Abstract:

The antimutagenicity of α-hexylcinnamaldehyde (1), a semisynthetic and more stable derivative of cinnamaldehyde, was evaluated against common environmental pollutants in the bacterial reverse mutation assay. The pre-, co-, and post-treatment protocols were applied to assess the involvement of desmutagenic and/or bioantimutagenic mechanisms. Compound 1 (9-900 μM) produced a strong antimutagenicity (>40% inhibition) in the Salmonella typhimurium TA98 strain against the nitroarenes 2-nitrofluorene and 1-nitropyrene in almost all experimental conditions. A strong inhibition was also reached against the nitroarene 1,8-dinitropyrene and the arylamine 2-aminoanthracene in the cotreatment at the highest concentrations tested. In order to evaluate if an inhibition of bacterial nitroreductase (NR) and O-acetyltransferase (OAT) could be involved in the antimutagenicity of 1 against nitroarenes, the substance was further tested against 1-nitropyrene (activated by both NR and OAT) in TA98NR and TA98 1,8-DNP strains (lacking the NR and OAT enzymes, respectively). Although both desmutagenic and bioantimutagenic mechanisms appear mostly involved in the antimutagenicity of 1, based on data obtained in the TA98NR strain, applying the pretreatment protocol, compound 1 seems to act as an inhibitor of the OAT-mediated mutagen bioactivation. These results provide justification for further studies on 1 as a possible chemopreventive agent.
