چکیده

Isothiocyanates comprise the most promising class of chemopreventive phytochemicals. They are encountered at substantial amounts in cruciferous vegetables where they exist in the form of glucosinolates. Epidemiological studies have linked consumption of isothiocyanates to low cancer incidence at a number of sites. Furthermore, laboratory studies in animal models of cancer have established that various isothiocyanates can effectively antagonise the carcinogenicity of chemicals. A principal mechanism of action of these chemicals is to modulate the metabolism of chemical carcinogens so as to favour their metabolic detoxification. In this mini review we discuss the ability of isothiocyanates to influence carcinogen-metabolising enzyme systems, such as cytochromes P450 and conjugation systems, at dietary levels of exposure.

Nutraceutical Antioxidants as Novel Neuroprotective Agents

A variety of antioxidant compounds derived from natural products (nutraceuticals) have demonstrated neuroprotective activity in either in vitro or in vivo models of neuronal cell death or neurodegeneration, respectively. These natural antioxidants fall into several distinct groups based on their chemical structures: (1) flavonoid polyphenols like epigallocatechin 3-gallate (EGCG) from green tea...

Isothiocyanates: a review

Isothiocyanates (ITCs) are naturally occurring molecules belonging to highly reactive organosulphur synthons, with the general structure R–N=C=S. The precursor molecule glucosinolate anions are hydrolyzed enzymatically (under the effect of myrosinase enzymes) or unenzymatically to produce nitriles or isothiocyanates depending upon conditions such as pH and temperature. Brassicaceae  Family is k...
