The present invention relates to compounds and compositions useful as antioxidants and in particular to selenium containing compounds of formula (I): wherein n is 1, 2, or 3; m is 2, 3, 4, or 5; and each R] is independently -(optionally substituted C 1 -C3 alkylene) p-OH, where p is 0 or 1, or a salt thereof. The invention also relates to the use of these seleno-compounds in the treatment of diseases or conditions associated with increased levels of oxidants produced by myeloperoxidase (MPO), such as for instance, atherosclerosis.
Disclosed is the trisaccharide .alpha.-D-Glcp-(1-2)-.alpha.-D-Glcp-(1-3)-.alpha.-D-Glcp and compounds related thereto as well as pharmaceutical compositions thereof.
Hydantoins of formula (I) ##STR1## ps have biological properties related to those of naturally occurring prostaglandins and may be used in medicine, for example in the treatment of thrombosis.
The kinetics of the redox reactions of the peroxomonosulfate ion (HSO5−) with iron(II), vanadium(IV), cerium(III), chloride, bromide, and iodide ions were studied. Cerium(III) is only oxidized upon illumination by UV light and cerium(IV) is produced in a photoreaction with a quantum yield of 0.33 ± 0.03. Iron(II) and vanadium(IV) are most probably oxidized through one-electron transfer producing sulfate
