On the reduction of dithiolethiones and dithiolylium ions by NADPH and glutathione reductase.

Results of in vitro experiments carried out in water at 25 degrees C and at pH 7.56 proved that NADPH in the presence of yeast glutathione reductase did not react with 1,2-dithiole-3-thiones and 1,2-dithiole-3-ones. On the other hand, 3-methylthiodithiolylium ions did react in these conditions.
