According to the results of the present study, the test substance is not mutagenic in the Ames test under the experimental conditions chosen here. - Executive summary:
In a GLP compliant mutagenicity test, performed according to OECD guideline 471, 4 Salmonella typhimurium strains (TA 1535, TA 1537, TA 98, and TA 100) were used to test the mutagenic potential of the test substance both with and without metabolic activation. Two experiments were performed; a standard plate test and preincubation test, respectively. In both tests, bacteria were exposed to 0, 1562.5, 3125, 6250, 12500, 25000 µg/plate. No precipitation of the test substance was found and no bacteriotoxic effect was observed. An increased in the number of his+ revertants was not observed in the standard plate test or in the preincubation test either without S9 mix or after the addition of a metabolizing system. It was therefore concluded that the test substance is not mutagenic under these experimental conditions.
