Novel method for down-regulation of amyloid

Disclosed are novel methods for combatting diseases characterized by deposition of amyloid. The methods generally rely on immunization against amyloid precursor protien (APP) or beta amyloid (Abeta). Immunization is preferably effected by administration of analogues of autologous APP or Abeta, said analogues being capable of inducing antibody production against the autologous amyloidogenic polypeptides. Especially preferred as an immunogen is autologous Abeta which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes. Also disclosed are nucleic acid vaccination against APP or Abeta and vaccination using live vaccines as well as methods and means useful for the vaccination. Such methods and means include methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations.

Prevention of brain inflammation as a result of induced autoimmune response

A disease characterized by amyloid aggregation in a patient may be prevented or treated by causing antibodies against a peptide component of the amyloid deposit to come into contact with the aggregated or soluble amyloid. In order to decrease the risk of inflammation in such a method, the Fc receptors of the patient are blocked, preferably by administration of an effective amount of IVIg, prior to the procedure of causing the antibodies to come into contact with the amyloid.

2-arylbenzothiophene derivatives or pharceutically acceptable salts thereof, preparation method thereof, and pharceutical composition for the diagnosis or treatment of degenerative brain disease containing the same as active ingredient

2-arylbenzothiophene derivatives or pharmaceutically acceptable salts thereof, a preparation method thereof, and a pharmaceutical composition for the diagnosis or treatment of degenerative brain disease containing the same as an active ingredient. Since the 2-arylbenzothiophene derivatives of Formula 1 have a relatively high binding affinity for β-amyloid, they can be used as diagnostic reagents for diagnosing Alzheimer's disease at an early stage by non-invasive techniques when they are labeled with radioisotopes:wherein R1-R4, V, W, X, Y and Z are as defined in the Detailed Descript of the specification. Further, when the pharmaceutical composition containing the 2-arylbenzothiophene derivative binds with a low-molecular weight β-amyloid peptide binding compound, generation of malignant high-molecular weight β-amyloid deposits is minimized. Accordingly, the pharmaceutical composition can be used as a therapeutic agent of degenerative brain disease such as Alzheimer's disease.
