Selective antiviral agents. The metabolism of 5-propyl-2'-deoxyuridine and effects on DNA synthesis in herpes simplex virus type 1 infections.

Abstract

The metabolism and disposition of 5-propyl-2'-deoxyuridine (Pr-dUrd) in herpes simplex virus type 1 infections were investigated in cell culture using [14C]Pr-dUrd, [32P]orthophosphate, and several methods including high pressure liquid chromatography and isopycnic centrifugation. Results in infected cells indicate Pr-dUrd 1) is taken up and phosphorylated to mono-, di-, and triphosphates; 2) is incorporated into DNA; 3) preferentially inhibits synthesis of viral DNA; 4) blocks re-initiation of viral DNA synthesis even after removal of the nucleoside from the culture; and 5) exerts these effects early in the course of infection (before 6 h postinfection). Pr-dUrd was not phosphorylated in uninfected cells, and had little or no effect on apparent cellular DNA synthesis in infected or uninfected cells. Present evidence suggests one possible antiviral event could be the lethal effect of Pr-dUrd after incorporation into viral DNA by alteration of DNA template-directed functions such as replication.
