Biochem/physiol Actions

BTA-1 is a probe for β-amyloid aggregates; fluorescent thioflavin-T derivative; exhibits high affinity for amyloid deposits; displays 50-fold higher affinity than thioflavin-T; selectively stains cerebral plaques and cerebrovascular amyloid deposits in the brains of PS1/APP transgenic mice, as well as Aβ fibrils in postmortem brain tissue obtained from AD patients; crosses the blood brain barrier.

In vivo assessment of the beta-sheet proteins deposited in amyloid plaques (A beta peptide) or neurofibrillary tangles (tau protein) presents a target for the development of biological markers for Alzheimer's disease (AD). In an effort to develop in vivo beta-sheet

Fibrillary tau aggregates in Alzheimer disease and allied neurodegenerative disorders have been visualized in vivo by PET, whereas mechanistic links between PET-detectable tau deposits and neurotoxicity remain elusive. Here, we took advantage of transgenic mouse models of tauopathies to evaluate

Intrinsic optical emissions, such as autofluorescence and second harmonic generation (SHG), are potentially useful for functional fluorescence imaging and biomedical disease diagnosis for neurodegenerative diseases such as Alzheimer's disease (AD). Here, using multiphoton and SHG microscopy, we identified sources of

The synthesis of a new lipophilic thioflavin-T analogue (2-[4' -(methylamino)phenyl]benzothiazole, 6) with high affinity for amyloid is reported. Intravenous injection of [(11)C]-labeled 6 in control mice resulted in high brain uptake. Amyloid deposits were imaged with multiphoton microscopy in the

2-(4'-methylaminophenyl)benzothiazole (BTA-1) is an uncharged derivative of thioflavin-T that has high affinity for Abeta fibrils and shows very good brain entry and clearance. In this study, we asked whether BTA-1, at concentrations typical of those achieved during positron emission tomography
