title: Investigation of the possible involvement of ketonic derivatives of polycyclic hydrocarbons in hydrocarbon carcinogenesis.
abstract: 5,6-Dihydro-5-oxo-7,12-dimethylbenz(a)anthracene and 5,6-dihydro-6-oxo-7,12-dimethylbenz(a)anthracene are described. These compounds, which are isomeric with 7,12-dimethylbenz(a)anthracene-5,6-oxide (the K-region epoxide), were inactive in tests for tumor-initiating activity in mouse skin and tumor production in the s.c. tissue of the mouse.
