      Lai, Thu Hang; Schröder, Susann; Toussaint, Magali; Dukić-Stefanović, Sladjana; Kranz, Mathias; Ludwig, Friedrich-Alexander; Fischer, Steffen; Steinbach, Jörg; Deuther-Conrad, Winnie; Brust, Peter; Moldovan, Rareş-Petru (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-25)
      The adenosine A<sub>2A</sub> receptor (A<sub>2A</sub>R) represents a potential therapeutic target for neurodegenerative diseases. Aiming at the development of a positron emission tomography (PET) radiotracer to monitor changes of receptor density and/or occupancy during the A<sub>2A</sub>R-tailored therapy, we designed a library of fluorinated analogs based on a recently published lead compound ...
    • PET imaging of the adenosine A2A receptor in the rotenone-based mouse model of Parkinson’s disease with [18F]FESCH synthesized by a simplified two-step one-pot radiolabeling strategy 

      Schröder, Susann; Lai, Thu Hang; Toussaint, Magali; Kranz, Mathias; Chovsepian, Alexandra; Shang, Qi; Dukić-Stefanović, Sladjana; Deuther-Conrad, Winnie; Teodoro, Rodrigo; Wenzel, Barbara; Moldovan, Rareş-Petru; Pan-Montojo, Francisco; Brust, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-02)
      The adenosine A<sub>2A</sub> receptor (A<sub>2A</sub>R) is regarded as a particularly appropriate target for non-dopaminergic treatment of Parkinson’s disease (PD). An increased A<sub>2A</sub>R availability has been found in the human striatum at early stages of PD and in patients with PD and dyskinesias. The aim of this small animal positron emission tomography/magnetic resonance (PET/MR) imaging ...
    • Radiosynthesis and biological investigation of a novel fluorine-18 labeled benzoimidazotriazine- based radioligand for the imaging of phosphodiesterase 2A with positron emission tomography 

      Ritawidya, Rien; Wenzel, Barbara; Teodoro, Rodrigo; Toussaint, Magali; Kranz, Mathias; Deuther-Conrad, Winnie; Dukić-Stefanović, Sladjana; Ludwig, Friedrich-Alexander; Scheunemann, Matthias; Brust, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-15)
      A specific radioligand for the imaging of cyclic nucleotide phosphodiesterase 2A (PDE2A) via positron emission tomography (PET) would be helpful for research on the physiology and disease-related changes in the expression of this enzyme in the brain. In this report, the radiosynthesis of a novel PDE2A radioligand and the subsequent biological evaluation were described. Our prospective compound ...
    • Synthesis and biological evaluation of a novel 18F-labeled radiotracer for PET imaging of the adenosine A2A receptor 

      Lai, Thu Hang; Toussaint, Magali; Teodoro, Rodrigo; Dukić-Stefanović, Sladjana; Kranz, Mathias; Deuther-Conrad, Winnie; Moldovan, Rareş-Petru; Brust, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-25)
      The adenosine A<sub>2A</sub> receptor (A<sub>2A</sub>R) has emerged as a potential non-dopaminergic target for the treatment of Parkinson’s disease and, thus, the non-invasive imaging with positron emission tomography (PET) is of utmost importance to monitor the receptor expression and occupancy during an A<sub>2A</sub>R-tailored therapy. Aiming at the development of a PET radiotracer, we herein ...
