title: Pulmonary adenoma response of strain A mice to sulfonic acid derivatives of 1- and 2-naphthylamines.
abstract: Various sulfonic acid derivatives of 1-naphthylamine and 2-naphthylamine were tested in inbred A/St (male and female) mice by the pulmonary adenoma bioassay to determine if this class of compounds, used as intermediates in the dye-stuff industry, possesses tumorigenic activity. Neither 1-naphthylamine nor the four sulfonic acid derivatives of 1-naphthylamine tested were tumorigenic. However, 2-naphthylamine and two of the three sulfonic acid derivatives of 2-naphthylamine tested produced statistically significant lung tumor responses at comparable doses. These results indicated that this class of compounds should be examined more extensively for carcinogenic activity.
