The invention relates to chelate compounds which can be used in MRI, the chelates being intended to be conveyed by lipophilic transporters, such as lipid nanoparticles or liposomes. The invention also relates to compounds comprising, in association, these chelates and these transporters, if appropriate connected via chemical bonding groups, and to their use in diagnostic imaging, it being possible for this association additionally to comprise biological targeting markers, denoted biovectors.

A multifunctional cross-bridged tetraaza macrocyclic compound has at least one side arm that comprises a moiety that is capable of forming a bond with another molecule, which has a targeting moiety that directs the compound to a site a marker substance. The compound is chelated to a medically active material that generates a signal for diagnostic imaging or produces a therapeutic effect at the site of the marker substance. A method for detecting, diagnosing, and/or treating a disease that produces the marker substance uses a conjugate comprising the multifunctional cross-bridged tetraaza macrocyclic compound.

A convenient synthesis of a bifunctional derivative of the ligand NOTA is described. The synthesis offers advantages over current literature methods for making similar molecules by starting with the easily prepared ortho-amide of 1,4,7-triazacyclanonane which can be sequentially alkylated to provide a bifunctional NOTA derivative in 9% yield overall. The replacement of preparative HPLC with simple
