Means ± standard deviation (SD) of histidine revertant colonies, mutagenic index (MI), and inhibition percentage (IP) of mutagenicity for two tester strains of <i>Salmonella typhimurium</i>, TA98 and TA100, after treatment with different doses of sulfonamide chalcone N-{4-[3-(4-nitrophenyl)prop-2-enoyl]phenyl}-benzenesulfonamide (CPN).

1 Negative control: 20 μL dimethylsulfoxide (DMSO). 2 Positive control: 0.5 μg 4-nitroquinoline 1-oxide (4-NQO)/plate for TA98 and 1.5 μg sodium azide/plate for TA100. All values are means ± SD of three independent experiments. 3 Statistical analysis: one-way ANOVA and the Tukey’s test. a, b, c, d Letter in common in the same column do not present significant difference (p > 0.05). Different letters in the same column present significant difference (p < 0.05). Means ± standard deviation (SD) of histidine revertant colonies, mutagenic index (MI), and inhibition percentage (IP) of mutagenicity for two tester strains of Salmonella typhimurium, TA98 and TA100, after treatment with different doses of sulfonamide chalcone N-{4-[3-(4-nitrophenyl)prop-2-enoyl]phenyl}-benzenesulfonamide (CPN).
