INHIBITION OF BETA AMYLOID BINDING TO GLYCOSAMINOGLYCANS FOR TREATMENT OF ALZHEIMER'S DISEASE

摘要

The present invention relates to compounds that inhibit the binding of glycosaminoglycans and proteoglycans to beta amyloid peptide (A(beta); A beta ), and to compounds that inhibit A beta activation of complement. In one aspect, the compound is a peptide having an amino acid sequence X-X-N-X, in which X is an amino acid with a cationic side chain and N is a neutral amino acid. In another aspect, the compound is a peptide having an amino acid sequence X-X-N-X-Z, in which X is an amino acid with a cationic side chain, N is a neutral amino acid and Z is a neutral amino acid. In yet another aspect, the compound is peptide having an amino acid sequence X1-N-X2-X3, in which at least two of X1, X2, and X3 are independently an amino acid with an anionic side chain and the third X is an amino acid with an anionic side chain or a neutral amino acid and N is independently a neutral amino acid. In yet a further aspect, the compound is an anionic disaccharide. The invention also relates to a method for treating Alzheimer's disease comprising administering a therapeutically effective amount of a compound as described above to a subject suffering from Alzheimer's disease. Pharmaceutical compositions are also provided.
