METAL CHELATING COMPOUNDS

摘要

Ligands for radiopharmaceutical use are capable of chelating radiometal species and of being bound to biological targeting molecules. The ligands have formula (a) and (b), where A, A' = -SZ or Y, B = O or S, Y = (c), Z = H or a thiol protecting group, m = 2 or 3, n = 2 or 3, q = 0 or 1, R = H or unsubstituted or substituted hydrocarbon and pharmaceutically acceptable salts, provided that at least one CR2 group represents CO and forms, together with an adjacent N atom, a -CONR- amide group.
