Lead Compounds for Diagnosis and Therapy of Alzheimer's Disease

详细技术说明

UC San Diego researchers have identified several classes of molecules with excellent potential as lead compounds for therapeutic and imaging agents. Their proprietary approach has identified molecules that cannot be identified using historic methods. These compounds include non-dye classes of therapeutics and diagnostics for Alzheimer's disease and may provide alternatives to radiolabeled PET imaging agents and molecules under clinical development. By obviating the need for specific fluorescent, spectroscopic, radioactive, and mechanistic properties, this approach is yielding classes of compounds more compatible with and readily translatable to clinical practice. Specifically, many of these proprietary compounds have: Low molecular weight. Known and favorable pharmacokinetic properties. Known permeability across the blood-brain barrier. Ready commercial availability. FDA approval as drugs. Finally, while this approach has been developed using beta-amyloid fibrils found in Alzheimer's disease, the same high-throughput screen may be adapted to identify therapeutic/diagnostic agents for other neurologic diseases, including Parkinson's, Huntington, Down's Syndrome, bovine spongiform encephalopathy (mad cow disease), Kuru, Creutzfeldt-Jakob disease, and fatal familial insomnia.

*Abstract

A number of neurologic diseases, including Alzheimer's (AD), Huntington's, and Parkinson, are characterized by deposition of beta-amyloid plaques. These beta sheet-rich structures are formed from misfolded peptides or proteins that non-covalently self-aggregate to form oligomers, fibrils, and larger structures. The aggregation of beta-amyloid and other cellular proteins has been associated with beta-amyloid induced neurotoxicity in the pathogenesis of AD. Current therapeutic strategies are focused mainly on:

• Slowing down the production of beta-amyloid peptide.
• Preventing the growth of beta-amyloid fibrils.
• Disrupting the fibrils so that they disassemble into their beta-amyloid peptide components.

An alternative strategy of coating the substrate fibrils with "neutralizing" small molecules may prevent or alleviate the symptoms of neuronal diseases associated with amyloid fibril or plaque formation.

Title: Compounds and methods for the diagnosis and treatment of amyloid associated diseases
Usefulness: Compounds and methods for the diagnosis and treatment of amyloid associated diseases
Summary: For diagnosing, preventing or alleviating the symptoms of an amyloid associated disease e.g. neuronal disease such as Alzheimer's disease, Parkinson's disease, Huntington's disease, Down's Syndrome, and spongiform encephalopathy (claimed). For screening for a compound that blocks the binding of an A-β fibril binding molecule to A-β fibrils, screening for a compound used for diagnostic imaging of A-β-fibrils; diagnosing an amyloid associated disease in an individual, identifying a change in the progress of an amyloid associated disease in an individual and detecting amyloid deposits in an individual e.g. mammal such as human (all claimed). For diagnosing imaging of A-β fibrils and for studying normal or disease-associated cellular mechanism relating to amyloid proteins. The research reagent are used to detect the presence of an amyloid-associated disease or to assist in screening for compounds that may prevent or alleviate the symptoms of the disease, for inhibition of the interaction of an amyloid protein with a second binding protein to enable the study of a cellular or disease mechanism.
Novelty: New phenylbenzothiazoles useful for diagnosing and treating or preventing an amyloid associated disease e.g. Alzheimer's disease, Parkinson's disease, Huntington's disease
