The comparison of cytotoxic and genotoxic activities of glucosinolates, isothiocyanates, and indoles.

ABSTRACT: Chemopreventive properties of Brassica vegetables are attributed mainly to their characteristic compounds-glucosinolates (GLs) and their main hydrolysis products-isothiocyanates (ITCs) and indoles. In this study, we compared antiproliferative activity (MTT test in HT29 cells) and genotoxic effects (comet assay in HT29 cells and restriction analysis in a cell-free system) of three GLs (sinigrin (SIN), glucotropaeolin (GTL), and glucobrassicin (GLB)) with that of their major degradation products. Intact GLs did not exhibit cytotoxic activity, possibly due to their limited bioavailability. However, in the presence of myrosinase (MYR), GLs gained the ability to inhibit HT29 cells' growth. The addition of MYR caused the hydrolysis of GLs to the corresponding ITCs or indoles, i.e. compounds that
