A neurodegenerative disorder (ND) refers to Huntington's disease (HD) which affects memory loss, weight loss, and movement dysfunctions such as chorea and dystonia. In the striatum and brain, HD most typically impacts medium-spiny neurons. Molecular genetics, excitotoxicity, oxidative stress (OS), mitochondrial, and metabolic dysfunction are a few of the theories advanced to explicit the pathophysiology of neuronal damage and cell death. Numerous in-depth studies of the literature have supported the therapeutic advantages of natural products in HD experimental models and other treatment approaches. This article briefly discusses the neuroprotective impacts of natural compounds against HD models. The ability of the discovered natural compounds to suppress HD was tested using either in vitro or in vivo models. Many bioactive compounds considerably lessened the memory loss and motor coordination brought on by 3-nitropropionic acid (3-NP). Reduced lipid peroxidation, increased endogenous enzymatic antioxidants, reduced acetylcholinesterase activity, and enhanced mitochondrial energy generation have profoundly decreased the biochemical change. It is significant since histology showed that therapy with particular natural compounds lessened damage to the striatum caused by 3-NP. Moreover, natural products displayed varying degrees of neuroprotection in preclinical HD studies because of their antioxidant and anti-inflammatory properties, maintenance of mitochondrial function, activation of autophagy, and inhibition of apoptosis. This study highlighted about the importance of bioactive compounds and their semi-synthetic molecules in the treatment and prevention of HD.
神经退行性疾病(ND)指的是亨廷顿舞蹈症(HD),它会导致记忆丧失、体重减轻以及舞蹈症和肌张力障碍等运动功能障碍。在纹状体和大脑中,HD最典型地影响中等棘状神经元。分子遗传学、兴奋性毒性、氧化应激(OS)、线粒体和代谢功能障碍是为解释神经元损伤和细胞死亡的病理生理学而提出的一些理论。对文献的大量深入研究支持了天然产物在HD实验模型和其他治疗方法中的治疗优势。本文简要讨论了天然化合物对HD模型的神经保护作用。使用体外或体内模型测试了所发现的天然化合物抑制HD的能力。许多生物活性化合物显著减轻了3-硝基丙酸(3-NP)引起的记忆丧失和运动协调障碍。脂质过氧化减少、内源性酶抗氧化剂增加、乙酰胆碱酯酶活性降低以及线粒体能量生成增强,都极大地减少了生化变化。这很重要,因为组织学表明,用特定天然化合物进行治疗可减轻3-NP对纹状体的损伤。此外,由于天然产物具有抗氧化和抗炎特性、维持线粒体功能、激活自噬以及抑制细胞凋亡,它们在临床前HD研究中显示出不同程度的神经保护作用。这项研究强调了生物活性化合物及其半合成分子在治疗和预防HD方面的重要性。
