Table 1.

Cytotoxicity and antiviral activity of EO and THQ.

Compound	CC₅₀ (µg/mL) ^a	IC₅₀ (µg/mL) ^b	SI ^c
EO	475 ± 48	38 ± 4.2	12.5
THQ	410 ± 46	45 ± 7.5	9.1

Cytotoxic concentration (CC₅₀) and inhibitory concentration (IC₅₀) were obtained by performing nonlinear regression followed by the construction of the sigmoidal concentration–response curves from Figure 1 and Figure 2A,B. ^a Concentration that inhibited cell viability by 50%; ^b Concentration that inhibited infection by 50%; ^c Selectivity index (CC₅₀/IC₅₀).
