Abstract

Background

Alpha-synuclein (α-syn) aggregates contribute to neuronal damage and many neurodegenerative disorders (NDs) which are known as α-synucleinopathies. Flavonoids are polyphenolic compounds extensively found in various plant-based food such as fruits and vegetables. They have potential benefits in human health, especially in α-synucleinopathy-associated NDs.

Objective

This review summarizes the latest scientific evidence on the impact of flavonoids on α-synucleinopathy, particularly in Parkinson’s disease

Methods

A comprehensive literature search of Web of Science, PubMed, Scopus and Google Scholar was performed to obtain relevant research studies reporting the anti- synucleinopathies effects of dietary flavonoids

Results

Baicalein, luteolin, quercetin, myricitrin, epigallocatechin-3-gallate and genistein are among the most effective flavonoids against synucleinopathies. The main mechanisms of action contributing to these effects are reducing α-syn production; preventing α-syn aggregation and reducing preformed aggregates; promoting degradation of intracellular α-syn aggregates through autophagy; modulating the activity/expression of antioxidant enzymes; and protecting dopaminergic neurons from oxidative damage and apoptosis

Conclusions

The results of this review highlighted the beneficial effects of flavonoids in the prevention and management of synucleinopathies. However, there is no clinical data that support these effects in humans, which emphasizes the necessity for designing clinical trials to investigate the efficacy, safe dosage, possible side effects and pharmacokinetics characteristics of flavonoids in humans.

膳食黄酮类化合物:靶向帕金森病α-突触核蛋白病的有前景的化合物
背景α-突触核蛋白(α-syn)聚集体导致神经元损伤和许多神经退行性疾病(ND),这些疾病被称为α-突触蛋白病。黄酮类化合物是多酚类化合物,广泛存在于各种植物性食品中,如水果和蔬菜。它们对人类健康有潜在的益处,特别是在α-突触核蛋白病相关的NDs中。目的本文综述了黄酮类化合物对α-突触蛋白病的影响,特别是对帕金森病的影响的最新科学证据,Scopus和Google Scholar进行了相关研究,报道了膳食黄酮类化合物的抗突触核蛋白病作用。导致这些效应的主要作用机制是减少α-syn的产生;防止α-syn聚集并减少预形成的聚集体;通过自噬促进细胞内α-syn聚集体的降解;调节抗氧化酶的活性/表达;以及保护多巴胺能神经元免受氧化损伤和凋亡。结论本综述的结果强调了黄酮类化合物在预防和治疗突触核蛋白疾病中的有益作用。然而,没有临床数据支持这些对人体的影响,这强调了设计临床试验以研究黄酮类化合物在人体中的疗效、安全剂量、可能的副作用和药代动力学特征的必要性。
