What is isothiocyanate used for?
Isothiocyanates are naturally occurring small molecules that are formed from glucosinolate precursors of cruciferous vegetables. Many isothiocyanates, both natural and synthetic, display anticarcinogenic activity because they reduce activation of carcinogens and increase their detoxification.
Is sulforaphane a isothiocyanate?
Sulforaphane is an isothiocyanate occurring in stored form as glucoraphanin in cruciferous vegetables such as cabbage, cauliflower, and kale, and at high levels in broccoli especially in broccoli sprouts.
How do isothiocyanates prevent cancer?
Allyl isothiocyanate, a constituent of cruciferous vegetables, inhibits proliferation of human prostate cancer cells by causing G2/M arrest and inducing apoptosis.
What foods contain Peitc?
Although water cress and broccoli are known to be the richest source, PEITC can also be obtained from turnips and radish. PEITC is present as gluconasturtiin in cruciferous plants.
Are isothiocyanates harmful?
No serious adverse effects of isothiocyanates in humans have been reported. The majority of animal studies have found that isothiocyanates inhibited the development of cancer when given prior to the chemical carcinogen (pre-initiation).

Numerous studies have shown that polyphenols, including curcumin, quercetin, and resveratrol, exhibit multiple health benefits, including anti-inflammatory properties. Curcumin is a flavonoid polyphenol that is the active ingredient in the spice turmeric.
Are isothiocyanate dietary supplements effective?
Isothiocyanate dietary supplements present a potentially beneficial strategy to introduce key nutritional components to people, particularly with regard to addressing issues related to poor bioavailability/absorption of cooked cruciferous vegetables. However, some serious challenges persist and need to be urgently dealt with before moving forward.
What is the mechanism of action of isothiocyanates?
The mechanisms by which isothiocyanates exert their anti-carcinogenic effects are being investigated by many groups, and point to key mechanisms including induction of carcinogen detoxication and elimination through elevated NRF2 signaling [35] [36], enhanced DNA damage repair [37] [38], elimination of cancer stem cells [39] and others [40].
Does 2-Phenethyl isothiocyanate detoxify volatile organic carcinogens in smoke?
2-phenethyl isothiocyanate, glutathione S-transferase M1 and T1 polymorphisms, and detoxification of volatile organic carcinogens and toxicants in tobacco smoke. Cancer Prev Res (Phila)2016;9:598–606.
Does isothiocyanates interact with other medications or foods?
There is no information on whether isothiocyanates can interact with prescriptions or over the counter medications. However, its interaction with the CYP450 enzymes could lead to potential interaction with the enzyme’s substrates.
