title: Genotoxicity of quinone pigments from pathogenic fungi.
abstract: The genotoxicity and mutagenicity of several kinds of quinone pigments from pathogenic fungi were examined by means of the hepatocyte primary culture (HPC)/DNA repair test and of Ames test with TA98 and TA100. Clear genotoxicity of the two quinone chemicals, xanthomegnin and luteosporin were observed in the HPC/DNA repair test, though definite mutagenicity was not detected in the Salmonella microsome test. These two pigments are thus suspected to be genotoxic carcinogens.
