Antiviral effect of chinonin against herpes simplex virus

In order to investigate the antiviral effect of chinonin against Herpes simplex virus (HSV), the encephalitis model in mice and skin infection model in guinea pigs were established by HSV- I and HSV-II infection respectively. Acyclovir was used as the positive reference drug to evaluate the antiviral capacity of chinonin. Chinonin showed an obvious therapeutic effect on encephalitis in mice at doses of 25 and 50 mg/kg. At both dosages, chinonin demonstrated stronger protection than acyclovir (1 and 5 mg/kg) to the infected mice from death. It was also found that chinonin could treat the skin infection in guinea pigs effectively. The therapeutic effect of chinonin was similar to that of acyclovir (5 mg/kg) at 25 mg/kg but obviously better than that at 50 and 75 mg/ kg. In conclusion, chinonin is a potential candidate for the treatment against HSV.
