Abstract

See full text

Chelating compounds of specified N.sub.2 S.sub.2 N.sub.3 S derived structure are useful for radiolabeling targeting molecules such as antibodies. Cleavable ester orthioester linkers connect the radionuclide metal chelates to the antibodies. The radiolabeled antibodies have improved biodistribution properties, including reduced localization within the intestines and kidneys.
