title: Reversal of the antiviral activity of ribavirin against Sindbis virus in Ae. albopictus mosquito cells.
abstract: Earlier work in our laboratory has shown that the replication of Sindbis virus in Aedes albopictus mosquito cells is inhibited by ribavirin (Rbv) and mycophenolic acid (MPA) (Sarver and Stollar (1978) Virology 91, 267-282; Malinoski and Stollar (1980) Virology 102, 473-476). We report here that the antiviral effect of Rbv and MPA can be reversed by depriving infected cells of methionine or isoleucine, or by treating them with fluorodeoxyuridine (FUdR) or cycloleucine. We suggest that, as was the case when the antiviral activity of Rbv was reversed by actinomycin D (Malinoski and Stollar (1981a) Virology 110, 281-291), these effects may be mediated by changes in the GTP pools of treated cells.
