One of the pivotal mechanisms projected for bioflavonoids in cancer chemoprevention is through their intervention against mutagen-DNA interaction. Recent literatures emphasize the role of troxerutin (TXER) as an emerging anticancer agent. However, there are no reports on its intervention in any carcinogen-DNA interaction. The present study investigates the possibility of TXER, in prevention of 2-aminoanthracene (2-AA) contact with DNA. Steady state and time resolved fluorescence spectroscopy results, highlight the direct contact of 2-AA with DNA, while presence of TXER prevented this interaction...
