Effects of cyanate, thiocyanate, and amygdalin on metabolite uptake in normal and neoplastic tissues of the rat

J Natl Cancer Inst. 1979 Nov;63(5):1279-83.


Thiocyanate was found to resemble cyanate in its inhibitory effects on [3H]thymidine incorporation and the uptake of [32P]phosphate and [3H]amino acids in transplanted tumors of the BUF rat. The capacity to inhibit metabolite uptake in hepatomas and a colon tumor under conditions in which uptake was unchanged or increased in host liver was concluded to be a common feature of the action of cyanate and thiocyanate. Inhibition of [32P]phosphate uptake and [3H]thymidine incorporation into DNA of tumors was also observed after treatment of rats with amygdalin. With this drug, however, the action on tumors and livers of host rats was similar.
