Antiplatelet and anticancer isothiocyanates in Japanese domestic horseradish, wasabi.
6-Methylsulfinylhexyl isothiocyanate (MS-ITC) was isolated from wasabi (Wasabia japonica, Japanese domestic horseradish) as a potential inhibitor of human platelet aggregation in vitro through our extensive screening of vegetables and fruits. In the course of another screening for the induction of glutathione S-transferase (GST) activity in RL34 cells. MS-ITC was inadvertently isolated from wasabi as a potential inducer of GST. MS-ITC administered to rats or mice also showed both activities in vivo. As a result from elucidation of the platelet aggregation inhibition and the GST induction mechanisms of MS-ITC, the isothiocyanate moiety of MS-ITC plays an important role for antiplatelet and anticancer activities because of its highly reactivity with sulfhydryl (-SH) groups in biomolecules (GSH, cysteine residue in a certain protein, etc.).
