Ligands for radiopharmaceutical use are capable of chelating radiometal species and of being bound to biological targeting molecules. The ligands have the 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 CR.sub.2 group represents CO and forms, together with an adjacent N atom; a --CONR-- amide group. ##STR1##
用于放射性药物的配体能够螯合放射性金属物种并与生物靶向分子结合。这些配体的化学式为(a)和(b),其中A,A'=--SZ或Y,B=O或S,Y=(c),Z=H或硫醇保护基,m=2或3,n=2或3,q=0或1,R=H或未取代或取代的碳氢化合物和药用盐,前提是至少一个CR.sub.2基团代表CO并且与相邻的N原子一起形成一个--CONR--酰胺基团。
