Cytotoxicity and mutagenicity of the fungicides captan and folpet in cultured mammalian cells (CHO/HGPRT system)

Abstract

The cytotoxicity and mutagenicity of the fungicides captan and folpet were determined in the CHO/HGPRT system which utilizes Chinese hamster ovary cells and resistance to 6-thioguanine to estimate mutation induction at the hypoxanthine-guanine phosphoribosyl transferase locus. Treatment of cultures with each compound for 5 hr is serum-free medium resulted in reproducible, significant, concentration-dependent increase in the frequency of 6-thioguanine-resistant mutants.
