Inhibition of herpes simplex virus-induced DNA polymerase activity and viral DNA replication by 9-(2-hydroxyethoxymethyl)guanine and its triphosphate.

Abstract:

The effect of the nucleoside analog 9-(2-hydroxyethoxymethyl)guanine (acycloguanosine) on herpes simplex virus type 1 DNA synthesis was examined. Acycloguanosine inhibited herpesvirus DNA synthesis in virus-infected cells. The synthesis of host cell DNA was only partially inhibited in actively growing cells at acycloguanosine concentrations several hundred-fold greater than the 50% effective dose for herpes simplex virus type 1. Studies using partially purified enzymes revealed that the triphosphate of this compound inhibited the virus-induced DNA polymerases (DNA nucleotidyltransferases) to a greater degree than the DNA polymerase of the host cell, that the inhibition was dependent upon the base composition of the template, and that the triphosphate was a better substrate for the virus-induced polymerases than for the alpha cellular DNA polymerases.
