Nrf2 is a basic leucine zipper transcriptional activator essential for the coordinated transcriptional induction of phase-2 and antioxidant enzymes. Brassica vegetables contain phytochemicals including glucoraphanin, the precursor of sulforaphane (SFN) and glucobrassicin, the precursor of
Compounds like indole-3-carbinol (I3C) have been shown to increase catechol estrogen formation and reduce mammary tumor incidence in mice. These compounds may exert a protective effect for breast cancer development by decreasing the overall estrogen pool available for the formation of 16
Searches for the natural compounds that determine the anticarcinogenic properties of a cruciferous-vegetable diet, revealed the products of alkaloid glucobrassicin biotransformations; among these, ascorbigen, an indole-containing derivative of L-ascorbic acid, was found to be the most abundant.
Broccoli is a popular brassica vegetable and its consumption may decrease the occurrence of cancer in certain populations. To gain insight into the metabolites that may induce physiological responses to broccoli intake, a non-targeted metabolomic approach and a targeted approach for analysis of
Consumption of cruciferous vegetables has been associated with a low risk of developing cancer. Indole-type phytonutrients, derived from enzymatic hydrolysis of glucobrassicin, exhibit cancer-preventive properties and occur in all vegetables of the Brassicaceae family. A LC-Q-TOF-MS methodology was
The chemical background of the biological activities of vegetables of the Cruciferae family is considered. These vegetables contain alkaloids of the glucobrassicin group that are decomposed by the enzyme myrosinase (thioglucosidase, EC 3.2.3.1) released upon damage to the plant cells. This results
Ascorbigens are indole-containing derivatives of L-ascorbic acid, some of them (e.g., 1'-methylascorbigen) have been shown to inhibit growth of experimental murine tumors. Immunomodulating properties of 1'-methylascorbigen correlated with its antitumor effect. The immunomodulating action of
Consumption of Brassica vegetables is associated with a reduced risk of cancer of the alimentary tract in animal models and human populations. We used raw juice extracted from Brussels sprouts rich in the glucosinolate sinigrin to explore the effect of naturally occurring glucosinolate breakdown
This review provides a historical perspective for the development of indole-3-carbinol (I-3-C) as a chemopreventive or therapeutic agent. Early experiments in animal models clearly showed that feeding cruciferous vegetables reduced the incidence of chemical carcinogenesis. Excitement was generated
The natural indoles 3,3'-diindolylmethane (DIM), ascorbigen (ASG), indole-3-carbinol (I3C), and indolo[3,2-b]carbazole (ICZ), as well as the natural isothiocyanates sulforaphane (SUL), benzyl isothiocyanate (BITC) and phenethyl isothiocyanate (PEITC), all possess cancer chemopreventive properties.
Formaldehyde (HCHO) may reach living organisms as an exogenous agent or produced within cells. The so-called formaldehydogenic compounds like S-adenosyl-L-methionine, N-hydroxymethyl-L-arginine, 1'-methyl ascorbigen, methanol, E-N-trimethyl lysine and methylamine are special exogenous sources of
