Notes:
: Sakuranetin (compound 1) from bark of Prunus jamasakura showed a suppressive effect on umu gene expression of SOS response in Salmonella typhimurium TA1535/pSK1002 against the mutagen furylfuramide. Gene expression was suppressed 83% at a concentration of 0.70 μmol/mL. The ID50 value of compound 1 was 0.30 μmol/mL. This compound showed the suppression of 4NQO, MNNG, Trp-P-1, AfB1, activated Trp-P-1, and UV irradiation-induced SOS response. The methylated derivative (compound 2) of compound 1 showed less suppressive effect against all mutagens than compound 1. The antimutagenic activities of compounds 1 and 2 against furylfuramide, Trp-P-1, and activated Trp-P-1 were assayed by the Ames test using the S. typhimurium TA100 strain.
