  • Publication number: 20080004244
    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: 20070265334
    Abstract: Therapeutic compounds and methods for inhibiting amyloid deposition in a subject, whatever its clinical setting, are described. Amyloid deposition is inhibited by the administration to a subject of an effective amount of a therapeutic compound comprising an anionic group and a carrier molecule, or a pharmaceutically acceptable salt thereof, such that an interaction between an amyloidogenic protein and a basement membrane constituent is inhibited. Preferred anionic groups are sulfonates and sulfates. Preferred carrier molecules include carbohydrates, polymers, peptides, peptide derivatives, aliphatic groups, alicyclic groups, heterocyclic groups, aromatic groups and combinations thereof.
