  • Patent number: 7754250
    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.

  • Patent number: 7723057
    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.

  • Patent number: 6929808
    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.
