- Observations:
Without S9-mix:
In tester strain TA1537, STI571 D6 induced up to 5.8-fold,
dose related, increase in the number of revertant colonies
compared to the solvent control in the first experiment and
up to 2.7-fold, not dose related, increase in the second
experiment.
In the other four tester strains (TA1535, TA98, TA100 and
WP2uvrA), STI571 D6 did not induce a dose-related, two-fold,
increase in the number of revertant colonies in two
independently repeated experiments.
With S9-mix:
In tester strain TA1537, STI571 D6 induced up to 6.5-fold,
dose related, increase in the number of revertant colonies
compared to the solvent control in the first experiment and
up to 3.7-fold, not dose related, increase in the second
experiment. In tester strain TA98, STI571 D6 induced up to
1.4- and 3.9-fold, dose related, increases in the number of
revertant colonies compared to the solvent control in the
first and second experiment, respectively. In tester strain
TA100, STI571 D6 induced up to 5.1- and 6.7-fold, dose
related, increases in the number of revertant colonies
compared to the solvent control in the first and second
experiment, respectively.
In the other two tester strains (TA1535 and WP2uvrA), STI571
D6 did not induce a dose-related, two-fold, increase in the
number of revertant colonies in two independently repeated
experiments.
Based on the results of this study it is concluded that
STI571 D6 is mutagenic in the Salmonella typhimurium reverse
mutation assay and STI571 D6 is not mutagenic in the
Escherichia coli reverse mutation assay. - Remarks on result:
