Opis:: The mutagenicity of two, newly synthesized amino-derivatives of cyclopenta[c]phenanthrene (CP[c]Ph) was investigated in the Ames test using TA98 and TA100 histidine dependent Salmonella typhimurium strains. Neither of the examined compounds showed mutagenic activity without metabolic activation. The incorporation of an activation system caused high mutagenicity of CP[c]Ph derivatives in both S. typhimurium strains. The results are compared with the previous data on the mutagenic activity of unsubstituted CP[c]Ph and possible mechanisms of activation are discussed.

Opis:: Polycyclic aromatic hydrocarbons (PAHs) are widely spread environmental pollutants mainly originating from anthropogenic sources such as fossil fuel combustion, industries, and others. Although a large body of literature exists on the toxicity and carcinogenicity of PAHs, primarily benzo[a]pyrene, toxicity data for phenanthrene deriveratives are very limited. The main aim of the experiment was to investigate if there exists correlation between molecular structure and mutagenic activity of four phenanthrene derivatives: 1 methylphenanthrene, 4 methylphenanthrene, 1 phenylphenanthrene, and 4 phenylphenanthrene. An Ames assay using two strains of histidine dependent Salmonella Typhimurium (TA98 and TA100) was conducted to assess the mutagenic activity of studied compounds both in the presence (+S9) and in the absence (-S9) of an exogenous source of metabolic activation. The compounds were also tested in an in vitro chromosome aberration assay in which V-79 cells were exposed to the phenanthrene derivatives investigated both in the presence and in the absence of metabolic activation. The phenylphenanthrenes showed no mutagenic effect. These compounds occasionally induced significant decrease in the number of revertants in the Ames test. The greatest mutagenic effects were observed for 1 methylphenanthrene after metabolic activation (+S9). In the micronucleus test the greatest mutagenic effect was observed for 4 methylphenanthrene also in the presence of metabolic activation system. The results obtained are comparable to those reported earlier for the methylphenanthrenes.
