摘要:
This invention provides novel cyclooxygenase-2 selective agents that are particularly useful as imaging probes in non-invasive imaging techniques, such as PET and SPECT. Preferred cyclooxygenase-2 selective agents inhibit cyclooxygenase-2 activity with greater potency and specificity than conventional cyclooxygenase-2 inhibitors. Other aspects of the invention include pharmaceutical compositions including the cyclooxygenase-2 selective agents as well as methods for detecting and/or inhibiting cyclooxygenase-2. These methods are particularly useful for diagnosing and treating disorders, such as inflammation, which is characterized by elevated cyclooxygenase-2 levels.
摘要:
A method for labeling structures, such as β-amyloid plaques and neurofibrillary tangles, in vivo or in vitro, is provided and comprises contacting brain tissue with one or more compounds, preferably radiolabeled for detection by positron emission tomography (PET).
摘要:
The invention provides a method for detecting or monitoring Alzheimer's disease and other forms of dementia using positron emission tomography (PET) or single-photon emission computed tomagraphy (SPECT) and radiolabeled, serotonin 5-HT1A receptor-specific tracers (such as [F-18]MPPF, [F-18]FCWAY, [C-11]WAY-100635, and other radiolabeled compounds having agonistic or antagonistic effect on serotonin receptors), for detection or monitoring of pathological changes (i.e., neuronal cell loss) associated with dementia.
