Antigenotoxicity, antioxidant, chemoprotective agents, <i>diascoria pentaphylla, drosophila melanogaster</i>, methyl methanesulfonate


Objectives: Plants as dietary sources are known to have several chemoprotective agents. Dioscorea pentaphylla is an important medicinal plant, which is often used as edible food. This study was undertaken to evaluate the antigenotoxic potential of D. pentaphylla extracts on the genotoxic effect induced by methyl methanesulfonate (MMS) in the Drosophila wing spot test. Materials and Methods: The somatic mutation and recombination test (SMART) was carried out in Drosophila melanogaster. In transheterogyous larvae, multiple wing hair (mwh 3"‘0.3) and flare (flr3"‘38.8) genes were used as markers of the extent of mutagenicity. Results: It was observed thatall the three extracts (petroleum ether, choloroform, and ethyl alcohol) in the combined treatment had significantly inhibited the effect of MMS"‘induced genotoxic effects. When compared to others, the ethanol extract showed a very significant antimutagenic activity. Conclusion: The compounds that are present in the extracts may directly interact with the methyl radical groups of MMS and inactivate them by chemical reaction. It is also possible that the compounds in the extract compete to interact with the nucleophilic sites in deoxyribonucleic acid (DNA), thus altering the binding of the mutagen to these sites. Although our results indicate that the compounds present in the extracts may directly interact with the methyl radical groups of MMS and inactivate them by chemical reaction, it may also be quite interesting to investigate through the other different mechanisms by which D. pentaphyllacould interfere in vivo on the effect of genotoxic agents.
