The bio-antimutagenic potential of benzaldehyde and its derivatives was investigated on mutagenesis induced by 4-nitroquinoline 1-oxide (4NQO) in Escherichia coli WP2s uvrA trpE. Benzaldehyde and 18 kinds of hydroxy-, methoxy-, or ethoxybenzaldehydes other than 3, 4-diethoxybenzaldehyde decreased the induced mutation frequency by 42 to 91%. Among these compounds, strong bio-antimutagenic effects were observed for vanillin (3-methoxy-4-hydroxybenzaldehyde), vanillal (3-ethoxy-4-hydroxybenzaldehyde), protocatechualdehyde (3, 4-dihydroxybenzaldehyde), 2, 5-dimethoxybenzaldehyde, o-anisaldehyde (o-methoxybenzaldehyde), and m-anisaldehyde. On the other hand, benzyl alcohol or benzoic acid analogues such as vanillyl alcohol, vanillic acid, isovanillic acid, and veratric acid did not show any bio-antimutagenic effects. These observations suggest that the aldehyde radical is important for bio-antimutagenic activity.
