Applicant's summary and conclusion
- Conclusions:
- It is concluded that the substance shows evidence of mutagenic activity, possibly as a result of base-pair substitution, when tested in this bacterial system.
- Executive summary:
In the dose range finding test the substance was toxic towards the tester strains, especially in the absence of metabolic ctivation, at the higher dose levels. Therefore the top dose levels chosen for the subsequent mutation test were 500 microgr/plate, in the presence of metabolic activation, and 50 microgr/plate, in the absence of metabolic activation.
However, the toxic effect of the substance was less marked with strainWP2 uvrA than the other 5 strains, thus a top dose level of 1000 microgr/plate was chosen for WP2 uvrA in the presence of metabolic activation.
In both mutation tests, increases in revertant colony numbers were observed with tester starins TA 135 and TA 100, in the presence of metabolic activation, and with WP2 uvrA, in the presence and absence of etabolic activation, following treatment with EPICLON EXA-4032.
It is concluded that EPICLON EXA-4032 shows evidence of mutagenic activity, possibly as a result of base-pair substitution, when tested in this bacterial system.
