FIG. 3.

Nucleoside analogues are antiviral against PV and CVB3. HeLa cells were pretreated with nucleoside analogs (at 0.5 or 2 mM) for 1 h prior to infection with PV or CVB3 at an MOI of 5. Infection was allowed to proceed for 6 h, at which time cell-associated virus was collected and the titer was determined. Data were normalized such that the titer of control sample with no nucleoside treatment was set to a value of 100.
