Inability of chlorophenols to induce 6-thioguanine-resistant mutants in V79 Chinese hamster cells.
The induction of mutation at the hypoxanthine-guanine phosphoribosyl transferase locus and cytotoxicities of 6 different chlorophenols (2,4- and 2,6-dichlorophenol, 2,4,5- and 2,4,6-trichlorophenol, 2,3,4,6-tetrachlorophenol and pentachlorophenol) were examined in V79 Chinese hamster cells without exogenous metabolic activation. The chlorophenols were cytotoxic to V79 cells, but failed to produce significant increases in the frequency of 6-thioguanine-resistant mutants.
