title: [Antiviral activity and possible mechanisms of action of moraprenil phosphates during experimental infection caused by herpes simplex type 1 virus].
abstract: OBJECTIVE
  Study of antiviral activity of moraprenil phosphates (MPP) against herpes simplex type 1 virus (HSV1) in vitro and during experimental infection caused by HSV1 in mice.
  
  
  METHODS
  Activity of MPP in vitro was tested by the ability to suppress formation of symplasts in VERO cells infected with HSV1, strain VR-3. A series of MPP that suppress virus-induced symplast-formation by 30 times was selected for in vivo experiments. Anti-viral activity of MPP in vivo was studied in HSV-1 infected mice after administration of either prophylaxis or therapy regimens.
  
  
  RESULTS
  MPP at the dose of 20 microg/mice during s/c administration exhibited a pronounced prophylactic-therapeutic effect. Effectiveness of MPP during clinically evident herpes against the background of developing neurologic symptoms was demonstrated for the first time. Visual observation of the mice, that had received MPP as the first clinical symptoms of the disease appeared, has shown that against the background of preparation injection the clinical signs have ceased after 2 - 3 days and did not registered at least for the whole duration of the observation period (14 days).
  
  
  CONCLUSIONS
  Active herpes infection is accompanied by the increase of FoxP3 expression in-thymus was shown. Possible mechanisms of anti-viral effect of MPP are discussed.
