The search for new therapies, derived from natural compounds in order to prevent and treat Parkinson's disease (PD) has aroused the interest of many researchers. Spondias mombin (L) has active constituents with known antioxidant and anti-inflammatory activities. The aim of this study was to evaluate the neuroprotective potential of the hexane extract of S. mombin (EHSm) in an experimental model of DP induced by rotenone in zebrafish. The analysis of GC/MS demonstrated cyclogallipharaol (13.88%) and dl-α-tocopherol (8.08%) mostly, while HPLC-DAD indicated the presence of quercetin (<5), quercetrin (6.54 mg/g) and rutin (8.83 mg/g). The zebrafish exposed for 4 weeks to rotenone (ROT, 3 μg/L) and EHSm (5, 15, 25 mg/L). EHSm (25 mg/L) was able to reverse the behavioral damage induced by ROT in the entries and time spent in the top area of the tank. The parameters biochemicals indicated of EHSm prevented oxidative stress (TBARS e total thiols), inflammation and dopamine uptake triggered by ROT, evidenced of increased on the CAT, SOD and GSH and decreased of GST, O production and NADPH oxidase activities. We conclude that EHSm demonstrate a neuroprotector effect mediated through anxiolytic and antioxidant activities. However, more studies are necessary to elucidate the exact mechanism underlying the effects of EHSm on DP induced by rotenone in zebrafish.
为了预防和治疗帕金森病(PD),人们一直在寻找新的治疗方法,这些方法源自天然化合物。Spondias mombin(L)具有已知的抗氧化和抗炎活性的活性成分。本研究旨在评估罗替戈汀诱导的斑马鱼 DP 模型中 Spondias mombin(L)的己烷提取物(EHSm)的神经保护潜力。GC/MS 分析表明,cyclogallipharaol(13.88%)和 dl-α-生育酚(8.08%)居多,而 HPLC-DAD 则表明槲皮素(<5)、槲皮苷(6.54 mg/g)和芦丁(8.83 mg/g)的存在。斑马鱼连续 4 周暴露于鱼藤酮(ROT,3μg/L)和 EHSm(5、15、25mg/L)。EHSm(25mg/L)能够逆转 ROT 引起的斑马鱼进入和停留在水箱顶部区域的行为损伤。EHSm 防止 ROT 引起的生物化学参数氧化应激(TBARS 和总巯基)、炎症和多巴胺摄取,CAT、SOD 和 GSH 增加,GST、O 产生和 NADPH 氧化酶活性降低,这表明其具有神经保护作用。我们得出结论,EHSm 表现出通过抗焦虑和抗氧化活性介导的神经保护作用。然而,需要进一步的研究来阐明 EHSm 对鱼藤酮诱导的斑马鱼 DP 的作用的确切机制。
