The invention pertains to novel compounds of the general formula (I): M - L in which M stands for a radioisotope of Tc or Re, L stands for a ligand of the general formula (II): B-CO-(CR1R2)n=1,2-S-CHR3-CHR4-SO2-NH-CR5R6-(CR7R8)m=1,2- SR9 in which R1, R2, R3, R4, R5, R6, R7, R8 and R9 can have different meanings, and B stands for another group which is suitable both for the dative bond of metal ions and for coupling with selectively concentrating compounds. That coupling can alternatively be effected on R8. These novel compounds serve to form complexes of technetium and rhenium and are used in medical diagnostics and therapy.
L'invention concerne de nouveaux composés de la formule générale (I): M - L dans laquelle M est un radioisotope de Tc ou Re, L désigne un ligand de la formule générale (II): B-CO-(CR?1¿R?2¿)¿n=1,2?-S-CHR?3¿-CHR?4¿-SO¿2?-NH-CR?5¿R?6¿-(CR?7¿R?8¿)¿m=1,2?-SR?9¿ dans laquelle R?1¿, R?2¿, R?3¿, R?4¿, R?5¿, R?6¿, R?7¿, R?8¿ et R?9¿ peuvent avoir différentes notations, et B désigne un autre groupe approprié pour la liaison dative d'ions métal et le couplage avec des composés à concentration sélective. Ce couplage peut également s'effectuer en variante sur R?8¿. Ces nouveaux composés servent à la complexation du technétium et du rhénium et ont des applications diagnostiques et thérapeutiques médicales.
