  • Publication number: 20220227728
    Abstract: The present invention discloses a series of nuclear medicine tracers that are combined with brain microtubule-associated protein Tau targeting compounds to produce a group of compounds of nuclear medicine that can be utilized for imaging of microtubule-associated protein Tau. When the positrons released by the decay encounter the electrons of the cells in the sample, utilizing the positron decay characteristics of fluorine-18 or iodine-124 isotope to generate mutual destruction reactions, a pair of opposite gamma rays is formed which are imaged by positron emission tomography. The compounds can be applied for the in vivo detection of microtubule-associated protein Tau deposits in the brain. The invention provides a strategy for diagnosis of Alzheimer's disease and a method to measure the efficacy of therapeutic drugs targeting microtubule-associated protein Tau.
