Abstract: | Fecapentaenes are potent mutagenic compounds found in human feces that are considered as potential colon carcinogens. It is demonstrated that a synthetic racemic all-trans fecapentaene-12 (fec-12) causes a strong dose-dependent increase in the frequency of sister-chromatid exchanges (SCE) in human lymphocytes exposed at different stages of the cell cycle. The SCE-inducing capacity is consistent with published results on the DNA-damaging activity of fec-12 such as formation of DNA single-strand breaks and interstrand cross-links. |
