Eprociclovir (A5021, 9-[[cis-1', 2'-bis(hydroxymethyl)cycloprop-1'-yl]methyl]guanine) is a nucleoside analog with antiviral activity. Antiviral activity of eprociclovir appears to depend rapid and stable accumulation of its triphosphate in infected cells and on inhibition of viral DNA polymerase by its triphosphate. Eprociclovir was shown to be a potent inhibitor of the replication of herpes simplex virus type 1, 2, 6, Epstein-Barr virus and varicella zoster virus, both in vitro and in vivo. Eprociclovir development has been discontinued.
