透明质酸疏水自组装纳米粒的制备及其负载虎杖苷的抗氧化活性研究
Preparation of hydrophobic self-assembled hyaluronic acid-based nanoparticles and study on their antioxidant activity in loading with polydatin
通过透明质酸与硬脂酸的酯化反应合成透明质酸硬脂酸酯(HASA)。采用薄膜水化法制备HASA空白与载药纳米粒,将虎杖苷包入纳米粒中,通过引入薄荷醇提高纳米粒跨越血脑屏障能力,最终制备出HASA/PD-Men。利用透射电镜(TEM)、粒度仪对空白纳米粒和HASA/PD-Men的形态及粒径进行分析,并利用HT22细胞模型考察了纳米粒对细胞存活率的影响。结果表明,HASA/PD-Men在1 μmol/L浓度下不具有细胞毒性,且在相同浓度下显著上调了抗氧化基因Nrf2、SOD和HO-1的表达,显示出较强的抗氧化和神经保护潜力。HASA/PD-Men在保护神经细胞以及治疗脑部疾病中具有潜在的应用价值。
Hyaluronic acid stearate (HASA) is synthesized through the esterification between hyaluronic acid and stearic acid.HASA blank and drug-loaded nanoparticles are prepared via thin film hydration method.Polydatin is encapsulated into the nanoparticles,and the ability of the nanoparticles to cross the blood-brain barrier is improved by adding menthol,and finally HASA/PD-Men are prepared.The morphology and particle size of blank HASA nanoparticles and HASA/PD-Men are analyzed by means of transmission electron microscopy (TEM) and particle size analyzer,and the influence of nanoparticles on cell survival rate is evaluated by using HT22 cell model.Results show that HASA/PD-Men has not cytotoxicity at 1 μmol/L,and significantly regulates up the expression of antioxidant genes such as Nrf2,SOD and HO-1 at the same concentration,showing strong antioxidant and neuro-protection potential.HASA/PD-Men has potential applications in the protection of nerve cells and the treatment of brain diseases.
