Ganciclovir
Ganciclovir has also been used with some success in treating "Human herpesvirus 6" infections.
Herpes simplex research
Since the introduction of the nucleoside analogs decades ago, treatment of herpes simplex virus (HSV) infections has not seen much innovation, except for the development of their respective prodrugs (Aciclovir, Famciclovir, Valacilovir..). Drawbacks such as poor bioavailability or limited effectiveness of these drugs require further research effort of new pharmaceutical drugs against the herpes simplex disease. The inhibitors of the Helicase-primase complex of HSV represent a very innovative approach to the treatment of herpesvirus disease.
