Abstract

Eugeniin exhibits antiviral activity against acyclovir and phosphonoacetic acid (PAA)-resistant herpes simplex virus type 1 (HSV-1) as well as the wild-type HSV-1 in vitro. In this study, we characterized the biological activity of eugeniin in cutaneously HSV-1-infected mice and its interaction with HSV-1 DNA polymerase. The oral and intraperitoneal administrations of eugeniin at 0.3 mg/kg showed similar therapeutic efficacy in retarding the development of skin lesions of HSV-1-infected mice. The two routes of administration at 6 or 50 mg/kg significantly prolonged the mean survival times and/or reduced mortality without toxicity. The oral administration of eugeniin at 50 mg/kg reduced virus yields in the skin and brain of infected mice. Thus, the therapeutic efficacy of oral administration at the various doses of eugeniin was similar to that of intraperitoneal administration, suggesting that the oral bioavailability of eugeniin was high with respect to absorption. Furthermore, the anti-HSV-1 activity of eugeniin was characterized by isobolograms analyzing its combined effects with acyclovir or PAA in HSV-1-infected Vero cells. Eugeniin enhanced the anti-HSV-1 activity of acyclovir but was suggested to be antagonistic with PAA. The interaction of eugeniin and PAA on the activity of partially purified HSV-1 DNA polymerase suggested that eugeniin interacted with the polymerase in the vicinity of PAA-binding site. Thus, eugeniin showed different anti-HSV-1 action from acyclovir and PAA and therapeutic anti-HSV-1 activity in mice.

Abstract

The hot-water extract of Geum japonicum has been shown to exhibit prophylactic and therapeutic anti-herpes simplex virus (HSV) activity in murine infection models. Eugeniin was purified as an anti-HSV compound from the extract and also was isolated from another herbal extract (Syzygium aromaticum) that had exhibited anti-HSV activity in mice. Thus the anti-HSV action of eugeniin was characterized. The effective concentration (5.0 microg/ml) for 50% plaque reduction of eugeniin for wild HSV type 1 (HSV-1) on Vero cells was 13.9-fold lower than its 50% cytotoxic concentration determined by a yield-reduction assay. Eugeniin also inhibited the growth of acyclovir-phosphonoacetic acid-resistant HSV-1, thymidine kinase-deficient HSV-1 and wild HSV type 2. Eugeniin as well as phosphonoacetic acid inhibited viral DNA and late viral protein syntheses in their infected Vero cells, but not cellular protein synthesis at its inhibitory concentrations. Purified HSV-1 DNA polymerase activity was inhibited by eugeniin noncompetitively with respect to dTTP. Its apparent Ki value for euginiin was 8.2- and 5. 8-fold lower than the Ki values of purified human DNA polymerases alpha and beta, respectively. Thus one of the major target sites of inhibitory action of eugeniin is viral DNA synthesis; the inhibitory action for viral DNA polymerase activity was novel compared with anti-HSV nucleoside analogs.
