    摘要: 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 as well as improve cognitive performance and increase learning and memory in Alzheimer's patients. Pharmaceutical compositions containing the synthesized and/or isolated procyanidin B2 are also disclosed.

    摘要: 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 Aβ 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 Aβ fibrillogenesis. Related extraction methods are disclosed.

    摘要: A pharmaceutical composition that includes a peptide of formula Y-(X-aa)-Z. (X-aa) is generally an amino acid sequence selected from -Arg-Val-Ser-Val-Arg-Trp-, -Arg-Val-Ala-Val-Ile-, -His-Gly-Arg-Leu-Val-Phe-, -Leu-Ala-Phe-Val-Leu-Arg-, and -Thr-Leu-Phe-Leu-Ala-Arg-. And Y is generally an amino terminal modifying group selected from an amino acid, a N-acylated amino acid, a peptide, a N-acylated peptide, and hydrogen. And Z- is carboxyl-terminal modifying group selected from hydrogen, an amino acid, a C-amidated amino acid, a peptide, a C-amidated peptide, or an amide or hydroxyl group such as an alkyl amide, an aryl amide, or an alcohol. A composition of matter that includes at least one of the peptide sequences -Arg-Val-Ala-Val-Ile-, -Leu-Ala-Phe-Val-Leu-Arg-, -Thr-Leu-Phe-Leu-Ala-Arg-, -Arg-Val-Ser-Val-Arg-Trp-, -His-Gly-Arg-Leu-Val-Phe-. Preferably at least one amino acid of the peptide sequence is a D-amino acid.
