An anthraquinone with genotoxic and carcinogenic activities
1-Hydroxyanthraquinone is an anthraquinone that has been found in Morinda officinalis and has genotoxic and carcinogenic activities.1,2 1-Hydroxyanthraquinone (5 and 500 µM) increases the percentage of isolated rat hepatocytes undergoing unscheduled DNA synthesis, indicating genotoxic activity.1 Dietary administration of 1-hydroxyanthraquinone (1%) induces formation of cecum and colon adenocarcinomas, as well as hepatocellular carcinomas, in rats.
