  • Patent number: 7285293
    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.

  • Publication number: 20040259211
    Abstract: A method of induction of amyloid plaques includes immobilizing a quantity of a selected sulfated glycosaminoglycan (SGAG) on a selected medium and adding to the immobilized SGAG on the medium a quantity of dissolved low fibrillar A&bgr; 1-40 (LFA&bgr;). The LFA&bgr; is added preferably in a A&bgr;:SGAG w/w ratio of about 1:1. SGAGs are preferably selected from heparin, heparan sulfate, keratan sulfate, dermatan sulfate, chondroitin-4-sulfate and chondroitin-6-sulfate.

  • Publication number: 20040260076
    Abstract: Methods for the synthesis, isolation, and purification of procyanidin B2 are disclosed. The synthetic methods utilize epicatechin as a starting material and produce procyanidin B2 in high yields. The isolation methods extract procyanidin B2 from a sample of bark powder from plant matter of the genus Uncaria. The isolated and/or synthesized procyanidin B2 is used to treat amyloid disease, such as Alzheimer's disease and Parkinson's disease. Pharmaceutical compositions containing the synthesized and/or isolated procyanidin B2 are also disclosed.
