Abstract: A two-stage method of preparing essentially pure amino acid chelates, wherein the first stage comprises contacting a metal ion from a metal oxide or hydroxide with an amino acid thereby producing a metal hydroxyl amino acetate. The second stage comprises contacting the metal hydroxyl amino acetate from the first stage, with at least one amino-containing compound provided in excess thereby producing a reaction solution containing an amino acid chelate reaction product comprising a metal ion bound to a plurality of amino acid ligands wherein the plurality of amino acid ligands is equal to the coordination number of the metal ion, and then separating the amino acid chelate from the reaction solution. The second stage may include a plurality of steps for sequentially reacting the reaction product with a plurality of amino-containing compounds. The amino acid chelates thus produced can be incorporated into compositions comprising beverages, foodstuffs, nutraceuticals and pharmaceutical adjuvants.

Abstract: This invention provides novel cyclooxygenase-2 selective agents that are particularly useful as imaging probes in non-invasive imaging techniques, such as PET and SPECT. Preferred cyclooxygenase-2 selective agents inhibit cyclooxygenase-2 activity with greater potency and specificity than conventional cyclooxygenase-2 inhibitors. Other aspects of the invention include pharmaceutical compositions including the cyclooxygenase-2 selective agents as well as methods for detecting and/or inhibiting cyclooxygenase-2. These methods are particularly useful for diagnosing and treating disorders, such as inflammation, which is characterized by elevated cyclooxygenase-2 levels.

Abstract: Radioisotope generators comprising inorganic layered hydroxide composition, such as magnesium aluminates and lithium aluminates. These inorganic layered hydroxides form anion exchange materials that exhibit surprisingly high selective affinities for certain radioisotopes. Inorganic layered hydroxides have been prepared and shown to have high affinity for tungstate anions, the anion form of tungsten-188, yet low affinity for perrhenate anions, the anion form of rhenium-188.
Abstract: The invention includes methods and compounds for labelling conjugates with metals which comprise the steps of coupling the conjugate to a support surface; introducing a complex-forming metal to the support; and collecting the metal-conjugate complex released from the support. The metal catalyzes cleavage of the conjugate from the support upon complex formation resulting in a solutions substantially free of unlabeled conjugate.

Abstract: The present invention relates to compounds and related technetium and rhenium complexes thereof which are suitable for imaging or therapeutic treatment of tumors, e.g., carcinomas, melanomas and other tumors. In another embodiment, the invention relates to methods of imaging tumors using radiolabeled metal complexes. Preferred radiolabeled complexes for imaging tumors include technetium and rhenium complexes. The high tumor uptake and significant tumor/nontumor ratios of the technetium complexes of the invention indicate that such small technetium-99m-based molecular probes can be developed as in-vivo diagnostic agents for melanoma and its metastases. In yet another embodiment, the invention relates to methods of treatment of tumors using a radiolabeled metal complex as a radiopharmaceutical agent to treat the tumor.
