Abstract:
Among flavonoids, chalcones have been identified as interesting compounds having antioxidant, antimutagenic and antitumour properties. In this study we have evaluated the clastogenicity of plicatin B on human lymphocytes (whole blood and isolated lymphocytes) and its anticlastogenic activity, in the same cellular systems, using mitomycin C (MMC), radio-mimetic bleomycin (BL) and hydrogen peroxide (H2O2) as reference clastogens. Plicatin B per se resulted cytotoxic at high dose but non-clastogenic. The clastogenic effects induced by MMC and BL were significantly reduced (-33%) whereas with H2O2 the protective effect of plicatin B was observed (-62%) only at the greater H2O2 dose. The anticlastogen effects of plicatin B were effective when the chalcone was introduced in the culture, 1 h before the reference clastogens.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
