【摘要】:目的探討河蚌多糖(AP)體外抗乙肝病毒(HBV)的生物活性及量效關(guān)系。方法以Hep G2.2.15細(xì)胞為體外細(xì)胞模型,與1:10梯度稀釋的AP 37℃孵育9d,ELISA法檢測(cè)細(xì)胞上清中HBsAg、HBeAg的含量,熒光定量PCR檢測(cè)HBV DNA載量。采用Thiele型連分式插值法檢測(cè)AP半數(shù)抑制濃度(IC_(50))、最大抑制率并繪制量效曲線圖。結(jié)果 AP在體外可顯著抑制Hep G2.2.15細(xì)胞的HBsAg和HBeAg分泌以及HBV DNA復(fù)制,且呈現(xiàn)劑量依賴關(guān)系。通過(guò)Thiele型連分式插值法得出量效關(guān)系表達(dá)式,并由此確定AP對(duì)HBeAg和HBsAg分泌的最大抑制率分別為47.7%和56.4%(抑制HBeAg的IC_(50)為143.7mg/L);對(duì)HBV DNA復(fù)制的最大抑制率為17.8%。結(jié)論 AP具有體外抗HBV生物活性。Thiele型連分式插值法簡(jiǎn)單、實(shí)用,是一種分析藥物活性的新方法。
