title: Carcinogenicity in mice of mutagenic compounds from a tryptophan pyrolyzate.
abstract: The compounds 3-amino-1,4-dimethyl-5H-pyrido[4,3-b]indole and 3-amino-1-methyl-5H-pyrido[4,3-b]indole, which are potent mutagens in a tryptophan pyrolyzate, ar hepatic carcinogens when given orally to mice at concentrations of 200 parts per million in a pellet diet. Female mice showed higher susceptibilities to both compounds than male mice.
