title: Inhibition of mutagenicity of food-derived heterocyclic amines by sulphoraphene--an isothiocyanate isolated from radish.
abstract: The naturally derived isothiocyanate, sulphoraphene [4-isothiocyanato-(1R)-(methylsulphinyl)-1-(E)-butene], isolated from seeds of radish ( Raphanus sativus L., Cruciferae) was investigated for its antigenotoxic effects against a battery of cooked food mutagens (heterocyclic amines) in the Ames Salmonella/reversion assay using Salmonella typhimurium TA98 (frame-shift mutation sensitive) and TA100 (base -pair mutation sensitive) bacterial strains in the presence of Aroclor 1254 induced rat liver S9. Results of the present in vitro anti-mutagenicity studies using the base-pair mutation sensitive strain TA100, strongly suggest that sulphoraphene is a potent inhibitor of the S9-mediated mutagenicity of all the tested heterocyclic amines (60 - 75 % inhibition at a dose of 500 nmol/plate).
