Glycogen Synthase Kinase-3β Inhibition of 6-(Methylsulfinyl)hexyl Isothiocyanate Derived from Wasabi (Wasabia japonica Matsum)

抄録

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.
