摘要
Chelating compounds for labeling bioactive molecules with a radiometal, having general formula (I) in which: both Y groups may be positioned either trans as shown or cis; A is an effector molecule, such as a peptide, in particular octreotide, CCK, substance P, gastrine, a protein, in particular an antibody or enzyme, sugars or radiosensitizing agents, like doxorubicin; R is a hydrogen, a CSUB1/SUB-CSUB3 /SUBalkyl or a alcohol; X is a spacer, in particular (CHSUB2/SUB)SUBn/SUB-X', in which n is 1-10 and X' is COOH, NHSUB2/SUB, SH, OH or O-halogen, in which halogen is in particular Br, I or Cl, or a molecule of the formula (a) or of the formula (b), Y is COO-, CHSUB2/SUBCONHSUB2/SUB, CHSUB2/SUBCHSUB2/SUBOH, optionally complexed with a radiometal.
