摘要
目的制备苦参素磷脂复合物并对其体外抗乙肝病毒活性进行评价。方法利用四氢呋喃作为反应溶剂,苦参素及磷脂溶于溶媒中,真空除去有机溶剂得苦参素磷脂复合物。并以2.2.15 cell line为细胞模型,分别对苦参素磷脂复合物的细胞毒性值和乙型肝炎表面抗原,乙型肝炎e抗原,乙型肝炎病毒DNA的抑制率进行了研究。结果制得的苦参素磷脂复合物中苦参素的含量为24.86%。苦参素磷脂复合物的细胞毒性值为250μg·mL-1。与苦参素相比,苦参素磷脂复合物对2.2.15细胞的HBsAg,HBeAg,HBV-DNA值明显降低。结论苦参素磷脂复合物能够产生更有效的抗乙肝病毒活性。因此乙肝治疗中苦参素磷脂复合物有很强的抗病毒活性潜力。
Aim The oxymatrine phospholipid complexs were prepared, and its activity against hepatitis B virus in vitro were studied. Methods Using tetrahydrofuran as a reaction medium, oxymatrine and phospholipids were resolved into the medium, Oxymatrine phospholipid eomplexs were prepared. The toxicity measurements and inhibitory effect on HBsAg, HBeAg, and HBVDNA of oxymatrine phospholipid complex in 2.2.15 cells were studied respectively. Results The content of oxymatrine in the phospholipids eomplexs prepared was 24,86% （W/W）. The TCO of the oxymatrine phospholipid eomplexs was 250 μmol·L^- 1 The inhibitory effect of HBsAg, HBeAg, HBV-DNA of 2.2.15 cells treated by oxymatrine phospholipid complex were higher than those of the oxymatrine. Conclusion Oxymatrine phospholipid complex can have stronger effective activity against hepatitis B virus compared with oxymatrine. So oxymatrine phospholipid eomplexs were showing its potential antiviral activity in hepatitis B treatment.
