Ganciclovir
Ganciclovir has also been used with some success in treating "Human herpesvirus 6" infections.
Human herpesvirus 6
HHV-6’s replication results in the formation of concatemers, which are long molecules that contain several repeats of a DNA sequence. These long concatemers are then cleaved between the pac-1 and pac-2 regions by ribozymes for packaging of the genome into individual virions.
