DETERMINATION OF CYTOTOXICITY
- Method: other: back groud lawn evaluation, number of spontaneous revertant colonies - Evaluation criteria:
- The assay is considered valid if the following criteria are met:
- the solvent control data are within the laboratory's normal control range for the spontaneous mutant frequency.
- the positive controls induced increases in the mutation frequency which were both statistically significant and within the laboratory's normal range.
A test compound is classified as mutagenic if it has either of the following effects:
a) it produces at least a 2-fold increase in the mean number of revertants per plate of at least one of the tester strains over the mean number of revertants per plate of the appropriate vehicle control at complete bacterial background lawn.
b) it induces a dose-related increase in the mean number of revertants per plate of at least one of the tester strains over the mean number of revertants per plate of the appropriate vehicle control in at least two to three concentrations of the test compound at complete bacterial background lawn.
If the test substance does not achieve either of the above criteria, it is considered to show no evidence of mutagenic activity in this system.
The test results must be reproducible.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
The test item is not mutagenic in bacterial test systems either with or without exogenous metabolic activation at the dose levels investigated. - Executive summary:
The test item was tested for mutagenicity with the strains TA 100, TA 1535, TA 1537 and TA 98 of Salmonella typhimurium.
Two independent mutagenicity studies were conducted, each in the absence and in the presence of a metabolizing system derived from a rat liver homogenate.
For all studies, the compound was suspended in DMSO, and each bacterial strain was exposed to 6 dose levels. Doses for all studies ranged from 4 to 5000 µg/plate.
Control plates without mutagen showed that the number of spontaneous revertant colonies was within the laboratory's historical control range. All the positive control compounds showed the expected increase in the number of revertant colonies.
Toxicity:
In the mutagenicity experiments toxicity was not observed either with or without metabolic activation.
A toxicity test using histidine-enriched agar plates and a dilution of the tester strain TA 1 00 (designated TA 1 00 D) was performed in parallel with the second experiment.
The test compound proved to be not toxic to the bacterial strain.
Mutagenicity:
In the absence and in the presence of the metabolic activation system the test item did not result in relevant increases in the number of revertants in any of the bacterial strains.
The test item is not mutagenic in these bacterial test systems either with or without exogenous metabolic activation at the dose levels investigated.
