Intact glucosinolates are biologically inactive, whereas after the disruption of plant cells, they are hydrolysed by a β-thioglucosidase enzyme called myrosinase. Among the breakdown products, the isothiocyanates are associated to important protecting effects . In addition to the prevention of chronic disease, it is largely reported a strong correlation between the consumption of cruciferous vegetables and the decreased risk for different types of cancer. Indeed, it has been demonstrated that extracts of broccoli and watercress inhibit the invasive potential of human breast cancer cell lines in vitro . This effect may be explained by the ability of glucosinolates-hydrolysis products to regulate the phase I and/or phase II detoxification enzymes activity . Therefore, isothiocyanates could be considered as a new class of invasion inhibitors.
