Disclosed is a prodrugs of the formula (I) where A is a sulfur or a selenium, and R is derived from a mono- di- or oligosaccharide. Also disclosed is a prodrug of the formulas (II); where A is sulfur or selenium, R' is derived from a sugar and R' has the formula (CHOH)nCH2OH, where n is 1 to 5, or R' is an alkyl or aryl group, or R' is =O, and the R'' groups may be the same or different and may be hydrogen, alkyl, alkoxy, carboxy. Also disclosed is a conjugate of an antioxidant vitamin and a thiolamine or selenolamine. Also disclosed is a prodrug of the formula (III); where A is sulfur or selenium, and R' is derived from a sugar and R' has the formula (CHOH)nCH2OH, where n is 1 to 5, or R' is also an alkyl or aryl group, or R' is =O, and R+ is an alkoxy, or an amine group. Also disclosed is a prodrug of the formula (IV) R is COOH or H, and R' is derived from a sugar and R' has the formula (CHOH)nCH2OH, where n is 1 to 5, or R' is an alkyl or aryl group, or R' is =O.
