A method for manufacturing a biocompatible fluid including a powder of magnetic particles of elongated shape having a magnetic shape anisotropy and having a final granulometry, the final granulometry being defined by a first average size of the particles in a first direction and a second average size in a second direction different from the first direction, the final granulometry further being defined by a first distribution width of the first sizes and a second distribution width of the second sizes, the method including from a powder of magnetic particles having an initial granulometry different from the final granulometry, modification of the initial granulometry by milling and/or by sintering of the powder until the final granulometry is obtained; introduction of the powder of magnetic particles into a biocompatible fluid.

Disclosed herein are complexes of gadolinium metal, ligand and meglumine that are substantially free of non-aqueous solvents. In particular, solvent-free complexes of 1) gadopentetate dimeglumine and 2) gadoterate meglumine are disclosed and methods of their preparation are disclosed. In addition, methods are disclosed for purifying reactants, monitoring and controlling pH, quantifying the free gadolinium content, quantifying the concentration of gadolinium-ligand complex in aqueous solution, and procedures for producing a drug product in one step. The one step process eliminates the need to dry the gadolinium-ligand complex, which is typically highly hygroscopic. The one step process includes purification steps that do not require the use of non-aqueous solvents.

Provided herein are magnetic resonance imaging (MRI) contrast agents comprising a compound having a structure represented by: YXZ, wherein, X is: Fe(III) or Mn(II), and Y and Z are each independently selected from pyrophosphate and bisphosphonate (e.g., 1-hydroxybisphosphonate), or a pharmaceutically acceptable hydrate and/or salt thereof. Methods of use of the MRI contrast agent are also provided.

The present disclosure relates to texaphyrin compounds linked with an antitumor antibiotic such as an anthcyanine antitumor antibiotic such as doxorubicin and danurubicin. The texaphyrin and the antitumor antibiotic are joined together by a group which is cleavable in vivo and results in increased activity and deliverance of the cytotoxic compound to target cells. Also provided herein are pharmaceutical compositions and methods of use thereof.

The present invention relates to compounds that are useful as metal ligands and which either contain a molecular recognition moiety or can be bound to a molecular recognition moiety and methods of making these compounds. Once the compounds that contain a molecular recognition moiety are coordinated with a suitable metallic radionuclide, the coordinated compounds are useful as radiopharmaceuticals in the areas of radiotherapy and diagnostic imaging. The invention therefore also relates to methods of diagnosis and therapy utilising the radiolabelled compounds of the invention.

The present invention relates to the use of non-equivalent mobile protons belonging to NMR distinguishable steroisomers of a CEST agent in a ratiometric based CEST imaging procedure and to Lanthanide (III) complex compounds displaying at least two NMR-distinguishable steroisomers in solution useful as concentration independent CEST responsive agents.

Described herein is a contrast agent for administration to a subject. The contrast agent includes a targeting portion that includes a hydrazide functional group; a metal ion bound to a metal-complexable portion; and a linker joining the targeting portion and the metal-complexable portion of the contrast agent. The portion that is not bound to a metal ion localizes the contrast agent to necrotic tissue in the subject.
