- Details on test system and experimental conditions:
- Design
The test article was evaluated in the initial mutagenicity assay at doses of 1.60, 5.00, 16.0, 50.0, 160, 500, 1600, and 5000 µg/plate, with and without S9. Positive and vehicle controls were evaluated concurrently. All test and control articles were evaluated in duplicate plates. An independent confirmatory assay subsequently was performed at doses of 50.0, 160, 500, 1600, and 5000 µg/plate, with and without S9. Positive and vehicle controls were evaluated concurrently, and all test and control articles were evaluated in triplicate plates.
Frequency and Route of Administration
Tester strains were exposed to the test article via the plate incorporation methodology originally described by Ames et al. (1975) and Maron and Ames (1983). This methodology has been shown to detect a wide range of classes of chemical mutagens. In the plate incorporation methodology, the tester strain, test article, and S9 mix (where appropriate) are combined in molten top agar, which is then overlaid onto a minimal bottom agar plate. Following incubation, revertant colonies are counted. - Evaluation criteria:
- A test article is considered to have produced a positive response if it induces a dose dependent increase in revertant frequency that is above 2.0-fold vehicle control values for tester strains TA98, TA100, and WP2uvrA, or above 3.0-fold vehicle control values for tester strains TA1535 and TA1537. In addition, any response should be reproducible.
A test article is considered to have produced a negative response if no dose-dependent, >2.0-fold or >3.0-fold increases are observed in tester strains TA98, TA100, and WP2uvrA, or TA1535 and TA1537, respectively.
Criteria for an Equivocal Response
Even after repeated trials, a test article may produce results that are neither clearly positive nor clearly negative (e.g., responses that do not meet the dose-dependency or fold increase requirements, but are reproducible). In those rare instances, the test article may be considered to have produced an equivocal response. - Statistics:
- The average revertants/plate and the standard deviation were calculated.

- Interpretation of results (migrated information):
negative
These results indicate the test substance was negative in the Bacterial Reverse Mutation Assay with a Confirmatory Assay under the conditions, and according to the criteria, of the test protocol. - Executive summary:
The objective of this study was to evaluate the test article, and/or its metabolites, for their ability to induce reverse mutations at the histidine locus in several strains of Salmonella typhimurium (Salmonella; TA98, TA100, TA1535, and TA1537), and at the tryptophan locus of Escherichia coli (E. coli) strain WP2uvrA in the presence or absence of an exogenous mammalian metabolic activation system (S9).
The substance was evaluated in the initial mutagenicity assay, in all five tester strains, at doses of 1.60, 5.00, 16.0, 50.0, 160, 500, 1600, and 5000 µg/plate with and without S9. All doses of the test article as well as the concurrent positive and vehicle controls were evaluated in duplicate plates. Normal growth was observed in all five tester strains at all doses evaluated with and without S9. In addition, the test article was found to be freely soluble in the aqueous top agar at all doses evaluated with and without S9. Revertant frequencies for all doses of test substance, in all tester strains with and without S9, approximated or were less than those observed in the concurrent vehicle control cultures.
The substance was re-evaluated in the confirmatory mutagenicity assay at doses of 50.0, 160, 500, 1600, and 5000 µg/plate with and without S9. All doses of the test article, as well as the concurrent positive and vehicle controls, were evaluated in triplicate plates. Normal growth again was observed in all five tester strains at all doses evaluated with and without S9. In addition, the test article again was found to be freely soluble in the aqueous top agar at all doses evaluated with and without S9. Revertant frequencies for all doses of test substance, in all tester strains with and without S9, again approximated or were less than control values.
All positive and vehicle control values were within acceptable ranges, and all criteria for a valid study were met.
These results indicate the test substance was negative in the Bacterial Reverse Mutation Assay with a Confirmatory Assay under the conditions, and according to the criteria, of the test protocol.
