  • Patent number: 9309267
    Abstract: The present invention relates to novel derivatives that are suitable as precursors to compounds that are useful for imaging amyloid deposits in living patients, their compositions, methods of use and processes to make such compounds. The compounds deriving from these precursors are useful in methods of imaging amyloid deposits in brain in vivo to allow antemortem diagnosis of Alzheimer's disease by positron emission tomography (PET) as well as measuring clinical efficacy of Alzheimer's disease therapeutic agents. Furthermore, the present invention also discloses the precursor compounds in crystalline form.
    Type: Grant

  • Patent number: 6124278
    Abstract: Compounds based on the benzoxazine ring system that are remarkably more potent than corresponding benzoyl piperidines for enhancing synaptic responses mediated by AMPA receptors are disclosed, as are methods for the preparation thereof, and methods for their use for treatment of subjects suffering from impaired nervous or intellectual functioning due to deficiencies in the number of excitatory synapses or in the number of AMPA receptors. The invention compounds can also be used for the treatment of non-impaired subjects for enhancing performance in sensory-motor and cognitive tasks which depend on brain networks utilizing AMPA receptors and for improving memory encoding.
