植物天然产物的神经保护机制及其靶向递送研究进展

神经退行性疾病给人们的健康和生活带来很大的不良影响.随着世界人口老龄化程度的加深,其发病率逐年攀升.植物天然产物种类丰富、来源广泛且安全性高,许多表现出抗氧化、抗炎、调节自噬等多种生物活性.随着对植物中天然产物提取方法、组成结构及功能活性研究的不断深入,发现其中许多物质,如黄酮、多糖、多肽等可以通过缓解氧化应激,调节细胞因子水平,调节自噬流量,抑制兴奋性毒性等来改善脑缺血、中风、阿尔兹海默、脊髓小脑萎缩等多种神经退行性疾病,在细胞及动物水平研究中表现出显著的神经保护作用,可作为预防和缓解神经系统疾病的潜在神经保护剂.然而,由于大多数植物天然产物的生物利用度低,血脑屏障通透性差,不能有效渗透血脑屏障靶向特异性区域,未达到发挥功效的浓度,因此需要借助外泌体、纳米颗粒等载体将其递送到大脑特定区域发挥作用.本文围绕食品中植物天然产物的神经保护机制及其靶向递送系统展开论述,以期为植物天然产物的进一步研究与应用提供帮助.
Advances in Neuroprotective Mechanisms and Targeted Delivery of Plant Natural Products
Neurodegenerative diseases have a great negative impact on people's health and life.With the increase of the aging degree of the world population,its incidence rate is rising year by year.There are a variety of plant natural prod-ucts,which have various biological activities,such as antioxidant,anti-inflammatory,regulating autophagy,etc.,and are characterized by wide sources and high safety.With the further research on the extraction method,composition,structure and functional activity of natural products in plants,it has been found that many of them,such as flavonoids,polysac-charides and peptides,can improve many neurodegenerative diseases such as cerebral ischemia,stroke,Alzheimer's dis-ease,spinocerebellar atrophy and so on by alleviating oxidative stress,regulating cytokine levels,regulating autophagic flow,and inhibiting excitatory toxicity.Studies in cells and animals have shown significant neuroprotective effects,which can be used as a potential neuroprotective agent to prevent and relieve nervous system diseases.Due to the low bioavail-ability and poor permeability of the blood-brain barrier,most plant natural products cannot effectively penetrate the blood-brain barrier to target specific areas to achieve therapeutic concentration of the disease,so it is necessary to use exosomes,nanoparticles and other carriers to deliver them to the diseased areas of the brain to play a role.The neuro-protection mechanism and targeted delivery system of plant natural products in food were discussed in order to provide help for the further research and application of plant natural products.
