Abstract: A method of treating an amyloid disease in a patient or inhibiting the formation, deposition, accumulation, or persistence, of amyloid fibrils, amylin fibrils, or islet amyloid fibrils, and/or dissolving or disrupting pre-formed or pre-deposited amyloid fibrils in type II diabetes in a mammalian subject. In the method a therapeutically effective amount of plant matter form the genus Uncaria, species Tomentosa is administered, preferably from the inner bark or root tissue of Uncaria Tomentosa.
Abstract: Substituted n-aryl benzamides, related compounds and their pharmaceutically acceptable derivatives, their synthesis, pharmaceutical compositions containing them, and their use in the treatment of amyloid diseases, including A? amyloidosis, such as observed in Alzheimer's disease, IAPP amyloidosis, such as observed in type 2 diabetes, and synucleinopathies, such as observed in Parkinson's disease, and the manufacture of medicaments for such treatment are provided.

Abstract: A screening assay for selecting macromolecules that interfere with the binding of a sulfated GAG to beta amyloid, the assay comprising affixing a sulfated GAG to a substrate, co-incubating the macromolecule and a known amount of beta amyloid with the sulfated GAG, determining the amount of beta amyloid bound to the sulfated GAG affixed to the substrate; wherein the macromolecule will be one which interferes with the binding of the sulfated GAG to beta amyloid.
Abstract: Bis- and tris-dihydroxyaryl compounds and their methylenedioxy analogs and pharmaceutically acceptable esters, pharmaceutical compositions containing them, and their use in the treatment of amyloid diseases, especially A? amyloidosis, such as observed in Alzheimer's disease, use in the reduction of A? peptide in vivo, use in modulating APP processing, and use in modulating the activity of APP secretase.

Abstract: A method for inhibiting the formation or persistence of brain amyloid deposits in a patient, including administering to the patient a therapeutically effective amount of plant matter from a plant of the genus Hypericum, species perforatum.
Abstract: Assay-guided affinity fractionation and reverse phase high pressure liquid chromatography (HPLC) methodology to isolate, test and characterize the most active water-soluble ingredients within Cat's Claw, or Uncaria tomentos. These components appear to account for the majority of the amyloid or A? fibrillogenesis inhibitory activity. Individual fractions and/or compounds as isolated by HPLC are tested in relevant in vitro and/or animal models, and found to consistently demonstrate inhibition of amyloid or A? fibrillogenesis. Related extraction methods are disclosed.
