The data are presented as an average of eight repetitions (n) ± standard error of the mean (SEM). The data were analyzed by one-way ANOVA with Duncan’s post hoc test (P ˃ 0.05) as indicated by the superscript letters. The letters indicate the differences between the groups within one assay. Statistically significant levels are denoted with different letters. The data are presented as the concentration (µM) that (i) halved the cell viability (IC50) or (ii) reduced 90% of cell viability (MIC).
