Description
6-Methylsulfinylhexyl isothiocyanate (6-MSITC) is an isothiocyanate that has been found in wasabi (
W. japonica) and has diverse biological activities. It inhibits nitric oxide (NO) production in mouse peritoneal exudate macrophages when used at a concentration of 5 μM. It inhibits aggregation of isolated human platelets induced by arachidonic acid (Item Nos.

10006607; IC
50 = 21.9 μM). 6-MSITC reduces cell survival in a panel of breast, brain, colon, lung, ovarian, renal, and prostate cancer cell lines (mean IC
50 = 43.7 μM).
In vivo, 6-MSITC (5 mg/kg twice weekly) reduces apoptosis of substantia nigral dopaminergic neurons and motor dysfunction in a mouse model of Parkinson''s disease induced by 6-OHDA . 6-MSITC also reduces the number of lung metastases in a B16/F10 murine melanoma model.
Uses
6-(Methylsulfinyl)hexyl isothiocyanate derived from Wasabia japonica was discovered as an inhibitor of glycogen synthase kinase-3β.
Definition
ChEBI: 1-isothiocyanato-6-(methylsulfinyl)hexane is a sulfoxide.
in vivo
Hesperin (6-Methylsulfinylhexyl isothiocyanate, 6-MSITC) activates Nrf2 and induces phase II enzyme genes but this induction is absent in Nrf2-null mice, suggesting that Hesperin is a potential activator of the Nrf2/ARE-dependent detoxification pathway. To determine whether Hesperin ameliorates hepatic steatosis and iron accumulation, wild-type and Nrf2-null mice are fed the following diets for 12 weeks: 1) control diet, 2) high-fat diet (HFD), 3) HFD plus Hesperin (10 mg/kg/day ip), 4) HFD for 6 weeks followed by an iron-supplemented HFD for 6 weeks (HFD/Iron), 5) HFD/Iron plus Hesperin. The HFD increased hepatic triglycerides in both genotypes and Hesperin suppress increased hepatic triglycerides in wild-type mice but do not reduce these
triglycerides in Nrf2-null mice[1].
