Abstract

The effects of several aromatic carcinogens and their noncarcinogenic analogs on the production of α β interferon by mouse embryo fibroblasts were determined. The carcinogens 2-naphthylamine and 9,10-dimethylanthracene significantly depressed α β interferon production, while their poorly or noncarcinogenic analogs, 1-naphthylamine and anthracene, respectively, had no significant effect. Neither the carcinogen benzidine nor its poorly carcinogenic analog 3,3′,5,5′-tetramethylbenzidine had any effect on α β interferon production. These data, taken together with previous findings, suggest the possibility of drawing a high correlation between the carcinogenic potential of a chemical and its effect on interferon production.
