Abstract

In order to find less toxic antiviral agents from Basidiomycetes, EA, the water soluble substance, was prepared from the carpophores of Elfvingia applanata (Pers.) Karst. Antiviral activity of EA against vesicular stomatitis virus [New Jersey serotype, VSV(NJ)] was examined in Vero cells using plaque reduction assay in vitro. And the combined antiviral effects of EA with interferon (IFN) alpha and gamma were examined on the multiplication of VSV(NJ). EA caused a concentration-dependent reduction in the plaque formation of VSV(NJ) with 50% effective concentration $(EC_{50})$ of 2.10 mg/ml. The results of combination assay were evaluated by the combination index (CI) that was analysed by the multiple drug effect analysis. The combination of EA with IFN alpha showed more potent effect with CI values of $0.87{\sim}1.59$ for 50%, 70% and 90% effective levels than that with INF gamma with CI values of $1.05{\sim}2.03$.

잔나비걸상 Elfvingia applananta 자실체의 수용성물질 EA의 vesicular stomatitis virus[New Jersey serotype, VSV(NJ)]에 대한 항바이러스효과를 plaque reduction assay에 따라 실험한 결과 EA는 용량의존적으로 plaque 형성을 억제하였으며 $EC_{50}$는 2.10 mg/ml이었다. 단백질성 항바이러스제인 interferon(IFN)과 EA와의 병용시험 결과 f(a)가 0.50에서 0.90인 유효농도범위에서 IFN alpha와 병용시 f(a)의 값이 커짐에 따라 상가작용 내지는 길항작용을 나타내었으며, IFN gamma와의 병용시에는 길항작용을 나타내었다. 따라서 IFN alpha와의 병용시 f(a)가 0.50내지 0.70의 유효농도 범위에서 상가효과가 있다.
