Glycogen synthase kinase-3β inhibition of 6-(methylsulfinyl)hexyl isothiocyanate derived from wasabi (Wasabia japonica Matsum)

Biosci Biotechnol Biochem. 2011;75(1):136-9. doi: 10.1271/bbb.100507. Epub 2011 Jan 7.


A new biological activity of 6-(methylsulfinyl)hexyl isothiocyanate derived from Wasabia japonica was discovered as an inhibitor of glycogen synthase kinase-3β. The most potent isothiocyanate, 9-(methylsulfinyl)hexyl isothiocyanate, inhibited glycogen synthase kinase-3β at a K(i) value of 10.5 µM and showed ATP competitive inhibition. The structure-activity relationship revealed an inhibitory potency of methylsulfinyl isothiocyanate dependent on the alkyl chain length and the sulfoxide, sulfone, and/or the isothiocyanate moiety.
