Mutagenicity tests of 4-phenyl-1,3-dithia-2-thioxo-cyclopent-4-ene.

Abstract

The mutagenicity of 4-phenyl-1,3-dithia-2-thioxo-cyclopent-4-ene (DT827B) was examined in reverse mutation tests using Salmonella typhimurium and Escherichia coli, in the chromosomal aberration test with Chinese hamster ovary (CHO) cells, and in the micronucleus test using mice bone-marrow. In reverse mutation assay on DT827B according to Ames' method, DT827B was not mutagenic to S. typhimurium or E. coli when tested in dimethylsulfoxide to the limit of its solubility where precipitation occurred. In chromosomal aberration assay using CHO cells, DT827B was not clastogenic to induce structural chromosomal aberration but capable of inducing polyploidy. In micronucleus test, DT827B did not show micronucleus-inducing potential at the maximum dose. In conclusion of the three mutagenicity studies, DT827B was considered to cause no mutagenicity under the conditions used in the present experiments except the increase in polyploidy, which probably is due to a toxic effect of the compound.
