The present invention discloses that imaging agents which comprise a specific type of matrix metalloproteinase inhibitors (MMPi's) of the sulphonamide hydroxamate class labelled with an imaging moiety, are useful diagnostic imaging agents for in vivo imaging and diagnosis of the mammalian body.
The present invention provides a novel imaging agent targeting the mannose-6-phosphate (M6P) receptor suitable for the non-invasive visualization of fibrosis. A method for the preparation of the imaging agent is also provided by the invention, as well as a precursor for use in said method. The invention also provides a pharmaceutical composition comprising the imaging agent and a kit for the preparation of the pharmaceutical composition. In a further aspect, use of the imaging agent for in vivo imaging and in the preparation of a medicament for the diagnosis of a condition in which the mannose-6-phosphate receptor is upregulated is provided.

show peripheral coordination resulting in polymeric crystal structures. The new NS3-aromatic cage ligand 18 binds Ag(I) peripherally giving a polymeric structure in the solid state and fluxional behaviour in solution. NMR evidence for equally populated central and peripheral coordination sites is coherent with results from DFT calculations.
