ADR-529 [(+)-1,2-bis(3,5-dioxopiperazin-1-yl)propane], a nonpolar, cyclic analogue of EDTA, protects against anthracycline cardiotoxicity in vivo. The protective mechanism presumably involves chelation of iron by a hydrolysis product of ADR-529, thus preventing the formation of reactive iron/oxygen species which can damage membrane

The factors that determine the field-dependent increase in 1/T1 of tissue water protons were investigated for MnCl2 and Mn2+ (PDTA) (1,3-propylenediamine-N,N',N'',N'''-tetraacetic acid) introduced intravenously into rabbits. Mn2+ was used in preference to other paramagnetic ions in part because of the

Since contrast in magnetic resonance imaging (MRI) is so sensitive to the magnetic relaxation rates of tissue protons, the use of paramagnetic ions to alter contrast in a tissue-specific fashion is an alluring prospect. The influence of these ions on
