Beta-Amyloid and Neurofibriallary Tangle Imaging Agents
The invention provides the following: (1) A new biochemical (FBM) that can be used for research studies; (2) A precursor molecule that can be radiolabeled; (3) An imaging agent that can be used for PET diagnostic imaging of various neurodegenerative disorders including Alzheimer's disease, minimal cognitive impairment, dementia, inflammation associated with these neurological processes, inflammation as a result of other injuries or pathophysiologies related to cancer.
In order to reduce the lipophilicity of FDDNP, researchers at the University of California have designed a new analog. Researchers have radiolabeled the new analog, designated 'FBM', and performed in vitro studies in mice. These studies indicate that FBM is less lipophilic than FDDNP, while still having structural similarities to FDDNP. Also, FBM is able to provide higher target to non-target ratios than FDDNP in the transgenic mice hippocampus. The Tg2576 and triple transgenic mice brains have been shown to be a good model for Alzheimer's disease, because of the similar accumulation of beta-amyloid plaques. Therefore, the success of FBM showing specific binding to amyloid plaques in transgenic mice hippocampus shows potential as a new radiotracer. FBM also showed specific binding in the frontal cortex of the transgenic mice brain. Further evaluation of FBM in other brain regions and in vitro binding affinity studies of FBM to the ?-amyloid binding sites will help us better understand how FBM binds to plaques all over the brain.
