Antiviral activity of selected nucleoside analogues against human herpes virus type 6

Abstract HHV-6 was evaluated in vitro for its susceptibility to a broad range of nucleoside analogues. PFA and several acyclic nucleoside phophonates emerged as the most potent inhibitors of HHV-6 replication as monitored by a newly developed immunofluorescence / flow cytometric assay as well as by microscopical evaluation of their inhibitory effect on HHV-6-induced cytopathogenicity.
