Rhead, W. J. published the artcileSelenium catalyzed reduction of methylene blue by thiols, COA of Formula: C18H15N3O3, the publication is Bioinorganic Chemistry (1974), 3(3), 225-42, database is CAplus and MEDLINE.
The reduction of methylene blue [61-73-4], of other reducible dyes, as well as of riboflavine [83-88-5], hemin [16009-13-5], and of vitamin B12a [13422-51-0] by thiols was catalyzed by ¦ÌM amounts of Se. The reduction of methylene blue was investigated in greater detail and exhibited a complicated dependence on the pH and the thiol concentration Alkylating agents, CN-, as well as Cd+2 or Hg+2 were inhibitory, whereas Cu2+ or Ag+ had stimulatory effects. Dithiols were more effective reducing agents than monothiols. The catalytic effects of Se in these reactions may parallel some of the functions of Se in vivo.
