摘　　要：为了从中草药中找到抗HBV的有效药物,利用BIA技术分析比较中药复方KA-01及其组成部分A、B、C、D对HBsAg和HBeAg蛋白结合的作用,应用HepG2.2.15细胞模型,激光扫描共聚焦显微技术研究了KA-01及其主要组分体外抑制HBV蛋白分泌的活性.结果显示,KA-01、A、B、C和D与HBsAg蛋白结合的响应值分别为200、183.7、162.1、39.1、66.6 RU,与HBeAg蛋白结合很少.KA-01对HepG2.2.15细胞分泌HBsAg和HBeAg的抑制率分别为62.01%和30.59%,A对HepG2.2.15细胞分泌HBsAg和HBeAg的抑制率分别为54.26%和14.15%,B对HepG2.2.15细胞分泌HBsAg和HBeAg的抑制率分别为50.97%和27.92%,C对HepG2.2.15细胞分泌HBsAg和HBeAg的抑制率分别为17.54%和8.06%.KA-01,A,B体外具有抗HBV活性.Abstract:In order to discover activated ingredient form Chinese herbal medicine and to bind KA-01and its main ingredients to HBsAg and HBeAg protein in CM5 by BIAcore 3000,the HepG2.2.15 cell was cultured in vitro to observe the inhibitory effect of KA-01 and its main ingredient.The inhibitory effect of KA-01 and its main ingredients on protein secretion of HBV were tested by Laser Confocal Microscope.The results indicated that the value of KA-01and its main ingredients of A、B、C、D binding with HBsAg protein...
