Preparation and Drug Release Properties of Berberine-Loaded Hollow Mesoporous Silica Nanoparticles

    摘要
  • 摘要: 利用苯乙烯为模板成功制备了具有良好水溶性的聚乙二醇功能化中空介孔纳米硅球，利用红外光谱、热重、动态光散射及透射电镜对其进行表征.该载体对小檗碱的载药量及包载率高达136.4 mg/g和68.2%.体外研究结果显示，24 h累积释放率约43.2%，细胞存活率均在80%以上.体内代谢结果显示，纳米载体药物使血药浓度显著提高.

     

    Abstract: Polyethylene glycol functionalized hollow mesoporous silica nanoparticles (HMS-PEG) with good water solubility were successfully prepared using styrene as template, and characterized by infrared spectroscopy, thermogravimetry, dynamic light scattering and transmission electron microscopy.The drug loading rate and entrapment rate of berberine based on HMS-PEG were as high as 136.4 mg/g and 68.2%, respectively.The results of vitro showed that the cumulative release rate was about 43.2% within 24 h, and the cell survival rate was above 80%.The metabolism results in vivo showed that nano-carrier drugs significantly increased BBR concentration in mouse plasma.
