Evidence for thiol-dependent production of oxygen radicals by 4-methyl-5-pyrazinyl-3H-1,2-dithiole-3-thione (oltipraz) and 3H-1,2-dithiole-3-thione: possible relevance to the anticarcinogenic properties of 1,2-dithiole-3-thiones.
1,2-Dithiole-3-thiones are an important class of anticarcinogens that selectively induce cellular production of chemoprotective phase II detoxification enzymes. It is important to identify chemical properties of anticarcinogens that are responsible for this enzyme induction. Previously, the ability of 1,2-dithiole-3-thiones to induce phase II enzymes has been attributed to their electrophilic c...
متن کاملA rapid and convenient synthesis of 5-unsubstituted 3,4-dihydropyrimidin- 2-ones and thiones
A rapid and convenient synthesis of 5-unsubstituted 3,4-dihydropyrimidin-2-ones and thiones was developed. The reaction involves a one-pot reaction between oxalacetic acid, thiourea/urea, and aldehyde under microwave irradiation and provides the products in good yields and much shorter reaction times. 2010 Elsevier Ltd.

متن کاملInactivation of protein tyrosine phosphatases by oltipraz and other cancer chemopreventive 1,2-dithiole-3-thiones.
Dithiolethiones upregulate the expression of cancer-preventive proteins via modification of thiol residues in the Keap1-Nrf2 transcription factor complex. In addition to Keap1-Nrf2, dithiolethiones have the potential to modify a variety of cysteine-containing proteins in the cell. Such 'off target' reactions could contribute to either side effects or cancer-preventive efficacy. Evidence is pres...
متن کاملSolvent-Free Multicomponent Reactions of Dithiocarbamates, Activated Acetylenes and Isocyanides
An efficient method to synthesis the 2H-pyrans using three component reactions of dithiocarbamats, activated acetylenes and isocyanides in water as the solvent is described. In these reactions, synthesis of 2H-pyrans is possible based on the one-pot reaction and without using any catalyst. The mild reaction conditions and high yields of the products exhibit synthetic advantage of these methods.
