Patent

CA 2382057

This invention relates to macrocyclic chelants comprised of one or two heteroatom-containing bridges, compositions containing them and their use in medicine, particularly in diagnostic imaging and radiotherapy. This invention relates especially to the use of metal chelates of the macrocyclic chelants as metallopharmaceuticals in Magnetic Resonance Imaging (MRI) and radiopharmaceuticals. This invention also relates to macrocyclic chelants as bifunctional chelating agents (BFC's) for the labeling of biologically active targeting molecules such as proteins, peptides, peptidomimetics, and non- peptide receptor ligands, with metal ions and radioisotopes.

L'invention concerne des chélateurs macrocycliques constitués de une ou de deux liaisons contenant des hétéroatomes, des compositions contenant ces chélateurs et leur application en médecine, plus particulièrement dans l'imagerie diagnostique et la radiothérapie. Cette invention concerne surtout l'utilisation de chélates métalliques de chélateurs macrocycliques comme métallopharmaceutiques dans l'imagerie par résonance magnétique (IRM) et les produits radiopharmaceutiques. Cette invention concerne également des chélateurs macrocycliques pouvant être utilisés comme agents chélateurs bifonctionnels pour le marquage de molécules de ciblage biologiquement actives telles que des protéines, des peptides, des peptidomimétiques, et des ligands du récepteur non peptidique, avec des ions métalliques et des radio-isotopes.
