  • Patent number: 6562836
    Abstract: Methods and compositions which are useful in the treatment of amyloidosis. In particular, methods and compositions are provided for inhibiting, preventing and treating amyloid deposition, e.g., in pancreatic islets, wherein the amyloidotic deposits are islet amyloid polypeptide (IAPP)-associated amyloid deposition or deposits. The methods of the invention involve administering to a subject a therapeutic compound which inhibits IAPP-associated amyloid deposits. Accordingly, the compositions and methods of the invention are useful for inhibiting IAPP-associated amyloidosis in disorders in which such amyloid deposition occurs, such as diabetes.

  • Publication number: 20030027796
    Abstract: Therapeutic compounds and methods for modulating amyloid deposition in a subject, whatever its clinical setting, are described. Amyloid deposition is modulated by the administration to a subject of an effective amount of a therapeutic compound comprising a phosphonate group and a carboxylate group, a congener thereof, or a pharmaceutically acceptable salt or ester thereof. In preferred embodiments, an interaction between an amyloidogenic protein and a basement membrane constituent is modulated.

  • Publication number: 20020115717
    Abstract: Amyloid-targeting imaging agents such as radiolabeled amyloid targeting molecules and amyloid targeting molecule-chelator conjugates for imaging, e.g., amyloid plaques in vivo, and/or for the treatment of amyloidosis disorders. The invention provides amyloid-targeting imaging agents that are useful for imaging sites of amyloid disease. Imaging agents of the invention are capable of binding specifically to amyloid plaques, as an aid in diagnosis and/or early treatment of amyloidosis disorders.
