6-Selenoguanosine (NSC 137679) was stablized and formulated as a lyophilized parenteral paroduct using ascorbic acid as an antioxidant. In addition to preventing the oxidation of 6-selenoguanosine to the corresponding diselenide in aqueous solution, ascorbic acid reduced the diselenide already in the bulk drug. Dithioerythritol and sodium bisulfite also were evaluated as antioxidants. Dithioerythritol
