Abstract
The present invention relates particularly to novel pyridine based nitrogen-sulfur ligands that are suitable for complexing with a radionuclide, and are useful as general imaging agents for diagnostic purposes, novel aminothiol ligands that are suitable for complexing with a radionuclide, and are useful as general imaging agents for diagnostic purposes, and amide-thiolate ligands having improved metal chelate formation kinetics. The amide-thiolate ligands include an amine which converts to a vinylogous amide upon complexation, thereby providing rapid complexation and thermodynamic stability. The ligands may be used for post formed labeling of biological substances for use in the fields of diagnosis and therapy.
