Table 2. Antiviral Evaluation of Series 1 against EV-D68^a in RD Cells^b.

^aEV-D68 strain: STL-2014-12.

^bEC₅₀: concentration that effectively inhibited the cytopathic effect by 50% in Rhabdomyosarcoma cell lines (RD cells).

^cCC₅₀: concentration that inhibited the normal uninfected cell viability by 50%, or the maximum soluble concentration which started from 200 μM in serial 3-fold dilutions.

^dSelectivity index (SI) calculated as CC₅₀/EC₅₀ ratio.

^eNA: no activity.
