These are phytochemicals which can increase activity of enzymes that help to detoxify carcinogens and are found in the cruciferous family of vegetables — broccoli, cauliflower, brussels sprouts, cabbage, turnips, and others.
Dithiolthiones and isothiocyanates are two classes of sulfur-containing compounds that are known for their potential health benefits and various biological activities. Here's some information about each of them:
Dithiolthiones:
Dithiolthiones, also known as dithiocarbamates, are organic compounds that contain two thiol (-SH) groups. One well-known dithiolthione is called dimethylthiocarbamate (DMTC). Dithiolthiones are commonly found as natural products in cruciferous vegetables like broccoli, cauliflower, and Brussels sprouts.
Dithiolthiones have been studied for their chemoprotective properties. They are known to induce the expression of enzymes involved in detoxification and antioxidant defense systems, such as glutathione S-transferases (GSTs) and NAD(P)H:quinone oxidoreductase 1 (NQO1). These enzymes play important roles in the metabolism and elimination of potentially harmful substances in the body.
Isothiocyanates:
Isothiocyanates are a class of compounds that contain the functional group -N=C=S. They are derived from their precursor molecules, glucosinolates, which are found in cruciferous vegetables as well. When the plant tissues are damaged, an enzyme called myrosinase converts glucosinolates into isothiocyanates through a process known as hydrolysis.
Some well-known isothiocyanates include sulforaphane, found in broccoli and broccoli sprouts, and phenethyl isothiocyanate, found in watercress and other cruciferous vegetables. Isothiocyanates have attracted considerable attention for their potential chemopreventive properties. They have been shown to exhibit anti-inflammatory, antioxidant, and anticancer effects in various preclinical and clinical studies.
Isothiocyanates are known to modulate several cellular processes involved in cancer development, including cell cycle arrest, apoptosis (programmed cell death), and inhibition of tumor angiogenesis (the formation of new blood vessels to support tumor growth).
It's worth noting that both dithiolthiones and isothiocyanates are subject to ongoing research, and their mechanisms of action and specific health benefits are still being investigated. However, consuming a diet rich in cruciferous vegetables, which naturally contain these compounds, is generally considered beneficial for overall health due to their nutrient content and potential protective effects against chronic diseases.
As always, it's important to consult with healthcare professionals or registered dietitians for personalized advice regarding your specific health concerns and dietary needs.
