The dose-response rat hepatic cytosolic receptor-binding avidities, aryl hydrocarbon hydroxylase (AHH) and ethoxyresorufin O-deethylase (EROD) induction potencies in rat hepatoma H-4-II E cells in culture were determined for 29 polynuclear aromatic hydrocarbons. It was apparent that the magnitude of the EC50 values for these in vitro responses were strongly dependent on structure. Dibenz[a,h]anthracene (1.6 X 10(-8) M), 7-methylbenz[a]anthracene (1.6 X 10(-8) M), 3-methylcholanthrene (2.8 X 10(-8) M) and picene (4.5 X 10(-8) m) exhibited the highest affinity for the receptor protein and these compounds were only 5-fold less active the 2,3,7,8-tetrachlorodibenzo-p-dioxin (1 X 10(-8) M). All of the compounds which were active in the receptor-binding and monooxygenase enzyme-induction assays possessed one common structural feature, namely the presence of a phenanthrene structure fused with at least 1 benzo ring. The results also demonstrated that there was not any apparent correlation between the receptor-binding avidities and in vitro monooxygenase enzyme-induction potencies for the most active polynuclear aromatic hydrocarbons.
