The invention relates to amphiphilic derivatives of a triazamacrocyclic compound, as well as to said derivatives as active molecule transporters. The invention also relates to a nanodrug including at least one amphiphilic derivative of a triazamacrocyclic compound and at least one active molecule of a protein such as an antibody, in particular for the treatment of autoimmune diseases or for the treatment of cancer.

Provided are macrocyclic compounds and compounds with two or more macrocyclic groups, iron coordinated macrocyclic compounds, and iron coordinated compounds with two or more macrocyclic groups. The iron is high-spin iron(III). The iron coordinated compounds may exhibit a negative redox potential (e.g., relative to a normal hydrogen electrode at a biologically relevant pH, for example, a pH of 6.5-7.5). The compounds can be used as MRI contrast agents.

The present invention relates to a method for detecting renal disease and for assessing the efficacy of dialysis treatment using imaging agents having desirable in vivo properties.

The present application discloses compositions and methods of synthesis and use of .sup.18F- or .sup.19F-labeled molecules of use in PET, SPECT and/or MR imaging. Preferably, the .sup.18F or .sup.19F is conjugated to a targeting molecule by formation of a complex with a group IIIA metal and binding of the complex to a bifunctional chelating agent, which may then be directly or indirectly attached to the targeting molecule. In other embodiments, the .sup.18F or .sup.19F labeled moiety may comprise a targetable construct used in combination with a bispecific antibody to target a disease-associated antigen. The disclosed methods and compositions allow the simple and reproducible labeling of molecules at very high efficiency and specific activity in 30 minutes or less. In preferred embodiments, the bifunctional chelating agent bound to .sup.18F- or .sup.19F-metal complex may be conjugated to the molecule to be labeled at a reduced temperature, e.g. room temperature.
