  • Title: Mutagenic action of a series of epoxides.
    Author: Wade MJ, Moyer JW, Hine CH.
    Journal: Mutat Res; 1979 Apr; 66(4):367-71. PubMed ID: 379632.
    Abstract:
    The mutagenicity of a series of 13 epoxide compounds was studied using a bacterial plate assay system. The histidine-dependent tester strains TA98 (for frameshift mutagens) and TA100 (for base-pair substitution mutagens) of Salmonella typhimurium were used. Mutagenicity was evaluated both with and without the additon of rat liver microsomal extract. Dieldrin, diglycidyl ether of bis phenol A and 3 of its homologues were not mutagenic. Allyl glycidyl ether, n-butyl glycidyl ether, vinly cyclohexene diepoxide, glycidol, glycidal-dehyde, diglycidyl ether, diepoxybutane and diglycidyl ether of substituted glycerine were mutagenic in the TA100 strain, causing reversion of the bacteria to histidine independence. Dose-reponse curves of the mutagenicity of the latter 4 compounds were obtained. On a molar basis, glycidaldehyde was about 20-50 times more potent in producing mutation that were the other 3 epoxides in the dose-response test. In general, the mutagenicity of the epoxides was not enhanced or diminished by the addition of microsomal extract.
