The uptake of alpha-aminoiso[3H]butyric acid and 32Pi was observed to be inhibited by sodium cyanate in transplanted hepatomas but was increased in the livers of the tumor bearing rats. Incorporation of 32Pi into macromolecules in hepatomas was also inhibited by cyanate. Treatment with this drug did not influence circulating concentrations of isotope-labeled materials. There were relatively small effects on uptake of 36Cl- in cyanate-treated rats and the action was not tissue specific. The data were compatible with an inhibitory effect of cyanate on active transport in hepatomas which was not seen under the same conditions in host liver.
