ABSTRACT
The C2-alkylated acrolein derivatives 2-methylacrolein, 2-ethylacrolein and 2-propylacrolein are mutagenic in Salmonella typhimurium TA100. They are direct mutagens, their mutagenic potency being inversely proportional to the size of the alkylating substituent in the C2 position. In the presence of S9 mix, the mutagenicity of all these substances is considerably reduced; the reduction in mutagenicity is inversely proportional to the direct mutagenic potential of the substance. As shown for 2-methylacrolein, the reduction in mutagenicity is dependent on the concentration of S9 in the S9 mix and is not significantly influenced by heat inactivation of the S9 mix or by addition of TCPO, an inhibitor of epoxide hydrolase, to the testing system. There are no indications of enzymatic activation by the metabolizing microsomal system.
