Evaluation of genotoxic potential of avarol, avarone, and its methoxy and methylamino derivatives in prokaryotic and eukaryotic test models.

| Abstract |
In this study, mutagenic and genotoxic potential of anti-tumor compounds avarol, avarone, and its derivatives 3'-methoxyavarone, 4'-(methylamino)avarone and 3'-(methylamino)avarone was evaluated and compared to cytostatics commonly used in chemotherapy (5-fluorouracil, etoposid, and cisplatin). Mutagenic potential of selected hydroquinone and quinones was assessed in prokaryotic model by the SOS/umuC assay in Salmonella typhimurium TA1535/pSK1002. Genotoxic potential was also assessed in eukaryotic models using comet assay in human fetal lung cell line (MRC-5), human adenocarcinoma epithelial cell line (A549), and in human peripheral blood cells (HPBC). The results indicated that avarol and avarone do not exert mutagenic/genotoxic potential. Among the studied avarone derivatives, mutagenic potential was detected by SOS/umuC test for 3'-(methylamino)avarone, but only after metabolic activation. The results of comet assay indicated that 3'-methoxyavarone and 3'-(methylamino)avarone have a significant impact on the level of DNA damage in the MRC-5 cell line. Genotoxic potential was not observed in A549 cells or HPBC probably due to a different uptake rate for the compounds and lower in metabolism rate within these cells.
