Abstract:
:As part of our studies on the molecular basis for the antiherpes activity of 5'-AdThd (5'-amino-5'-deoxythymidine), a study of the HSV-1 DNA synthesized in infected Vero cells exposed to 5'-AdThd was undertaken. Unlike many other antiviral nucleoside analogs, 5'-AdThd did not inhibit HSV-1 DNA synthesis. Analysis of the DNA synthesized in the presence of [14C]5'-AdThd revealed that the analog was incorporated into the viral DNA in a dose-dependent manner and that the degree of incorporation correlated with the antiviral activity as measured by yield reduction assays. Analysis of the 5'-AdThd substituted DNA by centrifugation in neutral and alkaline sucrose gradients revealed no double-stranded breaks but an increase in single-stranded breaks, at very high concentrations of the analog. Analysis of HSV-1-specific RNAs revealed a shift from poly(A+) to poly(A-) RNA. The degree of this shift paralleled the substitution of 5'-AdThd for thymidine in the HSV-1 DNA.
