What do isothiocyanates do?

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.

How are isothiocyanates formed?

1.1 Isothiocyanates Isothiocyanates can be formed by the reaction of an aromatic amine with thiophosgene (Rifai and Wong, 1986). The group reacts with nucleophiles such as amines, sulfhydryls, and the phenolate ion of tyrosine side chains (Podhradsky et al., 1979).

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 antioxidants?

Antioxidant activity Many isothiocyanates, particularly sulforaphane, have been shown to induce the expression of antioxidant enzymes via the activation of the nuclear factor E2-related factor 2 (Nrf2)-dependent pathway (9, 10).

What does sulforaphane do for the body?

Phytochemicals like sulforaphane are antioxidants that cancel out free radicals. Free radical are tiny particles that weaken and damage healthy cells. They form in your body because of pollution, UV rays, food additives and preservatives, and even through natural processes like digestion. It reduces inflammation.

Are isothiocyanates toxic?

Isothiocyanate is toxic to the gastrointestinal tract as indicated by the clinical signs of fluid to hemorrhagic diarrhea that can be severe. Within 3 to 4 hours, domestic and wild herbivores that received moderate to high doses of glucosinolate developed anorexia and colic.

Does sulforaphane reduce inflammation?

Because sulforaphane neutralizes toxins, it also calms inflammation in your body. Inflammation has been linked to several kinds of cancer. It may protect your DNA. Some studies have shown that sulforaphane blocks mutations in DNA that lead to cancer.

Can you have too much sulforaphane?

High doses of sulforaphane produced marked sedation (at 150–300 mg/kg), hypothermia (at 150–300 mg/kg), impairment of motor coordination (at 200–300 mg/kg), decrease in skeletal muscle strength (at 250–300 mg/kg), and deaths (at 200–300 mg/kg).
