Antiviral activities of lycorine analogues

^aCC₅₀ values were derived from Vero cells using an MTT assay.

^bEC₅₀ values were derived from viral titer reduction assays. Vero cells were infected with WNV (0.1 MOI) in the presence of various concentrations of each compound. Viral titers at 42 h p.i. were determined by plaque assays, as described in Materials and methods.
