title: New potential cytotoxic and antitumor substances. II. Effect of hydroxyanthraquinones and their glucosides on Ehrlich ascites carcinoma cells in vitro.
abstract: Mono and dihydroxyanthraquinones and their derivatives affected the utilization of 14C-labeled precursors nucleic acid and protein synthesis into Ehrlich ascites carcinoma (EAC) cells. Inhibitory effect of the substances markedly increased when one acetyl group was introduced into the basic molecule. As the tested substances inhibited mainly incorporation of 14C uridine into the cold TCA insoluble fraction of EAC cells, their mechanism of action can be explained by the inhibition of RNA synthesis.
