↵a M2-S31N channel inhibition was measured using two-electrode voltage clamp assay as described (Wang et al., 2013b; Wu et al., 2014). The data are expressed as percentage inhibition at 100/30 µM compound concentration.
↵b Reported in Wang et al. (2013b).
↵c Reported in Wu et al. (2014).
↵d EC50 in plaque assays was determined with the A/WSN/33 (H1N1) virus.
↵e EC50 in CPE assay was determined with the A/WSN/33 (H1N1) virus using MTT.
↵f CC50 was assayed using MTT after incubating MDCK cells with increasing concentrations of compounds for 72 hours.
↵g SI was calculated by dividing CC50 values over plaque assay EC50 values.
