    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.

    摘要: 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 Aβ 1-40 (LFAβ). The LFAβ is added preferably in a Aβ: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. Screening methods and kits for screening either immobilize a quantity of a selected sulfated glycosaminoglycan (SGAG) on a selected medium, followed by adding to a quantity of dissolved low fibrillar Aβ 1-40 (LFAβ) a selected quantity of the selected amyloid therapeutic candidate to create a test solution, and then adding to the immobilized SGAG on the medium a selected quantity of the test solution to test for inhibition, or preform amyloid plaques on the medium by immobilizing a quantity of a selected sulfated glycosaminoglycan (SGAG) or a GAG-related macromolecule on a selected medium and then adding a selected quantity of dissolved low fibrillar Aβ 1-40 (LFAβ), followed by adding to the amyloid plaques on the medium a selected quantity of a test solution of a selected amyloid therapeutic candidate to test for disruption.
