤抖、运动缓慢和僵硬。寻找 PD 的自然疗法,以克服常规治疗的常见不良反应,三种剂量水平(50、100 和 200 毫克/公斤)的蒲公英精油 (PUEO) 在鱼藤酮诱导的男性模型中的神经保护作用研究了 Wistar 大鼠。通过 GC 和 GC/MS 分析 PUEO,鉴定出 21 种化合物。香芹酮是主要成分(80.14%)。中高剂量的 PUEO 减轻了鱼藤酮引起的行为缺陷,此外,还阻碍了纹状体多巴胺和 ATP 水平的降低,部分延缓了鱼藤酮引起的体重减轻。生化评估表明,PUEO 减轻了鱼藤酮诱导的纹状体白细胞介素-1β (IL-1β)、肿瘤坏死因子-α (TNF-α) 和诱导型一氧化氮合酶 (iNOS) 的增加。丙二醛的减少和谷胱甘肽纹状体含量的增加描述了其抗氧化潜力。香芹酮的分子对接研究可能证明在暴露于鱼藤酮后所观察到的 iNOS 水平升高的正常化是合理的。这是第一项表明 PUEO 能够通过抗炎和抗氧化活性保护大鼠免受鱼藤酮诱导的 PD 的能力,并具有降低 α-突触核蛋白基因表达的能力。丙二醛的减少和谷胱甘肽纹状体含量的增加描述了其抗氧化潜力。香芹酮的分子对接研究可能证明在暴露于鱼藤酮后所观察到的 iNOS 水平升高的正常化是合理的。这是第一项表明 PUEO 能够通过抗炎和抗氧化活性保护大鼠免受鱼藤酮诱导的 PD 的能力,并具有降低 α-突触核蛋白基因表达的能力。丙二醛的减少和谷胱甘肽纹状体含量的增加描述了其抗氧化潜力。香芹酮的分子对接研究可能证明在暴露于鱼藤酮后所观察到的 iNOS 水平升高的正常化是合理的。这是第一项表明 PUEO 能够通过抗炎和抗氧化活性保护大鼠免受鱼藤酮诱导的 PD 的能力,并具有降低 α-突触核蛋白基因表达的能力。
