1,6-Dinitropyrene: mutagenicity in Salmonella and carcinogenicity in BALB/c mice.
In tests on the carcinogenicity of 1,6-dinitropyrene [(1,6-DNP) CAS: 42397-64-8] and 1-nitropyrene [(1-NP) CAS: 5522-43-0], 0.1 mg of each compound was inoculated sc into BALB/c mice once a week for 20 weeks. In the group given injections of 1,6-DNP the first tumor appeared on day 112, and 10 of the 20 mice developed tumors at the injection site by 45 weeks after the first injection. However, no tumors were induced in any of the mice that received injections of 1-NP. All of the induced tumors were transplantable for more than five generations in male BALB/c mice. Most of the tumors showed the characteristic histologic features of malignant fibrous histiocytoma.
