Low relevanceCytotoxic, genotoxic and antigenotoxic potencies of oligorutins.
Trametes versicolor
Key points
- Rutin has been enzymatically oligomerized by laccase from Trametes versicolor
- Five fractions of oligomers were obtained from the monomers having high solubility in water, which can reach 351-times that of rutin
- Oligorutin fractions showed a lower antiproliferative effect compared with its monomer
- None of the tested concentrations of either rutin or oligorutin fractions has showed a genotoxic effect
- Similarly, the antigenotoxic effect of these flavonoids was tested using the same assay
- The obtained results showed a higher ability of oligorutin fractions to reduce the genotoxicity induced by hydrogen peroxide compared with monomeric rutin

Citation abstract
Rutin has been enzymatically oligomerized by laccase from Trametes versicolor. Five fractions of oligomers were obtained from the monomers having high solubility in water, which can reach 351-times that of rutin. Cytotoxicity of rutin and oligorutin fractions was evaluated towards K562 cells. Oligorutin fractions showed a lower antiproliferative effect compared with its monomer. The genotoxic potential of rutin and oligorutin fractions was assessed, at the limit of the solubility of each molecule, using the comet test. None of the tested concentrations of either rutin or oligorutin fractions has showed a genotoxic effect. Similarly, the antigenotoxic effect of these flavonoids was tested using the same assay. The obtained results showed a higher ability of oligorutin fractions to reduce the genotoxicity induced by hydrogen peroxide compared with monomeric rutin.
