Abstract：
:The purpose of this study was to investigate the in vitro antiviral properties of pterocarnin A, extracted from the bark of Pterocarya stenoptera (Juylandaceae). Results showed that pterocarnin A exhibited anti-herpes simplex virus (HSV) activity. It had a low selectivity index (SI) value and only possessed some level of cell cytotoxic effect at high antiviral concentrations. Mechanism studies demonstrated that pterocarnin A inhibited herpes simplex virus type 2 (HSV-2) from attaching and penetrating into cells. It also actively suppressed HSV-2 multiplication in Vero cells even when added 12 h after infection. This observation indicated that pterocarnin A affected the late stage(s) of HSV-2 infection cycle. Pterocarnin A also significantly reduced viral infectivity at high concentrations. From these observations, it was concluded that pterocarnin A suppressed both early and late in the replication cycle of HSV-2. The various modes of action of pterocarnin A in interfering with certain steps of viral infection thus merit further investigation.
