  • Publication number: 20110002875
    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.

  • Patent number: 7786174
    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: 20090099100
    Abstract: Therapeutic compounds and methods for modulating amyloid aggregation in a subject, whatever its clinical setting, are described. Amyloid aggregation is modulated by the administration to a subject of an effective amount of a therapeutic compound of the formula or a pharmaceutically acceptable salt or ester, such that modulation of amyloid aggregation occurs. R1 and R2 are each independently a hydrogen atom or a substituted or unsubstituted aliphatic or aryl group. Z and Q are each independently a carbonyl (C?O), thiocarbonyl (C?S), sulfonyl (SO2), or sulfoxide (S?O) group. “k” and “m” are 0 or 1, provided when k is 1, R1 is not a hydrogen atom, and when m is 1, R2 is not a hydrogen atom. In an embodiment, at least one of k or m must equal 1. “p” and “s” are each independently positive integers selected such that the biodistribution of the therapeutic compound for an intended target site is not prevented while maintaining activity of the therapeutic compound.
