Hesperidin, a flavonoid glycoside, is a natural phenolic compound that has broad biological effects. Increasing evidence suggests that hesperidin inhibits the occurrence and development of neurodegenerative diseases, including Alzheimer's disease (AD). This article reviews the neuropharmacological mechanisms of hesperidin in the prevention and treatment of AD through in vitro and in vivo studies. A systematic review of preclinical studies was conducted using PubMed, Web of Science, Scopus, and Google Scholar (up to July 1, 2024). The neuroprotective potential of hesperidin was mediated through mechanisms such as inhibition of β-amyloid (Aβ) aggregation, enhancement of endogenous antioxidant defense functions, reduction of neuroinflammation and apoptosis, improvement of mitochondrial dysfunction, regulation of autophagy, and promotion of neurogenesis. Despite various preclinical studies on the role of hesperidin in AD, its exact effects on humans remain unclear. Few clinical trials have indicated that dietary supplements rich in hesperidin can improve cerebral blood flow, cognition, and memory performance. The neuroprotective effect of hesperidin may be exerted via regulating different molecular pathways, including the RAGE/NF-κB, Akt/Nrf2, and AMPK/BDNF/CREB pathways. However, further clinical trials are needed to confirm the neuroprotective effects of this natural flavonoid compound and to assess its safety.
橙皮苷是一种黄酮糖苷，是一种具有广泛生物学效应的天然酚类化合物。越来越多的证据表明，橙皮苷可抑制包括阿尔茨海默病（AD）在内的神经退行性疾病的发生和发展。本文通过体外和体内研究综述了橙皮苷在预防和治疗AD中的神经药理学机制。使用PubMed、Web of Science、Scopus和谷歌学术（截至2024年7月1日）对临床前研究进行了系统综述。橙皮苷的神经保护潜力是通过抑制β-淀粉样蛋白（Aβ）聚集、增强内源性抗氧化防御功能、减少神经炎症和细胞凋亡、改善线粒体功能障碍、调节自噬以及促进神经发生等机制介导的。尽管有各种关于橙皮苷在AD中作用的临床前研究，但其对人类的确切影响仍不清楚。少数临床试验表明，富含橙皮苷的膳食补充剂可以改善脑血流量、认知和记忆表现。橙皮苷的神经保护作用可能通过调节不同的分子途径来发挥，包括RAGE/NF-κB、Akt/Nrf2和AMPK/BDNF/CREB途径。然而，需要进一步的临床试验来证实这种天然黄酮类化合物的神经保护作用并评估其安全性。
