The genotoxicity of 10 epoxides was investigated in the UDS test with primary rat hepatocytes. The sensitivity of the assay was demonstrated using 2-acetylaminofluorence. The epoxides 1,2-epoxyoctane, 1,2-epoxydecane, epoxycyclooctane, epoxycyclododecane, (+)-limoneoxide, alpha-pinaneoxide, transstilbeneoxide, and cis-2,3-epoxysuccinic acid, which are known to be non-mutagenic in the Ames test, as well as the bacterial mutagen, 1,2-epoxyphenoxypropane did not induce UDS in primary hepatocytes of the rat. However, a positive UDS response obtained with glycidyltrimethylammonium chloride showed that metabolic inactivation of the oxirane ring in hepatocytes is influenced by further structural substituents.
