- with and without
- Metabolic activation system:
- Rat liver S9-mix induced by a combination of phenobarbitone and ß-naphthoflavone
- Test concentrations with justification for top dose:
- - Preliminary test:
TA100 and WP2uvrA:
Without and with S9-mix: 0.15, 0.5, 1.5, 5, 15, 50, 150, 500, 1500 and 5000 µg/plate
- Experiment 1:
TA 1535, TA 1537, TA 98 and TA 100:
Without and with S9-mix: 5, 15, 50, 150, 500, 1500 and 5000 µg/plate
E. coli WP2 uvr A:
Without and with S9-mix: 50, 150, 500, 1500 and 5000 µg/plate

TA 1535, TA 1537, TA 98 and TA 100:
Without and with S9-mix: 15, 50, 150, 500, 1500 and 5000 µg/plate
E. coli WP2 uvr A:
Without and with S9-mix: 50, 150, 500, 1500 and 5000 µg/plate - Vehicle / solvent:
- - Vehicle: acetone
- Justification for choice of vehicle: the test material was immiscible in DMSO at 50 mg/mL but was fully miscible in acetone at the same concentration. Sterile distilled water was not selected following information supplied by the sponsor. Acetone was therefore selected.

- yes
- Negative solvent / vehicle controls:
- yes
- Positive controls:
- yes
- Positive control substance:
- other: see section "Any other information on materials and methods incl. tables"

- METHOD OF APPLICATION: in agar (plate incorporation)
DURATION
- Exposure duration: 48 hour
NUMBER OF REPLICATIONS:
- Preliminary test: 1
- Experiment 1 and 2: 3
DETERMINATION OF CYTOTOXICITY
- Method: The reduction of the bacterial background lawn and the reduction of the revertant colonies.
OTHER EXAMINATIONS:
- The presence of precipitation of the test compound on the plates was determined. - Evaluation criteria:
- There are several criteria for determining a positive result, such as a dose-releated increase in revertant frequency over the dose range tested and/or a reproducible increase at one or more concentrations in at least one strain with or without metabolic activation. Biological relevance of the results will be considered first, statistical methods, as recommended by the UKEMS can also be used as an aid to evalaution, however, statistical significance will not be the only determining factor for a positive respons.
A test material will be considered non-mutagenic (negative) in the test system if the above criteria are not met.
Although most experiments will give clear positive or negative results, in some instances the data generated will prohibit a definitive judgement about the test material activity. Results of this type will be reported as equivocal. - Statistics:

RANGE-FINDING/SCREENING STUDIES:
- In tester strain TA100, toxicity was observed at dose levels of 1500 μg/plate and above in the absence and presence of S9-mix. In tester strain WP2uvrA, no toxicity or mutagenicity was observed up to and including the top dose of 5000 µg/plate
COMPARISON WITH HISTORICAL CONTROL DATA:
- The negative and strain-specific positive control values were within the laboratory historical control data ranges indicating that the test conditions were adequate and that the metabolic activation system functioned properly.
ADDITIONAL INFORMATION ON CYTOTOXICITY:
TA 1535, TA 1537, TA 98 and TA 100: toxicity was observed at dose levels of 1500 μg/plate and above
WP2uvrA: No toxicity or mutagenicity was observed up to and including the top dose of 5000 µg/plate
Applicant's summary and conclusion
- Conclusions:
- The mutagenic activity of the substance was evaluated in accordance with OECD 471 (1997) and according to GLP principles. Based on the results of this study it is concluded that the substance is not mutagenic in the Salmonella typhimurium reverse mutation assay and in the Escherichia coli reverse mutation assay with and without metabolic activation.
- Executive summary:
The mutagenic activity of the substance was evaluated in accordance with OECD 471 (1997) and according to GLP principles. The test was performed in two independent experiments, both in the absence and presence of S9-mix. The substance was tested up to limit concentrations. Adequate negative, solvent and positive controls were included. The substance did not induce a significant dose-related increase in the number of revertant (His+) colonies in each of the four S. typhimurium tester strains (TA1535, TA1537, TA98 and TA100) and in the number of revertant (Trp+) colonies in tester strain WP2uvrA, both in the absence and presence of S9-metabolic activation. These results were confirmed in independently repeated experiments. Based on the results of this study it is concluded that the substance is not mutagenic in the Salmonella typhimurium reverse mutation assay and in the Escherichia coli reverse mutation assay with and without metabolic activation.
