Methods for the production of monoclonal antibodies specific to conformational epitope(s) of a prefibrilar aggregate(s) which contribute to amyloid fibril formation in human or animal subjects who suffer from amyloid diseases (e.g. Alzheimer's Disease) and the hybridomas and monoclonal antibodies produced therefrom. Also, the use of such monoclonal antibodies in the immunization of human or animal subjects against Alzheimer's Disease or other amyloid diseases and/or for the diagnosis or detection of Alzheimer's Disease or other amyloid diseases. The monoclonal antibodies may be administered concomitantly or in combination with anti-inflammatory agents, such as gold or gold containing compounds, to decrease neural inflammation associated with amyloid diseases (e.g. Alzheimer's Disease).

The present invention relates to pharmaceutical compositions and methods for the prevention and treatment of autoimmune diseases, infectious diseases, neurodegenerative diseases, and primary and metastatic neoplastic diseases. In the practice of the invention, the compositions are employed comprising: (a) a heat shock protein (hsp) or an alpha(2)macroglobulin (alpha2M); (b) a saponin; and, optionally, (c) an antigenic molecule. The antigenic molecule displays the antigenicity of an antigen of: (a) a cell that elicits an autoimmune response; (b) an agent of an infectious disease; (c) a cancerous cell; or (d) a cell or structure associated with a neurodegenerative or amyloid disease. The hsps that can be used in the practice of the invention include but are not limited to hsp70, hsp90, gp96, calreticulin, hsp 110, grp 170, and PDI, alone or in combination with each other. The antigenic molecule can be covalently or noncovalently bound to the hsp or alpha2M, free in solution, and/or covalently bound to the saponin. The compositions of the invention can be administered alone or in combination with the administration of antigen presenting cells sensitized with an hsp- or alpha2M-antigenic molecule complex.

The present invention is directed to pharmaceutical agents and compositions useful for the treatment and prevention of amyloid disease in a subject. The invention further relates to isolated antibodies that recognize a common conformational epitope of amyloidogenic proteins or peptides that are useful for the diagnosis, treatment, and prevention of amyloid disease.

The invention provides methods and kits for detecting conformationally altered proteins and prions in a sample. In one embodiment, the conformationally altered proteins and prions are associated with amyloidogenic diseases.

Transthyretin (TTR), a tetrameric thyroxine (T4) carrier protein, is associated with a variety of amyloid diseases. Derivative of biphenyl ethers (BPE), which are shown to interact with a high affinity to its T4 binding site thereby preventing its aggregation and fibrillogenesis. They prevent fibrillogenesis by stabilizing the tetrameric ground state of transthyretin. Two compounds (2-(5-mercapto-[1,3,4]oxadiazol-2-yl)-phenol and 2,3,6-trichloro-N-(4H-[1,2,4]triazol-3-yl) exhibit the ability to arrest TTR amyloidosis. The dissociation constants for the binding of BPEs and compound 11 and 12 to TTR correlate with their efficacies of inhibiting amyloidosis. They also have the ability to inhibit the elongation of intermediate fibrils as well as show nearly complete (>90%) disruption of the preformed fibrils. Biphenyl ethers and compounds 11 and 12 as very potent inhibitors of TTR fibrillization and inducible cytotoxicity.

Amyloid-targeting imaging agents such as radiolabeled amyloid targeting molecules and amyloid targeting molecule-chelator conjugates for imaging, e.g., amyloid plaques in vivo, and/or for the treatment of amyloidosis disorders. The invention provides amyloid-targeting imaging agents that are useful for imaging sites of amyloid disease. Imaging agents of the invention are capable of binding specifically to amyloid plaques, as an aid in diagnosis and/or early treatment of amyloidosis disorders.

The present invention provides pharmaceutical compositions comprising quinazolinecarboxamide derivative, and certain novel quinazolinecarboxamide derivatives capable of inhibiting heparan sulfate-glycosaminoglycan (HS-GAGs) interactions with L-selectin, and useful in the prevention or treatment of various diseases, disorders and conditions mediated by HS-GAGs, particularly inflammatory and autoimmune diseases, viral diseases, cancer, and amyloid disorders.

The inventors investigated to provide a means for real-time detection and measurement on the process of the amyloid protein aggregation as change(s) in tension and/or elasticity using a force sensor. The present invention provided a method of detecting an amyloidgenic conformational change of a protein using a mechanochemical sensor. The present invention further provided a method of searching a substance having an activity that affects to an amyloidgenic conformational change using said detecting method, as well as a method of searching a therapeutic or diagnostic agent for amyloid-related diseases. The method of the present invention is assumed to contribute to obtain a novel therapeutic or diagnostic agent for amyloid diseases.

The present invention is directed to compounds that inhibit amyloid aggregation and methods of treatment there-with.

The present invention relates to antibodies and antibody fragments specific for the toxic prefibrillar aggregates of amyloid-beta peptides, and uses thereof, for example in the diagnosis and treatment of amyloid diseases such as Alzheimer's disease and related disorders. The invention further provides methods for the identification of compounds potentially useful for the treatment of an amyloid disease, such as Alzheimer's disease.

A method of treating an amyloid disease, or a disease characterized by alpha-synuclein or NAC fibrillogenesis, in a mammalian subject.
